Dizziness is only one symptom, and there are as many as one or two hundred diseases involved (the term varies and cannot be accurately counted). At the same time, many people (including patients and even some doctors) have developed misconceptions about dizziness, which is the main reason why I want to talk about it. The initial classification of dizziness is now relatively clear, but many dizzinesses have considerable difficulty in further confirming the diagnosis because of the different disciplines involved and the lack of specific tests. In recent years, I have been engaged in research on dizziness, and I can say that there has been a great progress in the diagnosis and treatment of dizziness, and the efficacy has improved compared to the past, but there are still many difficulties in diagnosis and treatment, and there is still a significant proportion of dizziness that is difficult to diagnose. Some patients with dizziness can be diagnosed, but there is no effective treatment yet; or they have some effect, but the efficacy is not very satisfactory, etc. Therefore, I am very concerned that many patients blindly believe that they have found a savior and come all the way to see me in the morning and early evening, only to be disappointed in the end. In addition, most dizziness cannot be solved in a single visit, and some even require hospitalization. Patients must take into account the longer stay in Beijing and the corresponding costs. Some dizziness can be solved locally and can be seen in a major local hospital, not necessarily in Beijing. It is important to consider carefully before coming to see me, and it is best to make an appointment to register in advance. Most dizziness is a chronic disease, so it is best to avoid the recent peak and come back after the heat has decreased a bit, when you can see more carefully.
