What's the difference between gastric sleeve and gastric Bypass? Understanding the facts!
Difference between gastric sleeve and Bypass gastric - Procedure
Gastric sleeve surgery is a procedure that limits food intake during meals. During the procedure, 80% of the stomach is removed, and the remaining 20% is stitched into a banana-shaped pouch. This makes you feel fuller and helps you lose extra weight.
Gastric bypass surgery, or Roux-en-Y, is both restrictive and malabsorptive. It reduces food intake and prevents the body from consuming too many calories. The stomach is bypassed into a tiny pouch, and the intestine is cut and rearranged to create an outlet into the small stomach to maintain the flow of digestive juices.
Difference between gastric sleeve and gastric Bypass - Recovery
Both procedures are highly effective and minimally invasive surgeries with small incisions in the abdomen. Gastric sleeve is a one-step surgery, whereas gastric Bypass is a two-step weight loss surgery. Both procedures are done laparoscopically and require a minimum one to two-day hospital stay. Depending on the complexity of the surgery, the patients resume their routine activities after a few weeks or more.
Gastric Sleeve Vs Gastric Bypass - Complications
Bariatric surgery is generally safe, but with any surgery, there are a few expected complications, such as infection, blood clot, blood loss, postoperative pain, anaesthesia side effects, and pneumonia.
Gastric sleeve surgery is a simple procedure with a lesser chance of complications. Possible complications associated with gastric sleeve surgery include GERD or gastroesophageal reflux disorder.
Gastric Bypass is a complex procedure that increases the risk of nutrient deficiencies. The stomach and intestine are bypassed, which is essential for nutrient absorption. Possible complications after gastric Bypass include stomach ulcers.
Difference between gastric sleeve and gastric Bypass - Dietary changes
Both procedures require almost similar dietary changes after the treatment. You only have to consume liquids for the initial days after surgery. After the initial days, eat pureed foods and move on to soft foods. Consume soft foods for around four to six weeks. After six weeks, eat more foods according to the diet plan.
A few diet guidelines to follow after gastric sleeve or gastric bypass surgery,
- Eat smaller portions and stop when you’re feeling full
