If you’ve been considering bariatric surgery, you’ve likely heard about sleeve gastrectomy. This procedure has become one of the most popular weight loss surgeries worldwide thanks to its effectiveness, safety, and long-term results. At The Weight Loss Surgery Center of Los Angeles, we help patients understand their options and decide if sleeve gastrectomy is the right path. Here are seven important things to know about the procedure.
1. Sleeve Gastrectomy Is Performed Laparoscopically
One of the biggest advantages of sleeve gastrectomy is that it’s a minimally invasive laparoscopic procedure. Surgeons make small incisions and use a camera and specialized instruments to remove a large portion of the stomach. This approach usually means:
- Less pain after surgery
- Reduced scarring
- Shorter hospital stays (often 1–2 days)
- Faster recovery times
2. The Stomach Is Permanently Reshaped
During surgery, about 75–80% of the stomach is removed, leaving behind a narrow, tube-like “sleeve.” This is a permanent procedure, unlike adjustable gastric banding, which can be reversed. Patients feel full faster, eat less, and gradually lose weight as a result.
3. It Changes Hormone Production
Sleeve gastrectomy does more than just reduce stomach size. The surgery also removes the portion of the stomach that produces ghrelin, the “hunger hormone.” By lowering ghrelin levels, many patients experience reduced appetite and fewer cravings, making it easier to maintain healthier eating habits.
4. High Success Rates
Sleeve gastrectomy has proven to be highly effective. According to the American Society for Metabolic and Bariatric Surgery (ASMBS), most patients lose 50–60% of their excess body weight within 12–18 months of surgery. Beyond weight loss, many patients also experience significant improvements in obesity-related conditions such as type 2 diabetes, sleep apnea, and high blood pressure.
5. Benefits Over Gastric Bypass
Both sleeve gastrectomy and gastric bypass are effective, but sleeve surgery offers certain advantages for some patients:
- Simpler anatomy: No rerouting of the intestines is required.
- Lower risk of nutrient deficiencies compared to gastric bypass.
- Shorter operative time and fewer potential long-term complications.
That said, the best procedure depends on individual health needs and goals, which is why consultation with an experienced bariatric surgeon is essential.
6. Lifestyle Changes Are Key
Sleeve gastrectomy is a powerful tool, but it works best when combined with long-term lifestyle changes. Patients need to commit to:
- Eating smaller, nutrient-rich meals
- Staying hydrated throughout the day
- Exercising regularly
- Following follow-up appointments and support programs
With dedication, patients can enjoy long-lasting results and improved overall health.
7. It’s More Than Just Weight Loss
For many, sleeve gastrectomy is life-changing. Beyond the physical transformation, patients often report:
- Increased energy and mobility
- Greater self-confidence
- Improved quality of life
- Reduced risk of serious medical conditions
This is why sleeve gastrectomy has become one of the most widely performed weight loss surgeries worldwide.
