It is a type of weight loss surgery that involves creating a small sac from the stomach and connecting the newly created sac directly to the small intestine. After gastric bypass, the ingested food will enter this small stomach sac and then go directly to the small intestine, thus bypassing most of the stomach and the first section of the small intestine. The procedure lasts approximately 1 to 2 hours and is performed laparoscopically, 4 small incisions will be made to access the intra-abdominal cavity.
This procedure is indicated for those people who have tried to lose weight with diet and exercise and have not been successful, and also for those who are at risk of suffering from cardiovascular diseases or who already present them, people with diabetes and any condition that puts them into risk to the patient due to excessive weight bypass is indicated, those patients with a body mass index greater than 40 or more (extreme obesity) also. If your body mass index is 35 to 39.9 (obesity), and you have a serious weight-related health problem, such as type 2 diabetes, high blood pressure, or severe sleep apnea.
The associated risks are similar to any abdominal surgery, they are infrequent and all measures are taken so that these do not occur. They may include the following: excessive bleeding, infection, adverse reactions to anesthesia, blood clots, lung and breathing problems.
Later, after gastric bypass surgery, the patient will begin to consume only liquids, not solid foods, while the stomach and intestines begin to heal. Then a special meal plan will need to be followed to slowly transition from liquids to pureed foods. Later, can eat soft foods and then move to more solid foods, as the body can tolerate them.
Whether in any of these procedures, the patient must follow a diet plan and exercise, as well as change to a healthier lifestyle to help achieve their goals, they must maintain them to avoid gaining weight again.
