Iv`e had a mild problem with my thyroid for some years now, & at first I was just monitered because i had no symptoms. Recently my cholesterol levels began to rise so my doctor put me on Simvastatin. The drugs made me very tired & achy, & I kept falling asleep all the time. I stopped taking them because of this. My gp said that an underactive thyroid can cause high cholesterol so I went onto Levothiroxine. I got the results of my latest blood tests yesterday, & although everything else is fine, my cholesterol is still high at 6.5. I don`t want to take statins again, & I`m on a healthy diet & exercising, so why can`t I get my cholesterol down? I`m very scared that I`ll have a heart attack at any time. Is there nothing that I can do besides go back on those dreadful pills?
