Patients with cerebral infarction keep defecating, which may be related to gastrointestinal nerve dysfunction, central lobule location infarction and other factors, it is recommended to conduct head CT, stool routine and other examinations under the guidance of doctors to clarify the cause and treat the cause. 1. Gastrointestinal nerve dysfunction: patients with cerebral infarction will combine different degrees of gastrointestinal nerve dysfunction, and those with serious conditions will have non-stop defecation. It is recommended to give montelukast, bifidobacterium and other drugs to adjust the intestinal flora and improve the symptoms; 2. Central lobule location infarction: brain edema is caused after brain infarction, resulting in increased intracranial pressure, especially in patients with large brain infarction, the increased intracranial pressure will stimulate the parasympathetic center of the central lobule. The central lobule is the center of stool control, so if there is a brain infarction or if it is stimulated or damaged, it is easy to cause poor stool control and symptoms such as incessant bowel movements or inability to pass stools. General anti-diarrheal and flora-regulating drugs are ineffective. Active treatment is needed for cerebral infarction, and only when the condition of cerebral infarction is improved will the situation of incessant bowel movements improve.
