宁波袁昌亨先生: 人们外出旅行,或迁居外地生活,有些人总是感觉身体不舒服,发生厌食、呕吐、腹胀、腹痛,甚至腹泻不止等症状,这就是人们常说的“水土不服”。那么“水土不服”究竟是怎么一回事呢? 现代医学研究证明,所谓的“水土不服”就是患者染上了“菌群失调症”。原来,在正常情况下,人是处在一个庞大的微生物生存的环境之中,人的皮肤、黏膜和与外界相通的腔道,都有细菌、真菌等微生物的存在。 Mr. Yuan Changheng, Ningbo: People often travel abroad or move to live in the field. Some people always feel uncomfortable with anorexia, vomiting, bloating, abdominal pain and even diarrhea. This is what people often call “acclimatization.” So “acclimatization” what exactly is the case? Modern medical research has proved that the so-called “acclimatization” is the patient contracted the “flora disorders.” It turned out that under normal circumstances, people are in a huge living environment of microorganisms, human skin, mucous membranes and the channels connected with the outside world, there are bacteria, fungi and other microorganisms.
