Functional medicine

Looks for the root cause of symptoms through specialized testing.

Functional medicine is the medical foundation of care at WIN: a way of practicing medicine that looks for the root cause of a symptom through a detailed history and specialized laboratory testing, then treats what the labs reveal. At our Houston and San Juan centers, Dr. Carmen Báez-Franceschi, a board-certified pediatrician, uses it to build the medical plan for infants, children, teens and adults before any therapy begins.

What is functional medicine?

Functional medicine asks a different first question. Instead of "what is this symptom called?", it asks "why is this body producing this symptom?" A child's inattention, speech delay or chronic stomach pain may have medical contributors underneath it: nutritional deficiencies, food allergies, exposure to environmental toxins, metabolic or hormonal imbalances, or genetic variants that change how the body processes nutrients. Functional medicine looks for them systematically and treats them so the body has what it needs to function.

It is not "alternative medicine" that rejects conventional care. At WIN, functional medicine is practiced by a board-certified pediatrician who prescribes conventional medication when it is medically needed and integrative protocols (dietary modification, individualized supplementation, homeopathy) when those fit better. It is also not a diagnostic label for autism or ADHD; it is a method for understanding and treating the medical picture behind a diagnosis.

Who functional medicine helps

Functional medicine is part of every WIN plan, because every patient begins with the same medical evaluation. It is especially central for children and adults with:

WIN treats infants, children, adolescents and adults. Functional medicine is not purchased as a stand-alone test menu: which labs are ordered, and what is done with the results, is decided by the physician after the initial evaluation, for each patient individually.

What a visit looks like at WIN

Functional medicine at WIN begins with the Phase I initial medical evaluation, in person at the Houston or San Juan center. The appointment is three-part and typically takes about 1 to 1.5 hours with the physician and about 3 hours in the office. Dr. Báez-Franceschi reviews the full medical history, prior treatments and current symptoms with the parents, examines the child and runs medical and neurodevelopmental tests. Families leave with an initial treatment plan and lab orders.

The specialized labs depend on the patient and may include genetic testing, a food allergy panel, environmental toxins, nutritional deficiencies, metabolic panels and hormone panels. Samples are collected the way each lab requires; the team explains what to expect so parents can prepare their child.

At the follow-up appointment, once labs are complete, the physician explains the results in plain language and builds the protocol. Parents are told what each finding means, what will be addressed first and how it will be rechecked. The physician screens for any condition, medication or allergy that would change a recommendation.

How it fits the Franceschi Method®

Functional medicine spans Phase I (evaluation and planning) and Phase II (evaluation results and protocols) of the Franceschi Method®. The labs ordered in Phase I feed the medical and nutritional protocols of Phase II: nutrition and individualized supplementation built on the findings, genetic testing that explains how an individual body handles nutrients and detoxification, and, for expecting parents, the prenatal consultation.

Treating the medical picture first is deliberate. A brain that is inflamed, underfed or coping with discomfort has a harder time responding to therapy, so the Phase III therapies are layered on a body that has been given what it needs. Progress is measured throughout with re-evaluation and repeat labs where indicated, and parents receive reports and training as part of the team.

What families can expect

After the initial in-person evaluation, many functional medicine follow-ups can be done by telemedicine for families in Texas, Florida and Puerto Rico; international families travel to Houston or San Juan. Protocols are adjusted as results come in, so the first months involve a few visits and then a steadier rhythm. Early changes families often report, hedged because each child is different, are in sleep, digestion, energy and mood, with attention and language gains building on top as the therapies begin.

Not sure whether your child's symptoms have a medical cause no one has looked for? An orientation is the place to ask. Request an orientation with our Houston or San Juan team, in English or Spanish, and we will walk you through how the evaluation works and what it could reveal.

“She really knows how to identify the causes of his attention deficit. It is not a standard treatment — this method adapts to the needs of each patient. My treatment plan will not necessarily be your treatment plan. That’s how personalized it is.”

Wellness Institute of Neurodevelopment is excellent. It was precisely what I was looking for and needed for my son. As soon as my son started his treatment with Dr. Baez Franceschi, the improvement was notable and consistent. I loved that they treat patients with love, empathy and respect. She really knows how to identify the causes of his attention deficit. Today my son with ADHD is an honor student, volleyball player and the most communicative, loving and emotionally stable boy (almost teenager). Like everything in life, ADHD is a process. WIN helps you understand it, work through the hard times and thrive. Not every case is the same. Why? Because it is not a standard treatment. This method adapts to the needs of each patient. My treatment plan will not necessarily be your treatment plan. That’s how personalized and great it is. Thank you WIN!

After bringing my daughter who is level 2 autistic, I started seeing great results after a few weeks. I had previously taken her to different doctors but nothing changed. She hardly slept at night & couldn't focus. After taking tests & getting to the root of the issues she had, the doctor created a specialized plan for her. I'm grateful for all the help. My daughter's behavior and focus continues to improve and she is sleeping better at night. In just a few weeks her health has improved.

Common questions

What is functional medicine, and how is it different from a regular pediatric visit?

A routine pediatric visit is usually short and focused on the presenting complaint: a diagnosis is named and a treatment for the symptom is offered. Functional medicine takes a longer history and uses specialized labs to look for the reasons behind the symptom, such as deficiencies, food allergies, toxins, or metabolic, hormonal and genetic factors, and treats those. At WIN, both happen under the same roof: Dr. Báez-Franceschi is a board-certified pediatrician, so conventional and integrative care are part of one plan.

Which lab tests does WIN use in functional medicine?

The specialized laboratories depend on each patient's needs and the physician's recommendations. They may include genetic testing, a food allergy panel, environmental toxins, nutritional deficiencies, metabolic panels and hormone panels. Not every patient needs every test; the physician chooses at the initial evaluation and explains each result at the follow-up.

Does functional medicine replace my child's pediatrician or medication?

No. WIN works alongside your child's pediatrician and specialists, and we ask you to keep those relationships. If your child takes medication, do not stop or change it on your own; bring the list to the evaluation. WIN's approach is to treat the cause rather than mask the symptom, and medication is used when it is medically necessary as part of a comprehensive plan.

Can functional medicine follow-ups be done by telemedicine?

Often, yes. The initial evaluation is in person in Houston or San Juan, and after that many follow-ups and lab reviews can be done by telemedicine for patients in Texas, Florida and Puerto Rico. Some rechecks or sample collections still require a visit, and the team will tell you which ones.

Do you accept insurance?

Please contact our team for current information on insurance, payment options and what to expect for your plan — it varies by location and by service. We will walk you through it before your first visit.

Do I need to travel to Houston or San Juan, or can we start remotely?

Telemedicine is available for families in Texas, Florida and Puerto Rico, and many families start that way. The WIN neurodevelopment evaluations and the Phase III therapies happen in person at our Houston or San Juan centers; international families are welcome at both.

Which therapy is right for your family?

Every plan starts with an evaluation. Let’s talk.
