Cholesterol is present in every cell of the body and has vital natural functions. It is produced by the body but can also be accumulated by food; and appears like a waxy fatty substance. Since cholesterol is oil-based it does not get mixed with blood, and as a result it is carried around the body in the blood by lipoproteins (which are the lipid on the inside and proteins on the outside). There two kinds of lipoproteins which carry cholesterol in the entire body – low-density lipoproteins (LDL) and high-density lipoproteins (HDL). LDL cholesterol is many a time called as bad cholesterol. A high level of LDL results is a buildup of cholesterol in the arteries. On the other hand HDL cholesterol is referred as good cholesterol, since it carries cholesterol from several parts of the body back to the liver, where the liver removes the cholesterol from the body. When there are high levels of cholesterol detected in the blood, the doctors will suggest alterations in the daily diet such as no Trans fat, less saturated fat along with some exercises. However, in spite of all that if the cholesterol levels (LDL) do not reduce doctors prescribe cholesterol-lowering drug to the patients along with the previously mentioned changes in the diet.
A study report on cholesterol-lowering drug market states that there are several medications which can lower blood cholesterol levels. Statins are suggested for most patients since they are the sole cholesterol lowering drug which has been directly linked with less risk for heart attack and stroke. Healthcare professionals might recommend other medications as well, particularly if a patient has some grave side effects and/or does not respond well to statin therapy alone. The detailed in-depth guidelines promote individuals to talk to their doctors about the risks and benefits of statin therapy if the patients fall into any of the following groups:
- Individuals with an inherited cardiovascular event (stroke, heart attack, peripheral artery disease, coronary or other arterial revascularization, transient ischemic attack, or stable or unstable angina)
- People with LDL cholesterol of 70 to 189 mg/dL and a 7.5% or higher dangers of acquiring a heart attack or stroke within 10 years.
- Diabetic people having LDL cholesterol of 70-189 mg/dL and who are in between 40 to 75 years old
- 21 years of age and older who have quite high level of LDL cholesterol
