Hello, The given symptoms of yellow color diarrhea could be due to infection and it could be bacterial infection, low bacterial load may not need any treatment, it may come around on its own. If the bacterial load is high, then it may needs antibiotic, if the diarrhea is not there, then it is nothing to worry, it will comes around soon. You could wait for couple of days, if the symptoms remains as it is, then condition can be managed with tablet Ciprofloxacin with Tinidazole twice in day, for three days. But looking to given history and symptoms, it will be fine soon even without the medicine, just you will have to take care in diet, avoid taking spicy food, fried food, have semi solid diet with lot of drinking water. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Akhtarhusain
