Possible signs of intestinal obstruction in the elderly are abdominal pain, vomiting, progressive abdominal distension, and cessation of anal defecation. 1. The abdominal pain of intestinal obstruction is severe, usually paroxysmal colic, if it is severe persistent abdominal pain, we should be alert to the possibility of strangulation intestinal obstruction, please consult a doctor in time. 2. Vomiting may occur in intestinal obstruction, and the vomit may be a mixture of gastric juice and food, or fecal matter. If the vomit is bloody, the possibility of strangulation is high, so please consult a doctor promptly. 3. Intestinal obstruction is also accompanied by progressive abdominal distension and cessation of anal defecation. 4. Elderly patients are different from young patients in that they have poorer physical ability to respond, and sometimes they may have very serious illnesses, but the clinical symptoms are very mild. 5. A part of elderly patients may have the feeling of urgency and heaviness at the anal opening (discomfort in the lower abdomen, wanting to relieve stool, feeling of incomplete defecation after defecation), wanting to defecate but not having stool, or having mucus discharge, which often suggests that intestinal tumors cause obstruction with a higher possibility. 6. If the elderly patients have a history of abdominal surgery, the possibility of obstruction caused by intestinal adhesions is also greater. If the above symptoms occur in the elderly at home, please consult the doctor in time and standardize the treatment under the guidance of professional doctors to avoid delaying the condition.
