Podcast with Dr. Alan Segal on Potassium

November 18, 2021

In this episode Alan is back to complete our physiology TRIFECTA by discussing potassium. While talking about water and protons was a total blast on our previous podcasts, Potassium is really Alan's wheelhouse. I really enjoyed this podcast and although I've worked on potassium channels in Alan's lab and I've been in clinical nephrology practice for 20 years now I still walked away with new lessons that will impact how I practice medicine. If you love potassium you will love this podcast!! Enjoy (don't forget to like and subscribe to THL)
