Bleeding is a problem that all of us can face from time to time. The most common reason is some form of injury, although such injuries are usually relatively small.
During bleeding, blood normally leaks out of the body, at least until it is clotted and the flow is stopped; however, not all bleeding occurs outside the body. Injuries to internal blood vessels can cause blood to leak out from the vessels and collect in the area. While they are often not a problem, they do have the potential to be dangerous in some cases.
Here’s a look at some of the most common causes of hematomas.
Cause #1: Minor Physical Trauma
The occasional bump or knock is more or less inevitable. We can carelessly bump into a table or another part of the furniture around the home, or maybe even get involved in a physical altercation with another person. The impacts caused can cause the blood vessels beneath the skin to become ruptured, leading to a hematoma.
This type of hematoma is what we commonly call a bruise. They can sometimes be caused by the slightest of knocks, maybe leading to bruises that are barely noticeable. They will usually go away by themselves in time and should cause no lasting damage.
