Anyone here ever heard of (or experienced) Functional Diarrhoea! I have it myself. It has been recognised by the Rome IV Criteria as a FGD (Functional Gastrointestinal Disorder) like IBS. In fat it is considered to be a subtype of IBS-D (diarrhoea predominant irritable bowel syndrome) and has virtually all the symptoms of IBS-D except for he abdominal pain. I am not too clear on the mechanics of this form of FGD but that has been my latest diagnosis.
If anyone else here has that, or experienced similar symptoms, I would love to hear from you. The diarrhoea as in IBS-D can be urgent and yes, I have experienced more than my fair share of humiliating and embarrassing violent urgent public diarrhoea accidents (mostly from the inability to find a loo or cottage in time).
Thanks.
