Cholesterol levels are one of the determining factors of good health. Cholesterol is a fatty substance that can be found in animal tissues and is considered as an important component of the human body. It is manufactured in the liver and disseminated in the body through the blood. Food products that are high in cholesterol are meat, poultry, shellfish, and dairy products. Cholesterol has a good side and bad side and understanding them is essential for maintaining the body's proper functions.

Some cholesterol are essential in digesting fat from food, producing hormones, building cells, and for other physiological processes. Too much bad cholesterol, however, may raise the risk of having a heart attack or stroke. High cholesterol levels does not bring any obvious symptoms until it has caused serious damage including hampered blood flow due to hardened arteries. It is also responsible for the development of coronary artery disease, enlarged left heart, and heart failure. In addition to these ill effects, high cholesterol levels are also responsible for erectile dysfunction among men. There is no clear cause of high blood pressure but health experts suggest that smoking, having a high fat diet, excessive alcohol drinking and other factors may contribute to the development of this condition.

Individuals who are 20 years of age and above are encouraged talk to their doctors to see if their cholesterol levels need to be tested. For individuals with no risk factors, routine screening usually begins at the age of 40 for men and 50 for women. Female patients should be screened as soon as they stop having regular menstruation.

High cholesterol that cannot be lowered with exercise and diet can be treated with the use of statins. Statins are a class of drugs that are used to lower the body's bad cholesterol levels. They work by blocking a substance that the body needs to produce cholesterol. Statins may also work by reabsorbing cholesterol that has been stored in the plaques of the artery walls and prevent further blockage of the blood vessels. It is often prescribed by doctors to patients who have a history of heart attack and other health ailments are associated with high cholesterol levels. Statins include well-known medications such as lovastatin, simvastatin, atorvastatin, pravastatin, rosuvastatin, and others.

There are reports that some online drugstores deliver cheap but counterfeit drugs.
