The cause of heavy bleeding in menstruation that follows missed periods is quite logical.

To get a doctor’s response to the question of what causes heavy flowing in a period after menstruation has been missed once or a few times, I consulted with Dr. Marlan Schwartz, MD, FACOG, robotic surgeon with Lifeline Medical Associates.

Dr. Schwartz explains, “The cycle consists of estrogen stimulating the lining of the uterus (endometrium) and ‘building up’ the lining.

“If this is not shed, and there are multiple reasons that could cause this, it will likely be kept being stimulated by more estrogen, thus causing the lining to be even thicker.

“If one then has a period or loss of this lining, as it has been made thicker (six or seven weeks of stimulation versus three weeks), there is more to shed.”
