Statins have also been shown to increase your risk of diabetes via a number of different mechanisms. The most important one is that they increase insulin resistance, which can be extremely harmful to your health. Secondly, statins increase your diabetes risk by raising your blood sugar. Statins work by preventing your liver from making cholesterol.
As a result, your liver returns the sugar to your bloodstream, which raises your blood sugar levels. These drugs also rob your body of certain valuable nutrients, which can also impact your blood sugar levels. Two nutrients in particular, vitamin D and CoQ10, are both needed to maintain ideal blood glucose levels. A 2011 meta-analysis confirmed the higher the dosage of statin drugs being taken, the greater the diabetes risk.
Cholesterol is also essential for your brain, which contains about 25 percent of the cholesterol in your body. It is critical for synapse formation, i.e. the connections between your neurons, which allow you to think, learn new things, and form memories. So perhaps it’s not surprising that memory loss is widely reported in association with statin use.
Further, remember that statins reduce ketone production. Ketone bodies are used as fuel by your brain, and they have also demonstrated the capacity to protect against neuronal disease, seizures, and age-related brain diseases, such as Alzheimer’s, Huntington’s, and Parkinson’s. Researchers from Penn State College of Medicine even found statins were associated with an increased Parkinson’s risk.16
High total cholesterol and LDL were also associated with a lower risk of Parkinson’s disease. The study concluded, “Statin use may be associated with a higher PD [Parkinson’s disease] risk, whereas higher total cholesterol may be associated with lower risk.”
