After my initial diagnosis in late 2010, despite having no classical signs of insulin resistance, I followed the normal wisdom of starting a statin. I needed only 10mg of Simvastatin to get my cholesterol down to 3.5. I stopped the simva 15 months later as I recognised that I was very intolerant to it. My main problems were generalised aches, muscle wasting and weakness with calf muscle and tendon tears on exercise [I was finding it difficult to continue my twice weekly 5-10km jogs due to musculoskeletal tears]. Further data on the link with diabetes convinced me to stop the statin.
Subsequently, I felt so much better that I realised that the statin was causing low mood, insomnia,slow cognition, peripheral neuritis, constipation, some ED and others! I have taken Co Q10 since, in the hope that it might repair some of the damage.
There is, I feel, a group of individuals who are likely to get similar adverse effects on statins.
Since I have no metabolic syndrome features, I am not concerned that I am not taking statins. I might feel differently if I was obese and had established arterial disease or whatever.
