There are currently no recommendations for setting a limit for HDL cholesterol as it is deemed as good, but there is mounting evidence that too much HDL can be equally as harmful as LDL cholesterol.
Research conducted by the University of Pittsburg found that in women going through menopause, an increase of HDL cholesterol actually contributed to greater plaque build-up, which increased the women’s risk of stroke and heart disease.
Other previous research found that high levels of HDL were associated with harm to the kidneys in dialysis patients, along with posing a risk to those with arthritis and diabetes.
“In certain circumstances, such as acute infection, or in chronic diseases linked to inflammation, such as rheumatoid arthritis, research has suggested that the HDL particles change their make-up,” added Professor Naveed Sattar from the University of Glasgow. He explained that the rising levels of HDL cholesterol in the body increase the chances of malfunction and resulting complications.
