Gastric Bypass: Solution for Severe Obesity
What Is Gastric Bypass Surgery?
Gastric bypass, also known as Roux-en-Y gastric bypass, is a highly effective bariatric surgery for individuals with severe obesity. The procedure reduces the size of the stomach and reroutes a portion of the small intestine, limiting food intake and reducing calorie absorption. This combination supports rapid and sustained weight loss.
How It Works
During gastric bypass surgery, the surgeon creates a small stomach pouch and connects it directly to the middle part of the small intestine. This bypasses a portion of the stomach and upper intestine, which:
Reduces the amount of food the stomach can hold
Decreases calorie and nutrient absorption
Alters gut hormones to reduce hunger and improve satiety
Benefits of Gastric Bypass Surgery
Significant and rapid weight loss, often greater than restrictive procedures
Improvement or resolution of obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea
Long-term maintenance of weight loss when combined with lifestyle changes
Positive impact on cardiovascular health and overall quality of life
