I recently got some bloodwork done. Just turned 25.
Total cholesterol was above 11mmol/l LDL cholesterol was above 9mmol/l HDL was 1.41 mmol/L Triglycerides were 1.06 mmol/L
Background: for the past 2-3 weeks I've been dieting with a fairly big deficit, around 1000 calories per day. So I've been eating fairly high protein as a percent of macros. Trying to get around 190 grams per day (I'm around 198lbs, six pack)
Anyway, my (calculated) LDL is too high. If it was just kinda high like you guys post sometimes I'd be okay with it. But it is super high.
Wonder if this factors in to the acute pancreatitis I suffered a few months ago. Maybe high cholesterol contributed to some very small gallstone which blocked the pancreatic duct. No idea.
Yes, I'm going back for measure of the different LDL particles when I can. Still I think the number is abnormally high and may have something to do with the liver not uptaking or excreting excess cholesterol.
Edit: Conversion of LDL into ng/dl is 357.
Hyperlipidemia -- lipid levels in the blood -- during caloric restriction could be part of the issue. As you burn fat, and release it into your blood stream cholesterol tests can show an increased LDL and HDL (and thus total cholesterol) while dropping Triglycerides.
Check with your doctor, make sure he/she knows about the weight loss. Ask if you should plateau before getting tested again.
I think this is just jumping the gun. You're on a highly calorie restricted diet and consuming an ass-ton of protein (which, for hardcore dieting is the right way to go - not arguing). You then get some blood markers checked and you're out of whack (although really high).
Get rechecked 3 months after you're done dieting and on something "normal" (whatever you decide normal to be).
Your cholesterol is very high. That't elevated enough that I doubt its entirely your diet. A few things that I'm pretty sure it isnt:
Its not a result of your dietary transition, as CD suggested. "...during caloric restriction could be part of the issue. As you burn fat, and release it into your blood stream cholesterol tests can show an increased LDL and HDL (and thus total cholesterol) while dropping Triglycerides..." I have never heard of anything like this.
If your TSH levels are normal, I'd stop chasing after hyperthyroidism: its not likely to be your culprit.
Bryan, you are correct that dieting - especially low carb - typically lowers LDL and raises HDL. When you had your lipid panel done, were you fasting? If so, for how long? If you ate or drank anything that can affect your lipid levels dramatically.
"..Wonder if this factors in to the acute pancreatitis I suffered a few months ago. Maybe high cholesterol contributed to some very small gallstone which blocked the pancreatic duct. No idea..." I highly doubt the two are related, so rest easy on that front.
A bit about me: My wife is a nurse and I'm a nursing student (graduating in May of 2013) so we're both pretty familiar with lipid panels and the lab work you had done. I researched a lot on the pathophysiology of low carb dieting and on endocrinology, and I've been a paleo eater for about a year and a half, closing on 2 years now.
If you're going back to get NMR or VAP, also get all your thyroid hormones checked. TSH, T4, T3, rT3, etc. Elevated cholesterol can be a symptom of hypothyroidism, which some people have symptoms of on a low carb diet. Check out all of Chris Kresser's posts on the subject.
If it's not thyroid, the next most likely explanation is familial hypercholesterolemia.
