What Is Gaictric Sleeve Surgery?

Gastric sleeve surgery, also known as sleeve gastrectomy, is a significant surgical weight loss procedure that plays a critical role in helping individuals struggling with severe obesity to lose weight and enhance their health. It is a type of bariatric surgery performed to remove approximately 75-80% of the stomach, leaving it in the shape of a “sleeve” or a banana, hence the name ‘Gastric Sleeve’.

The fundamental purpose of gastric sleeve surgery is to restrict the amount of food the stomach can hold. As a result, this makes you feel fuller faster and thus reduces calorie intake, leading to weight loss. The operation also has the added benefit of significantly reducing hunger by eliminating the part of the stomach that produces the hunger-regulating hormone ghrelin.

While it is less invasive than gastric bypass surgery, gastris sleeve surgery is not without risks and potential complications, which include stomach leaking, blood clots, and nutritional deficiencies. Nevertheless, the profound impact it has on weight loss and the mitigation of obesity-related conditions such as diabetes, hypertension, and sleep apnea generally outweigh the potential risks for most patients.

Procedure of Gastric Sleeve Surgery

Gastric sleeve surgery is performed under general anesthesia and typically takes one to two hours. The surgeon makes several small incisions in the abdomen to insert a laparoscope—a small camera—and other surgical instruments. The surgeon then removes a large portion of the stomach and staples the remaining parts together to form a sleeve. After the surgery, the stomach is about the size of a banana and can only hold approximately three to five ounces of food at a time.

After the procedure, patients are generally required to stay in the hospital for a couple of days for monitoring before they can return home. Once released, they must follow a specific dietary plan that starts with only clear liquids and gradually introduces pureed and then solid foods. This process helps the body adapt to the newly sized stomach and prevents complications. Strenuous physical activities are discouraged for the first couple of weeks post-surgery; however, light exercise is promoted as a part of a healthy lifestyle changes.

Effectiveness of Gastric Sleeve Surgery

The effectiveness of gastric sleeve surgery as a weight loss tool is well documented. Generally, patients lose 50-70% of their excess weight within the first 1-2 years after surgery, which can be maintained with following a balanced diet and regular exercise. It’s beneficial impact on conditions like diabetes, sleep apnea, and hypertension has also been validated in numerous studies, with many patients experiencing reduction or even resolution of these conditions.

In cases where the sleeve gastrectomy does not yield the desired weight loss or when complications arise, an additional or ‘revisional’ procedure may be necessary. From the financial perspective, it’s worthwhile noting that the revisional weight loss surgery California cost can be significantly high. This cost generally ranges from $20,000 to $30,000, depending upon the complexity of the procedure and the healthcare provider.


In conclusion, gastric sleeve surgery is a potent tool in the fight against obesity. It significantly reduces your stomach size, restricts food consumption, and thus facilitates weight loss. Although the initial cost may seem high, and the lifestyle changes can be daunting, the apparent long-term benefits on weight and overall health make it a viable option for those dealing with severe obesity.
