Headache can be caused by head diseases, anemia, constipation, gas poisoning, alcoholism and mental fatigue. Headache may be caused by the stimulation of meninges and the contraction of blood vessels, which leads to an increase in tension, or it may be that the brain sends a signal that we are short of oxygen and need more oxygen.
