Nowadays, life is good, the day is more and more prosperous, eating is more and more fine, high protein, high fat food more, less vegetarian, work is busy, more pressure, exercise time is gone. All the reasons together, constipation came. According to statistics, the incidence of constipation is increasing year by year, constipation is becoming more and more common. The relevant data reflects, constipation disease Europe and the United States higher than Asia, developed countries higher than developing countries, urban higher than rural. China’s population prevalence of constipation between 2% to 28%, Beijing, Tianjin, Xi’an, more than 60 years old people survey, chronic constipation as high as 15% to 20%. Constipation, generally speaking, is less than 2~3 times per week, accompanied by difficulty in passing stools, less stools and dry and hard. Chinese medicine says “if you can’t pass it, it hurts”, so what is the result of not passing stool? Long-term accumulation of stool in the intestine, a variety of toxins and intestinal contact time is extended, toxin absorption increases, fire, acne will occur, serious toxin damage to various organs, aggravate the detoxification burden on the liver, and may even lead to intestinal cancer in the long term. The stool is dry and hard, difficult to solve, on the heart and cardiovascular elderly, it may trigger heart failure, heart attack, cerebral infarction and other fatal problems; even for young people, long-term constipation, defecation, hemorrhoids came, the serious may affect sexual function. In addition, the stool does not pass, will also increase the psychological burden. Causes of constipation, in addition to the above mentioned bad habits, most of the functional constipation, that is, the human nervous system, gastrointestinal tract dysfunction caused by constipation. In addition, there are also drugs, other systemic diseases such as diabetes, scleroderma and long-term bedridden and other reasons. However, among the causes of constipation, a large part is caused by organic lesions of the gastrointestinal tract, such as colorectal cancer, adult megacolon, colonic weakness, rectal proptosis, rectal mucosal intussusception, pelvic floor muscle spasm and so on. This part of the organic pathology is potentially directly fatal, but is also capable of surgical cure. Many patients with constipation, many of whom had used laxatives such as detoxification and purgatives until they became ineffective with them came back to the hospital. We performed colonoscopy on them and found that the colon was already black with lesions. It must be pointed out here that most of the patients with constipation, especially functional constipation, can be cured if diagnosed and treated correctly at an early stage, but once taking laxatives containing anthraquinones for a long period of time, the colon is prone to black lesions, and at this time, the colon has no function. Moreover, the black lesion of the colon will easily cause polyps to grow in the colon, which is a kind of pre-cancerous lesion, and the chance of cancer will increase. Constipation diagnosis and treatment is a gradual process, long-term constipation or sudden constipation for more than one month, it is necessary to go to the hospital for colonoscopy, colon transport test, fecal imaging, anorectal power test, first of all, to exclude tumors, adult megacolon, and other organic lesions. If it is indeed functional constipation, its treatment is also graded. For those caused by bad living habits, it can be recovered by improving living habits. Colon hydrotherapy can be used, which is different from the traditional enema method, is a kind of “clean up first, conditioning for the latter, slow and fast treatment, no medicine and cure” thorough colon cleaning method. By the strictly professional training of physicians, the reverse osmosis, filtration, disinfection of pure water and special agents, through the soft, lubricated special, disposable tubes easily injected into the colon, safe, less painful, non-infectious. For tumors, megacolon, colon weakness and other organic lesions, surgery is required.
