It should not be normal for an adult to poop three or four times a day. Generally, it is normal for adults to have one to two bowel movements a day or one to two days, while three or four bowel movements a day should not be normal. Common causes of this condition include cold stomach, indigestion and digestive tract infection. 1. Stomach cold: because adults stir the quilt at night, daytime gluttony cold drinks or clothing is not warm enough and other reasons caused by the stomach cold, may stimulate the gastrointestinal tract abnormal contraction, peristalsis accelerated, the phenomenon of three or four times a day will occur. 2. Indigestion: If the adult eats high cholesterol, high protein or high starch food, causing indigestion, and cannot digest and absorb all the food in time, he/she may have bowel movements three or four times a day. 3. Digestive tract infection: If the digestive tract is infected by pathogenic bacteria and triggers intestinal infectious diseases, the pathogens will stimulate intestinal spasms and increased intestinal secretion, so there will be a situation of having bowel movements three or four times a day. If adults always have bowel movements three or four times a day, they should go to the hospital for consultation and treatment to avoid delaying their condition.
