Internal Medicine — what to know

An internal medicine doctor (internist) deals with diseases of the internal organs in adults — the heart, lungs, stomach, liver and kidneys. People see one for complaints when it is unclear which specialist to see, for several long-term conditions at once, and for a check-up.

What happens at the visit

The internist asks in detail about your complaints and earlier illnesses, measures your blood pressure, listens to your heart and lungs and examines your abdomen. When needed, they order blood tests, an electrocardiogram or an ultrasound and refer you to a narrower specialist.

Before the visit

Bring an identity document, the results of earlier tests and any discharge summaries, and a list of the medicines you take.

Bring the discharge summaries and results from the past year. If you take many medicines, bring their boxes or a full list with the doses.

Visits paid by НЗОК (NHIF)

A specialist visit paid by НЗОК (NHIF) usually needs a referral from your GP; a referral is valid for 30 days. A paid visit is possible without one. Whether the doctor sees НЗОК patients, which health funds they work with and the price are on their profile.
