Functional Medicine for Oak Brook Residents

Feel like short appointments leave little room to understand what is really affecting your health? Our functional medicine care begins with a 90-minute initial visit, giving you dedicated time to discuss your health history, symptoms, medications, lifestyle, previous testing, and health goals. This detailed review helps identify patterns and possible factors contributing to how you feel, with in-depth laboratory testing used when appropriate for additional insight. For patients looking for a functional medicine practitioner in Oak Brook, this type of care can be useful when health concerns are persistent, complex, or difficult to manage.

Perimenopause Therapy Services

Perimenopause can begin in your 30s or 40s, sometimes bringing changes in periods, sleep, anxiety, energy, concentration, or body aches before you fully understand what is happening. For Oak Brook women experiencing perimenopause, our approach includes comprehensive hormone and metabolic testing to provide greater clarity and help shape a plan around those symptoms. Because the experience varies from one person to another, care is individualized, with conventional and more natural therapy options discussed alongside what current evidence supports.

Heavy or changing periods in perimenopause: Perimenopause may bring changes in when your period arrives, how long it lasts, and how heavy the bleeding is. While these changes can be part of the hormonal transition, unusually heavy or prolonged bleeding may require further evaluation. A review of your symptoms and testing can help determine whether additional assessment is needed, with specialist referral recommended when further investigation is appropriate.

Menopause Therapy Services

Hot flashes, poor sleep, brain fog, and mood changes can make menopause harder to manage, but they do not have to take over your day-to-day life. Our menopause therapy combines nutrition, lifestyle strategies, and bioidentical hormone therapy when appropriate, helping Oak Brook women address underlying hormone-related changes rather than symptoms alone. Care is available throughout premenopause, perimenopause, and menopause as hormone-related changes evolve.

Bioidentical Hormone Replacement Therapy (BHRT)

Hormone-related changes can affect women and men in different ways, influencing energy, sleep, mood, libido, weight, and overall well-being. Our individualized BHRT uses bioidentical hormones that are structurally identical to hormones produced naturally by the body. Comprehensive testing establishes a treatment baseline, while regular monitoring allows care to be adjusted based on laboratory results and symptoms over time. We’ve worked with the same trusted compounding pharmacies for 15 years to formulate therapy specific to your needs.

Other Health Concerns We Address

Alongside hormone care, we help Oak Brook patients address other persistent health concerns through a whole-body functional medicine approach. These include chronic fatigue, digestive problems, autoimmune concerns, thyroid dysfunction, sleep disturbances, mood-related symptoms, weight changes, and other ongoing health issues. When several health concerns are present at the same time, having them addressed within the same practice can make care more consistent and easier to manage. See the full list of conditions we treat for more details.

Experienced registered nurses provide treatments throughout our house-call service area.

Stem Cell Therapy

For Oak Brook patients experiencing joint pain, tendon or ligament injuries, or chronic degeneration, our stem cell therapy uses Wharton’s Jelly and purified amniotic fluid injections to support the body’s natural healing response. Depending on the situation, this treatment may be considered before surgery or alongside long-term steroid injections. Products come from FDA-inspected labs and are screened from healthy donors, while each treatment plan is tailored to the specific joint, injury, and individual goals.

Regenerative & Longevity Medicine

Our regenerative and longevity medicine services offer Oak Brook patients another way to take a proactive approach to healthy aging. The program includes peptide therapy, NAD+ IV nutrition, and other cellular-support treatments focused on supporting energy, vitality, and overall health span over time.

Membership-Based Options for Ongoing Care

For continued functional medicine support, membership provides a structured way to stay connected to care as follow-up visits, testing, prescriptions, and treatment adjustments become part of the process. Membership benefits include ongoing functional medicine visits, nutritional IV therapy, provider support, and discounts on additional services, with specific benefits varying by membership level. Individual services such as stem cell therapy, IV therapy, and ozone therapy are also available without a membership.

Masooda Rahman ★★★★★
I have been a client with Joya and what brought me to her was the way she looks at the body as a whole. I have never felt rushed by her or not validated. Recently I experienced back pain - which was a result of a slip disk at L4 and it was recommended by the doctor to get a steroid injection. This didn’t sit right with me- I talked to Joya and we decided to do a PRP shot. Within a few days my back stopped hurting and I was able to return to normal activities. Joya is also great when it comes to BHRT- … More she really listens and works with you to make sure you are getting the right dose. My experience thus far has succeeded anything I could have imagined

What truly sets Joya apart is her empathy and delicate approach. She’s incredibly gentle, ensuring that the IV is administered with the utmost care and precision. Throughout … More the process, she checks in frequently to make sure you’re feeling okay, and her attention to detail is unmatched.

I’ve worked with Joya for several years to help manage my chronic symptoms and have been able to get to a place, with her help, where I can handle things much better than when I started. Thank you, Joya, for everything!
Shannon Morrow ★★★★★
I cannot say enough good things about Joya! As a fellow medical provider it was a breath of fresh air to have thorough testing done AND even more thorough explanation of results and a reasonable plan to start fixing the problems to get to the point of feeling well again and to live a healthy and long life....but HEALTHY is key! I am so grateful to my patient that told me about Joya and I will continue to tell all of my patients why they need to see her and will quickly have my husband and daughter … More start seeing her as well! If you are tired of our "normal" medical field failing you then you need to take the next step and see a provider like Joya that really dives into the data and gets down to the "why" behind it all!! Thank you Joya...I am looking forward to the months to come and the journey I will be going on to a healthier version of myself as I am on this fun peri-menopause journey!!
Tamara Kiernan ★★★★★
Great experience! Joya is a fellow dedicated health enthusiast and extremely knowledgeable! She was able to help me dial in on what vitamins would work best for my needs. I highly recommend her and Nourish House Calls to everyone for your IV needs!
Dan Siebold ★★★★★
I came to Joya with a severe bulging L5S1 in my back. I had gone the route of traditional medicine for close to a year. Physical therapy, pain meds, steroid shots. All were temporary fixes and the debilitating pain just kept coming back. She recommended platelet rich plasma injections in the area around the disc to help the discs actually heal. Went through 3 rounds of this, the last of which was just a week ago. While the healing effects will continue to set in for at least the next 6 months, … More it is extremely evident this treatment is working. I can’t thank her enough and would highly recommend anyone who has experienced issues similar to mine give this treatment with nourish home house calls a chance.

Jill Longo ★★★★★
Can't say enough great things about Nourish House Calls. Joya takes the time to listen to you and understand what's going on and not just quickly prescribe something. I've been able to uncover issues such as a gluten intolerance and inflammation and that have been easy to resolve with changes to diet and exercise.

A serious problem I had has already stopped. I finally feel like I have the tools I need to heal. Thank you ♥️
Randy Crane ★★★★★
Joya is incredible!! I had just gotten over the flu and she recommended IV treatments. I felt better immediately and that night I slept better than I had in weeks. The process was painless and professional. Her staff was also very helpful.
Sabrina S ★★★★★
To say Joya saved my life, feels like an understatement. I felt horrendous when I came to see Joya. I had just finished my first 3 day water fast and severely malnourished and dehydrated. The level of education and kindness i experienced from Joya when she knew I have never done an IV drip before was wonderful and put me at ease. SHE WAS SO PATIENT WITH ME. I would do it again. I did the hydration package as well as NAD. By the end of the two bags, I felt back to normal. That's insane. Within … More hours!!! I am sooo incredibly thankful for you Joya. I learned so much for you and you made the experience enjoyable, and I felt better than ever!! When are you coming back to AZ? Also, for those reading, Joya was invited to a conference to do IV drips which is a gamechanger for people spending 3 days in a conference and tons of travel. Thank you Joya!!
Dave Erickson ★★★★★
Joya is so approachable and really wants to get to the root cause of any ailment. She is so detailed, smart, and kind in her approach with kids too. She listens well and cares in a holistic way. Highly recommend her!
Daniel Austin ★★★★★
Nourish House Calls is amazing! I just did my first vitamin drip with them and they were extremely knowledgable and super helpful. I would highly recommend giving them a try.
Stephanie ★★★★★
My functional doctor moved out of state and I needed to find a new provider that was trained in functional medicine, prescribes natural thyroid meds, and treats the whole body understanding it is all connected! Joya is like a walking encyclopedia when it comes to health. She is so easy to talk with and no ego like some doctors have when you ask questions. She does all kinds of gut testing, food sensitivity testing, hormone testing, etc. She also does vitamin IVs in her office, plus a lot of other … More treatments (Stem Cells, PRP, ozone).
HIGHLY RECOMMEND! She is a Functional Medicine Nurse Practitioner and so in Il can prescribe meds. She does house calls in some areas around Downers/Naperville area. I see her in her office in Downers Grove right on 63rd & Main Street. She also does Zoom visits. She provides me with a Superbill to send to insurance. You get her FULL attention for your time slot. She has membership options as well that come with a lot of her services and discounts. But you can also pay per visit.

Christy Goselin ★★★★★
I met Joya quite a few years ago, I had been seeing a doctor who had retired and my compounding pharmacy recommended her. She took right over, we met and I liked her immediately.
