The actual hemorrhoids are a common disease and a common disease, as the saying goes, “ten men have nine hemorrhoids”, for the name of hemorrhoids, perhaps we are not unfamiliar, but what exactly is hemorrhoids, how to know that you have hemorrhoids, it is not clear. The actual hemorrhoids are actually a lot of anal diseases, such as internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, anal fissures, anal papillary hypertrophy, anal warts, anal fistula, anal rectal cancer, etc. The clinical hemorrhoids only include internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, of which internal hemorrhoids are the main. The so-called internal hemorrhoid is a kind of venous tumor in which the venous plexus in the lower part of the rectum and the wall of the anal canal expands, bends and bulges into a mass. External hemorrhoids are swellings or skin tags that occur at the edge of the anus, sometimes accompanied by pain. Internal and external hemorrhoids occur together and are generally called mixed hemorrhoids. Hemorrhoids are not usually cancerous. You may have hemorrhoids if you feel a swelling coming out of your anus when you bleed during a bowel movement, or if you have a painful swelling outside your anus, a bulge at the edge of your anus, a moist anal opening, and increased discharge. In the early stage of internal hemorrhoids, there is only simple blood in the stool, or blood in the stool, or it may come out in drops, or in jets during the stool, and there is no other discomfort except blood in the stool, but it may cause anemia after a long time; in the middle stage of internal hemorrhoids, the swelling will come out of the anus during the stool, and it can return by itself after the stool, and it may occasionally see the discomfort of swelling in the anus; in the late stage of development, the swelling cannot be returned after the stool comes out, and it can be returned after resting for a while or by hand, or it may even come out when coughing, exerting or If the swelling does not return for a long time, local edema, congestion, embedded in the anus, resulting in severe pain and restlessness, this is commonly known as “embedded hemorrhoids”. If the imbedded hemorrhoid is too long, it can regenerate local necrosis, which makes treatment difficult. The first stage is the early stage of internal hemorrhoids, where bleeding is a prominent symptom, and the second and third stages are the middle and late stages of internal hemorrhoids, where the surface of the nucleus has fibrosis and prolapse is the primary symptom. External hemorrhoids are mainly raised swellings around the anus, and are generally classified into four types in clinical practice. The sudden anal swelling with severe pain due to constipation or straining during defecation is generally called thrombosed external hemorrhoid; the swelling, pain and increased secretion at the outer edge of the anus is called inflammatory external hemorrhoid; the soft mass at the edge of the anus, which is usually small but increases in size during defecation, may be varicose veins external hemorrhoid; the skin folds at the edge of the anus deepen and form a skin flap of different sizes is called connective tissue external hemorrhoid. The main symptom of external hemorrhoids is the occurrence of swelling at the anal verge, sometimes accompanied by itching, pain or foreign body sensation at the anal opening. The actual fact is that there are many symptoms that cause bleeding in the stool, such as colon cancer, colitis, dysentery, and anal canal disorders, etc. Don’t think that bleeding in the stool is hemorrhoids, and buy medicine for your own use without going to the hospital for examination and treatment. Some people are very nervous when they see blood in their stool, suspecting they have cancer and worrying about it all day, while others, on the contrary, think it is a minor disease like hemorrhoids and do not pay attention to examination and treatment. The correct attitude should be to seek medical attention in time to find out the cause of bleeding, early detection and early treatment.
