Hey, I graduated from college about
2 years ago. When I was a student, I went to the Office of Students with Disabilities and explained my situation to them. They were extremely helpful and gave me a private room next to the bathroom. There was also a private bathroom down the hall from my room. They only required a note from my doctor to verify the information for their records. It's definitely a good idea to talk to somebody in charge of housing at the school. If they know what's going on, I'm sure they'll try to find suitable accommodations for your son so he can worry more about
his studies
