Frequently Asked Questions

What are the benefits of sleeve gastrectomy?
  1. Significant weight loss. Patients have been shown to lose an average of 66% excess body weight in 3 years.
  2. Reduced healthcare costs.  A recent study showed that bariatric and metabolic surgery pays for itself in about 2 years. One important reason is that bariatric and metabolic surgery may help to improve or resolve conditions associated with obesity, such as type 2 diabetes and high cholesterol, so patients save money on related prescription drugs, doctor visits, and hospital visits.
  3. Quality-of-life improvements.  Clinical studies of laparoscopic bariatric and metabolic surgery patients found that they felt better, spent more time doing recreational and physical activities, benefited from enhanced productivity and economic opportunities, and had more self-confidence than they did prior to surgery.

How long does it take to recover from the sleeve gastrectomy procedure?
One study showed that patients often leave the hospital after 2 to 5 days. Recovery times vary, and recovery may take up to 6 or 8 weeks.

What are the risks and complications?

How much weight can I expect to lose with sleeve gastrectomy?
Patients have been shown to lose an average of 66% of their excess weight in 3 years.

What can I eat after a sleeve gastrectomy?
Sleeve gastrectomy patients can eat a wide variety of foods, in small portions. A typical meal in a bariatric and metabolic surgery diet includes protein-rich foods such as lean meat, eggs, low-fat dairy products (yogurt and cheese), starches and whole grains, fruits, and vegetables. Eating protein helps you feel fuller longer. You're advised to avoid desserts and other items with sugar listed as one of the first three ingredients. High-sugar, high-fat foods can derail your attempts to lose weight. You'll also want to be cautious with raw vegetables, fruits with skin, nuts, popcorn, tough meats, stringy foods, and crusty bread (bagels and pretzels), which may block the opening of your stomach.
