What causes large-caliber stools in a teenager?
Large caliber of stool
Hello and Welcome
I appreciate your concern
Quantity and caliber of stool can vary from person to person. I would have been more concerned if the caliber of the stool was small , which might have warranted further testing. If the stool are soft, there is no pain on defecation then there is nothing to worry about. To be on the safe side , stool for ova and parasite can be done if he complains of any perineal symptoms such as burning or pain and itching pre or post defecation.

The bmi calculated is 19.8 which is normal for a 15 year old. He has time to grow. No need to worry too much about it in my view.
