Medical Weight Loss in King of Prussia, PA
A Physician-Led Program Built Around GLP-1 Medication
Medical weight loss at Lux Skin & Lasers starts with a consultation with Dr. Joseph Castelli, who reviews your health history, current medications, and past attempts at weight loss before building a plan around semaglutide or tirzepatide. Patients travel from King of Prussia, Bryn Mawr, and Margate for a program a physician actively manages, not a subscription that ships a pen to the door with no exam behind it.What You Gain With Dr. Castelli Managing Your Plan
A Plan Built Around Your History
Your program starts with the same intake Dr. Castelli uses across our locations: current medications, prior weight loss attempts, and conditions like sleep apnea or type 2 diabetes that shape which GLP-1 medication fits your case.
A Physician Reviews Every Dose Change
Semaglutide and tirzepatide are titrated upward over several weeks, and Dr. Castelli’s team reviews your response at each visit instead of leaving adjustments to an app or a call center.
Support Between Visits, Not Just at Them
Between appointments, our care team is the point of contact for side effect questions or a plateau, so a rough week doesn’t mean waiting a month for your next scheduled visit.
Medications the FDA Has Actually Approved
We prescribe semaglutide and tirzepatide, the two GLP-1 medications with full FDA approval for chronic weight management, dosed and monitored the way a prescription medication should be.
Fewer Weight-Related Health Risks
Patients managing type 2 diabetes, high blood pressure, or sleep apnea often see those numbers improve alongside the weight loss, and Dr. Castelli coordinates with your primary care physician when a medication change is involved.
What GLP-1 Weight Loss Does to Facial Volume
Losing weight quickly can thin the fat pads that keep a face looking full, a change patients now call “Ozempic face.” Dr. Lee built his practice around correcting that kind of volume loss, and his team addresses it with dermal fillers for patients whose GLP-1 program has reshaped their face along with their weight.

How Dr. Castelli Decides If GLP-1 Therapy Is Right for You
At our King of Prussia office, Dr. Castelli walks every new weight loss patient through the same four steps before anyone talks about a prescription.
Initial Consultation
You’ll go over your weight history, current medications, and what’s already failed to work at a sit-down visit with Dr. Castelli, not a phone screening.
Medical Evaluation
Bloodwork and a physical exam rule out thyroid issues or other conditions that can mimic weight resistance, and confirm that semaglutide or tirzepatide is safe for you to start.
Personalized Treatment Plan
Most patients start on either semaglutide treatment or tirzepatide treatment, dosed and titrated to your case, alongside the nutrition and activity guidance that helps keep the weight off once you reach maintenance.
Ongoing Support and Monitoring
Follow-up visits track your dose, side effects, and progress. Patients combining their program with body contouring often add CoolSculpting Elite once they’re close to goal weight, to address stubborn pockets that diet and medication alone won’t move.
Frequently Asked Questions About Medical Weight Loss in King of Prussia
Do I need to be off my diabetes or blood pressure medication to start semaglutide or tirzepatide?
No. Dr. Castelli reviews your current prescriptions at your evaluation and coordinates any adjustments with your primary care provider rather than asking you to stop treatment on your own.
How is this different from getting a GLP-1 prescription through a telehealth app?
Every visit, from your first evaluation to dose changes, happens in person with Dr. Castelli at our King of Prussia office, so adjustments are based on an exam and bloodwork rather than a questionnaire.
What if the starting dose doesn't work for me?
Semaglutide and tirzepatide are both titrated upward over several weeks. If side effects or slow progress come up at a follow-up visit, Dr. Castelli adjusts the dose or schedule instead of leaving you on the same plan.
Can I do CoolSculpting Elite or dermal fillers while I'm still losing weight?
Most patients wait until they’re within reach of goal weight, then add CoolSculpting Elite for stubborn areas or dermal fillers to address facial volume loss once the bulk of the weight is off.
