First, the definition of hemorrhoids Hemorrhoids is the human rectum end of the submucosa and the skin of the anal canal under the venous plexus dilatation and flexion of the soft venous mass, hemorrhoids are also known as hemorrhoids, hemorrhoidal nuclei, hemorrhoidal disease, hemorrhoidal disease and so on. Medical hemorrhoids, including internal hemorrhoids, external hemorrhoids and mixed hemorrhoids, is the bottom of the anorectum and the anal mucosa of the venous plexus varicose and formed one or more soft venous masses of a chronic disease. Second, the classification of hemorrhoids internal hemorrhoids: internal hemorrhoids surface covered by mucous membrane, located above the tooth line. The consequences of internal hemorrhoids are generally more serious, and therefore require timely treatment. If the internal hemorrhoids are not treated, then the patient may be made to endure severe pain for a long time. The most common symptoms of internal hemorrhoids are blood in the stool, anal itching, and in severe cases, the internal hemorrhoids may prolapse out of the anus. External hemorrhoids: External hemorrhoids occur on the surface skin of the anal area, located below the dentate line, and can be easily touched, and their symptoms usually manifest as pain and swelling. Acute thrombosed external hemorrhoids are more painful. The common types are connective tissue external hemorrhoids, varicose external hemorrhoids, inflammatory external hemorrhoids and thrombosed external hemorrhoids. Mixed hemorrhoids: Mixed hemorrhoids occur in the anus in the same position above and below the dentate line, varicose veins form a mass, internal and external connected, no obvious demarcation as the main manifestation of hemorrhoidal disease. Is occurring near the dentate line, to the skin and mucous membrane junction tissue coverage, the formation of internal hemorrhoids and external hemorrhoids two characteristics of hemorrhoidal veins. Third, the typical symptoms of hemorrhoids 1, bleeding in the stool: painless, intermittent after stool with bright red blood is its characteristics, but also the internal hemorrhoids or mixed hemorrhoids early common symptoms. Bleeding usually occurs before or after defecation, there is simple blood in the stool, will also be mixed with the stool and down. The color of blood is bright red, and the bleeding is in the form of jet, dripping, wiping with blood and so on. 2.Pain in stool: there is bleeding and perianal pain during stool. Because the perianal nervous system is more developed and sensitive, it is easy to have pain after being stimulated. Generally manifested as mild pain, stabbing pain, burning pain, distension and so on. 3, rectal pain: anorectal pain is mainly a symptom of internal hemorrhoids. If the internal hemorrhoids are infected, embedded, and strangulation necrosis occurs, it will lead to severe pain. In the light case, there is a feeling of swelling and falling, and in the heavy case, there will be heavy falling pain. 4, the swelling out: the anal internal swelling out, this is mainly in the late stage of internal hemorrhoids symptoms. As the internal hemorrhoidal hemorrhoidal nuclei continue to grow, so that the mucous membrane and submucous membrane layer and the anal layer separation, defecation, internal hemorrhoidal nodules can be down to the dentate line below, free from the anal canal outside the anal canal, through the anus out. In light cases, the hemorrhoids will only come out of the anus when defecating, and in heavy cases, they can come out of the anus when coughing, pressing on the abdomen, or squatting with force. 5, anal discharge secretion: anal discharge secretion, mainly by the fistula overflow, will also be discharged from the anus, or by the perianal skin overflow. The rectal mucosa is stimulated by hemorrhoids for a long time, causing increased secretions. In advanced internal hemorrhoids, due to the relaxation of the anal sphincter, secretions often flow out of the anus. Light outflow during bowel movement, heavy outflow when not defecating. 6, anal itching: anal and perianal skin itching symptoms. It is mainly due to the anal secretions, prolapsed hemorrhoidal nuclei and the surrounding skin is stimulated, the skin is wet all day long, which produces a sense of itching, leading to the occurrence of anal eczema and itching. Fourth, the clinical manifestations of various types of hemorrhoids Hemorrhoids are usually divided into internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, according to the severity of the condition and staging. The common symptoms of internal hemorrhoids are bleeding, prolapse, swelling, pain, divided into 4 degrees: I degree: blood with stool, dripping blood, bleeding can stop by itself after stool; no hemorrhoidal prolapse. Degree II: blood in the stool; hemorrhoids prolapse during defecation, which can be self-contained after defecation. Degree III: blood in stool; hemorrhoids prolapse during defecation or prolonged standing, coughing, exertion and weight-bearing, and need to be restored by hand. IV degree: there may be blood in the stool; hemorrhoids continue to prolapse or prolapse easily after restoration. External hemorrhoids usually have no special symptoms, thrombosis and inflammation can have swelling, pain. Mixed hemorrhoids are mainly manifested as symptoms of internal and external hemorrhoids at the same time. Fifth, hemorrhoids harm: 1, anal dysfunction: prolonged illness, on the one hand, leading to anal contracture, defecation difficulties; on the other hand, invasion of the sphincter, easy to lead to anal incontinence. 2, lead to sepsis, toxemia, septicemia: anal abscess, anal infection once formed, produce bleeding symptoms, bacteria, toxins, pus plugs will be easy to invade the blood triggering sepsis, toxemia, thick toxemia. 3, cause gynecological diseases: due to the anus and vagina close, hemorrhoidal bleeding or inflammation will often lead to a large number of bacterial reproduction, triggering gynecological inflammation. 4, easy to cause plant nervous disorders: can cause lumbar, epiphyseal, post-femoral areas of pain, but also can cause reflex dysfunction of the genitourinary system. 5, skin eczema: due to hemorrhoidal mass prolapse led to sphincter relaxation, mucus outflow outside the anus to stimulate the surrounding skin, easy to cause itching and skin eczema. 6, cover up the late rectum: relevant data show that the misdiagnosis rate of the late rectum in China is between 70% and 88.57%. Hemorrhoids and advanced rectal most prominent similar symptoms is blood in the stool, many people take the bleeding of the late intestinal bleeding as hemorrhoids, resulting in a delay in the treatment of the time, wait until you go to see a doctor often has been in the late stage. In fact, under the existing medical conditions, many malignant tumors occurring in the colon or rectum, if early diagnosis, early treatment, the chance of cure is still relatively large. Treatment of hemorrhoids must choose regular professional hospitals, blindly taking drugs or blind treatment will only lead to the deterioration of the condition, patients must be cautious.
