The student welfare organisation, Sit, can help you book an appointment with the campus nurse sit.no/en/health/campus-nurse, a psychologist sit.no/en/health/psychologist, or dentist sit.no/en/health/dentist. These services are all provided at student rates and you do not need a referral from a doctor.
If you are staying more than 6 months you are entitled to a personal physician. You should register for a physician as soon as you have your national ID number. Do not wait until you get sick. If you are studying for less than 6 months in Trondheim, you will not get a personal physician. However, you are still entitled to medical care.
