Bruises in elderly people frequently occur because their skin has become thinner with age (senile purpura).Often, what are thought to be unexplained bruises on the shin or the thigh, for example, actually result from bumps into a bedpost or other object and failing to recall the injury.Unexplained, random bruises that occur easily or for no apparent reason may indicate a bleeding disorder or result from blood-thinning medications (anticoagulants), especially if the bruising is accompanied by frequent nosebleeds or bleeding gums.
