Constipation is not a specific disease, it is a symptom of many diseases. Constipation have mild and severe, in the time may be temporary and long-term. As a result of constipation caused by many factors, but also very complicated, so, in the event of constipation, especially more serious, longer duration of constipation, patients should check in time to the hospital to find the causes of constipation, in order not to delay the original disease diagnosis and treatment, not to abuse laxatives.
Constipation is reduced defecation frequency, every 2 to 3 days or even longer time, irregular, stem fecal hard, often accompanied defecation difficulties. Some of the normal number of bowel movements a genius, but no discomfort, this is not constipation. Constipation can be divided into two types of acute and chronic. Acute intestinal obstruction from constipation, intestinal paralysis, acute peritonitis, acute cerebrovascular disease, accidents and so on; more complex causes of chronic constipation in general may be no obvious symptoms. By the incidence of site classification, can be divided into two types:
1. colon constipation. As the colon inside and outside of the mechanical obstruction caused by constipation constipation referred to as mechanical. Peristalsis as a result of binding or loss of function of the constipation caused by constipation can not call it. As a result of intestinal smooth muscle spasm caused by constipation spastic constipation call.
2. rectal constipation. Mucosa as a result of reduced receptor sensitivity lead to the accumulation of fecal matter in the rectum. In rectal cancer, perianal disease. Habitual constipation were more common in middle-aged women and the middle class.
Constipation is not a long-term drug treatment would cause serious harm to the human body. Long-term constipation because the body will be severely hampered detoxification. Or even impossible because of the long-term detoxification and constipation coma or even death. Ordinary food into the stomach, after digestion and absorption will eventually excreted fecal residue into approximately 24 ~ 48 hours, generally between two stools should be 1 to 2 days. However, since everyone's circumstances vary, bowel habits can be significantly different, and some people daily or 2 to 3 days of stool 1, there are some stools a day 2 or 3 times, although the frequency of defecation interval or different, but as long as the stool not rare, non-drying scleroma, defecation is not easy, are normal.
If for some reason, so that feces stay in the large intestine for too long, contained in faeces was excessive absorption of moisture, become dry hard stool, accompanied by defecation time when it would be difficult for discharge, pain, or give rise to the abdominal distension, abdominal pain, and more wind, loss of appetite, dizziness, weakness and other symptoms, the normal rules of disruption of defecation, reduction in the number of defecation, time interval, severe cases, such as emissions from sheep feces stool samples was small spherical granules. If the number of weekly bowel movements less than 3 times, and difficulties with defecation obvious that this situation is known as constipation.
Constipation in the elderly can be divided into colon and rectum constipation constipation. The elderly do not sound teeth, eat a low-hi slag fine food, and thus the lack of stimulation of cellulose on the intestinal wall, so that the functioning of the colon of stool time; In addition, fewer older people movement, intestinal muscle contractility in the general decline in the colon are easily led to constipation . The elderly and the levator ani muscle weak external anal sphincter relaxation, resulting in fecal impaction by rectal fossa rectal constipation.
Constipation can also be caused by perianal diseases such as hemorrhoids, fistula, colon, caused direct hernia. Some of iron, aluminum, calcium preparations may also cause constipation.
As a result of habitual constipation, patients are often long-term use laxatives, which can lead to intestinal dysfunction. Prevention of constipation should eat more vegetables, the treatment of perianal disease and, where appropriate, drug use purge.
