Welcome to JustAnswer. A few questions will help me get a clearer picture of this situation:
10 hours ago
he can urinate but not defecate
urine yes, stool no.
no, but he acts nauseated
seems bloated but it is hard to the touch and he is shaking
Does he have any other medical conditions or take any other medications?
