I had my surgery just over a year ago ( about 14 months) I am 25 and before I had my surgery part of my reasoning for doing it was because my cholesterol was so dangerously high. I was excited to see in June (6 month bloodwork checkup) that my Cholesterol level had gone down alot (almost 100 points) Well I just got back my newest results and my Cholesterol has skyrocketed even higher than ever before. I have lost more than half my total body weight i am well in the normal rage for my bmi but my cholesterol is even higher now, how is this possible!? Im so angry, frusterated, and dissapointed in myself. My cholesterol is 389 and Ldl 317. I feel like as a 120lb 25 year old female this is unheard of.

Also, my bloodwork keeps coming back with my insulin level "less than 2.0" (normal range being between 6.0-27.0) the insulin was like this just before my surgery as well, both my surgeon and doctor brushed it off as a lab mistake but this is now the 3rd time my insulin is showing up as <2 my glucose level is normal and everything else is pretty normal. Is there anyone out there that has ever expierenced either an increase in cholesterol AFTER surgery or the extremely low insulin levels either before or after? I guess im just so confused and hoping someone on here can shed some light on what could possibly be going on.

It could be hereditary instead of dietary.

Right after surgery my LDL levels dropped to normal range. Now at a year past surgery my LDL levels have come back to just above normal. It is most likely hereditary causes. I am back on simvastatin at a lower dose than pre-surgery. Good news is that my HDL and triglycerides remain in the normal range and I am no longer type 2 diabetic.

I had a friend with cholesterol levels in the >300 range, and she was trim and fit. In her case it was genetic; her liver simply produced too much of the stuff (we make our own, since we need SOME cholesterol to live). You should talk to your doc about genetic causes and see if there's some kind of treatment.
