High cholesterol has no symptoms, so regular checkups at the doctor are very important. A blood test is the only way to detect high cholesterol.

What are the important components when testing cholesterol?

  • LDL Cholesterol – This is referred to as ‘bad’ cholesterol and is involved in forming blockages in the arteries
  • HDL Cholesterol – This is referred to as ‘good’ cholesterol
  • Triglycerides – These are the main form of fat stored in the body. Any food that isn’t used for energy immediately – such as carbohydrates, fat or protein – is also converted into triglycerides.
