Weight loss surgery—also known as bariatric surgery—is not just a medical procedure; for many, it’s the gateway to a healthier and longer life. With obesity rates climbing across the globe, particularly in developed countries like the United States, an increasing number of people are turning to surgery as a last resort. But not everyone qualifies.
What is Weight Loss Surgery?
Weight loss surgery or bariatric surgery refers to a group of surgical procedures aimed at helping individuals lose weight by modifying their digestive systems. These surgeries typically reduce stomach size or reroute parts of the digestive tract to help limit food intake or nutrient absorption.
The most common types include:
- Gastric Bypass (Roux-en-Y)
- Sleeve Gastrectomy
- Adjustable Gastric Band
- Biliopancreatic Diversion with Duodenal Switch
For detailed visuals and surgical descriptions, see the Mayo Clinic’s guide.
Medical Eligibility Criteria for Bariatric Surgery
The first step in determining if you’re eligible is checking whether you meet certain health and lifestyle conditions. Let’s break them down.
1. Body Mass Index (BMI)
Your BMI is one of the most critical factors in determining your eligibility.
| BMI Range | Qualification |
| 40 or higher | Automatic qualification |
| 35–39.9 | Qualifies with at least one obesity-related condition |
| 30–34.9 | May qualify in special medical cases |

2. Obesity-Related Health Conditions
You may qualify if you have one or more of the following:
- Type 2 diabetes
- Obstructive sleep apnea
- Hypertension
- Coronary artery disease
- Non-alcoholic fatty liver disease (NAFLD)

- Polycystic ovary syndrome (PCOS)
These conditions not only affect your quality of life but significantly increase your risk of stroke, heart attack, and early death.
3. Age Requirements
Most patients are between 18 to 65 years old. However, pediatric bariatric surgery is becoming more common in adolescents with severe obesity, and older patients are considered based on individual health status.

5. Lifestyle & Behavioral Assessment
Surgeons want to see that you:
