Gastric Sleeve: Understanding Risks and Complications

In recent years, gastric sleeve surgery has gained popularity as an effective treatment for obesity and related health conditions. Also known as sleeve gastrectomy, this procedure involves the surgical removal of a portion of the stomach to reduce its size and limit food intake. While هزینه عمل اسلیو معده surgery can be life-changing for many individuals struggling with obesity, it’s essential to understand that like any surgical procedure, it carries risks and potential complications.

Understanding Gastric Sleeve Surgery

Before delving into the risks and complications associated with gastric sleeve surgery, it’s crucial to understand how the procedure works. During a gastric sleeve surgery, the surgeon removes approximately 80% of the stomach, leaving behind a smaller, sleeve-shaped stomach pouch. This smaller stomach restricts the amount of food a person can eat, leading to reduced calorie intake and weight loss.

Gastric sleeve surgery is typically recommended for individuals with a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with obesity-related health conditions such as type 2 diabetes, hypertension, or obstructive sleep apnea. It is often considered a less invasive and irreversible alternative to other weight loss surgeries like gastric bypass.

Risks and Complications

While gastric sleeve surgery is generally safe and effective, like any surgical procedure, it carries certain risks and potential complications. It’s essential for patients considering this surgery to be aware of these risks and discuss them thoroughly with their healthcare provider.

1. Surgical Risks:

  • Bleeding: Excessive bleeding during or after surgery is a potential risk.
  • Infection: Infection at the site of the incision or within the abdominal cavity can occur.
  • Leakage: A leak along the staple line where the stomach is divided is a serious complication that may require additional surgery to repair.
  • Blood Clots: There’s a risk of developing blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism) after surgery.

2. Nutritional Deficiencies:

  • After gastric sleeve surgery, patients may be at risk of developing nutritional deficiencies, particularly in vitamins and minerals such as vitamin B12, iron, calcium, and folate. This is because the smaller stomach size may limit the absorption of nutrients from food.

3. Gastrointestinal Issues:

  • Gastroesophageal Reflux Disease (GERD): Some patients may experience symptoms of GERD, such as heartburn or acid reflux, following gastric sleeve surgery.
  • Nausea and Vomiting: Nausea and vomiting can occur, especially if patients eat too quickly or consume large amounts of food.

4. Psychological and Emotional Challenges:

  • Adjusting to the physical and lifestyle changes following gastric sleeve surgery can be emotionally challenging for some individuals. Patients may experience feelings of depression, anxiety, or body image issues as they navigate their weight loss journey.

Minimizing Risks and Maximizing Benefits

While gastric sleeve surgery carries risks and potential complications, many of these can be minimized with proper pre-operative preparation, post-operative care, and ongoing monitoring. Here are some steps patients can take to reduce their risk and optimize their outcomes:

  1. Choose an Experienced Surgeon: Select a surgeon who is experienced in performing gastric sleeve surgery and has a good track record of successful outcomes.
  2. Follow Pre-Operative Guidelines: Adhere to pre-operative guidelines provided by your healthcare team, which may include dietary changes, exercise recommendations, and medical evaluations.
  3. Commit to Post-Operative Care: Follow your surgeon’s instructions regarding diet, exercise, and lifestyle modifications after surgery. Attend all follow-up appointments and communicate any concerns or complications promptly.
  4. Attend Support Groups: Joining support groups or seeking counseling can be beneficial for emotional support and guidance throughout the weight loss journey.
  5. Adhere to Nutritional Guidelines: Work closely with a registered dietitian to develop a nutrition plan that meets your dietary needs and helps prevent nutritional deficiencies.


Gastric sleeve surgery can be a life-changing solution for individuals struggling with obesity and related health conditions. However, it’s essential to approach this decision with a clear understanding of the risks and potential complications involved.
