Cholesterol is defined as a waxy alcohol, fat-like substance that occurs naturally in all areas of the human body. 100-200 mg/dL is considered as normal for the human beings. However it must be noted that total cholesterol counts below 180 mg/dl increase the risk for hemorrhagic stroke; below 180 cholesterol levels are inversely associated with risk. Total cholesterol counts above 200 mg/dl may be normal and healthy for some people, as the ratio of LDL to HDL cholesterol is considered a more important factor in prediction of disease risk. Women tend to benefit more from an increase in HDL rather than lowering of LDL, whereas men tend to benefit from a decrease in LDL when cholesterol abnormalities or heart disease risk factors exist.
