Almost 25 million adults within the U.S. have high cholesterol, which places them at a higher risk for a heart attack or stroke within the subsequent decade. However a a lot greater portion have what’s referred to as borderline excessive ldl cholesterol, an in-between place that’s not fairly excessive, however not fairly inside a traditional vary.
Right here’s what to learn about borderline ldl cholesterol.
What’s borderline ldl cholesterol?
Excessive ldl cholesterol is defined as having a complete ldl cholesterol variety of 240 mg/dL or above. Somebody has borderline ldl cholesterol, in the meantime, when their complete ldl cholesterol is within the 200 to 239 range.

There’s some flexibility: Some folks could also be utterly wholesome with a complete ldl cholesterol stage of 235, whereas others might be in danger at 205. It relies on an individual’s different danger components. However broadly talking, these thresholds assist medical doctors make selections about affected person care.

It is a tough categorization and never a assure of coronary heart issues to come back. “LDL-related ldl cholesterol danger is on a continuum—there isn’t a magic quantity above which you’re in danger and under which you aren’t,” Navar says. “The upper your LDL is and the longer your LDL is elevated, the extra danger you accumulate over time.”
