Our liver naturally "makes" cholesterol for body functions, however, when we consume additional cholesterol, from our diet, it increases in the blood. If a person is lowering all the fats in their diet (as you seem to be by your question information) and the blood levels do not decrease, then it is recommended to go on Cholesterol lowering medication. You stated cholesterol medication does not agree with you. There are numerous types of medication that lower cholesterol via different mechanisms in the body. Hopefully you are able to tolerate one type. Best of luck.
