People with heavy dampness are prone to diarrhea, because Chinese medicine says that the spleen is responsible for transportation and transformation, and the characteristics of the spleen like dryness but hate dampness, i.e., the spleen likes dryness but hates dampness, so if dampness is heavy, it will affect the transportation and clearing function of the spleen, and the weakened clearing function of the spleen will lead to a decline in yang energy and diarrhea. However, not all diarrhea is caused by Spleen Qi deficiency or Dampness, it can also be caused by Damp-Heat internal stagnation, dietary stagnation or Liver Qi. It is recommended to find a professional Chinese medicine practitioner to use the appropriate treatment method to regulate the symptoms after clear identification of the type of symptoms, and it is not recommended to use medication without permission to avoid aggravating the symptoms and prolonging the course of the disease. In addition, people with heavy dampness should also pay attention to their diet, avoiding undigestible or spicy stimulating foods, which may aggravate the diarrhea symptoms.
