It is hard to say how long your visit to the outpatient department will take. A medical specialist will ask you for details on your health issues. If necessary, he will discuss with you what additional tests and treatments you may need. The specialist will inform you about the (possible) cause for your symptoms and how they can be treated.
Prepare yourself well for a consultation with your medical specialist en write down any questions you might have. Tell your specialist everything he needs to know about your health situation. If anything is unclear or if you are unsure about something, please tell your specialist.
