Nothing dire. But All cause mortality is higher with cholesterol levels below 130 then it is if it is the levels are over 200. And stroke can go up with levels under 150.
Are you sure you are talking LDL? Really...the lower the better. Most studies have shown an LDL at 70 or lower you really will not accrue plaque. Did you mean to say your HDL is very low or maybe your total is very low?
