At Clínica MEDS, care conditions and values may vary depending on the agreement.
What is the difference between a sleeve and a gastric bypass?
Both surgeries help treat obesity and can improve metabolic conditions, but they work differently.
A sleeve gastrectomy makes the stomach smaller, limiting how much food you can eat.
A gastric bypass makes the stomach smaller and changes the path food takes through the digestive system, so it combines restrictive and metabolic mechanisms.
The choice depends on your history, your health needs and the medical evaluation. There is no ideal surgery for everyone.
How do I know if I am a candidate for bariatric surgery?
The indication depends on an individual medical evaluation. Your BMI, associated conditions, health history, previous treatments and the possible benefits and risks of surgery are considered.
As a reference, the criteria considered include:
- A BMI of 40 or higher.
- A BMI between 30 and under 35, in patients with obesity-related conditions and hard-to-manage metabolic changes.
The evaluation determines whether surgery is a suitable alternative for you and which one could offer you the greatest benefit.
