Hello,
The most common cause of diarrhea is
gastroenteritis, food poisoning,
indigestion, infection(salmonella, shigella),
food allergy or
lactose intolerance.
Take anti-diarrheal(Loperamide, Imodium or
Pepto-Bismol) medicine. Get stool examined(R/E & C/S), if the infection is caused by bacteria, you may need antibiotics.
Keep yourself well hydrated, take ORS, soups, juice & plain water. Take banana(raw-boiled or ripe), oatmeal & semi-solid food in small amounts.
Avoid dairy products & stay away from addictions & greasy food. Take boiled homemade food.
If diarrhea is still persistent visit ER, you may need medical support with intravenous fluids & antibiotics.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
