All About Hyperlipidemia Cholesterol

Hyperlipidemia is an elevation of lipids in the bloodstream. These lipids include cholesterol esters, cholesterol, triglycerides and estersphospholipids. In general, hyperlipidemia can be classified into two different types:

  • Hypercholesterolemia, where there is an excess amount of cholesterol
  • Hypertriglyceridemia, where there is an excess amount of triglycerides, the common form of fat

Description of hyperlipidemia:

Cholesterol or the fat-protein travels in the blood in packages is called lipoproteins. High density lipoprotein (HDL) and Low density lipoprotein (LDL) are the best known two lipoproteins. High level of LDL cholesterol leads to the clogging of arteries, which eventually results in heart diseases. Thus, the higher LDL cholesterol level you have, the higher is the risk of heart diseases.

Therefore, LDL cholesterol is also known as the bad cholesterol. Whereas, HDL cholesterol is called good cholesterol. The lower HDL cholesterol level you have, the higher chance you have of getting coronary heart disease. Low level of HDL cholesterol is normally accompanied by high levels of blood triglyceride, which increases the risk of coronary heart disease.

Risk factors and causes of hyperlipidemia

The most common causes of hypercholesterolemia are hypothyroidism (low thyroid hormone levels), kidney failure and pregnancy. Whereas, the common causes of hypertriglyceridesmia are diabetes, obesity, excess alcohol intake and certain medical prescriptions like estrogen and glucocorticoids.

Hyperlipidemia along with hypertension (high blood pressure), diabetes, smoking and any family history of the same are all main risk factors for heart diseases or coronary heart disease.

Symptoms of hyperlipidemia:

It doesn’t have noticeable symptoms. You can discover this condition during routine examination for atherosclerotic cardiovascular disease. Deposition of cholesterol may form under the skin mainly along the achilles tendon or around the eyes. Whereas, individuals with hypertriglycerides may have numerous pimple-like lesions on the skin. Extremely high triglyceride levels can also lead to pancreatitis.

Diagnosis of hyperlipidemia

: Diagnosis is generally based on physical examination, medical history and blood tests. Blood test can be done after overnight fasting to determine the specific HDL cholesterol, LDL cholesterol and triglyceride levels.
