Gastric Sleeve

A sleeve gastrectomy is a weight-loss surgery that removes most of the stomach, creating a narrow tube-like structure. This procedure is typically done laparoscopically, using small instruments and making several small incisions in the upper abdomen. After the surgery, the remaining stomach will be about the size and shape of a banana.

Sleeve gastrectomy works to help you lose weight by reducing the size of your stomach, which means you will be able to eat less food. Additionally, this type of surgery prompts hormonal changes that aid in weight loss and also help to improve conditions often linked to being overweight, such as high blood pressure or heart disease.

What You Can Expect

During a sleeve gastrectomy, the patient is put under general anesthesia, which means they will be unconscious. The specifics of the surgery can vary depending on the patient’s circumstances and the surgeon’s approach.

While some sleeve gastrectomies are performed with a traditional large incision in the abdomen, the procedure is usually done laparoscopically using small instruments and multiple small incisions in the upper abdomen. During the surgery, the surgeon creates a narrow sleeve-shaped stomach by stapling it vertically and removing most of it.

The procedure will take one to two hours, and upon waking up, you will be in a recovery room where medical staff will closely monitor you for any potential complications. Your doctor may recommend that you remain in the hospital for a few days.


Sleeve gastrectomies can provide a lasting solution for weight loss, and the amount of weight loss can vary depending on the changes made to your lifestyle. These procedures can potentially help you lose 60% or more of excess weight within a two-year period.

  • Obstructive sleep apnea
  • High blood pressure
  • High cholesterol
