Dear Doctor, I am a teacher and I have a child in my class (8years old boy) who recently had a Kidney removed... What i would like to know is the following he is a very active child and i was told that because of his surgery that he will become more active , angry, nervous, and have sudden bouts of temper tantrums. Is this really due to the surgery ? I was also told that he should never be accounted for his miss behavior because this would increase these side effects...could you give me any information please
