Statins are one of the most commonly used medicines in the world. They are mainly taken to lower cholesterol levels and reduce the chances of having a heart attack or stroke.
For many people, statins have saved lives. But like all medicines, people wonder if statins might affect other parts of the body, such as the kidneys.
Researchers have been studying this to understand whether statins are good, bad, or have no big effect on kidney health. Here’s what they’ve found so far, explained in simple terms.
Statins work by blocking a chemical in the liver that helps the body make cholesterol. High cholesterol can block blood vessels and raise the risk of heart problems. By lowering cholesterol, statins help keep blood flowing and protect the heart.
Because statins are so helpful for heart health, doctors often give them to people with diabetes, high blood pressure, or other conditions that make heart disease more likely. But what about their effect on the kidneys?
Some research shows that statins might help the kidneys. They can reduce inflammation and improve how blood vessels work. Since kidneys need good blood flow to work well, this could be a good thing. For people with diabetes or high blood pressure—two major causes of kidney disease—statins might lower the chance of kidney damage.
But there are also some concerns. In rare cases, statins can lead to a condition called rhabdomyolysis. This happens when muscle cells break down and leak into the blood. These substances can hurt the kidneys.
Rhabdomyolysis is not common, but it is serious. It happens more often when people take very high doses of statins or combine them with other drugs. Anyone taking statins who has strong muscle pain should talk to a doctor right away.
There’s also some debate about whether statins increase the risk of kidney problems after surgery or in people who already have weak kidneys. Some studies suggest that statins might make a sudden kidney problem, called acute kidney injury (AKI), more likely.
But other studies have found the opposite—that statins might actually protect against AKI in some people, especially during heart surgery.
People with long-term kidney disease, also known as chronic kidney disease (CKD), often take statins because they are at high risk of heart problems. For them, statins are usually helpful.
But for people with very advanced kidney disease who need dialysis, the benefit is less clear. In these cases, studies have shown that statins may not lower heart risks much and might not be needed.
Overall, most research shows that the benefits of statins are greater than the risks for most people, especially those with high cholesterol or heart disease risk. Doctors look at a person’s full health picture before giving statins.
It’s important to follow medical advice and report any new or strange symptoms—like muscle pain, dark-colored urine, or extreme tiredness—as these could be signs of rare side effects.
Statins are still one of the best tools for preventing heart disease. Their effect on kidney health is still being explored, but most people can take them safely. If you’re worried about your kidneys and statins, talk to your doctor. Together, you can decide what’s best for your health.
