The incidence of habitual constipation in the elderly is about 15%-30%, which not only affects the daily life of the elderly and brings pain and annoyance, but also has adverse effects on cardiovascular and cerebrovascular diseases and other systemic diseases, and even causes serious adverse events such as myocardial infarction, sudden death, and cerebral hemorrhage, which are increasingly attracting great attention. Constipation in the elderly is mostly caused by deficiency of yin and blood and lack of vital energy, resulting in the loss of intestinal moistening or the failure of the passages to descend, thus causing constipation. Although this condition is common, patients often complain that their stools are not dry and hard, but they have poor bowel movements, or they struggle with weakness, and they are short of breath and weak after defecation. The spleen and stomach are located in the middle of the state and are the hub of the three jiao lifts. If the spleen and stomach are healthy, and the lift is as normal, there will be no obstruction to food and bowel movement; on the contrary, if the spleen and stomach are deficient in qi and the lift is out of order, the large intestine will not be able to transmit, and the stool will not be dry, but the bowel movement will be weak or not smooth. In general, doctors tend to use laxatives for daily treatment, which are easy to take and accepted by patients. But because the laxative medicine consumes gas and injures fluid, often make constipation more stubborn and persistent, diarrhea too violent or old and frail people may also lead to elderly patients with more than diarrhea, incontinence, and even dehydration. The author believes that the treatment of constipation in the elderly should be based on the physiological and pathological characteristics of elderly patients, when the use of Qi to strengthen the spleen in order to strengthen the power of transport and descending, coupled with the method of nourishing Yin and moistening the intestines, through the tonic for the pass, pass in the tonic, can achieve the effect of laxative without harming the right.
