Hypercholesterolemia may lead to hypertension, atherosclerosis and coronary artery disease. Symptoms will usually appear only in the advanced stage. Take lipid profile (Total cholesterol, LDL, HDL and Triglyceride)
Control your high cholesterol, if any, by diet and exercise. Some persons may have high cholesterol by familial heredity.
Adopt DASH diet. Eat a low-cholesterol, low-fat diet, which includes cottage cheese, fat-free milk, fish, vegetables, poultry, and egg whites. Use monounsaturated oils such as olive, peanut, and canola oils or polyunsaturated oils such as corn, safflower, soy, sunflower, cottonseed, and soybean oils. Avoid foods with excess fat in them such as meat (especially liver and fatty meat), egg yolks, whole milk, cream, butter, shortening, pastries, cakes, cookies, gravy, peanut butter, chocolate, olives, potato chips, coconut, cheese (other than cottage cheese), coconut oil, palm oil, and fried foods.

High cholesterol can be reversed, but I wouldn't support what you have in mind.

Cholesterol isn't just "that fatty, waxy stuff that accumulates in the blood". The body produces cholesterol for a reason.

When you don't drink enough water and the blood thickens, it also becomes toxic. Pumping this toxic blood through the arteries can cause minute tears and abrasions. The body then produces cholesterol to act as a bandage to protect the damaged areas until the repairs can be made.

However, you still run the risk of cholesterol build up or, if not enough cholesterol is produced, some of the damage can peel away and cause embolisms, and travel to the lungs or the brain.

You should eat properly and increase your water and salt intake. Too many people take their health for granted - they live for today, with no thought about tomorrow. But tomorrow always comes, and so do the consequences. Make a habit of taking care of your health while is easier. You may think it's not that easy now, but wait until you get older and your health starts to decline - THIS is when it gets difficult. You'll look back and say, "I wish....".

There's been a debate about that particular question, So.. I guess this question is left without a definite answer.

However, The damage caused by dyslipidemia can cause various complications which are not very favorable so I always recommend healthy diet & healthy lifestyle

If you work systematically (during all your lifetime and not periodically - 5 or 10 years), you may be far away of high cholesterol problems.

But if you eat rubbish, it will come a moment in which nothing would work to turn everything as it was before. Moreover, don't forget, age is another factor which contribute to high cholesterol problems. With the passing of years, your body metabolism will not be the same (reduced because of the age), and if you start to be healthy in this period of time, then it would be much more difficult.

Enjoy your precious life in a healthy way!
