In most cases, ecchymosis occurs following a fall, blow, or hard bump. When this happens, blood vessels may burst and start leaking blood underneath the skin, resulting in a bruise. Some medications, such as blood thinners, dietary supplements, and antibiotics, are linked to burst blood capillaries and bruising. People who find bruises on their bodies on a regular basis but can’t seem to recall getting injured should see a doctor as soon as possible -- this can be a sign of an underlying medical condition. There are many medical conditions that may cause someone to bruise easily, including various bleeding disorders. For this reason, a person should visit the doctor if he or she sees large bruises on a regular basis, can’t pinpoint the reason for a bruise, has a family has a history of bruising easily, or begins to bruise more easily than before.
