Statins help millions manage their cholesterol and reduce the risk of heart attack and stroke. But like all medications, they come with potential side effects—some more surprising than others.
Here’s what recent findings reveal about the downsides you need to be aware of.
Muscle Pain Isn’t Just In Your Head

Aching thighs or stiff shoulders? Muscle discomfort is one of the most common complaints among statin users.
While some studies say up to a third of users report it, the numbers vary depending on the type and dose—and your mindset may matter more than you think.

Statins Can Raise Blood Sugar

These medications may quietly interfere with insulin, nudging blood sugar levels higher. A Dutch study found that statin users aged 55–75 had a notably increased risk of developing type 2 diabetes.
The risk is still considered small, but it's real—especially for those already on the edge.
A Rare But Serious Condition: Rhabdomyolysis

While extremely rare, a severe reaction called rhabdomyolysis can break down muscle tissue and flood the bloodstream with harmful proteins.
Watch out for extreme fatigue, unusual muscle pain, and dark urine—it might be more than just a bad workout.

Gut Reactions Can Happen

Some patients report nausea, bloating, or other stomach issues after starting statins. While usually mild and short-lived, digestive trouble can be enough to make someone stop taking the drug altogether. Talking to your doctor can help tweak the dose or timing.
Headaches Might Follow

Headaches aren’t the most talked-about side effect of statins, but they’re on the list. Though not dangerous, recurring headaches may affect your daily life and lead to reduced adherence to treatment plans.
Liver Values Can Spike

In rare cases, statins can cause elevated liver enzymes, a sign your liver is working overtime.
Regular blood tests during treatment help catch any issues early—most of the time, the body adjusts without major problems.

Weight Gain Could Be Indirect

Surprisingly, some statin users report gaining weight—not because the drugs cause it directly, but because people may become more relaxed about their diet, trusting the pills to do all the work. Statins aren’t a substitute for healthy habits.
Psychological Impact Plays A Role

Some patients experience side effects not from the drug itself, but from the expectation of them—a phenomenon known as the nocebo effect.
Simply fearing muscle pain can make it feel real, which shows how powerful the mind-body link can be.
Risk Vs. Benefit Depends On The Patient

While side effects can be concerning, they must be balanced against the benefits—especially for those with a high risk of heart disease.

Lifestyle Still Matters

Relying on statins without changing diet, exercise, or smoking habits is a missed opportunity.
Combining medication with healthier living gives the best long-term results—and might allow for lower doses with fewer side effects.
