Who can benefit? Gastrectomy surgery is currently one of the best treatments to achieve lasting weight loss in obese patients who have failed nonsurgical weight reduction methods. (Source: Dr. John Mcdougall). The candidates in power for a gastrectomy, are: persons with an index of Corporal mass (BMI) greater than 40 men who weigh 45 pounds more than its ideal weight or women who weigh 36 kilos more than his ideal weight people with a BMI between 35 and 40 suffering from another disease associated with obesity such as diabetes type 2, apnoea sleep, heart disease, hypertension, osteoporosis, etc. Gastrectomy is also a technique that can be used as a first step in patients at high risk, in order to achieve a weight loss and reduction of risks, prior to performing a supplementary surgery like ByPass Gastric. How much weight will I lose? Weight loss is achieved by restricting the amount of food that can be consumed. Gastrectomy technique shows a decrease in weight of 65-70% of overweight at 5 years of follow-up. The decrease in weight is more significant in the 1st post-operative year. They are frequent losses of 5 kg. per month during the first few months, then go to lowering loss until 12-18 months.
A success is considered if half of existing overweight is lost and the interventions most outgrow it. In some speeches some patients recovered part of the lost weight. No intervention gives a 100% success to all patients. I’ll be back to gain weight then? Cases, can occur since gastrectomy is a medium (mechanical) to control what he eats but he is not used to treat other psychological aspects of the disease. Therefore, to avoid a subsequent intervention failure, needs the cooperation of the patient and adjust your lifestyle to the new conditions deriving from this intervention, for which you will be given a dietary program to meet your needs for nutrition and vitamins.
