Internal bleeding

Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside.^[1] It can be a serious medical emergency. How severe it really is depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities). Severe internal bleeding into the chest, abdomen, pelvis, or thighs can cause hemorrhagic shock or death if proper medical treatment is not received quickly.^[2] Internal bleeding is a medical emergency and should be treated immediately by medical professionals.^[2]
