What is a Gastric Sleeve?

A gastric sleeve is a surgical procedure used to treat obesity. In this procedure, the stomach is reduced in size, creating a narrow tube-like structure. A large portion of the stomach is surgically removed, leaving only a tube-shaped area. With a smaller stomach, a person experiences a feeling of fullness by eating less, reducing calorie intake.

Gastric sleeve surgery is a surgical procedure within the scope of obesity surgery that reduces the size of the stomach and promotes weight loss. Also known as a weight-loss surgery , approximately 80% of the stomach is removed laparoscopically, leaving a long, thin, tube-shaped stomach. Because the stomach is smaller, patients eat less and feel full faster.

How is Gastric Sleeve Surgery (Stomach Reduction Surgery) Performed?

Gastric sleeve surgery (stomach reduction surgery) is performed laparoscopically (closed) for most patients. Patients receive general anesthesia before the surgery and feel no pain during the procedure.

Gastric Sleeve Surgery : This procedure uses specialized surgical instruments to reduce the size of the stomach into a tube. The surgeon makes several small incisions, measuring 0.5-1 cm, in the abdomen. A laparoscope (camera) is inserted through one of these incisions, while the other is used to insert surgical instruments.

Gastric Reduction : The majority of the stomach (approximately 75-80%) is surgically removed, and the surgeon reshapes the stomach into a thin tube, leaving only a tube-shaped stomach. During this procedure, stitches are placed in the stomach wall. The surgeon reshapes the stomach and stitches the area that formed the gastric sleeve closed. The reduction preserves the blood vessels and nerves, preserving stomach function. Following the surgery, the patient begins a recovery period, begins liquids, and gradually transitions to solid foods.

After Gastric Sleeve Surgery (Stomach Reduction) and Recovery Process

Nutrition is extremely important after gastric sleeve surgery  . The most important thing to consider after surgery is a complete change in eating habits. Liquids should be consumed in the first weeks after surgery, and a gradual transition to purees and solid foods should be made in the following weeks. Initially, small portions should be consumed to allow the stomach to adjust to its new size, and each bite should be chewed slowly. Post-operative vitamin and mineral deficiencies should also be considered, and it's crucial to carefully consume any vitamin supplements prescribed by your doctor.

Liquid Nutrition Process After Gastric Sleeve Surgery

 For the first few days after gastric sleeve surgery , it is recommended to consume only liquids. During this period, it is important for patients to consume liquids such as water, soup, and clear fruit juice to maintain adequate hydration and nutritional support. The liquid diet will intensify as the stomach begins to heal, and it will take approximately two weeks before the transition to solid foods begins. Fluid intake should be monitored meticulously to prevent dehydration and accelerate the healing process.

Weight Loss After Gastric Sleeve Surgery

After gastric sleeve surgery , patients typically experience rapid weight loss in the first six months. With a smaller stomach, patients feel fuller on less food, and they continue to lose weight through healthy eating and exercise. However, weight loss slows over time, and a significant weight loss is typically achieved within one year. Ongoing monitoring and lifestyle changes are key to achieving long-term success.

Frequently Asked Questions

What are the risks and side effects of gastric sleeve surgery (stomach reduction)?

Like any surgical procedure, gastric sleeve surgery carries risks. As with many surgical procedures, complications such as infection, bleeding, and leakage are possible. Additionally, some patients may experience side effects such as heartburn, nausea, and vomiting. However, these risks can be minimized by carefully following your doctor's instructions before and after surgery.

Long-term risks of this surgery include vitamin and mineral deficiencies. It's important to have your blood levels checked regularly afterward and take vitamin supplements if necessary.

Revision Surgery After Gastric Sleeve (Bariatric Surgery)

After bariatric surgery  , some patients may not achieve the expected results of the initial surgery or may experience weight gain over time. In these cases,  revision surgery  may be necessary. Revision surgery is a procedure performed when weight loss after the initial surgery is insufficient, complications occur, or stomach enlargement occurs. Revision surgery can help patients improve their health and achieve long-term weight management.

Will I Gain Weight Again After Gastric Sleeve Surgery (Stomach Reduction)?

Weight loss after gastric sleeve surgery  usually begins quickly, but some patients may regain weight over the long term. This is often associated with poor eating habits, neglecting portion control, or insufficient physical activity. The success of the surgery is directly linked not only to the surgery itself but also to the patient's adoption of a healthy lifestyle. Regular exercise, a balanced diet, and psychological support can help prevent weight gain. In conclusion, gastric sleeve surgery alone does not result in permanent weight loss; lifestyle changes and ongoing monitoring enhance the success of this process.

Will There Be Any Scars After Gastric Sleeve (Stomach Reduction) Surgery?

Gastric sleeve surgery is usually performed laparoscopically, meaning several small incisions are made in the abdomen and the surgery is performed through these incisions. This results in scars that are usually very small and fade considerably over time. However, as with any surgical procedure, the healing process varies from person to person, and the visibility of scars can vary depending on individual skin type and body reactions. With proper wound care, as recommended by your doctor, scarring can be minimized.

Can You Eat Cookies After Gastric Sleeve (Stomach Reduction) Surgery?

After gastric sleeve surgery, because the stomach volume decreases, dietary habits must be carefully adjusted. It is recommended to avoid high-calorie, hard-to-digest snacks like cookies after surgery. Because they are high in fat and salt, excessive consumption of cookies can negatively impact weight loss. However, healthy, low-calorie snacks (such as almonds or walnuts) can be enjoyed in moderation and with careful portion control.

Will There Be Hair Loss After Gastric Sleeve (Stomach Reduction) Surgery?

Some patients may experience hair loss during the weight loss process following gastric sleeve surgery. This is typically caused by rapid post-operative weight loss, inadequate protein intake, or the stress of the body's recovery process. However, this loss is usually temporary, and hair begins to regrow within a few months. To minimize hair loss, it's crucial to consume adequate protein and take regular vitamin supplements. Following your doctor's recommended dietary guidelines will support healthy hair growth.

How Should Vitamin and Mineral Supplements Be After Gastric Sleeve Surgery?

Because the stomach volume decreases after gastric sleeve surgery, nutritional intake becomes limited, which can lead to vitamin and mineral deficiencies. It's important for patients to regularly  take supplements such as multivitamins ,  iron ,  calcium ,  vitamin B12  , and  folic acid in the post-operative period  . Additionally,  careful attention to protein intake  is essential to prevent muscle loss and support the healing process. Taking the correct dosage of supplements, as recommended by your doctor, and preventing deficiencies through regular checkups are crucial for healthy weight loss.

Should You Exercise After Gastric Sleeve Surgery?

Exercise after gastric sleeve surgery is an important step to promote weight loss and improve overall health. However, strenuous exercise should be avoided for the first few weeks after surgery and should begin with low-intensity activities, such as light walking, as recommended by your doctor. Exercise intensity can be increased over time, depending on your recovery. Regular exercise helps prevent muscle loss, boosts metabolism, and helps tone your body. In summary, exercise, as part of a healthy lifestyle, is a key factor in long-term success after gastric sleeve surgery.

How long does gastric sleeve surgery take?

Laparoscopic gastric sleeve surgery takes approximately 1-2 hours.

Is it possible to get pregnant after gastric sleeve surgery?

Doctors generally recommend waiting at least 12-18 months after gastric sleeve surgery . This period is important for the body to complete the weight loss process and reach a healthier state for pregnancy.

How many days do you stay in the hospital after surgery?

The hospital stay after gastric sleeve surgery  is 2-3 days .

Will the stomach grow back after surgery?

Yes, if a patient returns to unhealthy eating habits and doesn't pay attention to portion control, the stomach can stretch and expand over time. Therefore, it's crucial to follow the diet and lifestyle changes recommended by your doctor.

What foods are prohibited after surgery?

• Carbonated drinks (can cause bloating and stomach distension)
• Sugary and high-calorie foods (can cause rapid weight gain)
• High-fat foods (can cause indigestion and stomach problems)
