A small amount of black coffee will not cause constipation, but a large amount of black coffee may lead to constipation and affect the body, due to the different physical condition of the patients, so the specific situation varies from person to person,
Black coffee contains a large amount of caffeine and theophylline, moderate consumption of black coffee may lead to nervous system excitement, and stimulate the secretion of gastric acid, which can effectively promote gastrointestinal peristalsis and help patients defecate. In addition, if patients drink a large amount of black coffee for a long time, it may lead to constipation, rapid heartbeat, gastrointestinal discomfort and other symptoms.
Since patients’ gastrointestinal digestive ability varies, it is recommended that the amount of black coffee consumed should be controlled, and it is recommended that patients should drink warm water in moderation and do more physical exercise, which can help relieve constipation.
