Cholesterol

Cholesterol testing is recommended for people who are at risk of developing heart disease or who have been diagnosed with high cholesterol or heart disease. The following groups of people may benefit from cholesterol testing:

1. Individuals with a family history of heart disease: If you have a family history of heart disease, you may be at increased risk and should discuss cholesterol testing with your healthcare provider.

2. People with high blood pressure: High blood pressure can increase the risk of developing heart disease, and cholesterol testing can help assess overall cardiovascular risk.

3. People who are overweight or obese: Being overweight or obese can increase the risk of developing high cholesterol and other health problems, so regular cholesterol testing is important.

4. People with diabetes: Diabetes can affect lipid metabolism and increase the risk of developing heart disease, so regular cholesterol testing is important for people with diabetes.

5. People who smoke: Smoking can damage the arteries and increase the risk of developing heart disease, making regular cholesterol testing important for smokers.

6. People over the age of 40: As people age, their risk of developing heart disease increases, making regular cholesterol testing important for people over the age of 40.

To help determine whether you should have regular cholesterol testing, it's important to discuss your individual cardiovascular health with your healthcare provider. By detecting high cholesterol early, healthcare providers can work with patients to develop a plan to manage their cholesterol levels and reduce their risk of developing heart disease.

Cholesterol is usually measured in milligrams (mg) of cholesterol per deciliter (dL) of blood. The following are general guidelines for interpreting cholesterol test results:

1. Total cholesterol: A total cholesterol level below 200 mg/dL is considered desirable, while levels between 200 and 239 mg/dL are considered borderline high. Levels above 240 mg/dL are considered high.

2. LDL cholesterol: LDL cholesterol is often referred to as "bad" cholesterol because it can contribute to the buildup of plaque in the arteries. A desirable LDL cholesterol level is less than 100 mg/dL, while levels between 100 and 129 mg/dL are considered near or above optimal. Levels between 130 and 159 mg/dL are borderline high, while levels between 160 and 189 mg/dL are high. Levels over 190 mg/dL are very high.

3. HDL Cholesterol: HDL cholesterol is often referred to as "good" cholesterol because it helps remove LDL cholesterol from the bloodstream. A desirable HDL cholesterol level is above 60 mg/dL, while levels below 40 mg/dL are considered low.

4. Triglycerides: Triglycerides are another type of fat found in the blood that can contribute to the buildup of plaque in the arteries. A desirable triglyceride level is less than 150 mg/dL, while levels between 150 and 199 mg/dL are borderline high. Levels between 200 and 499 mg/dL are high, while levels above 500 mg/dL are very high.

Again, it's important to note that these levels can vary depending on a person's individual health and risk factors for heart disease. Healthcare providers will consider a person's overall health when interpreting test results and determining whether further action is needed to manage cholesterol levels.

Low levels of LDL cholesterol and high levels of HDL cholesterol are generally good for heart health. If a person's cholesterol levels are out of the desired range, healthcare providers may recommend lifestyle changes, such as diet and exercise, or medications to help manage their cholesterol levels and reduce their risk of developing heart disease.
