My LDL went up on my last 2 tests. It dropped steadily since diagnosis in 2014, test on test, then suddenly last June it shot up and in November went up a bit again. It is now 3.6, the highest it has been since diagnosis. I have no idea why it should suddenly happen after all this time. There have been no dietary changes. I am not at all concerned and even my DN told me it would be mostly "the big lorries" as she called it, meaning the big fluffy particles that cause no harm - because my trigs are low. (she had been on a cholesterol training session!)
