Low LDL cholesterol probably isn't causing illnesses like cancer or depression — it's more likely that these diseases are lowering cholesterol as a side effect.

High cholesterol might not be the main reason for heart disease, and having too little cholesterol could actually be risky — so the old idea that cholesterol causes heart problems might not tell the whole story, especially for preventing heart issues in healthy people.

Getting cholesterol extremely low doesn’t seem to make people more likely to get cancer, stroke, diabetes, liver problems, muscle issues, or cataracts — at least not in the time frame studied.

People with higher levels of 'bad' cholesterol in their blood are more likely to have heart attacks or other heart problems.

Cardiovascular risk persists despite low LDL cholesterol levels if concomitant metabolic syndrome, hypertension, chronic inflammation, or dysglycemia remain unaddressed.

Taking strong cholesterol drugs to get LDL very low doesn’t make you more likely to develop type 2 diabetes than taking standard doses.
