Hey people. I've just had a lot on my mind thanks to some recent events.

I'm a 20 year-old male, 5'5", about 114 pounds. I also exercise regularly, and have done so for the past 1.5 years, and I incorporate a lot of cardio into my workout. In April, my doctor checked my cholesterol and it came back as:

TC 246
HDL 53
LDL 169
And I don't know the Triglycerides number, but I'm sure you guys can calculate it somehow.

My doctor told me it was a little high, and that I need to see a nutritionist on how I can better my diet. Now, my diet had always been quite good, but I decided to take her advice anyway. So, I've since stuck to a stricter diet. Originally, it was very strict, but I've managed to loosen up a little, including fatty foods only on occasion so as not to lose out on essential nutrients. (That and I'm closing in on underweight for my height. Also, my mother, a doctor herself, thinks the test is wrong, and that my numbers are actually much lower. I've also upped the cardio in my workouts, so as to better the HDL.)

What do you think about my numbers and what I should do? (Please note that there has not been a history of high cholesterol on either side of my family.)

Now, on to what's on my mind.

Throughout my life, I've fainted more than the average person, about 6 times total. I thought I had fainted my last a couple of years ago, and I went to see a doctor about it. Judging from the tests he did, he came to the conclusion that I fainted because I had hypoglycemia in the morning hours, since my faints occurred during the morning. He also determined this because I usually had only cold cereal for breakfast, and recommended that I be given eggs for breakfast on most days to remedy this problem. Well, for a period of time, I followed his recommendation, but after a few months, I simply began eating what I like for breakfast, and thought my problem was gone. (From what I know, I don't have cardiac syncope, as my doctor does not suspect it.)

A couple of days ago, I woke up quickly to go to the bathroom. There, while standing and urinating, I began to feel nauseated, dizzy, and weak, and had to stop urinating and soon found myself collapsing toward the floor. I was unconscious for a few minutes, but upon waking, I was hyperventilating, my pants were wet, and the back of my head was also wet. I stayed there for a few minutes, and only when I felt better, I got up and told my parents and they helped me out.

Has my problem returned or did I faint because I simply got up too quickly?

My mom thinks I need to eat much more, especially since I'm a growing teenage male, and not worry so much about what I eat. For some reason also, I find that when I eat non-fatty meals, I feel somewhat weak, but when I eat fatty meals, I feel energized and ready to go. Could there be a reason for this?

Sorry for all this information, but I've really needed a lot of advice. I plan on asking my doctor, but first I thought I'd get some input from you guys.

Thank you.
