Developed diarrhea and irregular bowel routine after eating Chinese food.
Acute gastroenteritis/dyspepsia very likely.
Thank you choosing 'Ask a doctor' service for your query,
The symptoms you are describing are mostly suggestive of Bacterial gastroenteritis (commonly called stomach flu).Having symptoms after having Chinese food is again suggestive of the same.It involved bacterial infection of the intestine causing inflammation.Inflammed intestine fails to digest food and absorb water properly causing loose watery stools.
Stool analysis and culture are required to confirm the diagnosis.
Management is with antibiotics (usually a combination of Ciprofloxacin and Metronidazole) for which you will need a prescription. So please be advised to follow up with the urgent care.
Meanwhile, drink plenty of electrolyte containing drinks like Gatorade and oral rehydration solution.
Follow soft diet.
BRAT (Banana, Rice, Applesauce, and Toast) diet will be easier on your tummy and would be easy to digest.
Keep taking probiotic.
To stop loose stools take over the counter Imodium tablet 4 mg twice daily.
Stop taking laxatives for few days.
Feel free to follow up.
