The gastric sleeve procedure, also known as sleeve gastrectomy, is a surgical weight loss procedure that involves reducing the size of the stomach. It is designed to help individuals achieve significant weight loss and improve obesity-related health conditions.

Gastric sleeve surgery is typically performed using minimally invasive laparoscopic techniques, which involve making several small incisions instead of a large abdominal incision. This approach often results in shorter hospital stays, faster recovery times, and reduced post-operative pain compared to open surgery.

Gastric sleeve surgery has become increasingly common in recent years as a popular weight loss procedure. It has gained significant popularity and acceptance within the medical community as a safe and effective option for weight loss and management.


The exact prevalence or frequency of gastric sleeve surgeries can vary by region and healthcare systems. However, it is widely performed in many countries around the world. Gastric sleeve surgery is commonly performed as a standalone procedure or as part of a comprehensive bariatric surgery program.


Gastric sleeve surgery has gained popularity for several reasons. It is considered a relatively straightforward procedure with a lower risk profile compared to some other weight loss surgeries. Additionally, it offers significant weight loss results, helps improve obesity-related health conditions, and often leads to improvements in overall quality of life.


The decision to undergo gastric sleeve surgery is based on individual circumstances and factors, such as the severity of obesity, associated health conditions, previous weight loss attempts, and overall health. Candidates for gastric sleeve surgery typically undergo a comprehensive evaluation by healthcare professionals or bariatric surgeons to determine their eligibility and suitability for the procedure.

While weight loss itself can have positive effects on many medical conditions, gastric sleeve surgery specifically targets obesity-related conditions by promoting significant weight loss and metabolic changes. Here are some of the medical conditions that gastric sleeve surgery can help treat:


  1. Type 2 diabetes: Gastric sleeve surgery has shown to have a significant impact on improving or even resolving type 2 diabetes in many individuals. Weight loss and metabolic changes after surgery can lead to better blood sugar control and reduced reliance on diabetes medications.

  2. High blood pressure (hypertension): Hypertension is often associated with obesity. Gastric sleeve surgery can help lower blood pressure levels as weight loss occurs and improve overall cardiovascular health.

  3. Obstructive sleep apnea: Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep. Excess weight can contribute to the development or worsening of sleep apnea. Gastric sleeve surgery can lead to weight loss and reduction in sleep apnea severity.

  4. High cholesterol levels: Obesity can be associated with elevated cholesterol levels, including high LDL (bad) cholesterol and triglycerides. Gastric sleeve surgery, along with weight loss and lifestyle changes, can help improve cholesterol levels and reduce the risk of cardiovascular disease.

  5. Gastroesophageal reflux disease (GERD): Gastric sleeve surgery can improve or alleviate symptoms of GERD, a condition where stomach acid flows back into the esophagus, causing heartburn and discomfort. The surgery can help reduce the volume of stomach acid produced.

  6. Joint pain and osteoarthritis: Excess weight can put significant stress on the joints, leading to joint pain and osteoarthritis. By achieving weight loss through gastric sleeve surgery, individuals may experience reduced joint pain and improved mobility.

  7. Polycystic ovary syndrome (PCOS): PCOS is a hormonal disorder that affects women, often characterized by irregular periods, hormonal imbalances, and difficulties with fertility. Gastric sleeve surgery can help improve PCOS symptoms and increase the likelihood of successful conception.

Gastric sleeve surgery is generally considered a safe and effective weight loss procedure. However, as with any surgical procedure, there are potential risks and complications associated with gastric sleeve surgery. It’s important to understand both the benefits and the risks before making a decision. Here’s an overview of the safety considerations:


  1. Safety record: Gastric sleeve surgery has been performed for many years and has a generally favorable safety record. The procedure has undergone significant advancements, and improvements in surgical techniques and post-operative care have helped enhance patient safety.

  2. Surgical expertise: The safety of gastric sleeve surgery depends on the expertise and experience of the surgical team. It’s essential to choose a qualified and experienced bariatric surgeon who specializes in weight loss surgery and has a good track record of successful procedures.

  3. Potential risks and complications: Like any surgery, gastric sleeve surgery carries potential risks and complications. These can include infection, bleeding, blood clots, leaks at the surgical site, strictures (narrowing of the stomach outlet), gastrointestinal issues, nutrient deficiencies, and the need for follow-up surgeries. The risk of complications can vary based on individual factors such as overall health, surgical technique, and adherence to post-operative guidelines.

  4. Preoperative evaluation: Before undergoing gastric sleeve surgery, a thorough evaluation is conducted to assess your suitability for the procedure. This evaluation typically includes a review of your medical history, physical examination, and sometimes additional tests. This process helps identify any potential risk factors and determine the most appropriate course of action.

  5. Lifestyle changes and post-operative care: The success of gastric sleeve surgery relies on making lifelong lifestyle changes, including dietary modifications and regular physical activity. Following post-operative guidelines provided by your healthcare team is crucial for a safe recovery and long-term success.

  6. Individual considerations: The safety of gastric sleeve surgery can vary based on individual factors such as age, overall health, and the presence of other medical conditions. It’s important to have an open and honest discussion with your healthcare professional or bariatric surgeon to assess your individual circumstances, understand the potential risks, and determine if the procedure is appropriate for you.

WHAT they say


Gastric sleeve surgery, also known as sleeve gastrectomy, is a surgical procedure that involves reducing the size of the stomach by removing a large portion of it. This creates a smaller, sleeve-shaped stomach, which restricts the amount of food that can be eaten and promotes weight loss.

Gastric sleeve surgery helps with weight loss in several ways. By reducing the size of the stomach, it restricts the amount of food that can be consumed, leading to a feeling of fullness with smaller portions. Additionally, the surgery alters the production of certain hormones, such as ghrelin, which can help decrease appetite and promote weight loss.

The potential benefits of gastric sleeve surgery include significant weight loss, improved obesity-related health conditions (such as type 2 diabetes, high blood pressure, and sleep apnea), increased mobility, enhanced quality of life, and improved self-esteem and body image.

The duration of gastric sleeve surgery varies, but it typically takes around 1 to 2 hours, depending on individual factors and the surgical approach used.

Yes, dietary changes are an essential component of successful outcomes after gastric sleeve surgery. You will need to follow a specific diet progression, starting with clear liquids and gradually advancing to pureed, soft, and eventually solid foods. Your healthcare team will provide detailed guidelines and recommendations.

Recovery time can vary, but most individuals can expect to resume normal activities within 2 to 4 weeks after surgery. It’s important to follow the post-operative care instructions provided by your healthcare team and attend scheduled follow-up appointments.

Yes, after gastric sleeve surgery, you will likely need to take vitamin and mineral supplements to prevent nutrient deficiencies. This may include a multivitamin, calcium, vitamin D, iron, and vitamin B12. Regular monitoring of nutrient levels through blood tests may also be recommended.

Weight loss results can vary, but on average, individuals can expect to lose around 60% to 70% of their excess body weight within the first two years after surgery. It’s important to note that individual experiences may vary.
