I am 30 yoa 5'11" weight about 260. cholesterol is 258. everything else normal. is alt of 51 high. could it be the cholesterol.

It might,,: This is only slightly elevated at most and could be from anything like having a alcohol recently to some fatty changes from eating too much to too much activity recently. That you're 5'11" and 260 means you're likely a little heavy and a cholesterol of 258 could mean fatty changes so see your doctor about a healthy diet and exercise to lower your weight and cholesterol. Good luck.
