Buddy of mine (mid-30's, male, recent ex-smoker, 6ft, 195 lbs) has come back with triglyceride numbers between 400 and 700 (yes he was fasting and has had these tests repeated several times). This was for a cholesterol test - apparently with triglyceride levels that high the HDL and LDL numbers are not trust-worthy? Anyways, he's on a diet of reduced (or no) sugar, cola, juices, red meat, and with a daily dose of flax seed for a few months before another test. No symptoms of diabetes that I'm aware of. He's vauguely aware that his brother also may have either high cholseterol or triglycerides. Sister, mother test ok. Father died in his 50's (heart disease of some sort). Anyways, I was wondering what other tests would be worth-while (say, thyroid?). Say that because of this diet his triglyceride levels test normal and so do the cholsterol levels. If this happens, and if he goes back to his normal diet, then presumably his triglyceride levels will go back up. If they do, is it a given that his cholsterol will also shoot up? OR, if the only consequence of an uncontrolled diet is high tryglycerides (but normal cholsterol) then is that a bad thing? Are there any medications that can reduce tryglceride levels? Please post any responses. Thanx.
