A cholesterol level of 6.5 mmol/L is considered very high. Your doctor will also look at ratios of your good and bad cholesterol and whether you have any risk factors of heart disease.

Cholesterol is a fat produced by the cells in the body and obtained from animal-based foods. Though it has a bad reputation, cholesterol is required for many body functions, including developing cell membranes, producing certain hormones, such as estrogen and progesterone, and producing vitamin D. It also helps the liver produce bile acids that help the body absorb fats during digestion. There are four types of cholesterol:

  1. Total cholesterol
  2. High-density lipoprotein or good cholesterol
  3. Low-density lipoprotein or bad cholesterol
  4. Very-low-density lipoproteins or triglycerides

What are normal cholesterol levels?

Normal total cholesterol levels are as follows:

  • Healthy adults: Less than or equal to 5 mmol/L
  • High-risk individuals: Less than or equal to 4 mmol/L
