High doses of statin drugs do not always lead to diabetes. Taking statin drugs may lead to an increased risk of developing type 2 diabetes, states WebMD. However, the benefits on staying on the drugs outweigh the risks.
A study published in 2014 showed that people on statin drugs had a 12 percent increased risk of developing type 2 diabetes over four years, states WebMD. The study, published in the English medical journal The Lancet, showed a correlation among decreased blood cholesterol, increased blood sugar and weight gain. Participants in the study gained a small amount of weight, which may explain the increased risk of diabetes, notes the study's coauthor, Dr. David Price.
Statin drugs are correlated with other side effects, including muscle weakness and liver damage, states WebMD. A study of 2 million statin users found that high doses may lead to kidney problems. The 2013 study, published in the British Medical Journal, is inconclusive about how or whether statin drugs damage the kidneys. The study's authors recommend concerned individuals discuss their risks with their doctors.
Statin drugs lower blood cholesterol and are prescribed to patients at risk of heart disease.
Statin drugs include the brand names Crestor, Lipitor and Zocor. Studies show that statins can reduce the risk of heart attack, stroke and death from heart disease by 25 to 35 percent, states WebMD.
