welcome to healthcare magic,
if your daughter is having persistent diarrhoea
it would be good to do a stool test
to rule out any kind of infection, to do h-pylori
test to rule out ulcers,
side effect of drugs can cause diarrhoea and bloating.
if she has bleeding accompanied with diarrhoea then would rush for a colonoscopy
from the brief history you have given me, she might be suffering from ulcers, she has many risk factors pointing to that these include.
- food allergies.
would suggest she needs to be investigated to know what is causing the problem would benefit from endoscopy
yes she will benefit from a dietician for the food she needs to eat.
hope to have answered your query
wish your daughter a quick recovery and dont be stressed life is short enjoy it to the most.
