Taking the medical history (anamnesis):
In the very beginning of the diagnostic process the doctor tries to get an overview over the present complaints, their chronology, related diseases and previous therapies by a comprehensive dialogue with the patient or - in some cases - with relatives. Medical history of the family, the actual and former professions / employments, the social conditions and of allergies are taken into account as far as relevant.
You can facilitate the doctors job by making notes about previous diseases and operations already at home before you have your appointment. A list of your previous and actual drugs including the dosage is also very helpful.
Anamnese If there are actual or former X-rays or CT-scans of the chest or – at least – the written reports you should have them with you if ever possible. Former medical reports are also important.
By assessing the medical history vital information can be won. Only after that the next diagnostic steps can be arranged.
