| Re: Low HDL (33), but low LDL (53), TC (101), and Trig (74)
The usual criteria indicate lower risk due to low TC / HDL ratio, but higher risk due to HDL < 40. Your doctor is as puzzled by the results as well?
You may want to consider getting a more detailed blood lipids test, particularly if you have family history of heart disease in people who do not have the usual risk factors (high LDL cholesterol, smoking, high blood pressure, diabetes, etc.). The more detailed tests include things like:
* Direct measurement of LDL (instead of approximating LDL = TC - HDL - TG / 5)
* Type of LDL (small dense is more dangerous than large buoyant)
* Type of HDL (large buoyant is more protective than small dense)
* Lp(a) or Lipoprotein A (high levels are high risk even when LDL, HDL are good)
You may want to increase exercise, since that raises HDL (and reduces the risk of diabetes). Obviously, if you smoke, stop smoking, and if you have excess body fat, try to lose it, since high body fat makes it more likely to have bad LDL numbers, high blood pressure, and diabetes.
