Watery motions 4-5 times a day with bloating, gas and urgency is acute gastroenteritis, most often viral or food related. The main job right now is fluid replacement, not stopping the motions - ORS after every loose stool, plus curd rice, khichdi, banana. Avoid milk, tea, oily and outside food for a few days. Do not take loperamide-type tablets if there is fever or blood in stool.
Next Steps
Take ORS and a zinc tablet for 10 days; most cases settle in 3-4 days. If there is fever, blood or mucus in stool, vomiting, giddiness or less urine, you need to be seen the same day. If it drags beyond a week, we test stool and rule out IBS or infection - consult me on Practo and I will set the treatment.
