Loose stool may be related to physiological factors or pathological factors, such as indigestion, enteritis, intestinal cancer, and need to be treated according to different causes. 1. Physiological factors: Due to eating too much crude fiber food, the stool will be accompanied by a large amount of food residue, and then there will be the phenomenon of loose stool, but there are no other uncomfortable symptoms. It can be relieved by improving dietary habits. 2. Pathological factors: (1) Indigestion: Eating hard-to-digest food or eating too much can cause indigestion, in which the food cannot be fully digested and absorbed, and the phenomenon of loose stools can also occur. Medications such as mosapride tablets and domperidone tablets can be used under doctor’s guidance to promote intestinal peristalsis and relieve indigestion, thus improving symptoms. (2) Enteritis: When the intestines are attacked by bacteria, viruses and other microorganisms, it will lead to enteritis, which can also occur in the phenomenon of loose stools, accompanied by abdominal pain, vomiting, nausea, abdominal ringing and other symptoms. Patients can use antibiotics such as cephalosporins and levofloxacin under the guidance of doctors for treatment. (3) Bowel cancer: Bowel cancer patients may also have the phenomenon of loose stools, usually accompanied by blood and pus in stools, abdominal pain, abdominal mass and other symptoms. Bowel cancer patients should undergo surgical resection with radiotherapy and chemotherapy under doctor’s advice. If the phenomenon of loose stool excludes physiological factors and still exists, it is necessary to consult a doctor for examination in a timely manner, so as to clarify the cause of the disease and treat it actively under the guidance of a professional doctor.
