Bruises on Your Body May Be Warning You About an Underlying Health Problem

Frequent or unexplained bruises may be an early sign of certain medical conditions.

Most people have experienced bruises after bumping into furniture or suffering a minor injury. In many cases, these marks fade within a week or two and require no treatment. However, if bruises appear frequently, develop without any obvious cause, or occur in unusual places, they may be a warning sign of an underlying health condition that should not be ignored.

What Causes a Bruise?

A bruise, also known as a skin contusion or hematoma, occurs when small blood vessels beneath the skin are damaged. Blood leaks into the surrounding tissue, causing the skin to change color from red or purple to yellow before the bruise gradually disappears.

Bruises caused by minor injuries are common and usually heal on their own without leaving scars.

However, bruises that appear repeatedly, persist for a long time, occur without injury, or are accompanied by symptoms such as fatigue, fever, weight loss, poor appetite, muscle or joint pain, swollen lymph nodes, or general weakness may require medical evaluation to identify the underlying cause.
