text: can anyone tell me how high cholesterol can go? my cholesterol is always around 250 or 260 and i am curious as to how high it can go on a person?  i would also like to know how high triglycerides can go on a person.  mine is usually 339.  i eat the right foods and i don't eat much meat, so i can'r understand this. high enough to kill you.  no, seriously...below is information on cholesterol from the american heart association...  your cholesterol level is a result of many things, one of which is diet...but your heredity can also play a big part.
