Controlling Cholesterol

‘Good’ and ‘bad’ cholesterol

Cholesterol cannot travel around the body on its own because it does not dissolve in water. Instead, it is carried in your blood by molecules called lipoproteins.
The two main lipoproteins are LDL and HDL
Bad Cholesterol: Low-density lipoprotein (LDL)
This carries cholesterol from your liver to the cells that need it. If there is too much cholesterol for the cells to use, this can cause a harmful build in the artery walls, leading to disease of the arteries restricting the flow of blood to your heart, brain and the rest of your body. It also increases the chance of a blood clot developing.
Good Cholesterol: High-density lipoprotein (HDL)
This carries cholesterol away from the cells and back to the liver, where it is either broken down or passed from the body as a waste product. The amount of cholesterol in the blood (including both LDL and HDL) can be measured with a blood test.
Normal cholesterol level : Blood cholesterol is measured in units called millimoles per litre of blood, often shortened to mmol/L. The government recommends that cholesterol levels should be less than 5mmol/L. In the UK, two out of three adults have a total cholesterol level of 5mmol/L or above. On average, men in England have a cholesterol level of 5.5mmol/L and women have a level of 5.6mmol/L. The UK population has one of the highest average cholesterol concentrations in the world.

There are many risk factors that can increase your chance of having heart problems or stroke if you have high cholesterol.

  • an unhealthy diet, obesity, alcohol or smoking (can be changed by altering your lifestyle)
  • having diabetes or high blood pressure (can be treated with medication)
  • having a family history of stroke or heart disease (cannot be changed)

Who is at risk and should be tested?

Anyone can have their blood cholesterol level tested, but it is particularly important to have it checked if:

  • You have been diagnosed with coronary heart disease, stroke or mini-stroke or you have leg artery disease.
  • You are over 40.
  • You have a family history of early cardiovascular disease (for example, if your father or brother developed heart disease or had a heart attack or stroke before the age of 55, or if your mother or sister had these conditions before the age of 65).
  • A close family member has a cholesterol-related condition, such as familial hypercholesterolaemia (inherited high cholesterol).
  • You are overweight or obese.
  • You have high blood pressure or diabetes.
  • You have another medical condition such as a kidney condition, an underactive thyroid gland or an inflamed pancreas (pancreatitis). These conditions can cause increased levels of cholesterol or triglycerides.

Assessing your risk:

This sample will be used to determine the amount of LDL (bad cholesterol), HDL (good cholesterol) and triglycerides (other fatty substances) in your blood. When assessing your risk of heart attack or stroke, your PHARMACIST may refer to your cholesterol ratio. This is your total cholesterol level divided by your level of HDL cholesterol. Cholesterol levels or cholesterol ratio should not be looked at on their own. A number of other factors should be taken into consideration when assessing your risk, including:

  • BMI (body mass index), which measures your weight in relation to your height.
  • Treatable risk factors, such as high blood pressure (hypertension), diabetes and other medical conditions.
  • Your age, sex, family history and ethnicity.

At the end of your assessment, you will be told whether you have a high, moderate of low risk of getting cardiovascular disease (heart disease or stroke) within the next 10 years. If you have been diagnosed with high cholesterol, the first method of treatment will usually involve making some changes to your diet (adopting a low-fat diet) and doing plenty of regular exercise. After a few months, if your cholesterol level has not dropped, you will usually be advised to take cholesterol-lowering medication.
