Blood in the stool but no pain

1. Details of the cause

1. Varicose vein theory believes that hemorrhoids are venous masses formed by congestion, dilation and bending of the venous plexus under the mucosa of the lower rectum and the skin of the anal canal.

2. The anal cushion migration theory holds that hemorrhoids were originally normal anatomical structures in the anal canal, namely the vascular cushion, which is a ring-shaped spongy tissue band 1.5 cm above the dentate line. Only when the anal cushion tissue becomes abnormal and is accompanied by symptoms can it be called hemorrhoids and require treatment. The purpose of treatment is to relieve symptoms rather than eliminate hemorrhoids. There are many factors that cause hemorrhoids, among which constipation, long-term drinking, eating large amounts of irritating foods and sitting or standing for long periods of time are the main causes.

2. Symptoms

1. Blood in the stool. Painless intermittent spotting is its characteristic, which is also a common symptom of internal hemorrhoids or mixed hemorrhoids in the early stage, blood in the stool. External hemorrhoids will not cause bleeding. In mild cases, there is blood in the stool or blood on the stool paper followed by dripping blood. In severe cases, there is spurting bleeding. The blood in the stool can often stop on its own after a few days, which is very important for diagnosis. If bleeding occurs repeatedly over a long period of time, anemia may occur clinically, which is not uncommon and should be differentiated from hemorrhagic diseases.

2. Painful feeling. Heavy pain is the main symptom of external hemorrhoids. When internal hemorrhoids or mixed hemorrhoids prolapse and become incarcerated, edema, infection, and necrosis occur, it often causes severe heavy pain.

3. Prolapse of hemorrhoids. Prolapse of hemorrhoids is the main symptom of middle and late stage internal hemorrhoids. In the late stage, the hemorrhoids enlarge and gradually separate from the muscle layer and are pushed out of the anus during defecation. In mild cases, the prolapse only occurs during bowel movements and the prolapse can return to normal on its own after bowel movements.

4. Itching. In the late stage of internal hemorrhoids, the hemorrhoids prolapse and the anal sphincter relax, and secretions often flow out. Due to the irritation of the secretions, there is often itching and discomfort around the anus, and even skin eczema, which makes the patient extremely uncomfortable.

Complications

1. Cause anorectal diseases. Hemorrhoids are like a fuse that can trigger a variety of anorectal diseases, such as anal fissure, anal fistula, etc. If hemorrhoids trigger other anorectal diseases and several symptoms coexist, it will be very difficult to treat and the recovery time will be prolonged, which will have the greatest impact on work and study. Although it will not cause much harm to the human body, it is the result that all anorectal patients fear the most.

2. It can easily cause anemia. Blood in the stool is the main symptom of hemorrhoids. Stage I internal hemorrhoids are in the early stages and bleed more frequently. Stage II internal hemorrhoids belong to the middle stage, and the bleeding may be more or less. Clinically, the majority of patients have internal hemorrhoids at stages I and II. Because the symptoms of stage I and II internal hemorrhoids are relatively mild, they are easily ignored by patients or treated conservatively. Over time, as the amount of blood loss increases, patients develop pale complexion, fatigue, dizziness, weakness, memory loss, and even blurred vision and tinnitus. Suddenly standing up after sitting or squatting for a long time can cause collapse or fainting, loss of appetite, abdominal distension, lower abdominal edema and other serious anemia symptoms.

3. It can easily cause gynecological inflammation. Due to the proximity of the anus and vagina, hemorrhoid bleeding or inflammation often leads to the massive multiplication of bacteria, which accidentally enter the vagina and cause various gynecological inflammations such as vaginitis, urethritis, cystitis, and adnexitis.

4. Causes long-term eczema around the anus. Due to the prolapse of hemorrhoids and relaxation of the sphincter, mucus flows out of the anus and irritates the skin, causing skin itching and anal eczema. In severe cases, it may even spread to the buttocks, perineum and clitoris, and local rashes, erythema, erosion, exudation, scabs and desquamation may occur.
