What is High Cholesterol?

Cholesterol is a type of fat that is highly abundant in animal products such as red meat including burgers, steak, and sausage.  The Western diet is generally high in foods that contain cholesterol.  Over time, cholesterol and other fat begin accumulating in our blood stream and is known as a condition called hypercholesterolemia.  There is good cholesterol and bad cholesterol in our blood.  Good cholesterol is called HDL and bad cholesterol is named LDL.

Bad cholesterol (LDL) eventually makes its way to arteries all over our body.  This leads to arterial injury, inflammation, and eventually the development of fatty arterial plaques (atheromas).

Fatty plaques reduce blood flow to organs and tissues in our body, which reduces oxygen levels to these areas.  Fatty plaques can also abruptly rupture, leading to complete blockage of arterial blood flow and lack of oxygen delivery to tissues causing tissues to die.  When this occurs in the heart, it is called a heart attack.  This process can also happen in the brain, kidneys, gut, and limbs.

Since elevated cholesterol (hypercholesterolemia) has serious complications, it is important that patients understand its causes, symptoms, and treatment.

What Causes High Cholesterol?

High cholesterol is caused by diets high in fat and sugar.  Foods that are high in cholesterol include:

  • Red meats (e.g. steak, burgers, sausage)
  • Dairy – Milk, Cheese, Ice cream
  • Eggs

Some people have a genetic predisposition to developing various forms of elevated cholesterol, which is why hyperlipidemia tends to run in families.

How Common is High Cholesterol?

Hyperlipidemia is a highly prevalent condition in the United States.  It is frequently seen in the elderly population but can also affect adolescents and adults.  This is largely due to the Western diet and lifestyle – physical inactivity and little exercise.  The biggest concern is that hyperlipidemia is a major risk factor for cardiovascular disease, including heart attack and stroke, which are two of the leading causes of death in America.

Signs and Symptoms

 The symptoms and signs can range from no symptoms at all, to manifestations of its complications such as heart attack and stroke.  Patients are often asymptomatic in early cases that are mild.  Those with extremely high levels for long periods of time may eventually show signs of it on their face.  They often develop fatty plaque-like structures around the eye, which are called cholestomas. 

People with heart attacks usually have chest pain, difficulty breathing, nausea, and sweating.  Individuals with stroke develop sudden one-sided weakness or numbness, confusion, trouble speaking or swallowing, and headaches.  Patients with hypercholesterolemia are also at risk of developing peripheral vascular disease, which causes leg and calf cramps after walking certain distances due to poor circulation.


Your doctor will test for elevated cholesterol by ordering a fasting lipid panel.  Lipids are fats – a lipid panel tells your doctor which types of fats are elevated, normal, or low.  Remember – HDL is good cholesterol and LDL is bad cholesterol.  A high LDL is worrisome but a low HDL can also be concerning.

HDL is a good fat because it helps get rid of LDL and other bad cholesterol from our arteries, which helps reverse fatty plaque buildup in our arteries.  The fasting lipid panel also evaluates for other types of fat in the blood such as triglycerides – these can also be important in heart disease.  Statins are a class of medication frequently used to decrease cholesterol. They work by decreasing LDL, increasing HDL, and reducing triglycerides.

Your doctor will also likely order blood tests such as a CMP (comprehensive metabolic panel), and screen you for diabetes.  If your doctor is worried about a prior stroke or heart attack, they will probably obtain an EKG (electrocardiogram), chest x-ray, and ultrasound of the heart (echocardiogram).

Cholesterol Medication and Treatment

High cholesterol is treated with dietary and lifestyle changes, as well as medications.  Your doctor will likely recommend a low-sodium, low-cholesterol diet, rich in fruits and vegetables.  They may also tell you to avoid red meat and encourage intake of lean meats such as poultry and fish.

Your doctor typically evaluates for other cardiovascular risk factors such as older age, smoking history, diabetes, history of stroke or heart attack.  If you smoke, they will advise tobacco cessation.

They may recommend treatment with cholesterol-lowering drugs depending on your cardiovascular risk.  The most common prescription for elevated cholesterol is a class of medications called statins, which include:
