Help!
I've been having the hardest time for the past two months. I went to a dermotolgist because my hair has been falling out. And when I went in for my annual check up my cholesterol is high. I don't really know what to do? And trying to understanding the numbers and their definitions for the HDL and LDL.
HDL=240
LDL=158
Triglycerides=91
Ratio for HDL=3.8

My blood pressure is always low ie. 100/70
And all I have been craving is sweet things. I am having a hard time getting back on the low carb and if I should try to help in modifying it to lower my HDL.
