Roux-Y Gastric Bypass
Gastric bypass involves creating a gastric pouch and then connecting the small intestine with this gastric pouch. There are two ways of making this connection. In mini gastric bypass, it is done by making a single connection. However, in Roux-Y gastric bypass (RYGB), two connections are made.

The surgeon then cuts the small intestine and attaches the lower part of it directly to the newly created stomach pouch. This connection bypasses the separated larger remnant stomach and a portion of the small intestine hence, limiting the absorption of calories and nutrients. Then a new pathway for gastric acid is created by attaching the free end of the divided small intestine to a lower portion of the small intestine called jejunum. Hence the acid is diverted away from the smaller gastric pouch and food pipe. This diversion of gastric acid and bile protects the gastric pouch and connection from being exposed that could lead to gastric pouch inflammation or ulcers at the connection called marginal ulcers. Hence this difference makes the RYGB a safer option than an MGB especially for patients with known history of acid reflux or hiatal hernia. These connections create the “Y” shape that gives this technique its name. This helps you absorb fewer calories and nutrients. As a result, you feel full faster, eat less, and lose weight. RYGB is a good option for obese individuals especially for diabetics or those individuals with acid reflux disease. Following the procedure, patients typically stay in the hospital for a night or two for monitoring.

Laparoscopic Roux-Y Gastric Bypass Benefits
Gastric bypass surgery is a metabolic procedure that changes how your body responds to weight loss. When you lose weight through dieting, your brain senses the fat loss and it goes on survival mode by slowing down your metabolism, causing you to burn fewer calories. It also makes you feel more hungry and less satisfied after eating, which often leads to weight regain. However, with gastric bypass, the opposite happens. Your appetite decreases, you feel full faster, and your metabolism remains high, allowing you to burn more calories. This helps you lose a significant amount of weight and reach a lower metabolic and weight set point. As a result, RYGB can effectively resolve health issues like diabetes, high cholesterol, infertility, high blood pressure, and sleep apnea for many patients.

Other benefits of Laparoscopic Roux-Y Gastric Bypass includes
- 1It targets abdominal fat, a major risk factor for health conditions. It significantly impacts metabolic syndrome, improving or even resolving the cluster of conditions associated with increased risk of heart disease, stroke, and type 2 diabetes.
- 2With the RYGB procedure, the likelihood of experiencing acid-related heartburn symptoms is generally less than 1%. This means that the risk of experiencing discomfort or burning sensations in the chest due to acid reflux is quite low after the surgery.
- 3It has shown significant effectiveness in managing and even resolving type 2 diabetes. The procedure can lead to substantial improvements in blood sugar control and insulin sensitivity, resulting in a reduction or elimination of diabetes symptoms.
- 4The chances of developing ulcers following RYGB are typically less than 2%. Ulcers are open sores that can form in the stomach or small intestine, and they can cause pain and discomfort.
- 5This procedure is beneficial for individuals with hiatal hernia or inflammation in the lower food pipe. It effectively limits the amount of acid that flows into the food pipe, providing relief and helping to alleviate symptoms associated with these conditions.
