Common causes and treatments 1, eating too much: spinach is rich in dietary fiber and vitamins, after consumption can play a role in promoting gastrointestinal motility, help digestion, absorption. When an excess of spinach is used, it can lead to faster gastrointestinal peristalsis, which in turn causes diarrhea. Usually stop using it to relieve the symptoms; 2. Spinach contamination: common when cleaning spinach is not thorough, resulting in bacteria and pesticides still remaining on the surface. Acute enteritis can be triggered after consuming unclean spinach, thus causing symptoms such as abdominal pain, increased number of stools, and mucus-purulent stools. The patient should promptly seek medical attention and follow medical advice to choose antidiarrheal treatment, but also need to use antibiotics anti-inflammatory treatment as appropriate; 3, gastrointestinal dysfunction: spinach is cold, if the gastrointestinal function of a certain obstacle, can be rich in potassium ions in spinach to promote gastrointestinal peristalsis, resulting in increased defecation, but also because of the gastrointestinal absorption function is weakened, resulting in the inability to absorb rich nutrients, leading to indigestion, and then cause diarrhea. In this case, under the guidance of a professional doctor, the use of drugs such as gastric su granules to promote gastrointestinal peristalsis, can also use drugs to help digestion or release gastrointestinal spasm to relieve symptoms.
