Suggest Treatment For Acute Diarrhea

today i had acute diarrhea...i had no idea that anything was going to happen until i felt water (which i thought it was..urine) then the smell came and it was liquid poo. it filled my panties,pants,soxs, and shoes, in a very short time. i shuffelled to the bathroom and got on the toilet and for 20 minutes i filled the toilet with liquid poo...what is going on/ this has never happened before. joanne from minnesota
