The soft venous mass formed by the dilatation and flexion of the venous plexus under the mucous membrane at the end of the human rectum and the skin of the anal canal is called hemorrhoid, also known as hemorrhoid, hemorrhoid, hemorrhoid disease, hemorrhoid disease, etc. In Chinese medicine, the meaning of hemorrhoids has been discussed more, such as in “Shuowen Jiezi”, which says: “After the disease also.” In “Zeng Yun”, it says: “Hidden sore also.” In terms of word meaning, hemorrhoid is synonymous with standoff, which means high protrusion. For example, the Medical Compendium says: “The intestines of the intestines of the body are not only the same, but also the same as the nine orifices of the body, where small flesh is protruding.

Hemorrhoids are a common and frequent disease that is unique to humans. According to the census data, the incidence of anorectal diseases is 59.1%, and hemorrhoids account for 87.25% of all anorectal diseases, of which internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases. The incidence of hemorrhoids is 67% for women and 53.9% for men; they can develop at any age, and are more common in people aged 20-40, and gradually worsen with age, so there are “nine hemorrhoids in ten people”. The former is named after the clinical feature of bleeding, while the latter is named after the outer shape of hemorrhoids, which resembles a ball and refers to both internal and external hemorrhoids. The first is named after the clinical feature of bleeding, and the second is named from the outer shape of the hemorrhoid, which resembles a ball, and refers to both internal and external hemorrhoids. Usually when straining continuously during defecation causes a repeated increase in pressure in the veins here, the veins become enlarged. Hemorrhoids often occur in women during pregnancy due to compression of the pelvic veins, which hinders blood circulation, and many obese people also suffer from hemorrhoids. If you have hemorrhoids, the walls of the enlarged and twisted veins in the anus become very thin, so they can easily rupture during defecation. Internal hemorrhoids are those that grow at the beginning of the anal canal. If the swollen vein is located further down, almost over the opening of the anal canal, this varicose vein is called an external hemorrhoid. External hemorrhoids can sometimes protrude or protrude outside the opening of the anal canal. However, this only happens during defecation and it retracts back to its original position after defecation. Blood clots can occur in both internal and external hemorrhoids. In the event of a blood clot, the blood in the hemorrhoid clots together, causing pain. Internal hemorrhoids have the following characteristics: i. they are located above the dentate line of the anus; ii. they are formed by the dilated and flexed suprarectal venous plexus; iii. the surface of the hemorrhoid nucleus is covered by the rectal anal canal mucosa. The symptoms of internal hemorrhoids are mainly bleeding, which is often difficult to detect in patients with early internal hemorrhoids without bleeding. The amount of bleeding varies, and bright red blood spurting out of the anus is one of its distinctive features. Each bleeding is associated with a bowel movement and occurs during or at the end of a bowel movement. If the hemorrhoid grows further, it may prolapse out of the anus during defecation. Some of them may disappear by themselves at the end of defecation, while others may require finger rest or bed rest for a period of time before they slowly return. If the above treatment still does not allow it to enter the anus, the hemorrhoid can get stuck at the anal opening and become embedded and strangulated, which is a common complication of internal hemorrhoids. External hemorrhoids have the following characteristics: i. They are located below the dentate line of the anus; ii. They are formed by the expansion and flexion of the inferior rectal plexus; iii. The surface of the hemorrhoid is covered by the anal skin. The main symptom of external hemorrhoids is the protrusion of the skin at the anal verge. Asymptomatic external hemorrhoids: this skin flap is soft and flexible and can be painless or otherwise uncomfortable for a long time, except for some difficulties that may be caused by anal cleanliness and hygiene. Most patients only find them accidentally when bathing or defecating. In this case, external hemorrhoids are also known as “varicose external hemorrhoids”, which are irregular clusters of veins at the anal opening. (1) The skin of the external hemorrhoid is damaged or infected, resulting in inflammatory manifestations such as redness, swelling and pain, called “inflammatory external hemorrhoids”; (2) Under the stimulation of long-term chronic inflammation, the skin of the external hemorrhoid becomes fibrotic, hyperplastic and hardened, and produces discomfort such as anal dampness and itching, called “connective tissue external hemorrhoids”. “(c) The rupture of blood vessels at the anal verge during defecation, hard labor, coughing, sneezing, etc., causes blood to collect under the skin to form a mass and cause pain, which is called “thrombosed external hemorrhoid”. The common symptoms of hemorrhoids are: a. Bleeding: Painless anal bleeding is the most common symptom of hemorrhoids. It usually appears in the early stages of the disease and is the main reason for patients to visit the clinic. The bleeding is bright red and initially manifests itself as blood on the straw paper when relieving hard stools. As the disease progresses, blood will drip or squirt from the anus at the end of a bowel movement, and the bleeding will stain the toilet in large amounts. This type of bleeding is one of the characteristics of hemorrhoids. In the later stages of the disease, there can also be a persistent bloody mucus discharge unrelated to defecation, mostly in older patients. Second, hemorrhoid prolapse: prolapse is a manifestation of further enlargement of the hemorrhoid, mostly in conjunction with anal bleeding. In some patients, there is only prolapse without bleeding. The soft hemorrhoid prolapses from the anal opening when you hold your breath and force a bowel movement, and can retract back to the anus on its own after defecation. Sometimes it needs to be pushed into the anus with the finger. This is also a characteristic manifestation of hemorrhoids. In severe cases, the hemorrhoid can also prolapse when you are not defecating and your finger cannot return it, or it can prolapse and get stuck at the anal opening, causing swelling and pain, a condition that requires immediate attention. Third, anal pain and discomfort: uncomplicated hemorrhoids generally do not present significant pain, only the discomfort of swelling at the anal opening or a slight dull pain in the anus after a bowel movement. Severe anal pain is seen when there is thrombosis within the hemorrhoid. The nature of the pain is constant swelling or dull pain, which is difficult for patients to tolerate and therefore seek medical attention. The anal flap: When you have external hemorrhoids or mixed hemorrhoids, there will be a painless soft flap around the anal opening, one or more, which basically brings no discomfort. If the flap is infected, it may appear swollen and painful, break down, and flow pus. The skin flab will also become hard due to fibrosis in the long run. Five, perianal dermatitis and anal itching: hemorrhoids continue to prolapse outside the anus, due to the stimulation of secretions, perianal skin will appear moist, itchy, painful and even ulcerated. Multiple anal dermatomes can cause inability to wipe the anus after defecation, which can cause perianal dermatitis and itching in the long run. How to prevent the occurrence of hemorrhoids? The main function of the anus is to defecate, so defecation and hemorrhoids are inseparably related. Constipation and diarrhea can both stagnate the veins around the anus and play an important role in the development of hemorrhoids. The key to preventing hemorrhoids is to maintain normal bowel function. This is important for both those who do not suffer from hemorrhoids and those who already do. The main measures to prevent hemorrhoids are: a. Maintain good bowel habits; b. Pay attention to dietary health, balanced nutrition, eat more food rich in dietary fiber; c. Avoid overwork, avoid sitting, standing or maintaining the same posture for a long time, and participate in appropriate physical activities; d. Regularly exercise the contraction of the anal muscles; e. Actively treat various chronic diseases that increase intra-abdominal pressure, such as chronic bronchitis, prostate hypertrophy, cirrhosis of the liver, V. Actively treat chronic diseases that increase intra-abdominal pressure, such as chronic bronchitis, prostate hypertrophy, liver cirrhosis, and tumors in the abdominal cavity and pelvis; VI.
