So-called good cholesterol helps get rid of the bad




 

 

DEAR DR. DONOHUE: I have a yearly checkup with a number of blood tests. All has been well for a number of years, except for my HDL cholesterol. I am a 62-year-old woman, and my HDL has hovered around 39. I watch my diet carefully, exercise daily and have taken and am still taking niacin, but the HDL refuses to budge. My total cholesterol and LDL cholesterol are fine. What should I do? — L.Y.

ANSWER: HDL cholesterol is the so-called good cholesterol. It’s believed to remove cholesterol from the walls of arteries and take it to the liver for disposal. For women, HDL cholesterol ought to be 50 mg/dL (1.3 mmol/L) or higher. For men, the target is 40 (1.04) or higher.

British researchers have punctured the HDL balloon. They say that HDL cholesterol doesn’t protect the heart and that its benefits have been greatly overblown.

HDL is a complicated substance, composed of a variety of components, each having different and often opposing effects. The full extent of how it figures into artery-hardening and heart disease hasn’t been completely explained.

If you were my patient, I’d tell you to forget your HDL cholesterol. You’ve done everything you can to raise it, but it hasn’t budged. More importantly, your total cholesterol and bad cholesterol, LDL cholesterol, are at favorable levels. The main attention should be directed to these cholesterol components. If your doctor hasn’t said you need to be strict about HDL cholesterol, don’t pay so much attention to it.

The booklet on cholesterol details its effect on the body and the heart. It does not contain this information on HDL cholesterol, however.
