The same remarks made respecting the preceding condition apply to this. There is no definite standard as to the length or quantity of the menstrual flow. When the flow is much more than usual, or so excessive as to produce weakness and prostration either at the time, or after, it may be termed menorrhagia.

Menorrhagia may be produced by either plethora or debility. When resulting from plethora, the patient suffers with severe throbbing headache, pain in the back, and general symptoms of fever. When it results from the opposite condition, the patient is very weak, pale, and thin in flesh, and the flow is almost continuous, one period begin ning almost immediately at the conclusion of the other. In addition to plethora and debility, menorrhagia may be the result of chronic congestion of the uterus, prolapsus and other displacements, tumors, laceration of the neck of the uterus, disease of the heart, liver, lungs, and other important organs.
