Am now taking statins for cholesterol (12.5). After a recent blood test I have also been diagnosed with Hypothyroidism. My doctor says this is the cause of my high cholesterol. I have felt anti-social and "just can't be bothered with people" for years. Going to bed at 3 pm and sleeping my life away. Am feeling like a new person now I'm on thyroxin. I just wanted to point out that there can be hidden reasons for high cholesterol.
If you feel tired and cold all of the time. Dry skin and generally grumpy and like to be alone. You should have your thyroid level checked.
