Menstruation occurs when an ovum failed to get fertilised. This shedding of the womb's inner lining is related to the release of a special class of hormones known as prostaglandins. Prostaglandins cause the smooth muscles of the womb to contract which help to shear off its inner lining. This contraction is also the reason for the painful menstrual cramps that most of us are familiar with.
When there is an excessive release of these hormones during menstruation, the smooth muscle in the intestines may respond in a similar manner resulting in more frequent stools or diarrhoea. For some individuals, the stress encountered during menstruation can aggravate their underlying IBS resulting in looses stools.
The treatment for this condition depends on its severity and the frequency of the loose stools. Simple anti-cramps medicine and medicine commonly use for diarrhoea may work perfectly. In severe cases, non-steroidal anti-inflammatory drugs may be required to treat both the menstrual cramps and loose stools.
Do note that hormonal cause of looses stools should not come with blood in the stools. Such finding should prompt you to seek medical help soonest possible.
