But if they are present on parts of the body not exposed to trauma or without apparent cause, could be symptoms of some diseases, The expert: Armando Peña, director of haematology of the Clinical City of the Sea speaks more about the topic.

It is not pleasant to see nor touch the lesions known as bruising, or ecchymosis produced by the accumulation of blood under the skin, due to the traumatic rupture of the capillary surface.

Begin to be of violet color, and with the passing of days changes to brown, greenish and finally yellowish, up to disappear according to the changes suffered by the red blood cells out of capillaries damaged.

The specialist stated that when it is observed that a person has the tendency to get bruises for no apparent reason, you should perform a general exam to see if there is a disease. An example are the pathologies that produce failures in the mechanisms of clotting (for example, at the level of platelets) and in the blood vessels.

Among them we can mention, from the deficit of:

  • Vitamin K
  • Vasculitis
  • Hemorrhagic fevers
  • Among others.

It is also advisable to review the medicines you're consuming and ask for clotting studies and platelet counts, among others.
