Frequently asked questions for your internist
Here we answer some of the questions that patients often ask an internal medicine specialist.
What is the difference between a family doctor and an internist?
A family doctor (often a specialist in general medicine) is the first point of contact for all health problems and coordinates further treatment. A Internist is a specialist doctor who specializes and deals in depth with diseases of the internal organs. Many internists also work as general practitioners, but often offer an extended diagnostic spectrum. Dr. Bruno works as a specialist and focuses on specialist internal medicine and cardiology care.
Do I need a referral for the internist?
Private patients can usually make an appointment directly, but should clarify this with their insurance company to be on the safe side.
Does an internist also treat psychological complaints?
A Internist primarily treats organic illnesses. However, there are close interactions between the body and the psyche (psychosomatics). Many physical symptoms can have a psychological cause or be exacerbated by stress. A good internist will recognize these connections and, if necessary, recommend further clarification or treatment by a psychologist or psychiatrist.
Does an internist also perform operations?
No, internal medicine is a conservative specialty. This means that a Internist does not operate himself. If the diagnosis shows that an operation is necessary, he will refer you to a qualified specialist in surgery or a specialist in the relevant field and coordinate the follow-up care.
What check-ups does an internist offer?
Internists play a central role in preventive healthcare. In our practice, we offer the statutory „Check-up 35“, which is carried out every three years from the age of 35 for the early detection of cardiovascular disease, diabetes and kidney disease. We are also happy to advise you on useful individual health services (IGeL) for extended preventive care.
My symptom affects several parts of my body. Is the internist the right doctor?
Yes, absolutely. Especially in the case of complex, systemic or unclear complaints, the Internist is the ideal contact person. Thanks to his broad training, he is trained to think beyond the boundaries of individual organs, combine symptoms and put the „puzzle“ together to form a conclusive diagnosis.
What does „general practitioner care by an internist“ mean?
When a Internist practicing as a family doctor, he acts as your primary contact for all health issues, just like a general practitioner. The advantage is that he can often carry out a more in-depth diagnostic clarification of internal medical issues directly in his own practice. At the Kardio Pro practice, the focus is on specialist care.
How does an internist treat high blood pressure?
Treating high blood pressure is a core task for everyone Internists. It begins with detailed advice on lifestyle changes such as diet, exercise and stress reduction. If this is not sufficient, drug therapy is initiated, which is individually tailored to the patient and any accompanying illnesses and monitored regularly.
Can I also come to the internist for vaccinations?
Yes, vaccinations are also part of the range of services offered by an internist. We are happy to check your vaccination status and carry out all standard and booster vaccinations recommended by the Standing Committee on Vaccination (STIKO) (e.g. tetanus, influenza). Good vaccination prophylaxis is an important part of preventive internal health care.
My family doctor doesn't know what to do, can an internist help?
