GLP-1 Weight Loss in San Antonio — Semaglutide & Tirzepatide at THEIA
Medically supervised semaglutide and tirzepatide programs — longitudinal medical weight-loss care in Stone Oak.
About GLP-1 & Semaglutide
Considered care, calibrated to you.
GLP-1 weight loss in San Antonio — semaglutide and tirzepatide — is the medical breakthrough behind the current generation of weight-loss therapies. These GLP-1 (and GLP-1/GIP) receptor agonists regulate appetite signals in the brain, slow gastric emptying and improve insulin sensitivity, which together produce steady, sustained weight loss when paired with medical supervision, nutrition guidance and consistent lifestyle habits. At THEIA in Stone Oak, our medical weight loss program in San Antonio is medically supervised from first evaluation through titration and maintenance. Every patient undergoes a complete medical intake — labs when indicated, medication review, BMI and comorbidity assessment — before we prescribe. Dosing is titrated gradually to minimize gastrointestinal side effects, and we follow up regularly to adjust dose, review progress and monitor for tolerability. This is not a 'weight-loss shot at a med spa' — it is longitudinal medical care in a discreet, medically directed setting, serving Stone Oak, Sonterra, Hollywood Park and greater North San Antonio.

GLP-1 weight loss treatment at THEIA is prescribed under the medical direction of a Texas-licensed physician. A complete medical evaluation is required prior to prescription. GLP-1 medications are not appropriate for every patient; contraindications include personal or family history of medullary thyroid carcinoma or MEN 2, pregnancy, and certain other conditions — screened at consultation. Individual results vary.
Questions
Frequently asked.
Do you offer GLP-1 (GLP1) weight loss in San Antonio?
Yes. THEIA is a medically directed medical weight loss clinic in San Antonio offering GLP-1 therapy — semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) — from our Stone Oak location at 238 N Loop 1604 W, Suite 206. Every GLP1 prescription follows a medical evaluation with our Medical Director.
How much does semaglutide cost in San Antonio?
Our program is a bundled monthly medical plan that includes the medication, clinical visits, titration monitoring and follow-up. We publish transparent pricing at consultation with no hidden fees. Costs vary based on medication (semaglutide vs tirzepatide) and dose. FSA/HSA may apply — bring documentation to consultation.
Semaglutide vs tirzepatide (Wegovy vs Zepbound / Ozempic vs Mounjaro) — which is better?
Both are highly effective. Tirzepatide (a dual GLP-1/GIP agonist) shows slightly higher average weight loss in clinical trials but at higher cost. Semaglutide has longer real-world safety data. The right choice depends on your medical history, insurance/coverage situation, tolerability and goals — determined at your complimentary consultation with our Medical Director.
How much weight will I lose?
Clinical trials show average weight loss of 15% of body weight over 68 weeks with semaglutide, and up to 20% with tirzepatide — when paired with lifestyle changes. Individual results vary. Our program emphasizes sustainable pace over aggressive targets.
What are the side effects?
The most common are gastrointestinal: nausea, mild indigestion, constipation, or loose stools — usually mild and transient during dose increases. Our titration protocol is designed to minimize these. Rare but serious risks (pancreatitis, gallbladder issues, thyroid concerns) are discussed at consultation and monitored throughout your care.
Do I need to change my diet and exercise?
Yes. GLP-1s are most effective — and most sustainable — when paired with protein-forward nutrition and consistent movement. We provide practical guidance, not restrictive plans. Muscle preservation is a priority; strength training is strongly encouraged.
What happens if I stop the medication?
Weight regain is common when GLP-1s are stopped without a lifestyle plan in place. That's why our program builds nutrition and movement habits alongside the medication, and why maintenance dosing (lower dose, longer intervals) is often part of long-term care.
Is semaglutide safe? Is it FDA-approved?
Semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) are FDA-approved. Wegovy and Zepbound carry specific FDA indications for chronic weight management. Our program prescribes them within FDA-approved and evidence-based clinical use, under medical supervision.
Who supervises the program at THEIA?
Our Texas-licensed Medical Director reviews every intake, authorizes every prescription and oversees titration. Clinical and support staff assist with visits, monitoring and follow-up under written delegation, but every medical decision rests with the Medical Director.
Can I combine GLP-1 with body contouring or Body Tone?
Many patients pair GLP-1 with body shaping, Lipolaser and Body Tone once they approach their goal weight, to address remaining stubborn fat and preserve/build muscle. We sequence these treatments in a medically supervised plan.
