Mechanism of habitual constipation: habitual constipation belongs to the category of deficiency constipation in Chinese medicine. Yin deficiency, blood deficiency, yin deficiency, blood deficiency, or postpartum, yin and blood deficiency, or blood loss and sweating, injury and loss of blood, or old and weak, yin and blood deficiency, or over-eating spicy and dry heat, loss of yin and blood, can lead to yin deficiency and blood deficiency, blood deficiency, large intestine does not glory, yin deficiency, large intestine dry, intestinal tract loss of moist, dry stool, difficult to go down, and constipation. For example, the “Medical must read? Stool is not” said: “more elderly fluid dry, women after childbirth dead blood, and sweating to facilitate urination, after the disease blood is not restored, can be constipated.” The basic pathology of habitual constipation is a large intestine conduction disorder, and lung, spleen, kidney and other visceral dysfunction, the whole body is closely related to the strength and weakness of qi, blood, yin and yang. Mostly due to kidney deficiency, yin and yang deficiency, resulting in the spleen loss of health, Qi and blood biochemical lack of source, Qi and blood deficiency, fluid deficiency, large intestine dryness, no water is difficult to travel. Functional constipation is directly related to today’s fast-paced life, high mental stress, and changes in diet structure due to excessive consumption of fat and sweet. These causes can lead to the internal concentration of fire evil, depletion of qi and injury to fluid, conduction failure, coupled with the abuse of laxatives, resulting in the loss of qi and fluid deficiency, constipation more and more. Habitual constipation contraindications: constipation patients often take rhubarb, senna and so on, bitter cold laxatives are most likely to hurt the body’s vital energy, loss of fluids, so that the gas injury and intestinal peristalsis is weakened, fluid depletion and intestinal loss of moistening, over time, resulting in more diarrhea more constipation, do not take the stool can not be discharged on their own. The use of laxatives leads to excessive rectal emptying, long time does not produce stool intention, can also cause constipation aggravated. In 1982, Bartle suggested that colonic mucosal pigmentation was related to anthraquinone laxatives. The pigmentation of the colonic mucosa can be engulfed by colonic mucosal cells in the intestinal tract, but the pigmentation can disappear after 4 to 12 months of stopping laxatives. Long-term use of Bohi Rhamnoides, Senna, Oxalis, and Ma Ren Pills can cause this disease. Therefore, we should not use large doses in the treatment of habitual constipation, nor long-term use of steep diarrhea agents to prevent the depletion of Qi, blood and fluid, thereby aggravating the pathological basis of habitual constipation.
