Anemia is a common blood disorder. Some of the symptoms of this condition are headaches and nosebleeds. However, when the headache is accompanied by a nosebleed, it can result in iron deficiency which can contribute to further blood loss.
A deviated septum is the displacement of the septum (the cartilage that separates the nostrils inside the nose), which makes one nasal air passage smaller than the other. This respiratory condition can lead to facial pain and difficulty breathing, which may damage the thin vessels in the nose.
Head injuries are common in sports. Such unfortunate events can lead to head injuries and concussions. A sudden strike or bump in the head of a player, for instance, may result in a headache accompanied by a nosebleed. This can also lead to more serious complications.
Some studies suggest that nosebleeds are possibly related to migraines or throbbing headaches. According to research, a headache or migraine accompanied by nosebleed occurs because of a sudden increase in blood pressure, as well as the nasal congestion that widens the thin blood vessels in the nose.
Dry and humid weather can contribute to headaches and nosebleeds. The dryness of the atmosphere at certain times, the sudden drop and increase of temperature, and seasonal changes can cause the tissues of the vessels in the nose to dry up and form cracks.
Similar to allergies, viral infections can also lead to a headache accompanied by nosebleed. The common cold tends to block the nasal airway. It can also damage the blood vessels.
