What are the cause of internal bleeding?

Answer:
i believe this happens because of high blood pressure...when vessels start bursting due to high pressure.internal bleeding mainly occur during heart attacks.

Internal bleeding can ba caused by a number of things. Trauma is the most common. Car accidents, fall, etc most commonly cause internal hemorrhaging. Heart attacks have nothing to do with internal bleeding. They are caused by a blockage in an vein or artery.

Bleeding can also be caused by ingesting too much aspirin.
