I agree. I have congentially high lipids. I've been trying for literally years to get my numbers down, with and without drugs. Last spring I hit an all-time high of 497.Critical mass. I was already taking Niaspan, specifically for triglycerides and my doctor doubled that.
With high triglycerides comes the high risk of type 2 diabetes. There is a strong connection between higher than avg blood sugar and high trigs. Obviously, that means lose the sugar, desserts, white flour/potatoes/rice/pasta, lower your fat intake, eat more green leafies and lean meat. Learn to like water or sweeteners(in limited quantities.) If you aren't used to working out it might be worth a few $$$ to hire a trainer to get you started and oversee your program for a month or so.
In my case,I DID develop type 2 diabetes and that scared me worse than the high triglycerides.Together it puts me at much higher risk for heart disease. I started counting carbs & cals and have so far lost 47-lbs. At this point my trigs are 147, pretty impressive change I think. My LDL(bad chol.) is now normal, HDL(good chol.) is still very low. Total chol is about 150; I haven't been below 200 in 10 years. I work out 3 times a week, still not as much as I should but I'm doing 3 times better than I was.
My blood sugars are in good control and I have more energy. Hope you will have the same results or better.
Congrats on getting your numbers down and your weight loss! Keep up the good work
