Fasting: We often encounter patients who come to the hospital early in the morning from more than a hundred miles away to see a gastroenterologist, register and queue up, and when it is their turn to see the doctor, the doctor asks about their medical history only to find that they have eaten, so they have to reluctantly tell him that they cannot do the relevant tests after eating and need to return to come back the next day on an empty stomach. In fact, not only to see the stomach, many items of internal medicine are required to fasting examination, so if you can not figure out whether you need to fast before the visit, it is best not to eat, water. Bring all the examination materials: some patients have done a number of tests in the local hospital, because the diagnosis is unclear before going to higher hospitals, they often think that since they go to a large hospital to see a doctor, bring the local examination materials is useless, in fact, these tests often have very important reference significance, especially some acute, serious patients, the local examination can often help doctors in large hospitals to quickly rule out the possibility of some diseases, to reduce the duplication of The local tests can often help doctors in large hospitals to quickly rule out the possibility of some diseases, provide a reference for reducing duplication of tests and conducting more targeted tests, and win valuable time for the treatment of diseases. Keep a list of used medications: Ask your local doctor to make a list of used medications so that you can avoid repeated medications on the same day, reduce the possibility of drug poisoning and adverse reactions, and also help the doctor to judge the efficacy of the medications used to facilitate the re-selection of medications. The first visit to the medical record book: the medical record book is used to make a record of the patient’s condition, detailed medical records are very important for future follow-up, patients may not always be able to find the same doctor each visit, medical records can allow future doctors to quickly and comprehensively grasp the past condition.
