Chronic constipation is defined as a decrease in the number of bowel movements, less than 3 times per week, and/or poor bowel movements, straining, and dry stools. Chronic constipation can cause local and systemic symptoms. It can cause anal pain, anal swelling, anal fissures, perianal abscesses, and bleeding hemorrhoids due to excessively hard stools. Local irritation of fecal stones can cause damage to the intestinal mucosa and the formation of fecal ulcers. Fecal stones sometimes even have to be pounded out with instruments or dug out with fingers. In addition, metabolites and toxins in the intestinal tract can not be quickly discharged and retained in the body, which can cause systemic symptoms, such as bitter mouth, sticky mouth, epigastric distension, distension and pain in the two sides, belching, some patients may also have loss of appetite, depression, dizziness and weakness, general discomfort, headache, insomnia, etc.. Chronic constipation in the elderly is a cause of death in some acute cardiovascular diseases. For example, the elderly mostly have hypertension, atherosclerosis, coronary heart disease, constipated patients often need to mobilize the whole body to expel stool, increased abdominal pressure or excessive force to increase blood pressure, heart rate, increased myocardial oxygen consumption, increased cardiac load. Elderly patients with constipation due to defecation sitting or squatting for a long time, coupled with excessive force can appear dizziness, fatigue, panic, shortness of breath, sweating and other symptoms, can induce defecation syncope, increased blood pressure, insufficient blood supply to the brain, and even cerebrovascular rupture, can also induce angina, and even acute myocardial infarction, arrhythmia, aortic aneurysm or rupture of the heart ventricular wall aneurysm and sudden death. This is the biggest threat to the elderly and should be alerted. Therefore, for the above patients, especially for patients with acute myocardial infarction, straining to defecate should be contraindicated. Chronic constipation in the elderly plays an important role in the occurrence of many diseases, such as bacterial fermentation in food residues, producing a large number of harmful gases and toxins, if not discharged in time, toxins are absorbed by the blood, which can affect health and life expectancy. When these toxic substances exceed the detoxification capacity of the liver, can enter the brain with the blood circulation, thus damaging the central nervous system, so that the normal function of the brain nerve abnormalities, the elderly can lead to senile dementia. If constipation is not lifted for a long time, it can lead to fecal incomplete intestinal obstruction or even complete intestinal obstruction. Dry stool carcinogenic substances on the intestinal mucosa long-term stimulation, can induce colon and rectal cancer. Diabetic patients with constipation cannot eat normally because it affects gastric emptying, which makes blood sugar fluctuate greatly and is not easy to control. In elderly men with constipation, fecal matter in the rectum presses on the enlarged prostate gland, causing frequent urination and difficulty in urination, which increases the bladder capacity and forms urinary retention. Due to the effort of defecation and dysfunction of the anal sphincter, the rectal mucosa of constipated patients tends to partially or completely prolapse out of the anus, resulting in rectal prolapse. In short, long-term chronic constipation induces and aggravates a variety of diseases, which brings great burden and pain to the elderly psychologically and physically and affects their life and health, so it should be highly alert, early prevention and treatment.
