Sleeve gastrectomy is a weight-loss surgery that removes about 75-80% of the stomach, leaving a narrow, banana-shaped sleeve that limits food intake and reduces hunger hormones. It helps people with obesity lose significant weight and improve conditions like diabetes and high blood pressure. In this guide, we explain how the procedure works, its key benefits, possible risks, and the results you can realistically expect. We also cover recovery, diet changes, and how to decide if it's right for you. Read on to make an informed decision with the bariatric specialists at Lux Hospitals.
What Is Sleeve Gastrectomy?
Sleeve gastrectomy is a popular type of bariatric surgery used to treat obesity. The surgeon removes a large portion of the stomach, leaving a small tube-shaped pouch.
This smaller stomach holds less food and lowers the hunger hormone ghrelin. The result is reduced appetite and steady weight loss.
Key facts to know:
- Removes about 75-80% of the stomach
- Leaves a narrow, sleeve-shaped pouch
- Reduces hunger and food intake
- Usually done laparoscopically
- Permanent and non-reversible

How the Procedure Works
The operation is usually performed as a laparoscopic sleeve gastrectomy through small keyhole incisions. This means less pain and quicker recovery.
Surgery generally takes one to two hours under general anaesthesia. Most patients stay in hospital for two to three days.
Here is what typically happens:
- Small incisions in the abdomen
- Camera and instruments inserted
- Large part of stomach removed
- Remaining stomach stapled into sleeve
- Incisions closed and monitored

Key Benefits of Sleeve Gastrectomy
Sleeve gastrectomy offers more than weight loss. It can significantly improve overall health and quality of life.
Many patients see obesity-related conditions improve or resolve. It is also a valuable form of metabolic diabetic surgery for people with type 2 diabetes.
Common benefits include:
- Significant, lasting weight loss
- Improved or resolved type 2 diabetes
- Lower blood pressure and cholesterol
- Reduced sleep apnoea symptoms
- Better mobility and energy
- No implanted device or rerouting
Who Is a Good Candidate?
Not everyone qualifies for surgery. Doctors assess your weight, health, and past efforts to lose weight.
A thorough evaluation as part of the overall bariatric procedure helps confirm suitability.
You may be a candidate if you:
- Have a BMI of 40 or higher
- Have BMI 35+ with health conditions
- Struggled with diet and exercise
- Are committed to lifestyle changes
- Have no untreated eating disorders
Book a candidacy assessment with the bariatric team at Lux Hospitals.
Risks and Possible Complications
Like any major surgery, sleeve gastrectomy carries some risks. Most patients recover well, but complications can occur.
Some patients develop or worsen GERD acid reflux after surgery, which needs medical attention.
Potential risks include:
- Bleeding or infection
- Staple line leaks
- Blood clots
- Acid reflux or heartburn
- Nutritional deficiencies
- Nausea in early recovery
Expected Results and Weight Loss
Results vary, but most patients lose a substantial amount of weight within the first year. Sustained results depend on lifestyle habits.
Weight loss is usually gradual and steady over 12 to 18 months.
Typical expected results include:
- Loss of 50-60% excess weight
- Fastest loss in first 6 months
- Improved metabolic health
- Reduced medication needs
- Better long-term quality of life

Recovery and Diet After Surgery
Recovery involves gradual dietary changes and follow-up care. Your stomach needs time to heal.
You will progress through stages of eating, starting with liquids and slowly adding solids.
Key recovery steps include:
- Clear liquids in the first days
- Pureed foods after one to two weeks
- Soft foods, then regular meals
- Lifelong vitamin supplements
- Regular follow-up appointments
- Ongoing physical activity
How It Compares to Other Options
Sleeve gastrectomy is one of several weight-loss procedures. The right choice depends on your health and goals.
Your surgeon will explain the pros and cons of each option.
Common alternatives include:
- Gastric balloon — temporary, non-surgical
- Gastric banding — adjustable band device
- Mini gastric bypass — reroutes digestion
- Roux-en-Y gastric bypass — combined approach
