Can HDL cholesterol ever be too high?

No. There are no known side effects of a high hdl. Remember HDL - healthy cholesterol.
Hard to tell. High HDL the "good cholesterol" so more should be better.... This is true for groups of patients. For individuals, it is less clear. High HDL levels can occur when we absorb more cholesterol in the gut, and have more building blocks of HDL (apoa1). Very high HDL can sometimes not work as well. High HDL should not prevent treating other risk factors such as high ldl, high blood pressure, etc.
Not that we know. Currently HDL recommendations highlight a minimum number that we like patients to achieve. This numbers by age and sex. There is currently no maximum HDL number, that above which there are associated detrimental effects. Therefore, the current thinking is that the higher the HDL number the better. This number is subject to significant genetic predisposition but can be lowered by diet, smoking, etc.

Hdl cholesterol level is high. Can it ever be too high?

No. Hdl (high-density lipoprotein) isn't really a cholesterol measurement to begin with....It's a carrier protein that assists in transporting away and decreasing risk of cholesterol deposits in blood vessel walls. There are no studies indicating a "dangerously" high level, but, of course, a high HDL is a great heart protective measurement. Read more...
Unusual over 100. Hdl cholesterol (hdl-c) levels over 100 are vary uncommon. In general, high hdl-c may be the result of genetics (hyperalphalipoproteinemia), exercise, increased alcohol intake, or medications (niacin, fibrates). Rare causes include obstruction in the biliary tract, very high blood levels of dilantin, and organophosphate toxicity. Read more...

What does it mean to have high HDL cholesterol?

Good. Hdl is the good cholesterol and having a high level of it will stand against the effects of the bad cholesterol called ldl, so having a high HDL can help in eleminating risk factors for having a stroke or a heart attack in the near future. Read more...
It's good - usually. High hdl-c (> 60 mg/dl) is usually a very good sign. But, risk is always moderated by ldl-c, triglycerides, blood pressure, lp(a) level, family history, smoking, diabetes, exercise, weight/obesity, etc. So, all things equal, good is usually better, but don't forget it's not a safety net. Finally for those with a very high HDL (> 75) your doctor may want to check the size of the particles once. Read more...

Can you have too high HDL cholesterol levels and get some illness?

No. Hdl (high-density lipoprotein) is actually not a cholesterol product at all, but a protein that carries cholesterol away from blood vessels. There are no studies indicating too high of a level. Read more...
High HDL Cholesterol. There is some data linking very high HDL cholesterol to increased cardiovascular risk. Some feel that it is not the level of HDL that matters but rather it's "functionality" or how well it is working that makes the difference. One could have very high levels of non-functioning HDL , or low levels of highly functioning hdl. Right now we have no commercially available tests to determine this however. Read more...

What does high HDL cholesterol mean? Is that the good kind or the bad kind?

The good kind. LDL and triglycerides contribute to arterial plaque formation while HDL breaks down arterial plaques. HDL is the healthy cholesterol, so a high HDL is a great thing. Read more...

What should I eat if HDL cholesterol is slightly low and albumin level is slightly high?

Eat fish & exercise. Hdl is not predominantly influenced by diet. Hdl is primarily regulated by genetics but can be increased by exercise, omega 3 fatty acids , weight loss and to a small extent wine .The best way to raise your HDL level is by increasing your aerobic exercise to at least 3-5 times a week for at least 20 minutes. Eat fish high in omega 3 fatty acids, epa and dha or take omega 3 capsules. Read more...

Is an extremely high HDL cholesterol level unhealthy?

Probably not. Hdl contains "good cholesterol", the proteins primarily associated with transport of cholesterol away from the arteries. If it is very much higher than normal, i would consider advanced lipid testing to further understand your lipids. Read more...

My most recent HDL cholesterol level was so so. How high can HDL go?

I've seen 125. The highest hdl-c i've seen is 125 mg/dl. I've seen many just over 100. Optimal is over 40 for men and over 50 for women. Over 60 is considered very good. Read more...
Hard to tell. As a lipidologist i often get referred interesting cases, most recently someone with an HDL cholesterol level of 168. This patient was a high absorber of cholesterol in the intestine, with very high levels of a protein called apo a1, the building block of HDL cholesterol . While her total cholesterol was high, and hdl, everything else was normal. These can be confusing cases. See a doctor. Read more...

Don't Know. High hdl-c ( HDL cholesterol ) levels are associated with lower risk of heart disease for populations of patients. For individuals, however we cannot say this. In fact, high HDL can be cause by many things, one of which is increased cholesterol absorption, and may not protect against elevated levels of LDL cholesterol or apo b or LDL particle levels . Hdl can be high but "dysfunctional". Read more...
