The many hazards of cholesterol

What is Cholesterol?

Cholesterol is a fat-like organic substance that is found in all cells in the human body. It is mainly produced in the body and helps in making of hormones, vitamin D, and substances that help digest foods. The body can also obtain cholesterol from outside products. These include animal sources, such as egg yolks, meat, and cheese which are rich in cholesterol.

Cholesterol is mainly found in two forms in the body – Low-density lipoprotein (LDL) which is unhealthy and High-density lipoprotein (HDL) which is the healthy kind. Cholesterol helps with many vital body functions but too much of it can cause serious damage to the body. Read on further to know its many risks and how you can maintain healthy cholesterol levels in the body.

Effects of Cholesterol

Nervous System

Cholesterol is an important constituent of the body as the body needs cholesterol for the brain to function efficiently. But too much cholesterol content in the body can cause problems. Too much cholesterol in the arteries can cause strokes which can damage parts of the brain. This could lead to loss of memory and motor functions and other severe neurological damages.

High cholesterol content has also been linked to brain damage in people with Alzheimer’s disease. It is important to maintain your cholesterol levels in the body and not let it go higher than the required limits. It is recommended for many to go for regular checkups at a clinic.

Cardiovascular and circulatory systems

Too much LDL cholesterol in the body can lead to its build up in the arteries which clogs them. The arteries will harden and blood flow is hampered. This causes the heart to work harder to push blood through them leading to plaque buildup which in turn could lead to high blood pressure and heart diseases.

Plaque buildup in coronary arteries can disrupt the flow of oxygen-rich blood to the heart which may cause chest pain known as angina. This is a sign that the person is at risk for a heart attack and it can be dangerous. Breaking of plaque pieces could lead to formation of clot which is harmful to the body. A heart attack and in some cases strokes can be caused when clots are formed and not treated.

When the menstrual cycle changes the hormones in the body undergo a huge change.

It is recommended for women reaching the age of menopause to take care of the cholesterol levels in their body and go for regular check ups at a clinic.
