The main cause of diarrhea is still to consider the possibility of acute gastroenteritis. However, it is also largely related to one’s own state, such as deficiency of spleen qi and lack of lifting power, and too cold diet, which can lead to diarrhea. Diarrhea is one of the main symptoms of acute gastroenteritis, in addition to a series of systemic symptoms such as nausea, vomiting, loss of appetite, headache and fever. This condition often occurs after eating food contaminated with bacteria, viruses and other pathogenic microorganisms. It can also be caused by the long-term application of antibiotics, and the intestinal tract is irritated, intestinal flora imbalance, intestinal peristalsis accelerated and symptoms such as diarrhea. Adverse emotional stimuli, such as sudden stress, anxiety and panic, can also induce the occurrence of symptoms such as diarrhea. In addition, if the patient has a weak spleen qi and a deficiency of spleen yang, the patient’s own power of lifting is insufficient and the middle qi is sunken, so if the patient is slightly stimulated by cold, diarrhea will easily occur. Cold will also make smooth muscle spasm contraction, fruit is mostly cold, long-term eating fruit is also easy to defeat the stomach and the symptoms. All in all, the main thing to consider is the gastrointestinal disease and their own eating habits and living conditions, such as spleen qi weakness, spleen Yang deficiency and cold attack.
