Gastric Bypass (GB)

Overview
‍

Gastric Bypass surgery promotes weight loss by creating a small stomach pouch and connecting it to the Roux limb of the small intestine. This limits food intake and induces malabsorption by bypassing part of the stomach and small intestine, reducing calorie absorption.

This dual mechanism helps patients lose weight more effectively while also triggering hormonal changes that regulate hunger and metabolism. Gastric Bypass is a well-established procedure that has helped many individuals achieve long-term weight loss and improve obesity-related health conditions such as diabetes, hypertension, and acid reflux.

Who is it for?
‍

‍
Gastric Bypass is recommended for individuals with severe obesity who have struggled with weight loss through diet and exercise. It is especially beneficial for patients with a high BMI and metabolic conditions.

This procedure is commonly chosen by those with type 2 diabetes, severe acid reflux, or other obesity-related health issues. Gastric Bypass not only aids in weight loss but also helps improve co-morbidities like diabetes and hypertension, often showing benefits even before significant weight loss occurs.

Procedure Details

‍

During Gastric Bypass, the stomach is divided into a small pouch, and the small intestine is rerouted to connect with it. This process reduces stomach capacity and alters nutrient absorption.

• Anesthesia is administered and laparoscopic access is established.
• The stomach is divided, creating a small pouch.The small intestine is rerouted and connected to the pouch, forming the Roux limb.
• The remaining stomach and intestine are bypassed to induce malabsorption.
• The procedure is tested for leaks and incisions are closed.

Recovery and Aftercare

‍

Recovery from Gastric Bypass takes time as the body adapts to a smaller stomach and rerouted digestion. Most patients resume light activities within weeks, but healing takes longer and involves more pain than a Gastric Sleeve. Recovery starts with a liquid diet, gradually progressing to pureed and solid foods.

Long-term care includes regular medical check-ups, lifelong vitamin supplementation, and a structured meal plan to compensate for reduced nutrient absorption. There is a risk of developing ulcers, especially with NSAID or tobacco use, as well as small bowel complications and obstruction. Some patients may experience dumping syndrome, a feeling of sickness after eating or drinking, particularly sweets. We provide ongoing support to help patients adapt to new eating habits and maintain successful weight loss.

Results Timeline

‍

Significant weight loss begins within the first few months, with most patients losing 60-80% of their excess weight within a year. The most dramatic changes occur during the first six months.

Beyond weight loss, improvements in diabetes, hypertension, and acid reflux often appear within weeks. Continued success depends on maintaining a healthy lifestyle, with steady progress observed up to two years post-surgery.
