贺女士今年37岁,最近3个月来,一到晚上躺下睡着一、两小时后,就开始厉害地咳嗽。奇怪的是白天几乎不咳,而且有时是睡着3小时后才咳,有时天快亮才咳。一旦咳嗽就会咳到无法呼吸的地步,另外常伴有胸闷及快窒息的感觉,即使坐起来还是咳。有时一咳就好几小时都不会好,但咳嗽始终没有痰,还会出现哮呜声。去医院检查,医生听到哮呜声,诊断为气喘,用了气喘药后,不但没改善,反而夜咳次数更频繁。贺女士的丈夫见情况严重,就陪她到大医院就诊。医生检查咽喉时,发现整个咽喉呈现鹅卵石状的肿胀,严重时有些会红肿,这是很典型胃食道逆流所造成的组织伤害。那么,胃酸逆流是怎么回事呢? He is 37 years old this year, the last 3 months, one night lying down and fell asleep one or two hours later, began to cough. Strange is that the cough is scarce during the day, and sometimes it is asleep after 3 hours of cough, and sometimes it is bright. Once coughs will cough to the point where it can not breathe, the other often accompanied by chest tightness and fast asphyxia feeling, even if you sit up or cough. Sometimes a cough for several hours will not be good, but the cough has no sputum, but also there will be whistling sound. Go to the hospital for examination, the doctor heard the whistling sound, diagnosis of asthma, asthma medication, not only did not improve, but the frequency of night cough more often. Ms. He’s husband saw the situation is serious, to accompany her to a large hospital. When the doctor checked the throat, he found the whole throat showed pebble-like swelling, some severe swelling, which is typical of the gastroesophageal reflux caused by tissue damage. So, the stomach acid reflux is how is it?
