When you have symptoms such as coughing, wheezing, shortness of breath and chest tightness, you should see a respiratory clinic. When you see a doctor, you need to describe your medical history in detail including your condition and symptoms, such as whether these symptoms occur during the day, night or during exercise; whether they occur at home or at school or work; you also need to tell about your personal and family members’ health status; whether they are accompanied by lung diseases, rhinitis, seasonal allergies, food allergies, inability to breathe through the nose, etc.; whether your parents or siblings have asthma, eczema, rhinitis, allergies, etc. In addition, you should also tell your doctor whether you have pets, whether you smoke, your occupation and living and working environment. These are very helpful for the doctor to diagnose and treat asthma. Patients with asthma should take the initiative to tell the doctor that they have asthma when they see other diseases. This is because medication for many diseases can trigger asthma. Common ones include antipyretic and analgesic drugs (aspirin, paracetamol), antibacterial drugs such as penicillin, benadryl, betalactam, iodine-containing contrast agents, deworming drugs, etc.
