Gastric Bypass Surgery
The basics: Roux-en-Y gastric bypass surgery is an operation that shrinks your stomach, along with the amount of calories and fat your body absorbs.
Who it’s good for:
People with severe reflux disease: Acid reflux often improves after gastric bypass surgery.
People with high BMIs: People lose more weight with gastric bypass.
People with diabetes.
Complications specific to gastric bypass include:
A higher risk of nutritional deficiencies due to bypassing part of your small intestine increased sensitivity to alcohol
Stomach ulcers
Bowel obstruction
Stomach perforation
Gastric Sleeve Surgery
The basics: Also known as the gastric sleeve, sleeve gastrectomy surgery involves operating only on the stomach. Surgeons remove around 80 to 85% of it, leaving a smaller “sleeve” in its place.
Who it’s good for:
People who have had multiple abdominal surgeries.
High-risk surgical patients: Sleeve gastrectomy is easier on patients than gastric bypass: The anaesthesia time is shorter, and the recovery is faster. High-risk patients include people with severe heart disease or lung problems, plus transplant candidates or recipients.
People who weigh more than 450 to 500 pounds: Too much fat can limit the amount of space inside the abdomen. Surgeons need room to reroute the GI tract.
People on multiple medications to treat psychiatric illness: Gastric bypass can affect how your body absorbs — and responds to — medications.
Complications specific to gastric sleeve surgery include:
Acid reflux
Leakage of stomach fluid
Narrowing (stenosis) along the stomach pouch
Stomach obstruction
