Farting with thin stools may be a physiological condition, or it may be caused by acute enteritis, anal sphincter relaxation and other factors. 1. Physiological situation: when farting, the instantaneous pressure in the intestines is higher, along with the rapid passage of gas through the intestines. If the gas appears at a higher site, the water is too late to be absorbed, it may be due to the intestinal peristalsis accelerated in the farting process, and bring out the situation of thin stools. 2. Acute enteritis: When acute enteritis occurs, the intestinal absorption of water may be weakened, resulting in more water in the intestinal contents. If you fart at this time, due to more water in the intestinal tract, the stool will not be shaped and may bring out thin stools. 3. Anal sphincter relaxation: the anal sphincter has the ability to prevent intestinal contents from being discharged. If the anal sphincter relaxes, the constraints on intestinal contents may be weakened, which may lead to thin stools when farting. There are other reasons for farting with thin stools, you should consult a doctor in time, improve the examination, clarify the cause and diagnosis, and standardize the treatment under the guidance of the doctor.
