You've done everything right — seen the doctors, run the tests, followed the advice. Parsley is for when none of it worked and you're still looking for answers.
Care for unexplained symptoms, even when tests look normal
"I came trying to connect the dots between multiple different health conditions over a 15-year period, which had stumped over 30 doctors across three states. This led to a root cause diagnosis that connected all of my health conditions."

Why unexplained symptoms are often missed
Traditional care is designed to identify and treat specific diseases. When symptoms span multiple systems or fall outside clear diagnostic thresholds, contributing factors may include:
Subtle hormone or metabolic imbalances
Inflammation that does not meet diagnostic cutoffs
Gut health issues that affect other systems
Stress, sleep disruption, or nutrient deficiencies
Interactions between multiple systems rather than a single cause
A physician-led model that combines conventional and functional medicine
Parsley Health delivers functional medicine through a physician-led clinical model designed to be consistent, evidence-based, and deeply personalized. Our clinicians are board-certified and conventionally trained, with additional fellowship training in evidence-based functional medicine. Care is guided by shared clinical protocols and continuously refined through outcomes data, research, and physician oversight.
Our approach to unexplained symptoms is right for you if you have:
Ongoing symptoms that have not improved despite normal or inconclusive test results
Seen multiple providers but still do not have clear answers or a path forward
Symptoms that affect multiple areas of your health and do not fit into a single diagnosis
A desire for thoughtful, whole-body medical care that takes your experience seriously
How Parsley approaches unexplained symptoms
Most of your symptoms have a pattern. We're trained to find it.
In-depth medical visits that explore symptoms, history, and lived experience
Review of existing labs, imaging, and prior records
Advanced and specialty testing when appropriate
Attention to how systems interact, including hormones, gut health, immune function, metabolism, and mental wellbeing
Ongoing follow-up to adjust care as patterns emerge

I've been trying to get better for over a decade. Being told over and over 'everything's normal, it's just anxiety' is maddening. Just the labs alone were so helpful. I now have an actual direction to move forward in instead of the circles I'd been going in for years.

Progress you can see and feel
We use our proprietary, clinically-validated Parsley Symptom Index (PSI) to track progress in our care. Parsley members complete the PSI before their first visit and consistently over time establish a baseline of symptom severity and track clinical progress. Nearly 9 out of 10 members report symptom improvement within their first year of care.
