A, elderly constipation performance: dry stool, defecation difficulties, defecation interval up to 3-10 days, accompanied by varying degrees of dry mouth and tongue, back pain and leg weakness, dizziness and weakness, less abdominal distension and other performance. Constipation is a common pathology in elderly patients, and a survey shows that the prevalence of constipation among the elderly in China is 15%-30% or more, and the high incidence has a great impact on the life of the elderly. Constipation often requires forceful breath-holding due to difficulty in defecation, causing strong contraction of the abdominal muscles, resulting in increased pressure in the abdominal cavity, and when the abdominal vessels are subjected to certain pressure, a large amount of blood will flow back to the heart, resulting in increased burden on the heart and increased blood pressure. In some critical illnesses such as acute heart attack, acute cerebral hemorrhage, severe hypertension patients, constipation caused by forceful defecation increased abdominal pressure, the sudden increase in intravascular pressure and caused sudden death are numerous. Second, Chinese medicine dialectical treatment: the dialectical evidence of the disease and the doctor’s understanding of the disease is closely related, because the doctor’s understanding of the pathogenesis of constipation varies, so in the identification and treatment is not consistent. Some people believe that “no water boat stop” is the basic pathogenesis of constipation in the elderly, so it is necessary to increase the liquid to move the boat, nourish blood and moisten dryness treatment; some people believe that spleen deficiency and weakness of transportation is the fundamental cause of constipation in the elderly, so the main treatment is to benefit the qi and strengthen the spleen; some people believe that the elderly are mostly due to deficiency of kidney yuan, the vital gate fire failure, can not warm the yang to transform the qi and drumming weakness, intestinal bowel movement is insufficient qi The treatment should be to warm the Yang and open the bowels. In fact, the elderly is like a machine that will age after a long time, after middle age, as people grow older, the function of human organs is constantly declining. The classic work of Chinese medicine “Huang Di Nei Jing” has this record, “people over forty and Yin Qi since half”, meaning that after the age of forty body functions begin to decline, the body’s Qi, blood, Yin and Yang began to deficiency. Therefore, constipation in the elderly is mostly caused by deficiency of qi, blood, yin and yang. For this reason, the treatment should be based on tonicity, in order to complement but not stagnate supplemented with herbs that move Qi and activate Blood. As a reminder, constipation in the elderly should never be treated with laxatives, because the gastrointestinal tract of the elderly is already weak, the use of laxatives is not only easy to make the elderly more than diarrhea, but also easy to make the gastrointestinal tract of the elderly more weak, aggravating constipation.
