Try to tell the hospital beforehand if you need an interpreter present when you're admitted to hospital - an interpreter can help you ask questions and help you fill in a consent form. Some hospitals can also arrange different types of ethnic food if they know you're coming. You can also ask if it's possible for relatives to bring food in for you. If you'd like to see a minister of your religion during your stay, try to tell the hospital beforehand. Tell the nurse on duty - you have a right to have these needs respected.
Some hospitals have a special room where patients or relatives can pray.
The nurse can tell you where this is. In most hospitals, yes. Just check with the hospital before you go. If you don't wish your condition to be discussed, your wishes will be respected. The only exception is where patients are incapable of making decisions for themselves.
