High Cholesterol In Diabetes – A Guide To Diabetes and High Cholesterol

Why Do Diabetics Get High Cholesterol?

For most people, eating a healthy, balanced diet and being physically active is enough to keep cholesterol levels healthy. But for people with diabetes, high cholesterol is often a common side effect of diabetes. A study in 2002 reported that diabetes seems to either increase the production of cholesterol in the body or reduce its absorption so that more of it stayed in the blood. In another study, they found that blood sugar, insulin, and cholesterol all interact with each other in the body and are affected by each other.

What Is Cholesterol?

Cholesterol is a waxy substance that is produced by the liver and also found in foods such as butter, red meat, and high-fat cheese. Cholesterol is found in the blood and is essential in our bodies for our cells to function and to make vitamin D and some hormones, it becomes a problem when it gets too high.

LDL (low-density lipoprotein) If there is too much LDL cholesterol in the blood, it can slowly build in the arteries, making them narrower.

HDL (high-density lipoprotein) It helps to remove excess cholesterol from the bloodstream and returns it to the liver where it is broken down and passed out of the body.

What Should My Cholesterol Levels Be?

  • 5mmol/L or less for healthy adults
  • 4mmol/L or less for those at high risk

  2. You have some great information here, Garry. Thankfully, no one in my family has diabetes, but I have a very dear friend who lost her husband last summer to diabetic complications. I know it can be managed and you are living proof.

      Hi Micheal, thank you for your comment. Yes, diabetes can be managed but it is so hard. Many diabetics myself included find it really hard to control, I am type 1 and in the 22 years that I have had diabetes, I can probably count on 1 hand how many times my Hb1c has been in the desired range. It’s a near impossibility.
