High cholesterol is caused by an accumulation of low-density lipoprotein cholesterol from modifiable and non-modifiable risks, namely:
There are two types of cholesterol in the body:
Contrary to what most people think, not all cholesterol is harmful – as ‘bad’ as LDL is, we actually do need a certain amount of LDL in our bodies; and HDL is necessary to remove excess LDL from our bloodstream.
A high level of LDL cholesterol in the blood leads to buildup of cholesterol in the blood vessels (atherosclerosis). This can lead to health issues like cardiovascular risk as a buildup of cholesterol can narrow and limit blood flow to the heart. A complete cut off of blood supply can result in a heart attack.
There are often no symptoms of high cholesterol and many patients go undiagnosed for years. For this reason, high cholesterol is touted as a “silent killer”.
When symptoms appear, they are:
The only way to detect high cholesterol is through a blood test. If you’re unsure about whether you have high cholesterol, contact us to schedule a blood test and health screening to detect high cholesterol early.

High cholesterol is diagnosed during a blood test that includes a lipid profile to examine your risk of heart disease, blood pressure readings, and blood sugar (glucose) test to check for diabetes.
Diagnosis may also include checking your BMI (body mass index) and the types of fat present in your blood (triglycerides) to develop a treatment plan that is tailored to you.
For example, if you have been adopting a relatively healthy diet but still display high levels of cholesterol, you may in fact have a preexisting health condition such as diabetes, thyroid conditions (i.e. hypothyroidism) or liver disease that may be affecting your cholesterol levels.
The best way to manage high cholesterol is through:
Some patients might need medication alongside the aforementioned practices.
A good cholesterol management programme should have a trained doctor to advise you on the above to keep your total cholesterol levels as low as possible.
A person is at high risk of developing coronary artery disease if their total cholesterol level is between 5.2 and 6.1mmol/L.
Yes, high cholesterol can very much be managed with simple lifestyle changes such as exercise and eating a healthy diet. However, if your cholesterol levels still remain high despite making these changes, your doctor may recommend medication.
Studies suggest that coffee consumption is linked to higher cholesterol levels; although it is not the caffeine in coffee that affects cholesterol but the oils in the coffee bean.
