My daughter who is 11, woke up with an uncontrolled loose yellowish bowel movement.  Throughout the day she has had stomach cramps and foul smelling loose yellow mucousy stools.  No fever, no vomiting.  So think this may be serious or just a stomach bug?
Please examine his stool so that can be given medicines as per the reports of stool examination, if it shows pus cells will need to put him local antibiotics pl check the stool then I will guide you ok
