Lasting weight loss isn't about willpower — it's about the right medical plan, monitored by a physician who knows your full health picture.
Oasis Medical Group offers physician-supervised medical weight loss for adults in North County San Diego who want a real, sustainable plan — not a generic diet or an unsupervised prescription. Every patient starts with a full evaluation of their health history, current medications, and weight loss goals before any treatment plan is built. From there, care is monitored and adjusted over time, not handed off after the first visit.
This isn't a quick-fix program. It's ongoing medical care, designed around what's safe and effective for your body specifically.
Sustainable weight loss requires more than willpower. At Oasis Medical Group, Dr. Kareem Moasis, MD, and his team treat excess weight as a medical issue — evaluating hormones, metabolism, lifestyle, and your full health picture before recommending a plan.
Our medical weight loss program uses FDA-approved GLP-1 medications such as tirzepatide and semaglutide when clinically appropriate, combined with nutrition guidance, body composition tracking, and ongoing physician follow-up.
Physician-supervised GLP-1 weight management with monthly follow-ups, nutrition coaching, and body composition tracking — choose the plan that fits your goals.

Weight loss medications and plans aren't one-size-fits-all, and they're not risk-free when unsupervised. A physician-led program means your plan accounts for your full medical history, gets adjusted based on how your body actually responds, and includes real follow-up — not just an initial prescription and silence.
Step 1
A comprehensive review of your health history, current weight, goals, and any factors — medications, conditions, prior weight loss attempts — that affect what approach makes sense for you.
Step 2
Your plan is built around your evaluation — not a standard protocol applied to every patient. When appropriate, that includes FDA-approved GLP-1 medications (tirzepatide or semaglutide), nutrition coaching, and metabolic monitoring.
Step 3
Regular follow-up visits to track progress, adjust your plan as needed, and monitor for side effects — medical supervision, not a set-it-and-forget-it prescription.
Step 4
Weight loss that lasts requires a plan built for the long term. Your care continues to be adjusted as your body and goals change.

When appropriate, that includes FDA-approved GLP-1 medications such as tirzepatide and semaglutide, which help regulate appetite and blood sugar while you work on nutrition, movement, and lifestyle changes with medical support at every step.
It is structured, monitored care — with dose adjustments, side-effect management, and progress tracking built into your membership. You are not left to manage injections or dosing on your own without physician oversight.
Medical weight loss is for adults who want safe, sustainable results — especially when weight is affecting their health, energy, or quality of life and diet alone has not been enough. It is designed to help with:
