are hemorrhoids dangerous,Doctor, am I suffering from rectal cancer?

    I was in the outpatient clinic last Thursday and I ran into a middle-aged female patient who came to my outpatient clinic with nervousness and tears, "Doctor, it's not good, I might have a rectal tumor. What should I do? Save me. Well, I'm...", it wasn't that I interrupted her, she might still be eloquent and eloquent, and continued to complain, I quietly asked her lover who stood silently: "She Do you usually have brain problems?", "No---, it's just that she has blood in her stool these few days, but she asked Du Niang herself, hey, it's all--it's all caused by the Internet," he answered categorically. I understood in an instant, I smiled helplessly, cleared my throat and said loudly to the patient: "According to the symptoms you said, I'm sure it is bleeding from the stool caused by hemorrhoids. You are scaring yourself.

    It seems that I really have to learn about blood in the stool with the readers, and hope that I will never encounter such a "God" in the future.

    What is blood in the stool? : The digestive tract (including empty, ileum, colon and rectum) below the ligament of flexion is called the lower digestive tract. Bleeding caused by the lesions in the above-mentioned parts is called blood in the stool, which is manifested as blood being discharged from the anus, or the blood is discharged with the stool, and the blood is mostly bright red or dark red. If the lesion is in the empty, ileum or right colon, and the amount of bleeding is less, the bleeding rate is slower, then black stool (tary stool) can be discharged.

    Hemorrhoids: Blood in the stool occurs during or after defecation, the blood is bright red, the blood does not mix with the stool, and the amount of bleeding can be large or small.

    Anal fissure: Blood in the stool caused by it is also common clinically. The blood is bright red, drips or wipes the blood with toilet paper, and severe pain in the anus after the stool.

    Rectal tumors: The blood in the stool caused by this type of disease is similar to hemorrhoids. The blood in the stool is bright red and is attached to the surface of the stool in drops. There may be mucus in the stool, and blood, mucus, and stool are often mixed. The late stage is accompanied by anorectal fall and body weight loss, increased stool frequency, constipation and diarrhea alternately, and may be accompanied by thinning of the stool and/or grooves on the stool surface.

    Rectal and colon polyps: painless stool bleeding. Bleeding during defecation, and stop after defecation, the amount varies. Generally, blood does not mix with feces, or polyps are high in position and large in number, and can also mix with feces.

    Ulcerative colitis: Ulcerative colitis causes blood in the stool, mostly mixed with mucus or pus and blood in the stool, accompanied by lower abdominal pain, fever, frequent stools, and tenesmus.

    my point of view

    If there is blood in the stool and the amount of blood in the stool is large and lasts for a long time, please consult a doctor in time. After arriving at the hospital, listen to the opinions of experienced specialists, and if necessary, improve relevant laboratory tests to clarify the cause: stools without gross blood but occult blood can be checked for fecal occult blood test. Laboratory tests: including liver and kidney function, electrolytes, blood sugar, blood lipids, coagulation function, tumor markers, etc. Imaging examinations: abdominal ultrasound, CT, MRI, gastrointestinal endoscopy, capsule endoscopy, etc. to determine the location and nature of digestive tract lesions; bone marrow puncture examination, except for blood system diseases; digital anus examination helps to find rectal tumors.

    After understanding the above-mentioned possible causes of blood in the stool, I believe that if you encounter blood in the stool, you will not panic again. As a "plumber" in the digestive tract, I remind everyone that he must first understand that blood in the stool itself is not a disease, but just a certain Symptoms of these diseases. Generally speaking, colon polyps, intussusception, Meckels diverticulum and inflammatory diseases are common causes of blood in the stool in children and adolescents; middle-aged and elderly patients have intestinal inflammatory diseases, Colon, rectal cancer, and intestinal vascular diseases are common causes; perianal diseases such as hemorrhoids, anal fissures or fistulas should not be ignored in adults.
