What is Cholesterol?

Cholesterol is a fatty substance that naturally exists in the body and plays an important role in maintaining health. It helps form cell membranes so that cells can function properly.

In addition, cholesterol is needed by the body to produce several essential substances, such as vitamin D, steroid hormones, and sex hormones including testosterone, estrogen, and progesterone. Cholesterol is also a component of bile salts that help the digestive process by aiding the absorption of fat soluble vitamins, namely vitamins A, D, E, and K.

Cholesterol cannot dissolve in the blood, so it is transported by special particles called lipoproteins. Lipoproteins are particles made of a combination of fats and proteins.

Cholesterol and triglycerides are two types of fats found in lipoproteins. There are five main types of lipoproteins: HDL (high density lipoprotein), LDL (low density lipoprotein), VLDL (very low density lipoproteins), IDL (intermediate density lipoproteins), and chylomicrons.

HDL is often referred to as “good cholesterol” because it helps carry cholesterol away from different parts of the body. In contrast, LDL is known as “bad cholesterol.”

What Happens When Cholesterol Levels Are Too High?

Although cholesterol is necessary for the body, excessively high levels can lead to health problems. One common issue is an increase in LDL cholesterol levels. When LDL levels become too high, they can increase the risk of plaque formation in the blood vessels.

The process of plaque formation begins when the inner lining of blood vessels becomes damaged, allowing LDL to enter and become trapped in the vessel wall. The LDL then undergoes changes and is consumed by immune cells called macrophages, forming what are known as foam cells.

The accumulation of these foam cells marks the beginning of plaque formation in the blood vessels. Over time, this plaque can narrow the blood vessels and lead to various health problems, such as coronary heart disease, stroke, and other cardiovascular conditions.

Symptoms of High Cholesterol

High cholesterol often does not cause clear symptoms, which is why it is commonly referred to as a silent condition. Many people only discover that they have high cholesterol after a blood test or when complications have already developed.

However, some individuals may experience symptoms such as pain in the neck or shoulders, fatigue, tingling in the hands or feet, dizziness, and headaches. Certain physical signs may also appear in some cases, including small yellowish lumps under the skin, yellow patches around the eyelids, and a white ring around the cornea of the eye.

What Are Normal Cholesterol Levels?

Normal cholesterol levels can vary depending on age, ethnicity, and sex. However, in general, the recommended cholesterol levels are as follows:

• Total cholesterol: below 200 mg/dL
• LDL cholesterol: below 100 mg/dL
• VLDL cholesterol: below 30 mg/dL
• HDL cholesterol: 40–80 mg/dL (men), 50–80 mg/dL (women)

How to Control High Cholesterol

High cholesterol can be managed by adopting a healthy lifestyle. One of the main steps is maintaining a healthy diet by reducing foods high in saturated fats and increasing the intake of vegetables, fruits, and fiber rich foods.

Regular physical activity, such as walking, cycling, or light exercise, can also help increase HDL levels (good cholesterol). Quitting smoking and maintaining a healthy body weight are also important for protecting heart and blood vessel health.

In some cases, lifestyle changes alone may not be sufficient to lower cholesterol levels. When this occurs, doctors may prescribe cholesterol-lowering medications such as statins. If statins are not effective, other medications may be used, including ezetimibe, fibrates, and bempedoic acid. There are also injectable medications available, such as alirocumab, evolocumab, and inclisiran.

Start Managing Your Cholesterol Before It’s Too Late
