Hi there,
Sorry to hear about your grandson suffering.
It seems like he is suffering from acute
gastroenteritis which means just gut bug which has already started to slow down.
Most commonly it is caused by a virus which takes its due course and you just have to keep him hydrated till then. Often after such an infection, there is transient increase in gastro-
colic reflex which means whatever he eats or drinks will come out the other way.
In such circumstances, it needs patience, continue to keep him hydrated with
pedialyte and try to avoid the flavored ones since they can increase the
diarrhea load, try to encourage soft solid foods which are easy to digest.
Since he is already on alimentum, it is a safe formula to give during diarrhea.
If your grandson is having increasing diarrhea and unable to keep pedialyte down secondary to
vomiting, or decrease in urination, mucus or blood in his stools or fever, then he should be seen by his
pediatrician. And, in any of the above situations, I would suggest he should have his stool tested for WBCs, microscopy and culture.
Also, if he has been on prolonged antibiotics in the recent past and his diarrhea has started after being on these antibiotics, then he will need to be tested for an additional organism :
clostridium difficile toxin and be treated with antibiotics for the same if tested positive.
Hope this helps.
Regards,
Dr. Sumeet.
