Cholesterol Q&A

Most of us will have heard of cholesterol, and that high cholesterol levels can be bad for our health. You may also have heard of good cholesterol and bad cholesterol, and perhaps that levels of each are affected by our lifestyle and diet. Yet many of us still don’t really understand what cholesterol actually is, what different levels can mean for our health, and how we can take action to lower our bad cholesterol and get more of the good stuff.

Cholesterol is a natural substance and all of us have cholesterol in our blood. We need both types to function – even the cholesterol that often gets labelled ‘bad’. Really, it’s not the substance itself that’s bad, but rather that we only need it in certain levels. Once our cholesterol levels get beyond a certain point, it can start to have negative effects on our health.

To understand it better, we spoke to consultant expert Dr Farhan Ahmed, who answers your questions about cholesterol and what it means to your health:

What is cholesterol and do I need to worry about it?

Cholesterol is an essential part of our body’s make-up and is found in every single cell of the body. We need it to aid the production of hormones and to coat and protect our cells.

However, it is possible to have too much cholesterol in our blood. Getting the balance right is very important.

Too much cholesterol can cause blood clots and block your blood vessels, which can increase your risk of heart disease, stroke and vascular dementia.

What about good cholesterol?

You may have heard people talking about 'good' and 'bad' cholesterol. High-density lipoprotein (HDL) is known as good cholesterol because it helps to remove Low-density lipoprotein (LDL), which is what is meant by bad cholesterol.

What are normal cholesterol levels?

A healthy cholesterol level is normally defined as 5 or below overall, with LDL at 3 or below and HDL at one or above. A cholesterol test can assess your total levels as well as your levels of HDL and LDL.

Who is most at risk from high cholesterol?

Most cases are due to lifestyle factors, but there are some groups who are more at risk than others.

If you have a family history of high cholesterol, early heart attacks or stroke, then it’s worth getting your levels checked as it can be hereditary. This is sometimes due to a condition called familial hypercholesterolemia.

People from South Asian backgrounds have also been found to be at higher risks compared to other groups. Other risk factors include gender, as men tend to develop heart disease earlier than females, and age. The older you get, the higher the risk of heart disease becomes. It's very important to keep an eye on both your HDL and LDL levels as you get older.

What are the symptoms of high cholesterol?

In general, there are no obvious symptoms.

In rare cases, people experience severe abdominal pain and a skin rash, but this is highly unusual. A blood test is the best way to measure levels.

If you are worried you may have high cholesterol levels and have not yet been tested, speak to your doctor about testing the levels of cholesterol in your blood.
