If you've been hearing about Ozempic, Wegovy, Mounjaro, and Zepbound — the GLP-1 medications that have transformed weight loss medicine — you're not alone. These medications are making headlines for a reason: they work. But there's a significant difference between getting a prescription from an online service and receiving physician-supervised medical weight loss from a doctor who actually understands obesity.
At Lifetime Surgical in San Jose and Los Gatos, Dr. Richard Nguyen offers a comprehensive medical weight loss program featuring both semaglutide and tirzepatide — backed by real medical evaluation, lab work, and ongoing clinical oversight.
Semaglutide is a GLP-1 receptor agonist — a medication that mimics a hormone your body naturally produces after eating. It works by reducing appetite, increasing feelings of fullness, and slowing how quickly food leaves your stomach.
Clinical results: In large-scale trials, patients on semaglutide lost an average of 15-17% of their total body weight. For someone weighing 250 pounds, that's 37-42 pounds. Semaglutide was the first GLP-1 to receive FDA approval specifically for chronic weight management.
Tirzepatide is the newest and most powerful weight loss medication available. Unlike semaglutide, which acts on one receptor, tirzepatide is a dual GIP/GLP-1 receptor agonist — working on two hormonal pathways simultaneously.
Clinical results: In head-to-head studies, tirzepatide produced greater weight loss than semaglutide. Patients lost an average of 20-25% of their total body weight. For a 250-pound person, that's 50-62 pounds — results that were previously only achievable through surgery.
Let's be direct. You can get semaglutide or tirzepatide from dozens of telehealth services, med spas, and online platforms across San Jose. So why come to a surgical practice?
Online services often prescribe based on a questionnaire. At Lifetime Surgical, you receive a comprehensive in-person medical evaluation. Dr. Nguyen examines you, reviews your complete health history, and orders appropriate baseline lab work — metabolic panel, thyroid function, HbA1c, lipid panel, and more. This isn't just about weight loss. It's about making sure you're safe and that GLP-1 therapy is the right approach.
GLP-1 medications require careful titration — gradually increasing the dose over weeks to months. Without proper monitoring, patients can experience significant side effects, nutritional deficiencies, or muscle loss. Our program includes regular follow-up visits, repeat lab work, and dosage adjustments based on your individual response.
This is the biggest differentiator. Most online services can only prescribe medication. If medication alone doesn't achieve your goals — or if your BMI and health conditions indicate that surgery would deliver dramatically better outcomes — we offer the full spectrum of weight loss solutions under one roof. Dr. Nguyen can objectively guide you to the right path, whether that's:
Dr. Nguyen has spent 20+ years treating obesity surgically and medically. He understands the physiology, the metabolic implications, and the long-term management strategies that a telehealth service simply cannot provide. You're not a subscription — you're a patient.

You may be a good candidate if:
How much weight will I lose?
Individual results vary. On average, semaglutide patients lose 15-17% of body weight and tirzepatide patients lose 20-25%. Some patients lose more, some less. Factors include starting weight, adherence to nutritional recommendations, activity level, and individual response to medication.
What are the side effects?
The most common side effects are gastrointestinal — nausea, decreased appetite, and occasional constipation or diarrhea. These are typically mild, occur mainly during dose increases, and usually improve as your body adjusts. Our careful titration schedule is designed to minimize these effects.
How long do I need to take it?
This is an important conversation to have with your physician. Some patients use GLP-1 medications for 12-18 months, reach their goal, and successfully transition off with lifestyle habits. Others benefit from longer-term use. Dr. Nguyen will discuss a realistic long-term strategy during your consultation.
Does insurance cover it?
Coverage varies by plan. Some insurers cover Wegovy and Zepbound for weight management; others require prior authorization or don't cover weight loss indications. Our team can help you navigate your coverage options.
Whether you're just starting to explore weight loss options or you've been researching GLP-1 medications for months, the next step is simple: schedule a consultation. Dr. Nguyen will evaluate your health, discuss your goals, and help you decide if semaglutide, tirzepatide, surgery, or another approach is the right fit.
