大多数疾病并非一夜之间就会出现。它们常常经过数年时间,通过一些最典型的预警信号宣告它们的存在。△胸区痛经常性的胸区痛是冠心病的前兆,但是人们往往对此不在意,以至造成严重病变。因此,人们应对此引起重视,及时到医院进行检查。△耳鸣某人耳朵里有嗡嗡声或叮叮咚咚声,这经常是他可能患了中耳炎的最初迹象。如果某人耳内有叩击声,这预示他患有高血压病。糖尿病、食物过敏反应和循环障碍也能引起耳鸣。△眩晕某人如果耳朵突然失聪或者四肢有如蚁走感,这多数是他得中风病的先兆。如果某人突然头晕,并伴有头痛、恶心、呕吐或者意识障碍,那么,他也许患了脑溢血病。 Most diseases do not occur overnight. They often declare their existence over some of the most typical warning signals over the years. △ thoracic pain recurrent thoracic pain is a precursor of coronary heart disease, but people often do not care about this, as well as causing serious disease. Therefore, people should pay attention to this and promptly go to the hospital for examination. △ tinnitus Someone in his ears buzzing or ding dong sound, which is often the first sign of his possible otitis media. If someone has a tapping noise in the ear, this indicates that he has hypertension. Diabetes, food allergies and circulatory disturbances can also cause tinnitus. △ vertigo If someone suddenly deaf ears or limbs like ants feel away, this is mostly a sign of his stroke. If someone is suddenly dizzy with headache, nausea, vomiting or disturbance of consciousness, he may have cerebral hemorrhage.
