Stools that do not pass usually do not turn into fat. Stools that do not pass are considered to be related to indigestion, ulcerative colitis and other factors. When the human body consumes too many calories, the body will gradually turn them into fat after absorbing them, and the fecal matter usually does not turn into fat, but the long time that the fecal matter can’t be discharged normally may lead to a gradual increase of toxins in the body, which will have a negative impact on the metabolism of fats. Indigestion can lead to the food in the intestines can not be properly digested, and will accumulate in the intestines, causing the phenomenon of not passing stools. Colitis is due to the presence of inflammatory stimulation around the colon, so that there is a certain amount of inflammation or ulcers in the intestinal mucosa, resulting in weakened peristalsis, which in turn leads to the symptoms of failure to pass stools. If the phenomenon of not being able to pass stool, you should go to the hospital in time to avoid delaying your condition.
