Statins: what they actually do, and the myths that stop people taking them

A statin lowers LDL cholesterol by slowing how much your liver makes, rather than by removing what's already stuck in your arteries. Taken consistently, it measurably lowers the risk of heart attack and stroke in people whose overall cardiovascular risk is high enough to warrant it, one of the largest, most repeated findings in modern medicine.

Serious liver injury from statins is rare; most people never need to stop for it, which is why a doctor checks liver function before starting and periodically after, not because harm is expected, but because checking is cheap and reassuring. Weigh that small, monitored risk against an unmonitored heart attack.

Muscle aches are the complaint people raise most, and they are real for some people. But controlled studies that compare a statin against a fake pill find most reported muscle pain happens on the fake pill too, meaning expectation plays a large role. If aches do appear, a doctor can usually solve it by switching statins or adjusting dose rather than stopping treatment altogether.

For someone whose doctor has assessed real cardiovascular risk and recommended a statin, stopping it quietly, without a conversation, removes one of the best-proven protections against a heart attack or stroke you can have. If side effects are genuinely bothering you, that is a reason to call your doctor, not to simply stop; there is almost always another option.
