The visible warning sign on your knuckles of high cholesterol levels
HIGH cholesterol is pernicious because the heart disease marker does not usually present symptoms. However, very high LDL levels can be signalled by changes on the knuckles in certain people predisposed to high cholesterol.
Cholesterol is a waxy substance that your liver produces naturally. As the British Heart Foundation (BHF) explains, it is needed to stay healthy because every cell in our body uses it. However, having “high cholesterol” means you have a lot of LDL cholesterol in your blood. LDL cholesterol collects on the inside of your arteries, thereby raising your risk of heart disease and stroke.
