What is a cholesterol test?

A “cholesterol test” is a type of blood test that determines the amount of cholesterol in the blood. Cholesterol is a waxy, fat-like substance produced by the liver and present in some foods.

There are several types of cholesterol, including low-density lipoprotein (LDL) cholesterol (often referred to as “bad” cholesterol), high-density lipoprotein (HDL) cholesterol (often referred to as “good” cholesterol), and triglycerides. The test can help determine a person’s risk of developing heart disease and other health problems. This test is also known as a lipid profile test.

Why is a cholesterol blood test recommended?

A lipid profile blood test is recommended to assess an individual’s risk of heart disease and other health problems related to high cholesterol levels.

A cholesterol test is typically recommended for:

1. Adults over the age of 20: A cholesterol test is recommended at least once every five years.
2. Individuals at increased risk of heart disease: people with high blood pressure, diabetes, smoking habits, a family history of heart disease, or those who are overweight may need to have their cholesterol levels checked more frequently.
3. Individuals who have already been diagnosed with high cholesterol: For these individuals, cholesterol levels should be checked regularly to monitor the effectiveness of any treatments prescribed by a doctor.

High levels of LDL cholesterol can contribute to the buildup of plaque in the arteries, which can increase the risk of heart attack, stroke, and other cardiovascular problems.

The test can help determine the levels of good (HDL) and bad (LDL) cholesterol and triglycerides, which are a type of fat in the blood. 

Based on the results, our healthcare providers can recommend lifestyle changes, such as dietary changes and increased physical activity, and/or prescribe medication to help manage cholesterol levels and reduce the risk of heart disease and related health problems.

What is the normal cholesterol level? 

The normal cholesterol levels are considered as:-

1. Total cholesterol: Less than 200 mg/dL is considered desirable for adults.
2. Low-density lipoprotein (LDL) cholesterol: less than 100 mg/dL is considered optimal. Levels between 130-159 mg/dL are considered borderline high, while levels of 160 mg/dL or higher are considered high.
3. High-density lipoprotein (HDL) cholesterol: More than 60 mg/dL is considered protective against heart disease. Levels less than 40 mg/dL are considered low.
4. Triglycerides: less than 150 mg/dL is considered normal. Levels between 150-199 mg/dL are considered borderline high, while levels of 200 mg/dL or higher are considered high.

What are LDL and HDL in a cholesterol blood test?

LDL and HDL are two types of cholesterol measured in a lipid profile test.

Low-density lipoprotein, or LDL, is known as “bad cholesterol” because it can cause the artery walls to harden with plaque, which raises the risk of heart attack and stroke.

HDL is a High-density lipoprotein and is referred to as “good cholesterol” because high levels of HDL cholesterol help to remove excess cholesterol from the bloodstream and transport it back to the liver for processing and elimination. High levels of HDL cholesterol are considered protective against heart disease.

What are the symptoms of high cholesterol?

High cholesterol generally does not have any symptoms. This is why it is often referred to as a “silent killer.” In many cases, high cholesterol levels can go unnoticed for years until they are detected through a routine cholesterol test.

In some cases, people with very high cholesterol levels may experience symptoms such as chest pain, shortness of breath, or an irregular heartbeat, but these symptoms are more commonly associated with other conditions such as heart disease or angina.

The best way to determine if you have high cholesterol is to get a cholesterol test from our healthcare provider. Regular cholesterol testing can help detect high cholesterol levels early, allowing for prompt treatment and reducing the risk of heart disease.

How do you manage your cholesterol?

You must consider the following factors when managing your cholesterol:

1. Diet

Eating a diet that is low in saturated fat, trans fat, and cholesterol can help lower cholesterol levels. This includes eating more fruits, vegetables, whole grains, and lean protein sources, and reducing the intake of high-fat foods such as red meat and full-fat dairy products.

2. Exercise

Regular physical activity, such as brisk walking, can help raise HDL (good) cholesterol levels and lower LDL (bad) cholesterol levels.

3. Weight management

Maintaining a healthy weight through diet and exercise can help lower cholesterol levels.

4. Avoid smoking

You have to avoid smoking. Smoking can lower HDL (good) cholesterol levels and increase the risk of heart disease.

5. Medications

If lifestyle changes alone are not enough to lower cholesterol levels, medications such as statins, bile acid sequestrants, niacin, and fabric acid derivatives may be prescribed by your doctor.
