'''Pseudodiarrhea''', formerly known as '''hyperdefecation''', is defined as increased stool frequency (more than three times daily) with a normal daily stool weight of less than 300 g (Fine and Schiller, 1999).
Pseudodiarrhea is often associated with rectal urgency and accompanies [[irritable bowel syndrome]], [[hyperthyroidism]], and anorectal disorders such as [[proctitis]]. Patients with rectal obstruction (e.g., from fecal impaction, obstruction due to a vaginal [[pessary]]) may also present with pseudodiarrhea, since only liquid stool can make it through (Chou and Yu, 2003; Tatar and Trivedi, 2005).
Pseudodiarrhea may be more common than chronic diarrhea and should always be considered in patients complaining of chronic diarrhea.
