Chronic infections & parasites in children · Functional medicine

When your child keeps getting sick, the pattern needs a deeper map.

Recurrent strep, lingering viral recovery, parasite concerns, yeast patterns, chronic gut symptoms, fatigue, and immune flares can all overlap. We help parents organize the infection history and decide what needs testing, treatment, support, or referral.

What parents are facing

Chronic infections & parasites is rarely just one symptom.

Families usually arrive here after months or years of treating isolated symptoms while the bigger pattern keeps showing up at home. We look at the timeline, the body systems involved, the testing already done, and the clues that may have been missed.

  • Your child has symptoms that keep returning, shifting, or affecting daily life.
  • Standard testing may have ruled out urgent problems without explaining why this is still happening.
  • You need a clinician who can connect gut, immune, food, infection, sleep, nutrient, and environmental clues.
Root-cause map

What we investigate before recommending a plan.

Timeline

When symptoms started, what changed before the first flare, what makes symptoms better or worse, and what has already been tried.

Gut and food patterns

Constipation, reflux, picky eating, bloating, food reactions, microbiome balance, and gut barrier clues.

Immune load

Recurrent infections, allergies, autoimmune history, inflammation, PANS/PANDAS clues, and post-viral or tick-borne patterns.

Environment

Mold, water damage, seasonal triggers, chemical exposures, sleep space, school exposures, and other hidden stressors.

Nutrient status

Iron, vitamin D, magnesium, zinc, omega-3s, methylation needs, and other deficiencies that can affect resilience.

Real-life fit

What your child will tolerate and what your family can realistically sustain without burning out.

Simple plan

Start with the next right clinical step.

The free consult helps determine whether your child is a fit for a full intake, focused gut testing, 4-month concierge care, or a different referral first.

  1. 01

    Start with fit.

    Tell us what your child is dealing with and what care you have already tried.

  2. 02

    Map the drivers.

    If we work together, we review the timeline, symptoms, labs, medications, diet, sleep, and environment.

  3. 03

    Follow a written plan.

    You leave with prioritized next steps for testing, food, supplements when appropriate, routines, and follow-up.

Clinical deep dive

What parents need to know about chronic infections & parasites.

When illness never feels fully over.

Some kids catch everything and recover slowly. Some have recurrent strep, ear infections, sinus infections, yeast, belly pain, fatigue, swollen glands, headaches, or behavior changes after illness. Some families suspect parasites because of travel, daycare exposure, animals, swimming, chronic diarrhea, nighttime itching, or unexplained gut symptoms.

The goal is not to label every child with a chronic infection. The goal is to stop treating each episode like it is unrelated when the pattern says otherwise.

Conventional care still matters.

Acute infection symptoms need appropriate medical care. Fever, severe pain, dehydration, breathing trouble, neck stiffness, blood in stool, severe diarrhea, persistent vomiting, a child who looks very ill, or any concern for sepsis or meningitis needs urgent evaluation.

Some infections require prescription treatment. Some require testing through a pediatrician, infectious disease specialist, GI specialist, urgent care, or emergency department. Calm Wellness adds the longer-pattern lens.

Patterns we investigate.

Depending on the child, we may review:

  • Recurrent strep, ear infections, sinus infections, pneumonia, or bronchitis.
  • EBV or mono-like illness followed by fatigue, headaches, or low stamina.
  • Parasite clues such as persistent diarrhea, abdominal pain, travel exposure, water exposure, anal itching, or household spread.
  • Yeast or thrush patterns, especially after repeated antibiotics.
  • Gut symptoms that started after antibiotics or infection.
  • Sudden anxiety, OCD, tics, regression, rage, or urinary frequency after illness, which can point toward PANS/PANDAS.
  • Mold or tick exposure that may be keeping the immune system activated.
  • Nutrient status, sleep, stress, protein intake, and immune resilience.

Testing may be part of the map.

Testing depends on the story. It may include stool testing, parasite evaluation, immune markers, inflammatory markers, nutrient labs, tick-borne testing, mold or mycotoxin testing, or review of prior pediatrician and specialist labs.

The point is not to chase every possible microbe. The point is to answer the next practical clinical question: what is keeping this child from recovering?

How gut health fits in.

The gut is one of the major interfaces between the immune system and the outside world. Repeated antibiotics, infections, low beneficial bacteria, yeast overgrowth, parasites, constipation, and poor digestion can all affect resilience.

For children whose infection history is paired with constipation, reflux, diarrhea, belly pain, food reactions, eczema, or picky eating, gut testing often becomes a useful starting point.

What care can look like.

Some families need the Initial Functional Medicine Intake to organize a complex infection history. Others fit the 4-Month Concierge Package because infection, gut, immune, mold, Lyme, and nervous-system symptoms are all involved.

We work alongside pediatricians and specialists. With consent, we can help parents organize the story, share relevant findings, and advocate for a more complete workup.

Common questions

Things parents ask us about this.

Do you test every child for parasites or chronic infections?

No. Testing should follow the story. We look at exposure history, stool symptoms, recurrent illness, travel, water exposure, antibiotic history, immune clues, and prior labs before deciding whether stool testing, infection markers, tick-borne testing, or another workup makes sense.
