How can I lower my ldl and raise my hdl?

Surgery is not the treatment for high cholesterol. Medication is one treatment. Cholesterol comes from heredity and lifestyle. One you can do something about, the other you cannot. If you always eat low saturated fat foods and exercise regularly, you have conquered the lifestyle portion of the equation. There is nothing you can do about your heredity. If the lifestyle changes have not lowered your numbers adequately, you must resort to medication. The alternative is heart and circulatory disease, causing heart attack and stroke. Please re-evaluate your stance on the statins that can lower your numbers to an acceptable level.
