There are several options for weight loss or bariatric surgery and one of them is gastric sleeve weight loss surgery. This type of surgery is often recommended for patients with a BMI higher than 40. Patients who are extremely obese can undergo vertical sleeve gastrectomy, as it is also called, to allow them to reach a safer weight, after which they can have another bariatric surgery such as gastric bypass. A gastric sleeve operation is done laparoscopically or using small incisions, removing up to 85% of the stomach to reduce food intake.
How it Works
Using small incisions, the bariatric surgeon removes two-thirds or up to 85% of the patient’s stomach, so that the remaining stomach is in the shape of a tube or banana. Staples can be used to create a smaller stomach, which typically has a capacity of about 200 ml. With a smaller stomach, the patient can take in only small quantities of food.
Who is a Good Candidate for Gastric Sleeve Weight Loss Surgery?
Although the procedure is relatively new, gastric sleeve surgery is now one of the recommended weight loss procedures for patients with BMI higher than 40. The procedure can also be offered to individuals with BMI between 35 and 39 who have obesity-related health disorders such as diabetes and high blood pressure. It can also be offered to those who find it difficult or impossible to make the follow-up visits required by a procedure like gastric banding, which leaves a foreign object in the patient’s digestive system.
How Effective is Gastric Sleeve Surgery?
Most patients who have gastric sleeve surgery experience a weight loss of 50% to 80% of their body weight within 6 months to one year after surgery. Within two years, patients can lose an average of 60% of excess weight. One of the benefits of this bariatric procedure is that patients experience an improvement in blood pressure and cholesterol levels. Patients with diabetes and sleep apnea also show an improvement in their condition.
Comparison of Gastric Sleeve and Other Weight Loss Procedures
Unlike gastric bypass procedure, gastric sleeve surgery allows normal food digestion and absorption of nutrients, yet weight loss is about the same as that experienced by gastric bypass patients. In addition, the procedure is not as risky as a gastric bypass.
Gastric sleeve patients are also able to lose weight more quickly than those who have gastric band surgery. Being a relatively new procedure, however, there is limited data on long-term weight loss with gastric sleeve surgery compared to other procedures like gastric bypass.
Successful Weight Loss
People who have gastric sleeve surgery must make certain lifestyle changes in order to continue supporting weight loss. It’s true that the procedure creates a smaller stomach and forces you to eat less, but you will still have to exercise and eat a sensible diet in order to remain healthy and continue losing excess weight. Eating larger amounts of food can gradually stretch the stomach and make it bigger, thereby negating the effects of the weight loss procedure. Patients must commit to a healthy lifestyle and good eating habits.
