Very High or Low Levels of HDL Linked to Increased Risk of Infectious Diseases

By jeremyc | April 12, 2018

According to a new study, both high and low levels of good cholesterol might be bad for our health. These findings question the conventional belief that more of good cholesterol is better for us.

In this study, the researchers noted that when HDL cholesterol (commonly known as good cholesterol) is present in high or low amounts, the risk of developing an infectious disease is greater. Even more worrying is the finding that both high and low HDL cholesterol levels are linked to increased risk of death from infectious diseases.

HDL cholesterol is referred as the good cholesterol, because when it is present in high levels, it helps the body to get rid of excess cholesterol. Because of this reason, previous reports had suggested that high HDL levels are linked to reduced heart disease risk.

However, in the past few years, more than a few questions have been raised about the goodness of this good cholesterol. One study even noticed a link between high HDL levels and greater mortality risk.

In this study, the researchers noticed that people with extremely low HDL levels were 75 percent more likely to contact an infectious disease. They also noticed that individuals with extremely high HDL levels were 43 percent more likely to develop infectious disease. Further, both these groups were found to be more likely to die from infectious disease, compared to those with normal HDL levels.
