Oak Brook is one of DuPage County’s most recognizable communities — home to Oakbrook Center, the sprawling open-air shopping district off Route 83 and 22nd Street (Cermak Road), to a quiet grid of executive neighborhoods and corporate campuses, and to the former McDonald’s world headquarters that anchored the village from 1971 until the company moved to Chicago’s West Loop in 2018. It is also one of the easiest suburbs from which to reach a real, physician-supervised weight-loss clinic. ThinFast MD has provided medically based weight loss since 1984, and our Hinsdale clinic sits just south of Oak Brook, serving Oak Brook residents in person rather than by mail-order or telehealth alone.
Does ThinFast MD serve Oak Brook?
Yes. ThinFast MD does not operate a clinic inside Oak Brook itself — Oak Brook residents are served from our nearby Hinsdale clinic at 120 E. Ogden Ave, Suite 120, Hinsdale, IL. The drive is short and familiar: from central Oak Brook it is about 5 miles and roughly 10 to 15 minutes, typically Route 83 south to Ogden Avenue, or straight down Ogden. If you already make the run to Oakbrook Center or commute the I-88 and I-294 corridor, the Hinsdale office is an easy detour rather than a separate trip across the region.
Why see a physician in person instead of a mail-order program?
Plenty of online services will ship a GLP-1 pen after a brief questionnaire. ThinFast MD takes a different approach. Every Oak Brook patient is evaluated in person by our medical team under medical director Dr. Ehtesham Ghani, an Internal Medicine and Bariatric Medicine physician and a member of the American Society of Bariatric Physicians. That means a real exam, a review of your history and medications, and a plan built around how your body actually responds — not a one-size template. For a decision like prescription weight management, that supervision matters, and it is the part telehealth-only competitors skip.
What weight-loss options can Oak Brook residents get?
ThinFast MD offers a full range of physician-supervised tools, matched to your goals and health profile during your consultation. These include compounded and brand-name semaglutide (Wegovy and Ozempic), as well as tirzepatide (Zepbound and Mounjaro). In clinical trials, semaglutide produced average weight loss of roughly 15% in the STEP program, and tirzepatide roughly 15–21% in the SURMOUNT trials, when used alongside diet, exercise, and medical supervision — though individual results vary. Wegovy and Zepbound carry the weight-management approvals, while Ozempic and Mounjaro are approved for type 2 diabetes and used off-label for weight loss.
Beyond GLP-1 medications, we also offer phentermine and other appetite suppressants, OptitrimMD and OPTIFAST medically supervised meal replacement, lipotropic and B12 injections, an adolescent program, pre- and post-bariatric support, and one-on-one nutrition counseling. We frequently work with Oak Brook patients managing weight alongside related conditions such as PCOS, type 2 diabetes or prediabetes, thyroid disorders, and menopause-related weight gain.
How do I get started from Oak Brook?
The first step is a consultation at our Hinsdale clinic, where the team reviews your history, answers your questions, and recommends the approach that fits you. Pricing is reviewed individually at that consultation, since the right program depends on which services you choose. To book, call (708) 485-4050 or request a consultation online. From Oak Brook, you are only a short drive down Ogden Avenue from a weight-loss plan built and monitored by a physician.
