What is a medspa GLP-1 program in Illinois?
A medspa GLP-1 program is a prescription weight loss service that a medical spa adds to its treatment menu, typically featuring compounded semaglutide or tirzepatide prescribed through telehealth. For medspas in Illinois, the program runs under your existing brand: clients complete an online intake, meet with a provider licensed in Illinois by video, and receive medication from an FDA-registered 503A or 503B pharmacy if it is clinically appropriate. Telehealth Grow supplies the provider network, pharmacy connections, consent templates, EMR and subscription billing, so your team does not need to hire a medical director solely for weight loss. The result is a recurring monthly revenue line that pairs naturally with body contouring, skin tightening and wellness treatments you already offer.
Why Illinois is a strong market for a medspa GLP-1 program
Illinois has an estimated 12,719,141 residents (U.S. Census Bureau, 2025), ranking 6th among the 50 states and D.C., and its population has declined 0.7% since the 2020 Census.
Demand is concentrated in Chicago (2.7M), Aurora (182K), Naperville (153K) and Joliet (152K), but a telehealth model lets one brand serve patients statewide — including smaller towns and rural counties where in-person weight loss clinics are scarce.
The capital, Springfield, and the rest of the state run primarily on Central Time, so patient support and provider availability can be scheduled around local business hours.
CDC BRFSS data (2020) put Illinois’s adult obesity rate at 31.1%, close to the 31.3% median across U.S. states. Using that rate for the state’s roughly 9,920,900 adults gives an estimated 3,085,400 adults living with obesity — the core audience for provider-led GLP-1 care.
In CDC data the Midwest sits with the South at the top of U.S. regional obesity prevalence, which means sustained, year-round demand for medically supervised weight loss.
That is the opportunity for medspas and aesthetic practices in Illinois: a large, recurring need that a branded, compliant medspa GLP-1 program can serve without opening a traditional medical practice.

Illinois telehealth rules to know before you launch
The American Association of Nurse Practitioners (AANP) classifies Illinois as a reduced practice state: nurse practitioners need a career-long collaborative agreement with a physician for at least one element of practice. A compliant GLP-1 program needs that collaboration built into the staffing model, which Telehealth Grow arranges through its physician network.
- Provider licensure: the prescribing clinician must be licensed in the state where the patient is located at the time of the visit — here, Illinois.
- Telehealth prescribing: semaglutide and tirzepatide are not DEA-controlled substances, so they can generally be prescribed after a valid telehealth consultation. Adding controlled medications such as phentermine brings extra Ryan Haight Act and DEA telemedicine requirements.
- Ownership structure: corporate practice of medicine rules limit who may own a medical practice and vary by state. The MSO-PC model separates the business you own from the clinical practice that delivers care.
- Compounded medications: must come from state-licensed 503A pharmacies or FDA-registered 503B outsourcing facilities, and FDA compounding policy shifts as drug-shortage status changes.
- Advertising: Google and Meta require LegitScript certification for many telehealth and pharmacy ads — we support the application.

Revenue potential in Illinois
Here is an illustrative projection. If a medspa GLP-1 program in Illinois reached just 0.05% of the adults estimated to be living with obesity, and each active patient generated about $120 in monthly profit (the benchmark used in our revenue calculator), the numbers would look like this:
| Adults living with obesity (est.) | 3,085,400 |
|---|---|
| Active patients at 0.05% reach | 1,543 |
| Estimated monthly profit | $185,160 |
| Estimated annual run rate | $2,221,920 |
Illustration only, not a guarantee. Actual revenue depends on medication costs, dosages, pricing, telehealth visit fees, marketing spend and patient retention.
