This guide covers everything about gastric sleeve vs gastric bypass. Gastric sleeve (VSG) removes 75-80% of the stomach, while gastric bypass (Roux-en-Y) creates a small pouch and reroutes the intestine. Gastric sleeve is simpler, has fewer complications, and costs less ($3,898 vs $5,499 at Lighter Dream in Tijuana). Gastric bypass produces slightly more weight loss (70-80% vs 60-70% of excess weight) and is better for patients with severe acid reflux or type 2 diabetes.
Choosing between gastric sleeve and gastric bypass is one of the biggest decisions on your weight loss journey. In this guide, our bariatric surgeons in Tijuana break down every difference.

How Does Gastric Sleeve Surgery Work?
Gastric sleeve surgery (VSG) is a minimally invasive procedure where your surgeon removes approximately 75-80% of the stomach, leaving a banana-shaped “sleeve.” This dramatically reduces food intake and removes the ghrelin-producing portion, significantly reducing appetite.
At Lighter Dream in Tijuana, gastric sleeve takes 45-60 minutes, requires 1-2 nights in our accredited hospital, and costs $3,898 all-inclusive.
How Does Gastric Bypass Surgery Work?
Gastric bypass (Roux-en-Y) creates a small stomach pouch and reroutes the small intestine. It works through restriction, malabsorption, and hormonal changes — making it particularly effective for type 2 diabetes. At Lighter Dream, gastric bypass starts at $5,499.

What Dr. Jeffry Recommends
“For the majority of patients, gastric sleeve is the ideal first choice. It’s simpler, fewer complications, and excellent results. For severe diabetes, significant reflux, or BMI over 50, gastric bypass is the better long-term solution.”
