But a few days ago, Xiaodong's old father added a new problem, that is, the stool is dry, and sometimes it takes 4 or 5 days to solve the stool, which is particularly difficult. I haven't defecated once a week these days, which leads to obvious swelling and pain in the lower abdomen, which makes the elderly fidgety and seriously affects their normal life. Xiaodong bought medicine for diarrhea for his father, discharged a little sheep dung-like stool, and abdominal distension remained. Three hours later, the old man went to the bathroom again. Suddenly, the old man had blood in his stool, and the amount of blood in his stool was very large. The old man suddenly felt dizzy and fell in the bathroom. Fortunately, Xiaodong found out in time and immediately sent the old man to the hospital for treatment. Help the elderly get their lives back. So, why do old people have bloody stools soon after defecation? The symptoms of hematochezia after defecation by Xiaodong's old father do not rule out fecal impaction. Fecal impaction is a serious and special form of constipation. Because of long-term constipation, the feces are dry and accumulate into a solid block, which is blocked in the rectum and cannot be discharged by itself, which will cause serious constipation symptoms and perineal pain. It is a painful anorectal physiological disorder that needs the help of others or self-excavation. Once the patient's constipation is not treated in time for a long time, it is easy to cause fecal impaction. The main symptoms are severe abdominal pain, anal pain, rectal fullness, perineal discomfort and so on. This often makes patients fidgety, in a trance, unwell and extremely painful. If the patient has fecal impaction and is not treated in time and properly, the patient may have fecal ulcer perforation, leading to peritonitis, secondary rectal bleeding, dizziness, palpitation, cardiovascular and cerebrovascular diseases, and the treatment is not timely or even life-threatening. Fecal impaction generally occurs in the elderly, especially the elderly, patients who have been ill in bed for a long time or patients with chronic diseases such as diabetes. The reason of hematochezia is that the pressure in rectum is at a high level for a long time after constipation, which leads to fecal ulcer or erosion of rectal mucosa and sporadic bleeding, and the patient has a lot of bleeding after the fecal mass is peeled off. This kind of disease is characterized by sudden massive bleeding and bright red blood, and patients are often accompanied by blood clots after using various laxative methods. For patients with fecal impaction, massive rectal bleeding after fecal impaction is a common disease in anorectal department, which generally requires hospitalization, surgical suture to stop bleeding and antidiarrheal drugs to keep the stool normal. In order to prevent the recurrence of fecal impaction, patients should develop the habit of defecating regularly every day and eat more fiber-rich foods, such as bananas, sweet potatoes and spinach. Drink plenty of water, take part in physical exercise properly, and have regular abdominal massage to avoid long bed rest. (Author: Zhan)
