I've heard that a Functional Medicine Practitioner can help me reduce the amount of medication I take, is this possible?

We're not doctors and we would never advise you to stop or reduce your medication.

It's possible that addressing imbalances in your body could improve your symptoms to the point where you need less medication. If you do start feeling better, this is something you should discuss with your doctor.

There's a lot of scientific evidence linking the health of your gut to your overall physiology.

If you want to reduce your symptoms, working with an experienced practitioner is a good start.
