As the saying goes, “nine out of ten people have hemorrhoids”, which means that there are quite a lot of people suffering from hemorrhoids. The main symptom of hemorrhoids is fresh blood after a bowel movement or a swelling coming out of the anal opening. The bleeding can be in all stages of internal hemorrhoids, and the bleeding can be as little as fresh blood on the stool or blood on the paper when defecating, or as serious as drip bleeding or jet bleeding, which can be secondary to hemorrhagic anemia if not taken seriously for a longer period of time, and can cause dizziness and weakness, pallor, and shortness of breath and panic when going up stairs, which can seriously affect the quality of life. Recently in the clinic met a female patient, 30 years old, white-collar company, has repeatedly stool blood for more than half a year, has not been paid attention to, usually often use hemorrhoid cream, hemorrhoid suppositories, the symptoms are sometimes light and heavy. Recently, the company often work overtime, busy work, blood in the stool gradually aggravated, more than a week of continuous blood in the stool, often in the form of jet bleeding, they used the hemorrhoid suppositories also did not see relief, one day suddenly fainted in the company, colleagues rushed to the hospital, after detailed examination and anorectal consultation, check the hematocrit 74g / L, anemia is serious, anal microscopy can be seen on the dentate line mucosa is moderate or heavy elevation, of which 11 points is the largest. The deglossoscopic observation could see bleeding spots on the nucleus of hemorrhoids with jet bleeding. The final diagnosis was: hemorrhagic anemia secondary to mixed hemorrhoids. The patient was discharged from the hospital five days later for rest and recuperation, and after one month, the patient recovered well and did not have blood in the stool, and the hematocrit also rose to 90g/L. Therefore, the majority of friends should also pay attention to whether there is blood in the stool after the operation. If you have blood in the stool, you should pay attention to the following points: 1. Pay attention to the characteristics of blood in the stool (1) distinguish between the nature of blood in the stool, color, bleeding mode and bleeding volume. If the internal hemorrhoid bleeding is bright red, manifested as paper wipe with blood, dripping or jet bleeding; if more bleeding, blood in the intestinal cavity storage, discharge can be black, consider the upper gastrointestinal tract lesions; if purple, dark red or blood clots are mostly from the lower gastrointestinal tract; mixed with mucus and odor, should think of the possibility of rectal malignancy. (2) Understand the process of occurrence and development of blood in stool. Internal hemorrhoids and anal fissures often bleed after defecation; chronic non-specific colitis and colon polyps often present recurrent, intermittent small amounts of blood in the stool; mid- to late-stage (colonic) rectal malignancy can be persistent small amounts of blood in the stool. 2, pay attention to the accompanying symptoms of blood in the stool, such as proctitis, rectal polyps (cancer) and other blood in the stool is often accompanied by anal cramps, shortness of breath; internal hemorrhoids, polyps blood in the stool without anal pain; anal fissure is accompanied by anal pain and constipation; chronic colitis is often accompanied by diarrhea, vague pain in the left lower abdomen; hemorrhagic necrotizing colitis, intussusception with severe abdominal pain or even shock, etc. Reminder: hemorrhoids blood in the stool is not terrible, as long as timely medical examination can be clearly diagnosed, a variety of treatment can also make the condition improve or cure.
