Obesity surgery
Which weight-loss procedure is right for you?
Medically reviewed by Dr. Ayşe Demir
Quick answer
There is no single best weight-loss procedure: the sleeve suits most first-time patients, the bypass may suit reflux or higher-BMI cases, and the balloon is a temporary non-surgical option. A surgeon confirms the right fit after screening your health and history.
- There's no single best option — the right one depends on your BMI, health conditions, goals and preferences.
- Sleeve: simple and very common. Bypass: may help severe reflux and diabetes. Balloon: non-surgical and temporary.
- A qualified surgeon decides with you after a proper screening — never a chart alone.
- Whichever you choose, long-term habits and aftercare matter most.
In this guide
Almost everyone who asks us about weight-loss surgery opens with the same question: which one, and how do you even choose? The reassuring part is that you don't choose on your own. What follows is a straight, no-spin walk through the main options, so that by the time you sit down for a consultation you already know what to ask.
The main options
- Gastric sleeve: removes part of the stomach. Simple, single-step, and the most common procedure worldwide.
- Gastric bypass: small pouch plus intestinal reroute. Often preferred for severe reflux or type 2 diabetes.
- Gastric balloon: a non-surgical, temporary balloon in the stomach. Reversible; suits some people who want to avoid surgery.

How the decision is made
It happens in order. You fill out a private screening inside the app, a qualified team goes through it, and then you speak with your surgeon directly. From there the two of you look at the trade-offs and settle on a plan, with everything on the table and nobody pushing you. The final call is a medical one, and it always sits with a person rather than a form.

How do I know which weight-loss procedure is right for me?
The right procedure depends on your BMI, health conditions (such as reflux or diabetes), goals and preferences. A qualified surgeon reviews all of this after a screening and recommends the best option for you — it is never decided by a chart alone.
Is the sleeve, bypass or balloon best?
There is no single best option. The sleeve is simple and very common, the bypass may help severe reflux and diabetes, and the balloon is a non-surgical, temporary option. A surgeon matches the choice to your situation.
