It certainly won't help your health. It could induce diabetes. It could have a serious effect on your heart and it could cause a thrombosis which could cause a heart attack. A stroke is also a possibility. The answer is tat it is not certain to kill you but it could have a serious impact on your longevity.
High cholesterol is not a good sign for health.It depends how high,it is.More than 200 mg/dl is borderline risk,more than 250 mg/dl is high risk for heart attack.The desirable range is less than 200 mg/dl.
Cholesteral will not kill you. Kind of in the same way that a gun won't kill you. Cholesteral can clog up your arteries, improving the chances of a cerebral hemorrage or stroke.Likewise, it can clutter up the heart valves and eventually form a wall through which blood cells cannot get past. This equals a rather nasty heartattack in the short term, and if you don't die immediately, heart disease in the long term.
