Elderly people who cannot defecate are considered to be constipated, which may be caused by physiological factors such as prolonged bed rest, or pathologic factors such as intestinal obstruction and colon cancer.
1. Physiological factors: prolonged bed rest, sedentary and other factors can lead to the slowing down of intestinal peristalsis, fecal matter stays in the intestinal lumen for too long, causing dryness of stools, which results in defecation difficulties and other symptoms. Elderly people eat too little, resulting in intestinal cavity pressure is too low, can also cause constipation and other conditions.
2. Pathologic factors:
(1) Intestinal obstruction: intestinal tuberculosis, intestinal polyps, etc. can cause the contents of intestinal lumen can not pass through the intestines normally and smoothly, thus leading to symptoms such as partial or complete cessation of defecation and exhaustion, abdominal distension, nausea, vomiting, loss of appetite and weight loss.
(2) Colon cancer: It is a malignant tumor of the digestive tract of epithelial origin in the colon, which may occur with symptoms such as blood in stool, diarrhea, constipation, nausea, vomiting and anemia. Cancer tissues may partially or completely block the intestinal lumen, which may lead to situations such as difficulty in defecation or even inability to defecate.
If an elderly person cannot pass stool, it is recommended to consult a doctor in time for a clear diagnosis, and carry out targeted treatment under the guidance of the doctor.
