Thanks for writing your query.
Yes, you should be concerned about the symptoms.
You should get her stool examined for Routine/Microscopic and Occult blood.
She seems to be having infection of the intestine and needs antibiotic and antiamoebic for full recovery along with antacid
. Medicines can be planned according to the report of the investigations.
She should be given light meals with less spice and oil for few days until her stool gets normal again.
Also take care of her hydration. She should be adequately hydrated and her urine output should be normal.
It is advisable that you should get her examined by her Paeditrician.
I hope this is helpful to you.
