Nowadays, many outpatients are often ignorant of their previous diagnosis, treatment and medication. When asked about the results of previous tests, many of them are lost, and when asked about the medications they take, they are confused. This is rather blind, which affects the doctor’s judgment and delays the timely diagnosis and treatment of the patient. The diagnosis of a Western doctor is, in the end, a process similar to “solving a case”. The accurate judgment of the disease is based on your previous clinical data, so bring all the previous medical information to the consultation, you can really avoid taking a lot of detours. It is important to know that even if the doctor gives you a detailed examination, your previous illness and the tests done at that time, such as head CT/MRI, are of great reference value. The doctor’s idea of judging a patient is: medical history (usually provided by the patient) + physical signs (the doctor helps you with detailed physical examination) + auxiliary examinations (the doctor’s preliminary judgment of your disease after targeted auxiliary examinations) + a comprehensive analysis of the above results. Therefore, in order for the doctor to have an accurate understanding of your disease, please make sure to organize your past medical information before you go to the doctor, prepare clearly and accurately express your disease process in advance, so as to maximize the clear diagnosis and achieve good treatment results.
