According to its symptoms, irritable bowel syndrome usually belongs to the category of “diarrhea” in traditional Chinese medicine, which is not caused by the weakness of spleen and stomach, but mainly has the evidence of liver qi stagnation (poor qi and blood transportation of the liver and depression), spleen and stomach weakness, dampness-heat condensation (the accumulation of dampness and heat in the body), and renal yang deficiency (deficiency of yang qi in the kidney). 1. Liver qi stagnation (poor transportation of qi and blood in the liver, emotional depression) syndrome: mainly due to excessive depression, anger and sorrow, resulting in a loss of regulation of the liver and a loss of qi, which leads to qi stagnation and blood stasis (stagnation of blood due to lack of qi), and impassability of the veins and channels and results in abdominal pain. 2. Weakness of the spleen and stomach: due to various reasons, the spleen and stomach are weak, dysfunctional, dietary water and grains can not be converted into essence, which causes internal obstruction of dampness and turbidity (dampness and turbidity blocked in the body), and turbidity and clearness are not differentiated and mixed, which can cause diarrhea. 3. Damp-heat accumulation (dampness and heat in the body of each other) evidence: addicted to fatty and spicy things, gastrointestinal heat, damp-heat evil condensation in the intestinal tract, visible mucus, diarrhea; if there is injury to the Jin chemical dryness, intestinal loss of moistening, bowel gas does not smooth constipation; so there may be diarrhea and constipation alternately. 4. Kidney yang deficiency (deficiency of yang qi of the kidneys): Kidney yang is not warm, the spleen is not warm, transport and transformation is not normal, water and grain are not transformed, elevation disorders (the function of qi up and down abnormalities), resulting in diarrhea caused by the lack of separation of turbid and clear. If you have symptoms related to irritable bowel syndrome, it is recommended that you go to the hospital and choose the appropriate treatment plan after the professional Chinese medicine practitioner has clearly identified the symptoms.
