JAKARTA - Bruises on the body are quite common. Bruises can appear after someone hits a hard or soft object, which damages small blood vessels under the skin.

When these small blood vessels rupture, blood seeps into the tissues under the skin. This causes a bluish or purplish color known as a bruise.

In most cases, bruising is not a dangerous condition and can heal on its own. However, in certain conditions, bruising can appear without any obvious cause and can be a sign of a more serious health problem.

CEO of the Leukaemia Care organization, Nicole Scully, said bruises that appear for no apparent reason can be a sign of a serious health problem.

"When you don't hit anything or don't get hit, but still have bruises on your body for no reason, it could be something to watch out for," Scully said, quoted by The Guardian, Saturday, March 7, 2026.

In addition to its appearance without cause, other symptoms that occur along with bruising must also be watched out for. Such as unusual bleeding, to excessive fatigue.

"He also advised to be aware of other symptoms such as unusual bleeding, repeated infections, excessive fatigue, and pain that appears without explanation," he said.

The location of the bruise should also be considered. If it appears in areas that are often hit, such as the knees, shins, or elbows, it is usually not too worrying.

However, if bruises appear on softer parts of the body such as the stomach, back, then it can be a sign of health problems. Bruising in these areas can indicate a problem with the blood vessels or the blood clotting system.

Changes in the size and color of bruises can also be a sign to be aware of. Normally, bruises are red when they first appear, then turn bluish or blackish in a few days, and as the healing process turns green, yellow, or brown before finally disappearing.

However, if the bruise is very large in size or very dark in color, it can indicate a serious disease such as leukemia.

"The bruises that appear as symptoms of leukemia can vary in size, ranging from small to the size of a dinner plate and dark purple in color," he explained.

Thus, if bruises appear more often than usual, have no obvious cause and are accompanied by other symptoms, then it is best to immediately see a doctor to get the right diagnosis and treatment.
