Types of Bariatric Surgery: Which One Is Right for Me?

For many people, weight loss is more than a number on the scale — it’s about reclaiming health, confidence, and quality of life. 
When lifestyle changes and diets aren’t enough, bariatric surgery can become a life-changing option. But with different types of procedures available, patients often ask: “Which surgery is right for me?”

At Medilik, we guide international patients and locals in Istanbul through every step of their bariatric journey, helping them choose the procedure best suited for their body and lifestyle. Let’s explore the most common types of bariatric surgery and how to know which might be the right fit for you.

One of the most popular bariatric surgeries worldwide, the gastric sleeve involves removing about 70–80% of the stomach. 
This leaves a smaller, sleeve-shaped stomach that limits how much food you can eat while also reducing hunger hormones.

Best for: Patients with a BMI over 35 or those with obesity-related health issues.

Effectiveness: On average, patients lose 60–70% of their excess weight within 1–2 years.

Recovery: Hospital stay is typically 2–3 days with a few weeks of gradual recovery.

Why patients choose it: It’s done via a laparoscope not an open surgery, doesn’t involve rerouting the intestines, and offers excellent long-term results.

The gastric bypass has been considered the “gold standard” of bariatric surgery for decades. It works by creating a small stomach pouch and rerouting a section of the intestines, which reduces both food intake and nutrient absorption.

Best for: Patients with higher BMIs, severe reflux disease, or those who need faster weight loss.

Effectiveness: Patients typically lose 65–80% of excess weight.

Recovery: Hospital stay of 3–4 days, with gradual return to daily activities.

Why patients choose it: Effective for long-term weight loss and improving obesity-related conditions like type 2 diabetes.

A newer variation, the mini gastric bypass offers similar results to the traditional bypass but with a simpler surgical process. It involves creating a narrow stomach tube and connecting it to the intestine in a single loop.

Best for: Patients looking for strong results with a shorter operation time.

Effectiveness: Weight loss results are comparable to the standard bypass, often 65–75% of excess weight.

Recovery: Hospital stay is slightly shorter, usually 2–3 days.

Why patients choose it: Less complex surgery, effective outcomes, and lower risk of complications.

For patients who may not qualify or are not ready for surgery, the gastric balloon is a non-surgical alternative. A soft balloon is placed in the stomach via endoscopy and filled with saline, creating a feeling of fullness.

Best for: Patients with lower BMIs (27–35) or those wanting a temporary solution.

Effectiveness: Typically helps patients lose 10–20% of their body weight over 6–12 months.

Recovery: Same-day procedure with quick return to normal life.

Why patients choose it: No surgery, no incisions, and it can be removed at any time. 
 

Every patient is unique, and the right procedure depends on several factors:

• BMI and weight-related conditions (such as diabetes, hypertension, or sleep apnea).

• Lifestyle and eating habits — some surgeries work better for people who struggle with portion control, others for those with sweet cravings.

• Medical history — including previous abdominal surgeries, reflux, or other health conditions.

• Personal goals — whether you’re seeking dramatic weight loss, a non-surgical option, or improved overall health.
