What is Gastric Sleeve Surgery?
Gastric sleeve surgery, or sleeve gastrectomy, is one of the most common bariatric surgeries worldwide. It is performed laparoscopically to remove a large portion of the stomach – around 70% to 90% – leaving the remaining section shaped like a narrow tube or “sleeve.”
That’s why some people call it sleeving surgery, which simply refers to the process of reshaping the stomach into a sleeve-like form.
The goal of this surgery is to reduce stomach size while preserving its normal digestive functions. This limits the amount of food and calories a person can consume in each meal and reduces the secretion of the hunger hormone ghrelin, helping the patient lose a significant amount of weight.
Advantages and Disadvantages of Gastric Sleeve Surgery
Gastric sleeve surgery is one of the most effective procedures for weight loss in people with severe obesity, especially when diet and exercise alone do not achieve satisfactory results. Just like any medical procedure, it has many benefits, but it also involves possible drawbacks or complications.
Advantages of Gastric Sleeve Surgery
- Significant excess weight loss: It helps patients lose a large percentage of their excess weight during the first 6 to 12 months after surgery.
- Improvement of obesity-related diseases: The procedure can greatly reduce or help treat conditions associated with obesity, such as:
- Type 2 diabetes
- High blood pressure
- Sleep disorders, such as sleep apnea
- High cholesterol and triglycerides
- No foreign body implantation or intestinal bypass: Unlike some other procedures such as gastric bypass, a sleeve gastrectomy does not involve inserting foreign objects or changing the path of the digestive system. It is considered simpler compared to bypass procedures.
- Improved quality of life: Weight loss and improved general health can lead to increased activity, better psychological well-being, and improved self-confidence.
- Reduced appetite: Because a large part of the stomach is removed, ghrelin levels decrease, reducing the feeling of hunger and helping lower food and calorie intake.
- Suitable for various age groups: It can be performed on patients of all ages, from 10 to 70 years, following a thorough evaluation by a qualified surgeon.
Disadvantages and Possible Complications
Although highly effective, gastric sleeve surgery may have side effects and complications that vary from person to person, including:
- Short-term side effects:
- Vomiting or nausea, especially in the first few months (particularly if the surgeon is inexperienced or a technical error occurs during surgery).
- Constipation or digestive disturbances.
- Dehydration due to reduced fluid intake.
- Later nutritional problems:
- Deficiency of certain vitamins and minerals, such as iron, vitamin B12, and calcium, if supplements are not taken regularly.
- Excessive loss of appetite, which may lead to malnutrition.
- Hair loss: This may occur in the first few months due to rapid dietary changes and weight loss.
- Loose skin: This may result from rapid weight reduction, especially in the abdomen, arms, and thighs.
- The need for a complete lifestyle change: Patients must follow a strict diet and maintain regular medical follow-up to avoid weight regain or complications.
- Stomach leakage: Rare but serious; this is prevented through meticulous surgical technique, high-quality tools, good preoperative preparation, and strict adherence to postoperative instructions.
Final Thought Regarding the Advantages and Disadvantages
Despite these possible side effects, the procedure is generally safe and provides excellent results. Many complications can be avoided through close follow-up with your doctor. Long-term studies show that gastric sleeve surgery is successful in achieving sustained weight loss and improving conditions such as type 2 diabetes and high blood pressure for more than 10 years.
Who is Eligible for Gastric Sleeve Surgery?
- People with severe obesity and a body mass index (BMI) of 40 or higher.
- People with a BMI between 35 and 39.9 who also suffer from weight-related diseases such as type 2 diabetes, high blood pressure, or sleep apnea.
- Select cases of severe obesity in children and adolescents, following a comprehensive medical evaluation.
- Patients with obesity-related health conditions, including high blood pressure, high cholesterol, diabetes, sleep apnea, and delayed childbearing—often due to polycystic ovary syndrome (PCOS) in women and reduced sperm quality in men.
- Patients diagnosed with metabolic syndrome, or obesity accompanied by diabetes or hypertension.
- Women with obesity who experience heavy menstrual bleeding.
- Postmenopausal women with obesity, as this option avoids affecting calcium absorption and thus helps reduce the risk of osteoporosis.
Contraindications: Candidates should not have a history of frequent or severe gastroesophageal reflux disease (GERD).
What to Expect After Surgery
Every body is different, so expectations after surgery vary from person to person. Some people lose weight quickly and significantly, while others lose weight more gradually.
On average, patients lose around 60% to 70% of their excess weight after gastric sleeve surgery. Here’s a rough timeline:
- First 45 days: About 20% to 30% of excess weight.
- Third month: About 35% to 45% of excess weight.
- Sixth month: About 50% to 60% of excess weight.
- Months 12 to 18: About 60% to 70% of excess weight.
Gastric Sleeve Operation Recovery Time
Most patients stay in the hospital for about 1–2 days and can usually return to normal daily activities within 2–4 weeks, depending on their job requirements and overall health status.
How to Prepare for Gastric Sleeve Surgery
Before surgery, the patient undergoes comprehensive testing, including blood panels, heart and lung function checks, and a nutritional evaluation. Patients are also advised to stop smoking well before surgery and avoid certain medications that may increase bleeding risk, such as non-steroidal anti-inflammatory drugs (NSAIDs).
It is also important to consider the psychological aspect. The patient should fully understand the procedure, including its benefits and possible side effects, as informed consent is essential before any surgery. A positive and supportive environment is highly recommended to help the patient before, during, and after the procedure.
Recovery After Gastric Sleeve Surgery
Before Leaving the Hospital:
- The patient usually stays in the hospital for one night under close observation.
- The patient is encouraged to move around and walk two hours after surgery to prevent blood clots.
- The patient begins drinking clear fluids 12 hours after surgery.
After Leaving the Hospital:
Because the surgery is laparoscopic, recovery is much shorter than with traditional open surgery. In general, patients can return to light desk work within a few days. After returning home, it is important to follow these instructions:
- Walk for 30 minutes daily for the first month.
- Avoid heavy physical effort, strenuous activities, and lifting heavy objects.
- Avoid smoking for at least two weeks.
- Avoid alcohol for at least one month.
Medical Follow-Up Schedule:
- First visit: One week after surgery.
- Second visit: Six weeks after surgery.
- Subsequent care: Regular monthly clinic visits or as advised by the medical team.
