Cholesterol is made by the liver and carried in the blood all around your body. It’s taken out of blood and into the cells to be used or stored, and any excess cholesterol can be carried back to the liver and broken down. When a person has too much cholesterol, however, this process does not run as smoothly, and dangerous health complications can ensue. If you notice yellow bumps on your knuckles when you clench them it could be an indication of high cholesterol.
Having hard, yellow bumps over your knuckles could be a sign of a potentially fatal cholesterol condition known as familial hypercholesterolaemia.
Cholesterol deposit lumps will protrude when a sufferer clenches their fist, known as then xanthoma.
If left untreated, people with familial hypercholesterolaemia could possibly die from a heart attack at a young age because they have extremely high cholesterol levels.
About one in 200 people in the UK are affected with the condition, so it’s important for one to get their cholesterol checked, particularly if you have a family history of heart attacks.
The ‘hyper’ part of hypercholesterolaemia means ‘too high’, explains Heart UK.
“The ‘cholesterol’ part simply means cholesterol, a type of fat, and ‘aemia’ means ‘in the blood’.
“So, hypercholesterolaemia means too much cholesterol in the blood. And this can clog up your blood vessels.
“The ‘familial’ part of familial hypercholesterolaemia simply means it runs in families.
“FH is passed from parent to child in the genes, and it’s usually possible to trace FH back through several generations.
“With FH, there is a fault in one of the genes involved in removing cholesterol from the blood.”
