Gastric Bypass

Gastric bypass is a procedure wherein the stomach’s larger part is bypassed, which means it no longer stores or digests food. There are two parts to the procedure. First, the surgeon creates a small stomach pouch by dividing the stomach’s top part (the pouch) from the rest of the stomach. The new pouch is approximately 30 milliliters and holds about 1 ounce (28 grams) of food.

During the second step (the bypass), the small intestine’s first portion is divided and the bottom end is connected to the newly created stomach pouch. Then the top portion of the divided small intestine is connected to the small intestine further down. This setup allows the digestive juices and stomach acids to mix with the food later in the digestive process.

There are several mechanisms involved in gastric bypass. First, similar to most bariatric surgical procedures, the newly created stomach pouch is smaller and can hold less food, which typically means less calories consumed. Additionally, because part of the small intestine is bypassed, the body absorbs fewer calories and nutrients from food. Most importantly, rerouting the food may change gut hormones, making you feel full with less food, suppress hunger and possibly improve Type 2 diabetes symptoms caused by obesity.

La cirugía de pérdida de peso se recomienda para personas con un índice de masa corporal (IMC) igual o superior a 35, independientemente de la presencia, ausencia o gravedad de las comorbilidades. La banda gástrica ajustable laparoscópica con banda gástrica® también está aprobada por la FDA para la cirugía de pérdida de peso en personas con un IMC de 30 a 35 que tienen al menos una afección relacionada con la obesidad. La cirugía para bajar de peso se considera segura, pero como muchos tipos de cirugía, tiene riesgos. Consulte con su médico sobre los riesgos y beneficios de la cirugía de pérdida de peso. Estos testimonios reflejan los resultados alcanzados por estos pacientes. Como cada caso debe evaluarse y manejarse de forma independiente, la pérdida de peso real variará.
