Medical Weight Loss in San Antonio — Medically Directed Programs at THEIA
Medically directed weight loss with labs, root-cause assessment and monitored medication when indicated.
About Medical Weight Loss
Considered care, calibrated to you.
Medical weight loss in San Antonio means treating body weight as a clinical condition with measurable inputs — metabolic labs, medication history, body composition, sleep, stress and thyroid function — rather than as a discipline problem. At THEIA in Stone Oak, the program begins with a medical consultation under our Medical Director and a diagnostic workup, not with a prescription. Some patients turn out to be excellent candidates for GLP-1 therapy; others have an untreated thyroid issue, an insulin-resistance pattern, a medication that is driving weight gain, or a sleep disorder that no injection will fix. Identifying which of those applies to you is the entire point of a medical program. From there we build a plan that may combine medically prescribed medication, protein-forward nutrition targets, resistance-training guidance, and body-composition tracking so you can see whether you are losing fat or losing muscle — a distinction the bathroom scale cannot make. Follow-up is scheduled, not optional, because the difference between a program that works and one that stalls is almost always the cadence of adjustment. We serve Stone Oak, Sonterra, Hollywood Park, Alamo Heights and greater North San Antonio.

Ideal candidates.
- —Adults who have lost and regained weight repeatedly through diet and exercise alone
- —Patients with BMI ≥ 30, or BMI ≥ 27 with comorbidities such as hypertension, sleep apnea or prediabetes
- —Patients who suspect a metabolic, hormonal or medication-related cause of weight gain

Questions
Frequently asked.
What is a medical weight loss clinic, and how is it different from a diet program?
A medical weight loss clinic evaluates and treats weight as a clinical condition — with a medical exam, diagnostic labs, prescription therapy when indicated, and scheduled monitoring. A diet or coaching program offers guidance but cannot order labs, diagnose an underlying cause, or prescribe medication.
Do I have to take a GLP-1 to join the program?
No. Medication is one tool, prescribed when it is medically appropriate. Some patients begin with treating an underlying thyroid or insulin-resistance issue and a structured nutrition plan, and never need an injection.
How much does medical weight loss cost in San Antonio?
Cost depends on whether medication is part of your plan. Programs without prescription therapy are considerably less expensive than GLP-1 programs, which bundle medication with clinical visits and monitoring. Transparent pricing is given at consultation with no hidden fees, and FSA/HSA may apply.
Does insurance cover medical weight loss in Texas?
Coverage is inconsistent. Some commercial plans cover office visits and labs, and a smaller number cover brand-name GLP-1 medication for documented indications with prior authorization. We can provide documentation for you to submit, and we discuss self-pay options openly.
How much weight can I expect to lose?
It depends on your starting point, your plan and whether medication is included. Medically supervised programs commonly target 5 to 10% of body weight in the first six months without medication, and substantially more with GLP-1 therapy. Individual results vary and no specific outcome is promised.
Do you offer telemedicine visits?
Follow-up visits can often be conducted by telemedicine for established patients. The initial consultation and good faith examination follow Texas requirements and are arranged at scheduling.
What if I have already tried semaglutide elsewhere?
That history is useful, not disqualifying. Bring your prior dosing, duration and side-effect experience — it directly informs whether we resume, switch molecules, or address something the previous program did not evaluate.
Can I combine weight loss with body contouring?
Yes, and sequencing matters. Contouring and muscle-toning treatments are most effective once weight has stabilized near goal, which is why we plan them as a later phase rather than running them in parallel.
