Agreed. Not eating when you're already constipated just makes it worse. You need to especially eat plenty of fibre and drink plenty of fluids to prevent it getting worse.

I'm not sure the hospital is needed at the moment... You need to see a Dr about treating the constipation if OTC stuff hasn't helped, and a pdoc about changing the AP to something less constipating. They will also be able to advise you better than random strangers on the internet about whether hospital is needed or not.

All the best,
