At the evaluation of these findings we have to consider the indication
of senna treatment, i.e. constipation of pregnant women.
Two groups of constipations can be differentiated. If the onset
of constipation occurred before conception and continued during
pregnancy, these conditions were considered as chronic. However,
therewas a newwave of “pregnancy constipation” mainly after the
third gestational month and it may associated with the common
oral iron therapy during pregnancy which may exacerbate constipation,
poor oral fluid intake due to nausea and vomiting during
pregnancy, increased transit time due to slower gastrointestinal
movement (explained by higher production of progesterone) and
alteration in diet.
