Thank you for your query at AskTheDoctor.com
I understand your concern.
Watery yellow diarrhoea is a sign of acute gastroenteritis, mostly a bacterial infection. I will advise you to consult your family physician who can prescribe you a course of Tab. Ciplox 500 mg twice daily for a week. Also, Loperamide can be taken SOS for relief from frequent BM.
Hope this was helpful,
