If you have severe and frequent unexplained bruising, it's a good idea to see a physician to rule out such disorders, especially if it seemed to come on suddenly.
Bruising is caused by internal bleeding (under the skin) and occurs when a person has injured themselves. Some people are naturally more likely to bruise than others â for example, elderly people may bruise more easily because their skin is thinner and the tissue underneath is more fragile. If you suddenly get lots of bruises, or start to bruise for no obvious reason, tell your GP.
