Hopefully this is enough info to get you started:
1. What is Functional Medicine?
The video below highlights the difference between a "functional medicine" approach to health (where they actually try to identify and eliminate the cause of your problems), versus a "conventional medicine" approach (where all they want to do is cut things out and/or pile one drug on top of another).
In less than 10 minutes, you'll see how a person can use "normal doctors" for years without solving anything, then use a "functional medicine" approach and completely transform their health in just 5 months. (It's Dana White's story.)
2. Cleveland Clinic's Functional Medicine Program
This is a link to the Functional Medicine division at Cleveland Clinic. You could call them and say: "I'm 'xx' years old and I want to start moving in a healthier direction."
The good thing with functional medicine is that they actually spend a lot of time looking at you as an individual, and they have a support structure to help you get and stay on track. One of the most important things they'll teach you is that FOOD can either be poison or medicine.

Regarding "poison food," ultra-processed foods (UPFs) are everywhere, and so is the chronic disease that they cause. When people swap their UPFs for single-ingredient, organic whole foods, their disease rates plummet.

Top 10 UPF Poisons4. Comprehensive Testing
I've provided a link to a company that will perform 100 different tests on your blood for under $500. (The company is run by the same guy who helped Cleveland Clinic launch their functional medicine division.)
This way, if you want some insights now into what's going on and what you can do, you won't have to wait for an appointment with a functional-medicine doctor.

Last but not least, if you want to try a popular UPF-elimination diet (carnivore or maybe carnivore lite) to see how it affects you after a month, it's an easy way to detox your body. The range of benefits people report are pretty amazing.
Here is one guy's story, but there are many others online. (This guy's metabolism was completely trashed, he was hundreds of pounds overweight and, of course, had other health problems too: diabetes, major depression, high blood pressure, etc.)
