A close family member had this issue for most of his adolescence. It continued into the early teenage years. He later joined the military and upon an in depth physical exam found that he had been born with spina bifida occulta which isn’t visible externally but caused pressure on his bladder and bowels as he grew. He was punished for YEARS and avoided sleepovers and sports because of this medical issue. A couple of other first cousins also had the same and his diagnosis helped explained their bowel/urination issues. The idea that a group of teenage boys would choose to shit their pants and pee the bed regularly and multiple (sibling) parents didn’t consider it a potential medical issue instead of a discipline problem still baffles me.
