Learn about the Sleeve

The gastric sleeve is a weight loss operation. You may have heard it referred to as the ‘sleeve gastrectomy’ or ‘vertical sleeve gastrectomy’. It is a surgery that involves removing about 70 – 80% of the stomach. This procedure often helps patients lose a substantial amount of weight, which can be important in resolving health conditions like diabetes, sleep apnea, or high blood pressure.

The gastric sleeve is permanent: it is not adjustable or reversible.

The gastric sleeve is usually done laparoscopically, which means our surgeon uses several very small incisions to perform the operation. A large portion of the stomach is separated, and the remaining stomach is tube-shaped, similar to a banana.
The sleeve helps patients lose weight in several ways. The first way is by reducing the size of the stomach, patients often feel full after eating much smaller meals. They also report feeling full for a longer period of time after eating. Additionally, the portion of the stomach removed during the gastric sleeve procedure is responsible for producing a hormone called ghrelin, which is the hormone responsible for hunger.
Generally our sleeve patients stay in the hospital for 1 – 2 nights. That decision will be made after surgery, as we see how you’re healing. Depending on how physical your job is, some patients go back to work in a week and some take longer.
Right after surgery, you will be on a liquid diet while your stomach heals. You’ll then start introducing soft, pureed foods with the guidance of our team. As your body recovers and you adjust to eating again, we’ll work with you to start eating solid foods again. You’ll want to focus on small portions, and making sure to get all the protein and other nutrients you need. We will help you every step of the way, so you know what to eat to best succeed with your weight loss tool.

  • Generally the sleeve can be performed on patients with a BMI greater than 40, or patients with a BMI of 35-40 provided they have one or two medical conditions

  • Good candidates for the sleeve – or any bariatric surgery – have tried repeatedly to lose weight without success.

  • Health conditions related to obesity like high blood pressure, heart disease, sleep apnea, osteoarthritis, or type 2 diabetes can make the sleeve a good option

  • Patients with severe reflux may not be good candidates for the sleeve. The gastric bypass may be a better option in this case.
