Thanks for posting your query.
With the available described symptoms, there could be possibility of irritable bowel syndrome
predominant diarrhea type or viral gastroenteritis
Presence of frequent loose motions with excessive flatulence suggest the diagnosis.
You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should also go for complete blood count
, thyroid profile, blood sugar and serum calcium.
You should also go for colonoscopy
and UGI endoscopy with biopsy of duodenum.
You should maintain your hydration with potassium rich solution.
You should avoid milk and all milk related products.
Treatment depends on the diagnosed disease.
