Functional Longevity Academy

Welcome to Functional Longevity Academy, a channel dedicated to helping providers move beyond symptom management and practice real root-cause, functional, and longevity medicine.

I’m Stacy Welker, FNP-C, ABAAHP, a functional and longevity medicine provider and educator. After working in emergency medicine and later as a first assist in trauma and general surgery, I began seeing patterns—chronic disease progression, medication dependence, and care focused on managing symptoms instead of addressing causes.

This channel exists to change that.

Here, you’ll learn how to think through a functional medicine lens, connect gut health, hormones, inflammation, metabolism, and mitochondrial function, interpret labs beyond “normal,” and integrate functional and longevity medicine into real clinical practice.

This channel is designed for nurses, NPs, PAs, and providers who want a better framework to help patients heal—and a more sustainable way to practice medicine.
