I have been experiencing some symptoms of low testosterone for a couple of years now (low libido, loss of morning erections, brain fog, etc. I honestly figured it was just part of getting older and being overweight. Over the past few years I have lost about 60 pounds while exercising more and eating better. While I do feel better, I never really found a huge improvement in these symptoms.
So on a whim, I had a testosterone blood test done and it came back low. Since then I have seen my general practitioner and an endocrinologist with lots and lots of blood work in between. A summary of the blood work is below.
At the request of my GP, I completed a sleep study. The results surprised me with a diagnosis of moderate case of sleep apnea. I have a titration study scheduled in a few weeks for a CPAP machine.
I have a follow-up appointment scheduled with the endo in a few weeks. Can you please review my labs and let me know what follow-up questions I should be asking at the appointment? I’d like to go into the appointment as an educated consumer if possible.
What is the current thinking on the link between low testosterone and sleep apnea? I have read conflicting things. Some say there is a link and others say no link.
Obviously my weight is an issue and I continue to work on that.
