Sudden constipation may be related to dietary factors, gastrointestinal dysfunction, and so on, and can be relieved by adjusting lifestyle and taking medication. 1. Lifestyle adjustment: Constipation is usually caused by poor dietary habits in daily life, such as consuming too much food with high fat content and not eating vegetables. Therefore, in order to solve the problem of constipation, we should avoid the intake of food with high fat content, and eat more vegetables, fruits, coarse grains and other foods, which can promote gastrointestinal peristalsis, facilitate digestion, and help to excrete feces. 2. Medication: If necessary, you can use some drugs to promote defecation, such as magnesium sulfate, lactulose, keserol and other drugs, which can help improve the constipation. The above drugs are prohibited for those who are allergic to them, and they should be taken according to the doctor’s instructions. If the patient’s constipation symptoms are serious, or continue to see no improvement, it is recommended to go to the regular hospital in a timely manner, after clarifying the cause of the disease, under the guidance of the doctor for targeted treatment.
