Too thick stool may be caused by physiological factors and pathological factors (such as constipation and intestinal dysfunction). 1. Physiological factors: may be caused by diet, if you eat too much food containing protein and fat, and dietary fiber intake is too little, intestinal peristalsis will be slow, the feces in the intestinal tract will stay for a long time will be relatively thick, so there will be the phenomenon of too thick stools, which is a normal physiological phenomenon. 2. Pathological factors (1) Constipation: It is mainly due to the slow peristalsis of the stomach and intestines after the patient’s illness, which leads to the reduction of water in the stool, and the stool in the body can not be discharged from the body in time, and it will pile up in the anus, and then form the thicker stools, so there will be the phenomenon of too thick stools. (2) Intestinal dysfunction: It is mainly due to the dysfunction of the autonomic nervous system that governs the movement of the intestines, which leads to uncoordinated intestinal movement, and food cannot be digested and absorbed in the gastrointestinal tract, thus leading to the phenomenon of too coarse stools. If the phenomenon of too thick stools, it is recommended to consult a doctor in a timely manner, under the guidance of a doctor to identify the cause of the disease, so as to avoid delays in the condition of the targeted treatment.
