Hello, I ve been to my general practitioner several times but not sure i m getting anywhere. My symptoms include: fatigue, brain fog, tired eyes After multiple tests it s been determined I have: high cholesterol (very high), low testosterone (very low) low vitamin D level. Had a brain MRI (all good), tested for Diabetes and no signs of diabetes. My questions is do these symptoms indicate a larger issue? is there a specialist I should be consulting? Endocrinologist? Cardiologist? My general practitioner doesn t seem to have any insight beyond Diet and Exercise...
