Body Mass Index is a key measure in medicine. It sorts people into weight groups like underweight, normal, overweight, and obese. In bariatric medicine, BMI is key to see how severe obesity is and the health risks it brings.
Standard BMI Thresholds for Gastric Bypass

- Normal weight: BMI = 18.5-24.9

FAQ
What is a bariatric surgery and how does it help with weight loss?
Bariatric surgery refers to medical procedures that help with significant weight loss by reducing stomach size, rerouting the digestive system, or both. This limits food intake and nutrient absorption, and can also alter hunger hormones, promoting long-term weight loss and improving obesity-related conditions.
What is the minimum BMI for gastric sleeve surgery?
Typically, the minimum BMI for gastric sleeve surgery is 35 kg/m² with obesity-related health conditions (like diabetes, hypertension) or 40 kg/m² without additional health issues. Exact criteria may vary depending on the medical facility and patient health status.
Can I qualify for surgery if my BMI for bariatric surgery is under 35?
In some cases, yes. Patients with a BMI between 30–35 kg/m² may qualify if they have serious obesity-related health conditions that could benefit from weight loss surgery, but this requires special evaluation by a bariatric surgeon.
What does the term bariatric mean in a medical context?
“Bariatric” relates to treatment and management of obesity. Bariatric medicine focuses on weight reduction, obesity prevention, and associated metabolic disorders.
What is the difference between a gastric bypass and a sleeve bypass surgery?
- Gastric bypass: Creates a small stomach pouch and reroutes the small intestine, reducing both food intake and nutrient absorption.
- Gastric sleeve (sleeve gastrectomy): Removes a portion of the stomach, reducing stomach size but keeping the digestive pathway normal. It primarily limits food intake and affects hormones related to hunger.

- Review your BMI and medical history
