High Cholesterol Q & A

CardioHealth

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 — or H for happy — 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 — or L for lousy — LDL carries cholesterol throughout your body, where it builds up on the walls of your arteries and makes them narrow and hard.   

What causes high cholesterol?

Having high cholesterol means that Dr. Castello has diagnosed you with higher than normal levels of total (TC) cholesterol. For most people, high cholesterol is the result of unhealthy lifestyle choices combined with genetic factors that make them likely to develop the problem.

Smoking is one of the worst things you can do. Besides increasing your LDL cholesterol level, tobacco use also decreases your HDL.

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, hypothyroidism, and obesity, for example, are all associated with high cholesterol.

How is high cholesterol diagnosed?

The best 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

Unhealthy cholesterol levels are:

  • Total cholesterol levels above 200 mg/dL
  • LDL cholesterol levels above 190 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 medications, preferably statins.

The most current indications and guidelines to treat cholesterol are based on the percentage risk of developing coronary heart disease in 10 years, which depends on cholesterol levels and the presence or absence of clinical risk factors.

Four patient groups have been defined, each of which requires a distinct treatment method:

  1. Secondary prevention: This is treatment needed for patients with proven cardiovascular disease
  2. Primary prevention: Treatment before there is proven cardiovascular disease; statins are indicated if LDL is>190
  3. Primary prevention: Diabetes, aged between 40-75yrs with LDL between 70 and 189
  4. Primary prevention: No diabetes with a 10yr risk of cardiovascular disease >7.5% who are 40-75 yrs and LDL between 70-189
