What is Functional Health?
What is functional health?
Functional health looks at why you feel off — gut, minerals, hormones, sleep, toxins — instead of only naming a diagnosis or masking a symptom. Conventional care is excellent in a crisis. This work is for the unexplained: fatigue, brain fog, digestion, mood, weight that won’t stay put. Labs show the terrain. Daily habits (nutrition, movement, rest, people, peace) keep it. Petronella Functional Health uses EquiLife at-home tests plus the N.U.R.S.E.™ protocol. It does not diagnose, treat, or cure disease.
How is functional lab testing different from a regular checkup?
A checkup asks whether you already have a disease, using wide “normal” ranges. Functional labs look for patterns — nutrients, metals, gut bugs, food reactions, cortisol rhythm, thyroid, inflammation — often before a disease label. Many samples are urine, stool, saliva, or hair at home, not only a blood draw. They sit beside your physician’s work, not instead of it.
Do functional labs replace my doctor or annual bloodwork?
No. Keep your physician for diagnosis, prescriptions, and emergencies. Functional testing is extra data for lifestyle and supplement decisions. If a result looks urgent, take it to your doctor.
How do I know which test to take?
Gut and bloating often start with Candida/Metabolic/Vitamins and sometimes Stool. Fatigue across systems often starts with Minerals and Metals. Food reactions that hit a day or two later point to IgG sensitivity. Stress, libido, and slow metabolism point to the Hormone/Metabolism panel. When symptoms span more than one system, a small bundle (Starter Kit or Big 5) beats a random single test. Use the symptom matcher, then a free discovery call.
Why do my regular labs say “normal” if I still feel terrible?
“Normal” is a population average, often aimed at disease, not vitality. You can sit in-range and still have low-optimal thyroid, minerals, or inflammation that match fatigue, fog, or poor sleep. Functional ranges are tighter. The goal is the pattern that fits your picture, not a contest with the lab printout.
What is the difference between a food allergy and a food sensitivity?
Allergy is usually IgE — fast, sometimes dangerous (hives, swelling, anaphylaxis). Sensitivity is often IgG — delayed, 24–72 hours: bloating, fog, skin, joint ache. Allergy belongs with a physician. Sensitivity testing can show delayed reactions a standard allergy panel misses.
How long does a functional health protocol usually take?
After results, most rebuild/detox blocks run about 12–16 weeks, with monthly check-ins. That is long enough to change terrain and short enough to stay honest. Re-test (often twice a year) beats guessing when to stop supplements. Habits from N.U.R.S.E.™ — nutrition, using your body, rest, social connection, explore peace — are what remain after the bottles.
Are at-home functional labs accurate?
They are useful when collection is done right and a trained person reads patterns, not one scary number. Hair minerals show tissue trends and excretion, not a blood lead emergency. Stool and urine show gut and metabolites you won’t see on a basic CBC. Follow the kit. Don’t use kitchen scissors on a hair sample if they might be aluminum. Confirm anything alarming with your doctor.
Can an integrative health practitioner diagnose or treat disease?
No. An IHP (including IHP3) is not a licensed medical doctor. We do not diagnose, treat, or cure. We investigate roadblocks with labs and coaching — food, sleep, stress, minerals, gut — and you keep your physician for medical care. If you need a diagnosis, start there. If you need a map for the unknown, that’s this work.
