Hello,
Statin drugs are known to have a side effect of raising blood sugars / inducing diabetes. They also have many other side effects. If you do take them, please make sure you also take a CoQ10 supplement, as they deplete your body's CoQ10 (which is critical for cardiac health).
It would be better if you can manage your cholesterol though dietary measures. Against what one would think as common sense a low carb diet (high fat, moderate protein), along with regular and intense exercise, can effectively reduce cholesterol. A regular glass of red wine (remember moderation) may also help.
Fats should be natural sources under such a diet (ie. olive oil, coconut oils, cold pressed nut oils, unprocessed dairy), and avoid transfats (manmade and processed fats), strictly limit fructose from all sources (particularly high fructose corn syrup - but also limit fruits). Carbs should come from plenty of non-starchy vegetables. Avoid processed foods.
Hope this can help.
I am also having higher blood sugars since i have been put on pravastatin. I have been on it now for about 2 months. I take 10 mg. at night
Nothing indicated here on Pravastatin raising glucose levels.
