Sleeve Gastrectomy Frequently Asked Questions


What is sleeve gastrectomy?

In sleeve gastrectomy, part of the stomach is removed. The remaining section of the stomach is formed into a tube-like structure. This smaller stomach cannot hold as much food and produces less of the appetite-regulating hormone ghrelin, which may decrease your appetite. However, sleeve gastrectomy does not affect the absorption of calories and nutrients in the intestines.

What are the benefits of sleeve gastrectomy?

In addition to weight loss, sleeve gastrectomy has been shown to reduce conditions that commonly accompany obesity, such as Type 2 diabetes, high cholesterol, high blood pressure and obstructive sleep apnea. Not just better for your health, it is better for your budget— it saves money on prescription drugs, doctor and hospital visits. In addition, laparoscopic techniques mean minimal scarring and shorter hospital stays.

How much weight will I lose with sleeve gastrectomy?

Sleeve gastrectomy patients have been shown to lose an average of 66% excess weight in 3 years.

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 can I eat after a sleeve gastrectomy?

Sleeve gastrectomy patients can eat a wide variety of foods, in small portions. Avoid desserts and high-sugar, high-fat foods, which can derail your attempts to lose weight. You'll also want to avoid raw vegetables, fruits with skin, nuts, popcorn, tough meats, stringy foods, and crusty bread (bagels and pretzels), which may block with the opening of your stomach.
