Your cholesterol level at 6.9 mmol/L is a bit too high. From the figure, it is most likely a total cholesterol reading. Cholesterol levels in blood can be further broken down into a number of components, the most important of which are low-density lipoprotein cholesterol (LDL-C) level and high-density lipoprotein cholesterol (HDL-C) level. Raised levels of LDL-C are associated with higher risk of coronary heart disease, while higher levels of HDL-C have a protective effect.

Doctors usually look at cholesterol levels with a number of factors to determine if the risk of disease is high and if treatment is needed in any particular patient. These factors include the age and sex of the patient, whether there is any history of coronary heart disease in immediate family members (especially when the onset is early in their life), whether the patient is a smoker, hypertensive or having diabetes mellitus. Your doctor will decide if you have any of these factors, and see if you need drug treatment to lower your blood cholesterol level.

Whether you are on drug or not, it is very important that you adopt healthy lifestyles. Eating a balanced diet, taking in more fresh vegetables and fruits and avoiding foods that are salty and fatty can surely help. In addition, regular exercise at least 30 minutes a day (like brisk walking, swimming, ball games) can also help lower the cholesterol level. Abstinence from cigarette and alcohol is also important.
