Child Has Norovirus. Started Vomiting And Noticed Black Stringy Thing In Stool. Concerned
Thanks for the query.
I understand your concern.
Presence of black stringy things in the stool may be due to undigested fiber from the banana.
But as you have mentioned foul odor in stool & diarrhea, it can be attributed to Gastroenteritis (viral, bacterial or parasitic etiology).
If I were to be her treating doctor, I would recommend use of albendazole suspension to take care of parasitic infection. Alternatively you could choose to wait for 2-3 days, if it is due to undigested fiber from the bananas, it will go off on its own. If it persist you can get a stool test done.
In the meanwhile, maintain adequate hydration in the form of fluids & ORS, and give her soft, non spicy diet.
Wishing your daughter a Good Health.
Let me know if I need to clarify further.
Take care
