Child Complaining Upset Stomach. Had Blood Discharge From Rectum Followed By Purple And Green Stool. Suggest?
Thanks for posting your query to XXXXXXX
Your 4 yrs old son is likely to be suffering from Acute Gastroentritis .The only alarming sign was the blood you mentioned in stools.When blood is seen in stools it indicates that it is dysentery.
Whether or not he needs a visit to the ER depends on the progress of symptoms - Keep a watch on the stools if there are multiple episodes of blood containing stools and the urine output becomes poor then get him examined by his doctor at the earliest. A few investigations could be done to identify infections and antibiotic depending on the results could be started.
In the mean time, you could administer an oral antiemetic medication which ever is available over the counter to stop his vomiting. Keep him well hydrated by giving him sips of Oral Rehydration solution after every stool. Keep his diet light; restrict any milk and milk products like cheese, butter, ice creams, etc. You could give him Yogurt which is a good probiotic.
Hope to have answered your query. Let me know if you need clarifications.
Regards
Take Care.
