Constipation refers to difficulty or effort in defecation, poor bowel movement, reduced frequency of defecation, and low volume of dry stool. Surveys show that constipation is as high as 15% to 20% in elderly people in China, with more women than men, and the prevalence increases significantly with age. The symptoms of constipation may vary depending on the type of constipation and the duration of the disease, but the main symptoms are defecation less than 3 times a week, difficulty in defecation, long defecation time, dry stool like sheep stool and small amount of stool, feeling of incomplete defecation after defecation, bad breath, nausea, swelling and pain in the lower abdomen, abdominal distension, loss of appetite, fatigue, dizziness, irritability, anxiety, insomnia and other symptoms. Some patients may have anal pain, anal fissure, hemorrhoids and anal papillitis due to forceful discharge of hard stool. Strip-like masses can often be palpated in the left lower abdomen in the sigmoid colon area. Because constipation is more common and the symptoms vary in severity, most patients think that constipation is not a disease and do not seek treatment, but there are times when constipation is still very harmful. Especially if it is accompanied by blood in the stool, anemia, wasting, fever, black stool, abdominal pain and other symptoms, you should go to the hospital as soon as possible for further examination. Therefore, patients with constipation, whose symptoms manifest mostly as described above, usually do not lead to serious consequences, but still need to be brought to the attention of patients to avoid delaying important conditions.
