If you've been struggling with your weight despite years of dieting, exercise programs, and willpower — you're not failing. Obesity is a medical condition, not a character flaw, and sometimes the most effective treatment is surgical.
At Lifetime Surgical in San Jose and Los Gatos, Dr. Richard Nguyen has performed over 5,000 weight loss surgeries using the most advanced robotic and laparoscopic techniques available. This guide covers everything you need to know about bariatric surgery options in San Jose.
The gastric sleeve is the most commonly performed bariatric procedure in the United States today — and for good reason. During this procedure, approximately 75-80% of the stomach is removed, creating a smaller sleeve-shaped stomach that naturally limits food intake and dramatically reduces hunger hormones.
What to expect:
Dr. Nguyen performs gastric sleeve surgery using the da Vinci Robotic Surgical System, providing enhanced precision through small incisions — typically just 4-5 tiny incisions that heal to nearly invisible marks.
Gastric bypass remains the gold standard for patients with higher BMIs, significant metabolic disease, or severe acid reflux (GERD). This procedure creates a small stomach pouch and reroutes a portion of the small intestine.
What to expect:
Had a previous weight loss surgery that didn't deliver the results you expected? Experienced weight regain? Dealing with complications from a procedure performed elsewhere? Dr. Nguyen specializes in complex revisional bariatric surgery — some of the most technically demanding procedures in the field.

Not everyone needs surgery to achieve meaningful weight loss. Lifetime Surgical also offers a comprehensive medical weight loss program featuring FDA-approved GLP-1 medications including semaglutide (Wegovy/Ozempic) and tirzepatide (Mounjaro/Zepbound).
These medications can produce 15-25% total body weight loss under physician supervision. Dr. Nguyen can help determine whether a medical or surgical approach — or a combination — is right for your situation.
The South Bay has several bariatric surgeons. Here's what sets Lifetime Surgical apart:
