GLP-1 weight loss medications have transformed how we think about obesity treatment. If you've been hearing about Ozempic, Wegovy, Mounjaro, and Zepbound and wondering whether they might be right for you — here's what a San Jose surgeon who actually prescribes these medications wants you to know.
At Lifetime Surgical, we offer a complete spectrum of weight loss care — from GLP-1 medications to bariatric surgery — because there's no one-size-fits-all solution. Dr. Richard Nguyen and our medical team help San Jose and South Bay patients find the right path based on their unique health profile, goals, and lifestyle.
GLP-1 (glucagon-like peptide-1) receptor agonists are injectable medications that mimic a natural hormone your body produces after eating. They work by:
Ozempic (semaglutide 0.25mg–2mg) — Originally FDA-approved for type 2 diabetes. Widely prescribed off-label for weight loss. Weekly injection.
Wegovy (semaglutide 0.25mg–2.4mg) — FDA-approved specifically for chronic weight management. Clinical trials showed average weight loss of 15-17% of body weight.
At Lifetime Surgical, we prescribe semaglutide as part of our comprehensive medical weight loss program.
Mounjaro (tirzepatide 2.5mg–15mg) — Originally FDA-approved for type 2 diabetes. Dual-action: works on both GLP-1 AND GIP receptors.
Zepbound (tirzepatide 2.5mg–15mg) — FDA-approved specifically for chronic weight management. Clinical trials showed average weight loss of 20-25% of body weight — the most effective weight loss medication available.
Lifetime Surgical offers tirzepatide for patients who may benefit from this dual-action approach.

Most side effects are gastrointestinal and tend to improve over time:
We offer both medical AND surgical weight loss. If GLP-1 medications aren't enough, we can seamlessly transition to bariatric surgery — no starting over with a new provider.
GLP-1 medications can occasionally cause gallbladder problems. If you need your gallbladder removed, Dr. Nguyen can perform laparoscopic cholecystectomy — something a telehealth provider cannot offer.
Dr. Nguyen has managed thousands of patients through weight loss journeys. He understands the physiology of weight loss at a depth that most non-surgical providers cannot match.
Having a practice that supports you at every stage provides continuity that telehealth apps cannot.
For patients who need significant weight loss, both options are effective but work differently. GLP-1 medications produce 15-25% body weight loss; bariatric surgery produces 50-70% excess weight loss. GLP-1 requires ongoing medication; surgery provides permanent anatomical change.

How quickly will I lose weight on Ozempic or Mounjaro?
Most patients notice appetite changes within 1-2 weeks. Measurable weight loss typically begins within the first month. The most significant loss occurs during months 4-12.
What happens if I stop taking the medication?
Research shows most patients regain significant weight within 1-2 years of stopping. This is why ongoing supervision and lifestyle changes are important — and why some patients eventually consider bariatric surgery.
Can I take GLP-1 medications after bariatric surgery?
In some cases, yes — for patients who experienced weight regain after surgery. Dr. Nguyen can discuss whether this combination approach is right for you.
Are compounded semaglutide or tirzepatide safe?
The FDA has issued warnings about compounded versions. At Lifetime Surgical, we prescribe only FDA-approved, brand-name medications.
