My Cholesterol Is 215, HDL 63 And LDL 136 At

My cholesterol is 215, HDL 63 and LDL 136 at a very recent test along with BUN/CREAT ration of 22.78 and glucose of 103 and NCHC at 36.3 which were flagged at High as a result. I'm a 63 year-old-woman, this doesn't look good, do I need to be on some type of medication or will diet change make a difference for me. I have Type A blood.
