What does a high cholesterol level in the blood mean?

A high level of cholesterol in the blood, called hypercholesterolemia, is a sign of a metabolic problem. It can be due to an unhealthy lifestyle (unbalanced diet, sedentary lifestyle, lack of exercise) or an excessive production of cholesterol in the liver.

Cholesterol in the blood is used as a cardiovascular risk factor. Cholesterol level estimates the possibility of suffering a cardiovascular disease (heart attack, stroke, etc.). The higher the cholesterol level in the blood the higher the possibility to suffer a cardiovascular disorder. The possibility increases if there are additional cardiovascular risks (overweight, smoking, high blood pressure, etc.).

Cholesterol values are usually given in mg/dl but sometimes you can see those values in mmol/l following the International System of Units (SI). In case your values are in mmol/l you can convert them using this tool:

mmol/l
  • Mild hypercholesterolemia (200 - 240 mg/dl in adults):

    Cholesterol in the blood is a bit high but for the moment, it is not a matter for concern.

    In people at low cardiovascular risk, it is advisable to practice regular exercise and keep a balanced diet. It is recommended to monitor the cholesterol level every 6 to 12 months.

    In people at high cardiovascular risk (with previous heart attacks or strokes), it should be considered if taking medication to reduce cholesterol (statins) is appropriate.

  • Moderate hypercholesterolemia (240 - 300 mg/dl in adults):

    Moderate hypercholesterolemia requires follow-up.

    In people at low cardiovascular risk and with less than two cardiovascular risk factors (obesity, smoking, high blood pressure, diabetes, sedentary lifestyle) only diet and regular exercise is required. In case of more than two cardiovascular risk factors, medication should be added.

    In people at high cardiovascular risk (with previous cardiovascular problems), medication is needed.

  • Marked hypercholesterolemia (300 - 400 mg/dl in adults):

    Cholesterol level is too high and requires regular follow-up.

    In people at low cardiovascular risk (no smoking, no obesity, no diabetes and no high blood pressure), it is recommended to follow a strict diet and take regular exercise.

    In people at high cardiovascular risk, it is advisable to add pharmacological treatment, with potent cholesterol-lowering drugs.

    It is recommended to monitor the cholesterol level frequently (every 3 to 6 months).

  • Severe hypercholesterolemia (> 400 mg/dl in adults):

    Severe hypercholesterolemia is associated generally with genetic disorders. There is usually a family history of cardiovascular diseases at an early age.

    You should keep an exhaustive follow-up and regular monitor in lipid metabolism units. The risk of suffering a cardiovascular disease (heart attack, stroke, angina pectoris, etc.) at an early age is very high.

    The treatment is to follow a strict diet and take potent cholesterol-lowering drugs.
