LDL cholesterol – what do your numbers mean?
Have you had your LDL cholesterol level measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what a too high or too low level can mean, and when it makes sense to get tested.
What is the normal range for LDL cholesterol?
What is the normal range for LDL cholesterol?
The normal range for LDL cholesterol varies depending on the individual's health status and risk profile. For healthy adults, LDL cholesterol should be below 2.6 mmol/L. For patients with known ischemic heart disease, the target value is below 1.4 mmol/L, while for patients with type 2 diabetes it is below 1.8 mmol/L (and even below 1.4 mmol/L with concomitant organ damage or other very high risk). Pregnant women may experience increasing values, which can be up to 50% higher at birth. It is important to note that values close to the limits may indicate an increased risk of cardiovascular disease, and it is recommended to consult a doctor for further assessment.
What does a low level mean?
A low level of LDL cholesterol, typically below 1.0-1.5 mmol/L, rarely has clinical significance unless it occurs suddenly. Causes may include hyperthyroidism, certain types of cancer, or genetic factors. Symptoms are often not present, but if the level drops drastically, it may be a sign of an underlying condition requiring attention. Groups such as patients with hyperthyroidism or cancer may be particularly vulnerable. If one experiences a low LDL level, one should contact a doctor to rule out serious causes and ensure proper treatment.
What does a high level mean?
A high level of LDL cholesterol, above 2.6 mmol/L for healthy adults and even lower for at-risk groups, increases the risk of atherosclerosis and cardiovascular disease. Causes may include a high-fat diet, inactivity, genetic factors such as familial hypercholesterolemia, or diseases such as diabetes and hypothyroidism. Symptoms are often absent but can lead to serious complications such as heart attack or stroke. It is recommended to seek medical advice if you have elevated LDL cholesterol, to get an assessment and possibly start treatment with lifestyle changes or medication.
