The reasons for the difficulty of defecation in cerebral infarction mainly include low intake of food, slowing down of gastrointestinal peristalsis, and change of life habits, and so on. 1. Eating less: if patients with cerebral infarction have difficulty in eating due to difficulty in swallowing, and take nutritional solution for a long time, the food residue generated by the patients is less, and the number of defecation will be reduced accordingly. 2. Gastrointestinal peristalsis is slowed down: some patients need to stay in bed due to their condition, gastrointestinal peristalsis is weakened, which can also cause defecation to be reduced or difficult, and a very few patients may even have intestinal obstruction. 3. Change of living habits: some patients with cerebral infarction are not accustomed to defecate in bed after they are bedridden, which may cause the phenomenon of not defecating for a short period of time. Difficulty in defecation of cerebral infarction may also be caused by other reasons, if the patient’s symptoms are serious or have not improved for a long time, he/she should consult a doctor in time, complete the relevant examination, and receive standardized treatment under the guidance of a doctor after the cause of the disease has been clarified.
