Bleeding usually starts from one nostril. In case of heavy bleeding, it may fill up both the nostrils and overflow the nasopharynx. In certain cases, blood may drip back from the nose through the throat to stomach. A person is likely to vomit in such a condition. The common signs of excessive nosebleed are:
- Excess blood loss may cause dizziness and fainting, confusion, loss of alertness and light-headedness. However, the condition is rare.
- Bleeding from other body parts like teeth, gums, nostrils, etc. indicate inability of blood to clot.
- Additional bleeding from other parts of the body, such as bleeding gums when brushing teeth, blood in urine or bowel movements, or easy bruising also indicate an inability of the blood to clot.
