The causes of loose stools include poor diet, weak spleen and stomach, and cold and dampness trapping the spleen. 1. Dietary irregularities: when the human body does not eat regularly and is in a state of hunger and satiety, it will damage the spleen and stomach; if it is in such a state for a long time, it may lead to impaired digestion and absorption, and then the stools will not be solid. 2. Weakness of the spleen and stomach: when the spleen and stomach of the human body are weak, there may be a lack of spleen qi and a decline in the function of transportation; the spleen and stomach are mutually exclusive, and when the stomach is weak, it may affect the spleen and aggravate the degree of spleen dysfunction, which may lead to the occurrence of stool inaccuracies in the human body. 3. Cold and dampness trapping the spleen: When cold and dampness trapping the spleen occurs in the human body, it will lead to cold and dampness within the human body (cold and dampness accumulation in the body), and because the spleen likes dryness and hates dampness, it will make the spleen lose its function of transportation, which may lead to the downward seepage of water and dampness, and then the stool is not solid. When the situation of insubstantial stools occurs, it is recommended that the patient go to the relevant hospital department for examination in order to clarify the cause and actively treat it.
