Root-cause medicine vs. disease-care medicine: the actual difference
There is no fight between functional medicine and primary care. They are built for different jobs. The trouble starts when patients use one to do the other.
What disease-care medicine is built for
Conventional primary care is excellent at acute illness, infections, screening, and managing diagnosed disease (diabetes, hypertension, established autoimmune conditions). A seven-minute visit and a small panel of routine markers is appropriate for that job. The system is designed for high throughput and standardized care, and it largely works.
Where it stops working is the gap between “no diagnosable disease” and “feeling well.” A normal CBC, lipid panel, and TSH does not mean a patient is well. It means a patient is not sick in any of the ways those eight markers can detect.
What root-cause medicine is built for
Functional and integrative medicine occupies that gap. The bet is that early dysfunction shows up in markers conventional care does not run, and that you can resolve symptoms without a diagnosable disease ever being assigned.
Practically, that means three things that are different from a standard visit:
- 60 minutes of intake, not 7. The history is where most of the answers are, but it takes time to actually surface them.
- 100+ markers run together, not 8. The diagnostic question is not “does this person have disease X.” It is “which systems are starting to drift, and how do they affect each other?”
- A protocol, not a prescription. The output of a root-cause workup is a written plan that addresses food, sleep, movement, supplements, sometimes prescriptions, and a recheck schedule. The plan is iterated based on what labs show, not on a calendar.
Which one do you need?
If you have an acute or diagnosable problem, see your PCP. If your insurance covers a specialist for it, see the specialist.
If you have been told your labs are normal but you still feel unwell, that is the gap functional medicine was built for. The 60 minutes are the product.
What we do (and do not do)
We are not a replacement for your PCP. We do not manage emergencies. We do not prescribe scheduled medications. We coordinate with your existing providers and never ask you to stop a medication without their input.
What we will do is order the lab panel your PCP did not, spend the hour your last visit did not have, and build a plan around what your biology is actually doing – see the full 7-panel breakdown or see what it costs.
