Why do we have cholesterol?
Cholesterol is a lipoprotein that is used by our body as a building block for hormones, vitamin D and other substances. Cholesterol also helps with protection, insulation and signalling of nerve cells and repair of damaged arteries.
In the liver, cholesterol is converted to bile and bile salts. These bile salts are needed for the absorption vitamins including vitamin A, E and K.
What causes high cholesterol?
There are many reasons why you might have high cholesterol. As it is a building blog of hormones, hormone disruption can be one cause of high cholesterol. This could be anything from thyroid hormones and stress hormones to menopause and insomnia.
Inflammation is the most common cause of high cholesterol. Inflammation can be caused by eating a diet high in processed foods and low in fruit and vegetables. It may also be caused by food allergies and intolerances. Exposure to toxins, nutritional deficiencies, the use of certain kinds of medications, chronic stress, insufficient exercise, insufficient sleep, low grade infections, and gut imbalances can lead to inflammation.
Genetics play a factor. Some people produce more cholesterol and are genetically predisposed to have high cholesterol. As you make more cholesterol and your body cannot get rid of it quickly enough, your cholesterol is more likely to become a problem and develop in plaques which can lead to atherosclerosis, heart attacks and strokes.
One way this happens is through poor liver function. Your liver is capable of producing the cholesterol your body needs. It is also responsible for breaking down cholesterol and keeping it regulated. If through genetics, diet, alcohol consumption, medications or toxin exposure, your liver starts to under function you will most likely have high cholesterol.
