Configuring bariatric bodies : exploring obesity surgery beyond the hospital

Athenea Digital - num. 10: 103-120 (otoño 2006) ISSN: 1578-8946 Configuring bariatric bodies: exploring obesity surgery beyond the hospital Configurando cuerpos bariátricos: explorando la cirugía más allá del hospital Jordi Sanz Porras Faculty of Sociology (Lancaster University) [email protected] Resumen Abstract La cirugía bariàtrica deviene en muchos casos la última alternativa terapéutica para pacientes con obesidad mórbida grave. Basándose en una etnografía hospitalaria en la unidad de cirugía bariátrica, este artículo pretende explorar la configuración de los cuerpos para que la misma cirugía mantenga su status de tratamiento válido más allá del quirófano. Sin embargo, lo que en términos de restauración médica se llaman efectos colaterales, en términos de configuración corporal son nuevas relaciones semiótico-materiales que tienen en el quirófano su punto de partida. El sistema digestivo bariátrico no necesariamente encajará en el complejo de relaciones que lo sustenten tras dejar el hospital: el paciente deberá afrontar la (dis)capacidad de comer pequeñas porciones de comida y una deteriorada capacidad para absorber nutrientes. Bariatric surgery (surgery for obesity) is, in many cases, the last resort for the clinically overweight. Drawing on ethnographic materials in a unit of morbid obesity, this article explores how "bariatric bodies" are configured so that bariatric surgery is a sustainable solution beyond the operation theatre. However, what medicine calls ‘side-effects’, are, in terms of body configuration, a new set of semiotic-material relationships which start, but do not end, in the operating theatre. The bariatric digestive system might not necessarily fit with the set of relations with which it has to deal on leaving the hospital: the person will have to cope with eating very little, and with being able to ingest only a very limited amount of nutrients.

These kind of extensive surgical measures are major gastrointestinal operations that (a) seal off most of the stomach to reduce the amount of food one can eat and (b) rearrange the small intestine to 103 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras reduce the calories the bodies can absorb. Bile and pancreatic secretions, which are necessary for digestion of food, are directed away from the food. Drawing on ethnographical fieldwork in a unit of morbid obesity, this article explores how bariatric surgery is extended beyond the hospital by creating its own ‘bodies’, bariatrical bodies. My argument is that bariatric surgery is not only a restorative medical procedure but at the same time a body configuration process. What in terms of medical restoration are called ‘side-effects’, in terms of body configuration are a new set of semiotic-material relationships which have in the operation theatre their point of departure. The procedures undertaken by this kind of invasive treatment are not reversible and after leaving the operation room the person will be embedded with the (dis)ability to eat exclusively a small amount of food and a low capacity of nutrients assimilation. After leaving the hospital, bariatric surgery calls for a psychological preparation on the part of the patient and a fairly long period of adaptation to life with a small stomach and malabsorptive intestines. It compels patients to change their eating habits radically, and makes them very ill if they overeat. And after bariatric surgery is performed, patients remain at a lifelong risk of nutritional deficiencies. The higher the motivation of patients to lose weight, and manage the post-operative requirements of dietary modification and behavioural therapy, the more successful bariatric surgery is likely to be, in solving their obesity and weight related problems. Bariatric surgery as a treatment for morbid obesity Obesity is a wide-spread and life-shortening disease that can be defined as a pathologic accumulation of fat reserves described as one of the main hazards afflicting the Catalan society. Its rapidly widespread occurrence and increasing severity fit the criteria used to diagnose an epidemic. Obesity has been for too long considered simply as a case of an unbalanced energy budget, the emphasise being placed on the food intake. The association between food intake and obesity has been established in conjunction with sinfulness, lack of control and a delight in earthly pleasures. Due to the fact that these beliefs remain alive and deeply rooted in the minds of a large section of the Catalan society, an awareness of the dangers of obesity has been awakened by major medical practitioners. In spite of its epidemic character, no fully effective treatments are available. The strategies used to cope with obesity have relied mainly on the limitation of energy intake and/or energy expenditure. The most frequent method to limit energy is the administration of hypocaloric diets. The inhibition of the absorption of nutrients through specific digestive enzymes inhibitors has been also used. The effectiveness of this dietary regime is limited when facing morbid obesity although it has consolidated as the most extended therapeutic choice to treat overweigh. Secondly, the corollary assumption that obesity is a direct consequence of excessive food intake is that the obese remain as such because they lack of willpower to distance themselves from food: if they are obese is because they ingest more energy than needed and the rest becomes fat. Psychological conditioning has been used to maintain the obese far from food as much as possible, but results have been very poor. The focus on changing daily eating habits, removal of stressful influences and the morbid fear of becoming fat may help to monitor, but not to reduce, obesity. Some individual studies show how such approach can produce good initial weight loss and some degree of weight maintenance (Perri at al, 2000). Long term studies (Wilson, 1995; NHS Centre reviews and Dissemination, 1997; Odgen, 2003) contradict this Athenea Digital - num. 10: 103-120 (otoño 2006) 104 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras achievement: patients who lost weight initially regain it after three years and even may exacerbate problems with eating control and result in weight cycling and overeating. Surgery is the option used to produce a mechanical barrier to food intake and cope with the patients on which other treatments have failed. Bariatric surgery is constituted as the most common and extended way considered to effectively treating morbid obesity in Catalonia (although it is not appropriate to treat overweight people). But for many morbid obese, this kind of extensive surgery becomes the only way to improve in their condition. Generally speaking, bariatric surgical procedures are major gastrointestinal operations that (a) seal off most of the stomach to reduce the amount of food one can eat (only a limited amount of food can be eaten prior to getting full), and (b) rearrange the small intestine to reduce the calories the bodies can absorb. Bile and pancreatic secretions, which are necessary for digestion of food, are directed away from the food. These secretions reach the food several centimetres down the length of the small bowel, thus delaying and causing incomplete digestion and absorption of the food. Two of the most common types of surgery are Vertical Gastroplasty (VG) and Gastric Bypass. In VG, a small pouch is created at the top of the stomach and a small ring is placed at the bottom of the pouch, which acts as an artificial sphincter. This technique results in an average weight loss of 50% of excess body weight (Galibert & Kral, 2001). A more drastic procedure, Roux-n-y or Gastric Bypass, involves the complete partition of the stomach, creating a small pouch that is connected to the small bowel (Galibert & Kral, 2001). An average of 63% of excess body weight is lost as a result of Gastric bypass. A wide number of studies have been dedicated to demonstrate the effectiveness of the surgery in relation to long term weight lost and also the reduction in the risk factors for comorbidities associated with morbid obesity. For example, Jurgen Torgerson and Lars Sjostrom (2001) explored a 1000 matched pairs of patients, who received either surgery or conventional treatment for their obesity. Their results showed an average of 28 kgs in the surgical group after two years match up to only 0.5 kgs in the conventional group. A second example is the work of Nicholas Cristou et alt. (2004) which gave evidence about the reduction mean percent excess weight loss (67.1%, P < 0.001) in patients who undergone bariatric surgery. Furthermore, bariatric surgery patients had significant risk reductions for developing cardiovascular, cancer, endocrine, infectious, psychiatric, and mental disorders compared with controls, with the exception of hematologic (no difference) and digestive diseases (increased rates in the bariatric cohort). The mortality rate in the bariatric surgery cohort was 0.68% compared with 6.17% in controls (relative risk 0.11, 95% confidence interval 0.04-0.27), which translates to a reduction in the relative risk of death by 89%. Obesity surgery, however does not only affect weight. Some studies have made effort to demonstrate post operatives changes in aspects of the psychology of the patient such as quality of life, psychological morbidity and eating behaviour. In terms of health status and quality of life, especially in the patients who have achieved a sustain weight loss. The Cross sectional study John Boan et alt. (2004) reported improvements in weight related quality of life and physical activity. Important as well is Athenea Digital - num. 10: 103-120 (otoño 2006) 105 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras the work of Jorn Karlsoon et alt. (1998), who reported in a follow up study improvements in the health related quality of life operationalised in terms of mood disorders, mental well-being, health perceptions and social interaction. In terms of impact of surgery on aspects of eating behaviour, the empirical research points into a positive direction. Some studies show how post surgery patients decrease their hunger (Lang et alt., 2002), binge eating (Boan et alt., 2004) and external eating and flexible control (Lang et alt. 2002) In order to be qualified as a candidate for bariatric surgery, the patient must be 'morbidly obese', which means patients with a BMI > 40 kg/m2. Alternatively, patients with a BMI between 35-40 kg/m2 with severe comorbidities associated. Finally, patients with a BMI>30 Kg/m2 with associated pathologies that require important eating habits modifications (Chronic Renal insufficiency, Renal, Hepatic or Cardiac transplant). A second array of considerations are taken into account and these include: • Have participated repeatedly in medically-supervised attempts at weight management without maintenance of weight loss. • Demonstrate commitment to comprehensive medical and psychological evaluation before and after the surgery. • Agree to avoid pregnancy for at least one year after bariatric surgery. • Be capable of and willing to adhere to postoperative nutritional guidelines and exercise program. • Provide informed consent to surgery. The guidelines for the implementation of bariatric surgery are recapitulated in a protocol elaborated by endocrinologists, dieticians, gastric surgeons, psychiatrists, pneumologists and anaesthetists. Enacting the ‘bariatric user’: from restoration to configuration Agnes is 52 years old and she has a BMI of 42 with severe arterial hypertension and the Obstructive Sleep Apnoea Syndrome under control. Joseph is 25 years old and his BMI reaches 46 kg/m2 without any related comorbidity. These were the first two patients today in the welcome visit within the protocol. The endocrinologist repeated several times during the session that there is a long waiting list and this week surgeons are beginning to operate patients of 2003. I was curios which patient will go first and I asked the doctor. He explained me that they have to make a selection depending on patient’s attachment to the protocol. Sometimes was not purely the order of arrival and they have to see if the surgery is appropriate for the patient. We try to find out if the surgery will be worthy for a particular patient because there are many others waiting for the same opportunity. Waiting lists are present in a variety of situations and they are operated by public health centres to handle the access to healthcare services. Problems with large waiting lists and long waiting times affect in Catalonia all public hospitals and, more predominantly, those who are located near Barcelona. Since the first bariatric surgical intervention was performed in 1985 at Bellvitge Hospital in Barcelona, a lot has changed. In 2002, 503 bariatric operations were undertaken: 226 by in 10 public hospitals and 277 by 7 private hospitals. The social demand of bariatric surgery has abruptly increased during the last 5 years and today 0,5 % of the Catalan population is afflicted by morbid Athenea Digital - num. 10: 103-120 (otoño 2006) 106 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras obesity (30.000 patients). This is thought to be the cause of the fact that, in some Catalan hospitals, the time waiting for bariatric surgery is about 3 years. As Catherine Pope (1991) indicates, waiting lists are more than list of patients waiting their turn to receive treatment. Sometimes, they are used as an account to justify certain health policies that have they produced. They are instrumentals to response to the ‘social pressure’ to be seen as to be ‘doing something’ to improve the health system. When policy makers reduce waiting lists, they are working for the sake of the citizenship. The other side of the story are what Pope calls ‘individual theories’ that blame the actors caught up in the waiting list: patients, doctors and managers. Patients are blamed by messing up the queue for the surgery, cancel at short notice an appointment with the doctor or abuse the system. Doctors are blamed to favour none ‘urgent’ clinical cases and to ask for unnecessary diagnose tests (X-ray, blood analysis, scanners…). Managers are blamed to fail in conciliating health care needs and economic principles of efficiency. It has been also argued that in the absence of a market system waiting lists are used to ration scarce resources. Hospitals have been constrained by the government and rationing processes that operate via financial limits (availability of operation theatres, qualified personnel…). Spending in healthcare is not adequate to the social demand: waiting lists arise. As Pope (1991) points out, waiting lists are located at the base of the organisation, where the supplier meets the costumer. They are collectively administered by trained professionals as well as health professionals. They are a record of all the patients who have been referred for surgery, containing details of the proposed surgery, biographical data and the date of the referral. In the conventionality of the hospital, it is assumed that waiting for admission to the hospital is organised on a ‘first comes, first served’ basis. Patients’ details are kept on a chronological order waiting for their turn. But this does not mean that the earlier you arrive to the surgeon, the earlier you are operated. Tacit functioning of waiting lists show that both patients and doctors favoured dynamics of privilege creating distinctions between those who are able to jump the queue and those who wait their turn. Patient’s knowledge, internal relations of friendship, the use of private health… among others are explicative factors of access inequality. Doctors have a great power over the waiting lists because they are their property and have the ownership wrights. As such, they obtain benefits from them and they move patients in the way they consider more appropriate. Waiting lists provide the opportunity for doctors to deal with patients that obtain personally and professionally more satisfying work. A waiting list is essential to respond to technical advances of medicine and the new fashions in the treatments they can offer. Today there is an international course on bariatric surgery in the hospital and I have been invited to assist. One of the best bariatrical surgeons, Dr. Figueroa, will teach in a live sessions how to operate laparoscopically a gastric by-pass with mechanical anostomosis. Instead, as a condition for this operation, Dr. Figueroa wanted to incorporate an adjustable gastric band (AGB) to masculine patient with a BMI of 50 and with a binge eating disorder. Days after, one surgeon explained me how difficult the organisation of the course was. They couldn’t find a patient for the AGB. Fortunately, Lucy, the admissions manager, could find the AGB profile of a patient who entered in the waiting list two months ago. The surgeon acknowledged that this situation wasn’t fair, but he was captured by those who have the most advanced techniques. With this example, my intention is not overemphasize the power of doctors over the waiting lists. Doctors are bounded by protocols and major regulations. Procedures which routinely help them to Athenea Digital - num. 10: 103-120 (otoño 2006) 107 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras cope with the complexity of the waiting lists: the first to arrive to the hospital might not be the first patient who needs bariatric surgery. This is precisely the second framework in which my ethnography is taking place. As an official unit which surgically treats morbid obesity, the hospital is legally required to apply a protocol which includes fairness in the access to the treatment. According to Mark Berg (1998) protocols go beyond its nature of preformed recommendations issued for the purpose of decision-making in medical practice. They might help the health professional by analysing decisions before the fact and prevent the mental paralysis and chaos. They have also a normative dimension as the protocol ensures that the actions and interpretations of actions will have the same outcomes in any participating professional. They describe the good clinical reason in a way that becomes transferable, evaluable and scientific. In is the device by which order is brought into medical practice, which includes different professionals. Protocols integrate different medical specializations around the same ‘object’–morbid obesity. The implementation of a protocol is not simply a question of homogenizing medical practice by replacing “messiness with the orderliness of a ‘good’ medical practice X. […] A protocol is not an inert tool: its specific, formal structure transforms the order it transport in distinctive ways” (Berg, 1998: 228). This transformation affects both medical practice as well as patients. And this is precisely what changes: before becoming a patient, you are candidate. Athenea Digital - num. 10: 103-120 (otoño 2006) 108 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras It is Wednesday 15: 00 pm and I arrived a little bit late but the endocrinologist hasn’t begun with the first patient yet. I entered in the desk and I taked a chair. Dr Perez calls the first patient and a Judith goes in. She starts to explain that is 45 years old and wants to solve her problems with weight. Dr. Perez calculates her BMI. It is 45 kg/m2 and matches one of the eligibility criteria. He also asks if she has any obesity health related problem. She answers that arterial hypertension and knee pain (though she is not sure that if it’s due to morbid obesity). Dr Pérez nods and he gives to understand that Judith meets the physical requirements to be treated in the hospital. He explains that today he is not going to give her anything to do. First doctors want to know her a little bit, especially in the areas of eating habits and physical exercise. Dr Pérez also gives her a therapeutic contract so Judith signs it. Dr. Perez justifies it by saying that they have seen patients that have not done enough for the surgery. Once they are operated they go back to previous lifestyle and in the best cases, regain weigh. Sometimes, they have to be re operated because the pouch brakes because they eat food that his new digestive system is not prepared to process. The fragment above contains detailed criteria to be candidate as a precondition for becoming a bariatric patient. A BMI above 40 kg/m2 is only of the eligibility criteria to begin with the long trajectory to be include in the waiting list for bariatric surgery, waiting list in the hands of the surgeon who will operate the patient. Thus, protocols become a concatenation of obligatory points of passage for the candidate, for its body and for its morbid obesity. Protocols and waiting lists are two forms of dealing want we know as the “problem of diversity”. By enacting a typical patient trajectory, medical practice does not simply restore from illness to healthiness. Bariatric surgery selects its candidates: I was with Iñaki, a dietician that recently has started to work in the unit. Today we have been receiving patients that are still not operated but following a diet prescription prior to visit the surgeon. I was amazed how clear the boundary between allowed and prohibited food. So I asked him what would happen if a patient, who was vegetarian and, due to a thyroid disorder, applied for bariatric surgery because he is morbid obese. Iñaki took some seconds and asked me that this kind of surgery wasn’t for him. Operated patients have to eat a lot of meat and fish because they will experience difficulties in absorbing proteins. Their new digestive system passes by the area of small intestine where we normally absorb proteins. And selecting the candidate means preparing the candidate for the surgical operation, to the new digestive system and new life-style (eating habits and physical exercise). Following Steve Woolgar (1991), the implementation of a bariatric surgical technique includes configuring the user of such technique: defining, enabling and constraining. Bariatric surgery calls for a psychological preparation on the part of the patient and a fairly long period of adaptation to life with a small stomach and malabsorptive intestines. It compels patients to change their eating habits radically, and makes them very ill if they overeat. And after bariatric surgery is performed, patients remain at a lifelong risk of nutritional deficiencies. The higher the motivation of patients to lose weight, and manage the postoperative requirements of dietary modification and behavioural therapy, the more successful Bariatric surgery is likely to be, in solving their obesity and weight problems. The success of the bariatric surgical technique not only depends on the technique itself. I carried on drinking a quarter of litre of water and a quarter of a litre of peach juice every 24 hours. What happened was that my ability to smell highly developed and I could smell what was prepared in the kitchen: today fish or omelette… Well, I knew that this wasn’t for me but for other patients. For me, Athenea Digital - num. 10: 103-120 (otoño 2006) 109 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras it was enough with water and juice. I took a decision and cross the border and now I had to work hard to keep what was done within the operation room. I didn’t want to eat again for the rest of my life, because surgery only does the 50 % and the other half depends on you, yourself. You know… exercise and new eating habits. (Mary, 1234) The success of the technique depends on the mutual shape of the technique itself and its context of use. “The capacity and boundedness of the machine [technique] take their sense and meaning from the capacity and boundedness of the user” (Woolgar, 1991: 68). In configuring candidates as users, the protocol is establishing the parameters of their future actions. This means managing waiting lists and selecting the candidates that better shape the requirements of the ‘new digestive system’. I didn’t understand why pre-op patients are dieting if they have not visit the surgeon. I asked Iñaki and I couldn’t expect the answer: It is a rehearsal for the surgery. We trained them in the eating habits they will have as a post-op patient. We are conscious that is not easy to understand for the patient that he/she will not be able to eat more that a 40 grams of bread. It is not easy as well to avoid drinking before eating [If they do so, the pouch there is no place for food]. They need some time to do… you know this click! Change their mind. Before the candidate meets a surgeon, he must be a user as well. This is accomplished by relying on “usability trials”. “Even if a technology is a black box, such as a home stereo system, the user still has to know how to switch on the amplifier, how to connect the wires correctly, and under which conditions the machine can be used and so on. In general, the more the technology depends on the concern actions of human users for its successful operation, the more it will need to be tested in vivo” (Woolgar, 1991: 35-36). If we follow the protocol, when the patient leaves the welcome visit he will be assigned to a dietician who will be following the case individually for a period of nine months. The dietician will assess and monitor changes in the eating habits of the candidate according to the requirements of the surgical technique. In the meantime, the candidate will be seeing an endocrinologist as well. The pre-op usability trial has two differentiated processes at work. The first tries to converge the trajectory of the candidate to the trajectory of the ideal user. The second morally entitles the candidate with the label of user when the two trajectories melt. Converging trajectories implies making certain aspects present and certain aspects absent. It implies establishing preconditions for the surgery that become points of obligatory passage before visiting the surgeon and joining his waiting list. These give shape to the user of bariatric surgery and include: Clinical History: To consider risk factors in association with arterial hypertension, diabetes mellitus, dyslipidaemia, smoking habits, hyperuricemia, etc. Dietetic History: To review patient’s eating biography, eating patterns, amount of food consumption, sweet and alcoholic drinks. Eating habits and self-care: Frequency and time distribution of meals, grazing habits, eating at night, binge eating under an Athenea Digital - num. 10: 103-120 (otoño 2006) 110 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras episode of stress Physical Exercise: To capture the amount of physical activity during working time, in leisure time both daily and weekly. Fami8liar and Social environment: To understand psychiatric influences and familiar support Physical examination: BMI calculation, waist and hip perimeter, arterial pressure. The head of endocrinology reviews the general evolution of the patient during the last 9 months. He pays attention to the changes in the body weight and the evolution of the BMI. If the tendency has been a decline, this means that the candidate has been adhered to the dieting rules. He, then, [moral entitlement] deserves bariatric surgery: If you see they have lost at least 10 % of their initial weigh during this nine months, this means that they that they have been working hard. It is not easy to loose 15 kilos for someone who weights 130 kilos. This means that they are personally coherent enough to know what bariatric surgery is and what consequences for their life the operation will have. On the contrary is also true. If the candidate hasn’t lost enough weight, the body doesn’t lie. We are operating digestive systems and that’s why we include psychiatric evaluation prior to surgery. Once the candidate has the approval on the five dimensions the protocol requires, the head endocrinologist of the unit sends him to the surgeon. The surgeon will then evaluate if the weight loss is enough or the patient has to go back to the dietician: In this kind of invasive operations imply a high risk for the patient. We have to take this into account and see if the patient consciously knows about this. If you allow a candidate to visit the surgeon with the same BMI as in the beginning, you are harming other candidates that are also working hard. We have to prepare the body for the surgery. If the patient doesn’t reduce weight [15 kilos at least], this means concentration of fat in the stomach as well as in the liver. The surgeon will not use laparoscopy because the liver is too large for the camera to see with enough clarity. Also throcars can’t be fixed in patient’s abdomen and staplers are not long enough to arrive to the stomach. You know, with a laparotomy the risk for the patient increases and post-op recovery is longer and more painful. The decrease of the BMI is in the hands of endocrinology synonym of personal coherence, a guarantee of patient’s autonomy and of the ability to cope with the post-op eating habits. At the same time, the BMI determinates for the surgeon the kind of operation the patient will receive. In other terms, he sees BMI in terms of risk in the operation theatre. With a laparotomy, the risk for the patient is higher than a laparoscopy. Consequently, the surgeon prefers to send the patient back to the label of candidate (eating habits modification by medical supervised dieting) than to face any unpredictable complication during the operation. However, the responsibility of patient’s risk within the operation theatre has a second obligatory point of passage: the arterial gasometry test. The pressure of oxygen in blood (O2P) for a non morbid Athenea Digital - num. 10: 103-120 (otoño 2006) 111 Configuring bariatric bodies: exploring surgery beyond the hospital Jordi Sanz Porras digestive system. And this makes difference between having a surgery and living with a surgery. The bariatric digestive system becomes in this sense unpredictable, a fluid that always escape creating contours of elusiveness (pregnancy, domestic labour...). The digestive process might collude with the set of relations in which it is being enacted. And, specifically, with one of the preconditions by which all the surgical process began: the restitution of autonomy to a morbid obese patient. With this purpose, is when the notion of detachment takes in medical practice the form of a “preventive care”: in order to arrange and create links and connections between the new digestive system and those entities which contribute to the obduracy of the “normal body” though having intended disfuncionalities at work. These attempts allows the surgery be kept as a whole, in terms of maintained weight lost and patient’s personal autonomy. In relation to the extract above what becomes useful Moser and Law (1999) designate as the “theory of normalisation”. Preventive care for bariatric surgery relies on a systematic work to allow the patients to regain or develop their ability to function and master their lives, with the endeavour of giving them the highest degree of independence and quality of life. This is to say the patient as “identical to what we have learned to call ‘the modern, liberal, subject’: the independent, autonomous, centred, singular verbal and therefore competent subject (Moser, 2000: 209) Finally, preventive care implemented becomes highly asymmetrical. Asymmetrical because only incorporates a mode of digestive system. Preventive care is based in the assumption on a body that is discrete and bounded. Equally, bowel mal absorptive properties and a reduced stomach are contained within this body and affect it in multiple ways beyond the control of the patient. However, this body with its bariatric digestive system belongs to an individual, who is responsible of it. References Berg, Mark. (1998). Order(s) and disorder(s): of protocols and medical practices.
