Statins and how they work

Statins are a group of medicines that work to lower your cholesterol. According to the Mayo Clinic, statins are able to lower cholesterol by blocking a substance your body needs to make cholesterol. Statins may also help your body reabsorb the cholesterol in your arteries, which could be causing blockages. By doing this, the lower cholesterol levels may prevent heart disease, heart attacks or strokes.1

Some common names of statins are atorvastatin, simvastatin, rosuvastatin, pravastatin, lovastatin.

Statin treatment for heart disease and diabetes

Taking statins usually depends on your cholesterol levels and heart health. People with diabetes, for instance, can often be at high risk for heart disease.2 A symptom of diabetes can be high blood pressure, which may lead to heart disease, so those who deal with diabetes may benefit from statins.

If you have one or more of the following risk factors, talk to your doctor about whether adding a statin to your therapy might be right for you:

  • High cholesterol
  • Diabetes
  • High blood pressure
  • Smoking

Possible side effects and interactions

Always talk to your doctor if you experience any side effects or unusual symptoms. Statin medication can have possible side effects or interact with food or other drugs. It is good practice to keep a list of all the medications, supplements and over-the-counter drugs you are taking, so you can let your doctor know.

If you have taken a statin before and experienced any side effects, let your doctor know. Your doctor may be able to switch you to another statin with a lower risk of side effects.

More on diabetes and heart disease

Diabetes is a disease in which your body no longer makes enough or responds to insulin. Due to this, your body is unable to process blood sugar, which increases the chances of having:

  • High blood pressure
  • Blindness
  • Nerve damage

These changes in your body also put you at a greater risk for heart disease. Heart disease is a condition that can be caused by high cholesterol and high blood pressure, among other factors, that may result in heart attack and stroke.
