High Cholesterol Q & A


What is cholesterol?

Cholesterol is an essential substance that your body uses to produce healthy cells. The waxy material is also present in the fats that circulate in your blood. The two different types of cholesterol that flow freely in your blood are categorized by how they behave:

High-Density Lipoprotein (HDL)

Also known as “good” cholesterol, HDL cholesterol picks up excess blood cholesterol and carries it back to your liver for processing.

Low-Density Lipoprotein (LDL)

Also known as “bad” cholesterol, LDL carries cholesterol throughout your body, where it builds up on the walls of your arteries and makes them hard and inflexible.   

What causes high cholesterol?

Having high cholesterol means that Dr. Castello has consistently diagnosed you with higher than normal levels of LDL, or bad, cholesterol. For most people, high cholesterol is the result of unhealthy lifestyle choices combined with genetic factors that make them prone to developing the problem.

Smoking is one of the worst things you can do. Besides increasing your LDL cholesterol level, tobacco use also decreases your HDL, or good cholesterol levels. Eating a diet that’s high in saturated fats or trans fats can increase your LDL cholesterol levels, while leading a sedentary lifestyle can decrease your HDL cholesterol levels.

If high cholesterol runs in your family, you may carry a genetic mutation that makes it harder for your body to clear LDL cholesterol from your blood.

For some people, certain medical conditions may contribute to the problem — kidney disease, diabetes, hyperthyroidism, and obesity are all associated with high cholesterol.

How is high cholesterol diagnosed?

Because there are no outward signs or symptoms of high cholesterol, the only way to diagnose it is by having a blood test. Your cholesterol levels are assessed with a lipid panel, which is a fasting blood test that requires you to avoid all food and liquids, other than water, for at least nine hours before your blood is drawn.

Healthy cholesterol levels are:

  • Total cholesterol levels below 200 mg/dL
  • LDL cholesterol levels below 100 mg/dL
  • HDL cholesterol levels above 60 mg/dL

For people with heart disease or diabetes, the desirable range for LDL cholesterol is below 70 mg/dL.

Unhealthy cholesterol levels are:

  • Total cholesterol levels above 240 mg/dL
  • LDL cholesterol levels above 160 mg/dL
  • HDL cholesterol levels below 40 mg/dL for men, and 50 mg/dL for women

How is high cholesterol treated?

High cholesterol is a highly treatable problem that usually responds well to a combination of lifestyle changes and medication.

If your cholesterol levels aren’t too high, or if you don’t have other risk factors for heart disease, such as high blood pressure, you may be able to focus on lifestyle adjustments first to see if you can reduce your cholesterol levels without medication.  

This includes following a nutritious, whole-foods based diet that’s low in total fat, saturated fat, and added sugars. Other beneficial lifestyle changes include quitting smoking, managing your stress levels, increasing your physical activity, and losing weight, if necessary.

If your cholesterol levels are dangerously high, or if your body doesn’t respond to lifestyle interventions quickly enough, Dr. Castello may recommend medication.

Statins, which Dr. Castello might prescribe alongside bile acid-binding resins, can help lower LDL cholesterol levels. Cholesterol absorption inhibitors help reduce the amount of cholesterol you absorb from your diet, while injectable medications prompt your liver to absorb more LDL cholesterol.
