我是位年近半百的中年妇女,不知何故,近两年来经常出现腹痛、腹泻等症状。到医院做过粪便化验、胃肠钡餐、肠镜等项检查,均未发现异常,吃了许多抗菌药物也无济于事。后来我仔细观察发现,还有个显著特点就是怄不得气,每当心情不好症状就加重。请问这是为什么?安徽徐丽媛 I am a middle-aged woman who is nearly half a year old. Somehow, abdominal pain and diarrhea often occur in the past two years. To the hospital for stool tests, gastrointestinal barium meal, colonoscopy and other items were found no abnormalities, eat a lot of antimicrobials also helpless. Later, I carefully observed that there is a notable feature is that no gas, whenever the symptoms of bad mood worsened. Why is this? Anhui Xu Liyuan
