How Can I Calculate My Body Mass Index?

The body mass index (BMI) is a formula: weight (in kilos) / height 2 (in meters). It gives an idea of the degree of overweight and obese patients.

So as a result, we can classify obesity class I (BMI 30 to 35); Class II (BMI between 35 and 40); Morbid or class III (BMI 40 to 50); and Super Class IV or morbid obesity (BMI> 50).

This classification is defined in Argentina and the world the types of treatments that the obese patient needs.


Will post-surgery weight loss stop at any time?

* The decrease in weight after bariatric surgery is stabilized last year and a half, two years. Fortunately after that period have acquired new habits and behaviors is what allows the patient to stay at the right weight. Remember that surgery is a tool and it is not magic. All nutritional learning is required, that is, learning to select food, the quality, and quantity thereof. Incorporate physical activity is critical because it helps to keep weight down and makes us feel better. When the descent stops, they have spent many months in which the patient has been instructed and accompanied so you can incorporate all these habits in the best way.

Is it necessary to lose weight prior to surgery?

* The decline in pre-bariatric surgery weight is important. Once the patient enters the program, you are asked to descend about 10% of its weight. This is achieved by a low-calorie diet and a liquid diet the day before the surgery date. The intention is that the sharp drop in weight abdominal wall is less tense at the time of surgery and intra-abdominal fat too thin. This results in a lower technical complexity when operated and thus, less anesthesia time. Which will lead to a better immediate postoperative period? Also, the preoperative drop allows us to evaluate how the patient adheres to the guidelines set by the team, allowing us to know the patient and establish that it is a good candidate for this treatment.

What is my ideal weight?

* The ideal weight is defined as a cutoff point, i.e., that weight that allows the patient to have a body mass index (BMI) of 25 kg / m2. Recall that a BMI between 21 and 25 is normal. But we must stress that this is only an ideal. Which means it is not always possible to reach that weight or weight that is not right. So it’s important to establish that the ideal weight is the proper weight: minimum weight that maintain long term with proper diet, along with exercise and without oscillations.

What is metabolic syndrome?

* The metabolic syndrome is a cluster of diseases associated with obesity. They are high blood pressure, increased blood lipids (dyslipidemia) and diabetes or insulin resistance. This syndrome occurs in whole or in part in most of the morbidly obese. What is clear, is that also the majority of the time this syndrome improves or resolves completely after bariatric surgery. The mechanisms by which this occurs are complex and still not fully elucidated. In everyday life, improvement or resolution of this disease means that patients require fewer medications or should even suspend months following surgery. Keep in mind that it is shown that the lower the history of these diseases is a greater possibility that these will improve after surgery.

What are the risks for bariatric surgery?

* Bariatric surgery is major surgery, it is not without risks. Indicated to reduce the risk is operated with a team highly experienced in this field, which is multidisciplinary and give the patient all the necessary information. The surgeon’s experience is one of the key factors that largely reduces the risks of surgery. Adequate preoperative preparation is also important, achieving a decrease preoperative and understanding patterns improve outcomes. A multidisciplinary team trained in bariatric postoperative patient monitoring quickly detects any potential lessening the chance that complications develop.

Who are candidates for surgery?

* Patients with body mass index (BMI) greater than or equal to 40 kg / m2.
* Patients with BMI between 35 and 40 kg / m2 with high-risk comorbidities (diabetes, hypertension).
* Age between 18 and 65 years (although there are exceptions, and each case must be analyzed on an individual basis).
* Patients who have tried to lose weight by other methods, either diet, exercise and medication and failed.
* Patients willing to cooperate, taking a long-term commitment to attend to follow all the different areas of the team.
* Patients who demonstrate an understanding of surgical risk, and changes in lifestyle.

How will I continue to lose weight?

* A low-calorie diet supervised by a nutritionist our team starts.
* Following a liquid diet consisting primarily of water, tea, mate tea, decaffeinated coffee, light juices, defatted broth, orange juice, some fruits, milk, gelatin is indicated.
* Protein supplements, vitamins and proton pump inhibitors are added.
* It will indicate physical activity as much as possible.

How long must I continue the liquid diet?

* Approximately during 7-10 days before surgery. How is the diet after surgery?
* The 1st week will be on a liquid diet, which consist of water, tea, light juices, defatted broth and gelatin.
* Then they add different food every week.

Can I still exercise after surgery?

* Exercise is essential during weight reduction and maintenance post as it helps to expend calories, increases metabolism and lowers blood sugar and blood pressure.
* It is recommended that 30 to 40 minutes of exercise.

Should I enroll at a gym?

* Not necessarily. You can hike, bike, treadmill or simply get off measures as the collective one or two stops early, park your car further away, use the stairs instead of the elevator.

Will I get too thin after surgery?

* The body has regulatory mechanisms that prevent a decrease of excessive weight to the extent that patient compliance with diet performs maintenance and proper exercise.

I am interested in surgery, what should I do next?

* Consultation with the surgeon.
* Nutritional evaluation, clinical, and psychological.

What are preoperative studies?

* Chest X-rays.
* Lung function test.
* EKG and cardiac test.
* Echocardiography (selective).
* Polysomnogram or “sleep study” (selective).
* Upper endoscopy with biopsy to rule out the presence of Helicobacter pylori.
* Abdominal ultrasound.
* Complete Laboratory.
* Endocrinological evaluation (selective).

How long does the surgery take?

* Approximately 1 to 2 hours.

Will I experience pain post operation?

* Usually the postoperative period is not painful, but it depends on the susceptibility of each patient. The patient receives painkillers intravenously 24 hours and can also ask for “rescue” with other analgesics in the case of pain.

Will I have a drain?

* Yes. Drainage is the “informant” of what happens inside the abdomen during surgery. You can warn mainly about bleeding and leakage.
* The draw will remain for seven days after surgery.

How many days will I remain hospitalized?

* Approximately two days.

When will I start eating again?

* In the morning of the surgery, will begin testing tolerance to liquids, only water first, then with tea.
* At 15 days after surgery were added processed foods and one month after surgery began to “bite,” i.e., food will be added to be shredded by chewing.

What can I do when I get home, after a discharge from hospital?

* There are no restrictions except excessive weight lifting because any risk of herniation of the incisions.
* The patient should remain in business, making walking, treadmill or bicycle, thereby helping to reduce the risk of deep vein thrombosis.
* You can also bending, climbing stairs, bathing, sleeping on your side.
