What Is the Best Bariatric Surgery? Here's How to Choose

Choosing the best weight loss surgery can feel overwhelming—but it doesn’t have to be. The truth is, there’s no one-size-fits-all answer. The “best” bariatric surgery depends on your health, lifestyle, weight loss goals, and any medical conditions like diabetes or GERD.

At University of Chicago | AdventHealth LaGrange Hospital, Dr. Jihad Kudsi, Medical Director of Bariatric Surgery, helps patients in Naperville, Oak Brook, Downers Grove, and across Chicago’s western suburbs choose the safest and most effective option for their needs.

Top 3 Bariatric Surgeries – Compared

🔹 1. Sleeve Gastrectomy (VSG)

How it works:Removes ~80% of the stomach, reducing hunger and food intake.
Pros:

Shorter surgery and recovery
Fewer long-term complications
No intestine bypass
Cons:
Irreversible
Can worsen acid reflux (GERD)
- Best for:Patients seeking a simpler option with fewer risks and strong results.

Average excess weight loss: 60–70%
Diabetes remission: ~50–60%

🔹 2. Gastric Bypass (Roux-en-Y)

How it works:Creates a small stomach pouch and reroutes the small intestine to change digestion and hormones.
Pros:

Stronger effect on diabetes
Helps with acid reflux
Cons:
More complex surgery
Risk of dumping syndrome
- Best for:Patients with diabetes, GERD, or who need more metabolic impact.

Average excess weight loss: 65–75%
Diabetes remission: ~60–80%

🔹 3. SIPS / SADI-S (Single Anastomosis Duodeno-Ileal Bypass)

How it works:A sleeve is combined with a simplified intestinal bypass, sparing the pylorus.
Pros:

Highest weight loss and diabetes remission
Lower risk of dumping syndrome than bypass
Cons:

Less widely available
Requires more nutrition follow-up
- Best for:Patients with severe obesity, poorly controlled diabetes, or prior sleeve failure.

Average excess weight loss: 70–85%
Diabetes remission: ~80–90%
