Gastric Bypass St Louis, MO
The Roux-en-Y Gastric Bypass, also known as gastric bypass, is regarded as the “gold standard” of weight loss surgery. Developed in the mid-20th century, it was the first bariatric procedure to become widespread. The gastric bypass in St Louis, MO, has saved countless lives and has proven to be highly effective at treating morbid obesity.
The procedure is divided into two parts. To begin, a small stomach pouch of about one ounce or 30 milliliters in volume is formed by separating the top of the stomach from the rest of the stomach. The first segment of the small intestine is divided, and the bottom end of the divided small intestine is brought up and connected to the newly formed small stomach pouch. The surgeon finishes the procedure by connecting the top portion of the divided small intestine to the small intestine further down, allowing stomach acids and digestive enzymes from the bypassed stomach and the first portion of the small intestine to mix with the food eventually.
How does Gastric Bypass Surgery Work?
The gastric bypass produces weight loss through two mechanisms: restrictive and malabsorptive. First, as with most bariatric procedures, the newly created stomach pouch is significantly smaller and allows for considerably smaller meals, resulting in fewer calories consumed. Moreover, because the smaller stomach pouch digests less food and a segment of the small intestine that would normally absorb calories and nutrients no longer has food passing through it, there is less absorption of calories and nutrients.
Rerouting the food stream alters gut hormones, promoting satiety, suppressing hunger, and reversing one of the primary mechanisms by which obesity causes type 2 diabetes.

Advantages of Gastric Bypass
- Long-term weight loss is significant (60 to 80 percent excess weight loss)
- Limits the amount of food that can be eaten
- Changes in gut hormones that decrease appetite and increase satiety
- A typical excess weight loss of more than 50% is maintained.
