“Who doesn’t know how to see a doctor”, you must be thinking when you see this title, right? But do you really know what you should do to prepare for a visit to the doctor? As the saying goes, “You don’t fight a war without preparation”. Everything should be prepared beforehand. Generally speaking, you should make the following preparations before your visit. 1, to eat a good breakfast before seeing a doctor, except for special laboratory tests, need to fasting blood draw, you should generally eat a good breakfast to go. Some people do not eat breakfast after waking up because of toothache, and then rush to the hospital by squeezing the public bus. Just sitting on the dental chair, see the dentist pick up the dental instruments, it produces nervousness, as a result, some patients appear head sweating, cold fingers, and even have the hypoglycemic symptoms of delirium. This is mainly a hunger, two tired, three scared caused by. 2, brush your teeth before seeing the dentist, do not go to the dentist after eating, with a mouth full of food residue. This has two disadvantages: ① when the dentist examines the teeth, first to spend time to remove the food residue accumulated on the teeth, in order to see the situation of the teeth; ② generally speaking, the dentist to see a relatively clean mouth, the heart is always more comfortable, but also convenient to do some tests and treatment. Especially to remind those who love to eat raw garlic, etc., there is a special smell of food, before seeing the dentist, must not eat this kind of food, this is the basic respect for the doctor, but also for their own smoother preparation for medical treatment. 3, dressed appropriately to see the dentist, we do not require as some important occasions, wearing expensive clothing, but also can not be too casual, wearing a sweatshirt undershirt. Rather, the general requirement is to dress appropriately, neat and generous. Although a breast scarf is worn during treatment, it is always unpleasant in the mind in case you accidentally dirty your expensive clothing when rinsing, rinsing, or spitting. It is worth noting that ladies should not wear heavy makeup, which will affect the doctor’s observation of your physical condition such as face color and lip color on the one hand, and certain examination operations on the other. 4, prepare a good medical history and medical information, the doctor will always ask your medical history and condition, combined with various tests, in order to make a correct diagnosis and give appropriate treatment. The medical history is how long you have had the disease; the condition is what symptoms you have, or uncomfortable situation. Now take toothache as an example, you should generally state the following questions: which part of the body hurts? Is the pain spontaneous or irritating? Is it a continuous pain or paroxysmal pain? Is it a mild vague pain or a severe pain? How long has the toothache been present? When describing the medical history, it is important to answer the questions concisely and accurately without exaggerating or narrowing it down, according to the doctor’s instructions. In addition, when you arrive at the hospital, how to register, are you clear?
