For those who are severely obese, bariatric weight loss surgeryalso known as weight loss surgeryhas emerged as a vital option. This guide will examine the many kinds of bariatric surgery, along with the advantages, dangers, and pre-, intra-, and post-operative expectations.

A variety of surgical techniques are included in bariatric weight reduction surgery, which is intended to assist patients in losing a large amount of weight. By changing the digestive tract, these operations can lower food intake, absorption, or both. Helping patients reach and maintain a healthier weight is the ultimate objective because it can enhance their general health and quality of life.

Bariatric Weight Loss Surgery Types

There are varias opciones de cirugía bariátrica para bajar de peso, each with special advantages and methods. The most typical kinds consist of:

  1. Roux-en-Y Gastric Bypass (Gastric Bypass): A small stomach pouch is created during gastric bypass surgery, and the small intestine is rerouted to attach to this new pouch. This process lowers nutritional absorption and restricts food intake. In addition to being one of the best operations for long-term weight loss, it also seems to help with illnesses like diabetes and hypertension.
  2. Gastric Sleeve Surgery: After a sleeve gastrectomy, only a tiny, sleeve-shaped stomach is left behind after about 75% of the stomach is removed. The stomach’s capacity is drastically decreased by this surgery, which results in less food being consumed. Additionally, it has an impact on hunger hormones, which may lessen appetite. Significant weight loss can be achieved with a sleeve gastrectomy, which is less complicated than a gastric bypass.
  3. Lap-band surgery with adjustable gastric banding: In order to produce a tiny stomach pouch, this surgery entails wrapping an inflatable band around the upper portion of the stomach. The stomach’s capacity to hold food can be managed by adjusting the band. Despite being minimally invasive and adjustable, it frequently causes slower weight loss than other operations and may need more follow-up adjustments.
  4. Duodenal switch with bilipancreatic diversion (BPD/DS): A sleeve gastrectomy and a large part of the small intestine are bypassed during the BPD/DS operation. This procedure lowers the absorption of nutrients while simultaneously limiting food intake. Although it offers significant weight loss and is usually advised for those who are extremely obese, there is a greater chance of nutritional inadequacies.
