Sleeve Gastrectomy

Sleeve gastrectomy is a type of bariatric (weight loss) surgery that treats obesity – a condition causing life-threatening heart disease, diabetes and stroke.

The procedure restricts what you can eat by surgically reducing your stomach size.

It may be an option if diet and exercise programs fail for people with a body mass index (BMI) of:

  • Your body mass index (BMI) is over 40.

  • You have a BMI of 35 to 39.9 and have two or more obesity associated conditions such as high blood pressure, sleep apnea, diabetes or heart disease.

It’s common to lose 50 to 70 percent of excess weight in a year or two after sleeve gastrectomy.

At Temple Health, weight loss surgery is just one part of a lifelong health plan. If you have this surgery, you’ll have a compassionate multidisciplinary team and motivating support groups. We help you lose weight and keep the weight off.

The Sleeve Gastrectomy Procedure

The sleeve gastrectomy is a restrictive procedure in which surgeons divide your stomach vertically, removing 80 to 85 percent of your stomach. This leaves a long, narrow sleeve about the size of a banana. The stomach nerves and outlet valve (pylorus) stay in place to preserve stomach functions. Doctors also remove the part of your stomach that makes ghrelin – an appetite-stimulating hormone. This helps to reduce your appetite.

If you have the sleeve gastrectomy, you’ll feel full after eating less food. This, combined with behavior modification and dietary compliance, will help you achieve successful weight loss. You’ll lose weight since you’re taking in fewer calories.

The Temple bariatric surgeons perform minimally invasive sleeve gastrectomy.

Diet After Surgery

If you have sleeve gastrectomy, you’ll be less hungry and feel full sooner. It’s important to chew food thoroughly and stop before you’re full. Overeating may cause nausea or stretch your stomach.

Just after surgery, you’ll drink liquids only – without carbonation, caffeine or sugar. In time, you can eat pureed foods and textured foods. By week four or five, you can have non-pureed soft foods.

Once you’re eating normal foods, diet guidelines include:

  • About a half-cup of food per meal

  • Avoiding alcohol and spicy, sugary or fibrous foods

  • High-protein foods before progressing to vegetables and fruits

  • Limited, low-calorie snacks 

  • No liquids with meals (empties stomach pouch, leaving you hungry)

  • Not overeating – quit when you’re almost full

  • Three small meals daily, eaten slowly

  • Water or calorie-free beverages – no carbonated liquids 

Your dietitian helps you plan balanced meals – including vegetables and fruit, low-fat proteins and heart-healthy fats, such as olive oil.

Benefits of Sleeve Gastrectomy

Advantages of sleeve gastrectomy include:

  • Your stomach is smaller, but you can still eat and digest most foods, in smaller amounts.

  • You can absorb most medications normally.

  • You will make a decreased amount of ghrelin, the appetite-increasing hormone.

  • There is no decreased chance of “dumping syndrome” – a bypass side effect when undigested food spills from your stomach pouch into the small intestine causing various symptoms.

  • There is a lower risk of ulcers, intestinal blockage, anemia, osteoporosis and malnutrition versus bypass surgery.

  • This is a minimally invasive laparoscopic procedure, which for many patients can mean a quicker recovery.

Complications, such as infection, are associated with any surgery. Learn more about sleeve gastrectomy risks or side effects.
