Roux-en-Y (RNY) gastric bypass is a type of weight-loss surgery in which the stomach is divided into a small upper pouch and a larger lower "remnant" portion. The small intestine is rearranged to connect to both. This reduces the stomach's capacity and alters how the body absorbs calories and nutrients, making it one of the most effective bariatric surgeries for long-term weight loss. Patients can expect significant weight loss, but the procedure is more complex than other forms of bariatric surgery, requiring... +More

The long-term effects of sleeve gastrectomy include sustained weight loss, improvement or resolution of obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea. However, patients may also experience long-term nutritional deficiencies, requiring them to take supplements like vitamin B12, calcium, and iron.

Unlike some bariatric procedures, the gastric sleeve is considered irreversible because a large portion of the stomach is permanently removed. While Turkey offers various bariatric revision surgeries, reversing a sleeve gastrectomy is not an option. However, other procedures, such as converting a sleeve into a gastric bypass, are available if patients experience complications or insufficient weight loss.

The diet after sleeve gastrectomy is crucial for recovery and long-term success. Patients start with a liquid diet, then gradually progress to pureed foods, soft foods, and eventually solid meals over several weeks. A focus on high-protein, low-carbohydrate, and nutrient-dense foods helps maintain weight loss and avoid deficiencies. Hydration and vitamin supplementation are also important aspects of the post-sleeve diet.

The most common cause of death was sepsis (33% of deaths), followed by cardiac causes (28%) and pulmonary embolism (17%).
