Which weight-loss procedure is right for you?
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.
