Understanding Cholesterol: What it is and Why it Matters

Understanding Cholesterol

for Health

Cholesterol is an essential fatty substance produced in the body, necessary for the formation of cell membranes and hormones. It is also present in food, mainly of animal origin. High blood cholesterol levels can increase the risk of serious medical conditions including heart attack and stroke. Understanding the role of cholesterol in the body can help you make informed decisions about what types of changes you should make to your diet and lifestyle to maintain healthy cholesterol levels.

What is Cholesterol?

Cholesterol is a type of lipid (fat) which is produced naturally by the body. It is an important part of every cell in the body and is used to create hormones and localized cell membranes. It is found in the blood stream and is carried through the body by the proteins lipid-carrying molecules called lipoproteins.

Types of Cholesterol

There are two main types of cholesterol found in the body; Low-density lipoprotein (LDL) and High-density lipoprotein (HDL). LDL is considered to be “bad” cholesterol because it can build up in the arteries, narrowing them and increasing the risk of heart attack and stroke. HDL, on the other hand, is “good” cholesterol as it helps to remove the bad LDL cholesterol from the bloodstream.

Causes of High Cholesterol

High blood cholesterol can be caused by a variety of lifestyle factors, including diet and physical activity. Eating a diet high in saturated fat and cholesterol can cause an increase in LDL cholesterol. Similarly, being overweight or obese can result in elevated blood cholesterol levels. Lack of physical activity can also increase LDL cholesterol levels.

Risks of High Cholesterol

If left untreated, high cholesterol can lead to serious health issues such as heart attack and stroke. A buildup of cholesterol in the arteries can restrict blood flow, leading to high blood pressure and an increased risk of cardiac arrest. High cholesterol can also cause the buildup of plaque in the arteries, which can further narrow the arteries and increase the risk of heart attack or stroke.

Reducing Cholesterol Levels

Making lifestyle changes is the best way to lower cholesterol levels. Eating a diet low in saturated fats, trans fats, and cholesterol can reduce cholesterol levels and reduce your risk of heart disease and stroke. Exercise at least 30 minutes a day and maintaining a healthy weight can also help to keep cholesterol levels in check. In some cases, medications may be prescribed to help reduce cholesterol levels.
