What are normal cholesterol levels?




The amount of cholesterol in human blood can vary from 3.6 mmol/liter to 7.8 mmol/liter. The National Health Service (NHS), UK, says that any reading over 6 mmol/liter is high, and will significantly raise the risk of arterial disease. The UK Department of Health recommends a target cholesterol level of under 5 mmo/liter. Unfortunately, two-thirds of all UK adults have a total cholesterol level of at least five (average men 5.5, average women 5.6).

Below is a list of cholesterol levels and how most doctors would categorize them in mg/dl (milligrams/deciliter) and 5mmol/liter (millimoles/liter).

    Desirable - Less than 200 mg/dL
    Bordeline high - 200 to 239 mg/dL
    High - 240 mg/dL and above

    Optimum level: less than 5mmol/liter
    Mildly high cholesterol level: between 5 to 6.4mmol/liter
    Moderately high cholesterol level: between 6.5 to 7.8mmol/liter
    Very high cholesterol level: above 7.8mmol/liter
