I have high cholesterol - 7.6 just now and has been 8.4 in the past - healthy lifestyle etc - told by Gp possibly genetic. Not on statins.
OK - so here is my theory and both my GP and the endo didn't agree with my thoughts.
If your thyroid is working very slowly and your metabolism is slow - hence weight gain etc etc - how about how we metabolise fats and if that is slow then then can sit in the body longer adn hey presto, high cholesterol!!!!????
Others thoughts would be interesting?
