About High-Density Lipoprotein
HDL is considered 'good' cholesterol, helping to remove excess cholesterol from the bloodstream.
The reasons for low HDL
A low HDL level can be caused by poor diet, lack of physical activity, smoking, obesity, insulin resistance, or genetic factors. Consuming trans fats and refined carbohydrates, as well as living a sedentary lifestyle, reduces HDL levels. Chronic diseases such as type 2 diabetes and metabolic syndrome also contribute to lower HDL.
The reasons for elevated HDL
Extremely high HDL levels can sometimes be linked to genetic mutations or excessive alcohol consumption. However, having excessively high HDL may not always be protective and in rare cases, can be linked to increased cardiovascular risk.
Is it bad too have too high/low HDL?
Low HDL levels are associated with an increased risk of heart disease, as the body is less able to remove excess cholesterol. This can lead to plaque buildup in arteries, increasing the risk of heart attacks and strokes.
Moderately high HDL levels are generally beneficial, but excessive levels could indicate a dysfunctional cholesterol transport system, potentially increasing cardiovascular risks in rare cases.
