Gastric sleeve surgery is one of the most commonly preferred surgical methods in the treatment of obesity. However, it is not possible for an individual to decide on this procedure alone. Whether a person is suitable for gastric sleeve surgery is determined after necessary medical examinations under the supervision of a specialist doctor. One of the most frequently asked questions by people considering surgery is the duration of the operation. The answer to the question “How long does gastric sleeve surgery take?” is very important for patients.

Generally, gastric sleeve surgery takes between 1 and 1.5 hours. In an average procedure, the surgical operation lasts approximately 60 minutes. Since this duration may vary for each patient, your doctor may not give a precise time estimate. The patient’s overall health condition, the surgeon’s experience, the technique used, and situations encountered during surgery all affect the duration.

Factors Affecting the Duration of Gastric Sleeve Surgery

Gastric sleeve surgery is mostly performed using the laparoscopic (closed) technique. In this method, a few small incisions are made in the abdominal area. Then, approximately 75–80% of the stomach is removed using specialized surgical instruments. The closed technique helps shorten the operation time. In addition, recovery after laparoscopic surgery is generally more comfortable for patients.

The patient’s general health condition also significantly affects the duration of the surgery. Additional conditions accompanying obesity, such as diabetes, hypertension, and sleep apnea, require the operation to be performed more carefully. Previous abdominal surgeries may also prolong the procedure. The surgeon’s level of experience is one of the most decisive factors in determining surgery time. An experienced surgeon can complete the operation more safely and in a more controlled manner.

What Is the Recovery Process Like After Surgery?

Just as the duration of gastric sleeve surgery is a matter of curiosity, the length of the recovery period after surgery is also frequently questioned. After the operation, patients are usually kept under observation in the hospital for 2 to 3 days. During this period, fluid intake, pain levels, and general health status are closely monitored.

In the first days after surgery, a liquid diet is followed as recommended by the doctor. In the following weeks, patients transition to pureed and soft foods. This allows the stomach to gradually adapt to its new volume. Adhering to the nutrition plan provided by the doctor and dietitian both accelerates recovery and ensures healthy weight loss.

Things to Consider Before and After Gastric Sleeve Surgery

The success of gastric sleeve surgery should not be attributed solely to the duration of the operation. Important points to consider before and after surgery include:

• Before surgery, patients must complete all required medical tests, pay attention to their diet, and follow the doctor’s recommendations.

• After surgery, regular follow-up appointments should not be neglected. This procedure is not only about reducing stomach size; a permanent lifestyle change is essential.

• Although the process may not be easy, patients can recover quickly with the support of their doctor and dietitian. Healthy eating, regular exercise, and psychological adaptation are crucial for a successful recovery.

What Are the Possible Risks and Complications of Gastric Sleeve Surgery?

Although gastric sleeve surgery is an effective and commonly preferred treatment for obesity, it may involve certain risks and complications. Being aware of these risks allows patients to approach the surgical process more consciously. Possible risks and complications include:

• Postoperative risks such as infection and bleeding. Infections may occur at surgical incision sites, and in rare cases, internal bleeding may develop.

• Due to general anesthesia, respiratory problems, allergic reactions, or heart rhythm disorders may occur.

• Leakage along the gastric stapler line is a serious but low-probability complication.

• Long-term complications are generally related to nutrition. Because stomach volume is reduced, deficiencies in vitamins and minerals may occur, especially vitamin B12, iron, and calcium.

• Gastric reflux, stomach ulcers, and gallstone formation may also appear in the long term. To minimize risks, the patient’s medical values should be thoroughly evaluated before surgery.

After surgery, patients must not skip doctor check-ups. Following the prescribed nutrition plan and taking necessary supplements significantly reduces the risk of complications. Close monitoring is essential to prevent or promptly manage potential risks.

Frequently Asked Questions (FAQ)

1. Who is not suitable for gastric sleeve surgery?

Gastric sleeve surgery may not be suitable for everyone with excess weight. Individuals with severe psychiatric disorders, active substance abuse, or those unable to adapt to postoperative lifestyle changes are generally not considered suitable candidates. Certain stomach and intestinal diseases may also prevent surgery. Suitability must be determined by a specialist doctor.

2. How much weight can I lose after gastric sleeve surgery?

Weight loss usually begins within the first weeks after surgery. The first 6 months is the period of fastest weight loss. By the end of one year, most patients lose a significant portion of their excess weight. However, the rate of weight loss varies depending on the individual, diet, and lifestyle.

3. Will I definitely lose weight with gastric sleeve surgery?

Gastric sleeve surgery is not a permanent solution on its own. While the operation reduces stomach size, long-term success depends on changing eating habits and maintaining regular physical activity. Weight regain may occur if unhealthy habits return.

4. Does the stomach expand again after surgery?

Technically, the stomach does not return to its original size. However, excessive and improper eating habits may cause the stomach to stretch over time. This can slow weight loss or lead to weight gain. Therefore, portion control and dietitian follow-up are very important.

5. Is pregnancy possible after gastric sleeve surgery?

Yes, pregnancy is possible after gastric sleeve surgery. However, it is generally recommended to wait at least 12–18 months after surgery. This period allows weight loss to stabilize and nutritional values to normalize. Pregnancy planning should always be done under medical supervision.
