For many people struggling with severe obesity, diet plans and exercise alone may not provide lasting results.
When excess weight begins affecting health, doctors may recommend bariatric surgery.
But patients often ask:
What exactly is bariatric surgery, who is eligible, and how much weight can you realistically lose? This guide explains everything in simple terms.
Considering weight loss surgery? Ask RUA to understand eligibility, hospital options, and expected results.
What Is Bariatric Surgery?
Bariatric surgery refers to medical procedures that help people lose weight by changing how the digestive system works.
The surgery helps by:
- Reducing stomach size
- Limiting food intake
- Reducing calorie absorption
- Controlling hunger hormones
It is not cosmetic surgery it is a medical treatment for obesity and related diseases.
Types of Bariatric Surgery
1. Gastric Sleeve Surgery (Sleeve Gastrectomy)
- Removes a portion of the stomach
- Smaller stomach = less food intake
- Most commonly performed procedure today
2. Gastric Bypass Surgery
- Creates a small stomach pouch
- Food bypasses part of the intestine
- Helps both weight loss and diabetes control
3. Mini Gastric Bypass
- Simplified bypass procedure
- Faster surgery and recovery in selected patients
- Your surgeon recommends the best option based on your health condition and BMI.
Who Is Eligible for Bariatric Surgery?
Doctors usually recommend surgery if:
1. Body Mass Index (BMI) above 40
2. BMI above 35 with health problems such as:
- Type 2 diabetes
- High blood pressure
- Sleep apnea
- Joint problems
- Fatty liver disease
Patients should also:
- Have tried weight loss methods earlier
- Be medically fit for surgery
- Commit to lifestyle changes after surgery
Expected Weight Loss Outcomes

Average results:
- 60–80% excess weight loss within 12–18 months

Many patients experience significant improvement in overall quality of life.
