Tummy pain, farting and unshaped stools may be caused by indigestion, irritable bowel syndrome, enteritis, intestinal tumors and other reasons. 1. Indigestion: stomach peristalsis is slow, food stays in the stomach for too long, after fermentation, gas production increases, which can cause more gas, abdominal pain, and not fully digested food is discharged into the intestinal tract, stimulating intestinal peristalsis to accelerate, resulting in unshaped stools. 2. Irritable bowel syndrome: stress, tension, anxiety and other reasons can induce irritable bowel syndrome, causing abnormal bowel movements, resulting in abdominal pain, gas, stools are not shaped. 3. Enteritis: when the intestinal tract is infected by pathogenic bacteria such as bacteria and viruses, it can also lead to abdominal pain, hyperventilation and irregular bowel movements. 4. Intestinal tumor: such as rectal cancer, colon cancer can cause changes in the nature and frequency of stools, accompanied by abdominal pain, frequent gas, anemia, weight loss and other symptoms. It is recommended to consult a doctor in time to find out the cause of the disease under the guidance of a professional doctor and follow the doctor’s instruction to avoid delaying the condition.
