Functional Medicine
Functional medicine is for patients who are tired of being told everything looks normal while they still feel off. At Simply Health Integrated Medical, the goal is to connect the dots between symptoms, lab patterns, lifestyle, nutrition, hormones, digestion, metabolism, stress, and sleep so you can stop guessing and start building a clearer plan.
What to expect
Simply Health Integrated Medical helps patients understand symptoms, goals, and options before recommending a care path.
The next step is a consultation request or direct call so the team can determine whether the clinic is a good fit for your needs.

Functional medicine doctor near me in St. Louis: who you will see and what happens first
If you are searching for a functional medicine doctor near you in St. Louis, this is who you would see. Functional medicine at Simply Health Integrated Medical is led by Dr. Bryan Deloney, a Doctor of Chiropractic (DC) with a Master of Science in Human Nutrition and Functional Medicine. He is the clinic director, and he is the person who reviews your history, reads your labs, and builds the nutrition and lifestyle plan with you.
The clinic is in Creve Coeur at the I-64/I-270 interchange and sees patients from across St. Louis and west county. Your evaluation starts with your story and your symptoms; targeted labs are ordered when they will change the plan. When a plan calls for prescription care such as hormone therapy or medication-supported weight loss, that piece is handled through the clinic's clinical team, under the same roof.
Consultations are by appointment. Request one through the consultation form or call (636) 590-4686.
When symptoms deserve a deeper look
Many patients arrive after trying to manage fatigue, weight changes, digestive issues, brain fog, inflammation, hormone symptoms, or stubborn metabolic concerns on their own. Functional medicine asks a better question: what patterns may be driving the problem, and which levers are most worth addressing first?
The symptom clusters below are the ones evaluated most often here. Each links to a page that goes deeper, so you can check the fit before you book.
- **Tired all the time, cold, gaining weight, losing hair.** A thyroid workup that looks beyond TSH alone is the usual starting point. - **Bloating, unpredictable digestion, food reactions.** SIBO evaluation and treatment is one common path when gut symptoms have been labeled IBS and left there. - **Wired at night, flat in the morning, running on caffeine.** The HPA-axis and "adrenal fatigue" page explains what that pattern usually means and how it is assessed. - **A diagnosed autoimmune condition, or antibodies with no plan.** Functional medicine for autoimmune conditions works alongside your rheumatologist or endocrinologist. - **Weight that will not budge despite real effort.** Weight-loss resistance is rarely just calories. The natural weight-loss program looks at thyroid, cortisol, insulin, and gut function before assuming the problem is willpower. - **Hot flashes, low libido, mood swings, cycle changes.** Hormone symptoms are evaluated here, and when bio-identical hormone therapy is appropriate, it is prescribed and managed through the clinic's clinical team.
If your symptoms cross several of these lines, that is normal. Overlap is usually the point.
What functional medicine evaluates
Depending on the case, evaluation may include blood, saliva, urine, or stool testing, along with review of cardiovascular markers, thyroid and adrenal patterns, sex hormones, nutrient status, food sensitivity questions, gut and microbiome concerns, toxin exposure, inflammation, and genetic context. Testing is not used to overwhelm you; it is used to sharpen the plan.
### What a first visit typically looks like
A functional medicine evaluation typically moves through four steps. The order matters more than the speed.
1. History first. The first visit is mostly conversation: when the symptoms started, what has been tried, what changed, what your days look like. Bring recent labs and a list of medications and supplements so nothing is repeated unnecessarily. 2. Targeted labs. Based on that history, labs are ordered when they will change the plan. That may be a conventional blood panel, a specialty test, or both. Not every patient needs specialty testing. 3. Review visit. Once results are back, you go through them together to see which patterns are worth acting on first and which findings are background noise. 4. A plan. Nutrition, lifestyle, targeted supplements, and, where appropriate, a referral or prescription care through the clinic's clinical team. The plan is meant to be followed, not admired.
Visit length, lab turnaround, and whether a short discovery call comes before the full evaluation vary by case. Ask when you request a consultation and the office will walk you through the sequence.

Why one-size-fits-all wellness fails
A supplement, diet, or protocol that helps one person may be the wrong move for someone else. Functional medicine is strongest when it turns scattered symptoms into a prioritized strategy: what to change, what to measure, what to support, and what to stop wasting time on.
A plan you can actually follow
The clinic may combine nutrition strategy, lifestyle coaching, targeted supplement support, weight-loss planning, hormone evaluation, digestive support, or referral when another medical path is more appropriate. The outcome is not a generic wellness lecture; it is a practical next step matched to your health picture.
Functional medicine works best alongside, not instead of, appropriate conventional medical care. Dr. Deloney does the evaluation and the nutrition and lifestyle plan. In Missouri, chiropractic scope includes ordering lab tests but not prescribing medication (RSMo 331.010), so any prescription-based care is provided through the clinic's clinical team. You are told which is which before it starts.
A word on evidence before you spend money. One Cleveland Clinic cohort study, published in JAMA Network Open in 2019, found that patients in its functional medicine center reported larger improvements in physical health at six months than comparable primary-care patients; the authors described an association, not proof, and called for prospective trials. Critics of the field and a 2026 practitioner editorial agree on one point: outcomes evidence for the functional medicine model as a whole is still limited, even where individual pieces of it are well supported. That is why the clinic frames this as evaluation and a plan, not a cure for any condition.

Cost, insurance, and what to ask the office
Many functional medicine practices in the United States are cash-pay, and specialty labs and supplements are usually not covered by insurance even when a standard blood panel is. Some practices provide a superbill you can submit for possible out-of-network reimbursement, and HSA or FSA funds can generally be applied to qualifying medical expenses. Before your first visit, ask the office how the evaluation is billed, whether labs go through your insurance, and whether a superbill is available. Fees are not published here because they depend on what your case needs.
Start with clarity
If you feel stuck, inflamed, exhausted, metabolically off, or confused by conflicting health advice, request a functional medicine consultation. The first win is understanding what deserves attention and what path is most likely to fit.

▸What does a functional medicine evaluation include?
A functional medicine evaluation reviews symptoms, history, lifestyle, and labs, which may include blood, saliva, urine, or stool testing across thyroid, adrenal, sex hormones, nutrients, gut, inflammation, and metabolic markers, to turn scattered symptoms into a prioritized plan.
▸How is functional medicine different from a regular doctor visit?
A standard visit usually treats one symptom or system at a time. Functional medicine connects the dots across hormones, metabolism, gut, sleep, and inflammation to find the upstream driver, then builds a practical plan you can follow. It is meant to work alongside your regular medical care, not replace it.
▸How much does functional medicine cost, and does insurance cover it?
Many functional medicine practices are cash-pay, and specialty labs and supplements are usually not covered. Some clinics provide a superbill for possible out-of-network reimbursement, and HSA or FSA funds can often be used. Fees depend on your case, so ask the office how the evaluation and labs are billed before your first visit.
▸What should I bring to a first visit?
Recent lab results, a list of current medications and supplements with doses, and a short timeline of when your symptoms started and what you have already tried. If you have prior imaging or specialist notes, bring those too. Most of a first visit is usually history, so the more of that you have in hand, the more useful it is.
