The saying that nine out of ten people have hemorrhoids indicates that many people suffer from this type of condition. If you bleed during bowel movements, feel something coming out of your anus, or have a painful swelling outside your anus, you may have hemorrhoids. Early symptoms of hemorrhoids are mainly bleeding during bowel movements, sometimes more bleeding, sometimes dribbling down, and also sometimes bowel bleeding in the form of jets. Over time, it can cause anemia, feeling dizziness, fatigue and so on. Classification: Hemorrhoids include internal hemorrhoids, external hemorrhoids and mixed hemorrhoids, which occur as a result of persistent straining during defecation, resulting in varicose vein plexus at the base of the rectum and anus, as well as downward movement of the anal cushion, which causes repeated elevation of pressure within the veins and the formation of one or more soft venous masses. Internal hemorrhoids are rarely painful, external hemorrhoids are often accompanied by pain and discomfort, and thrombosed external hemorrhoids are associated with severe pain and require emergency treatment. Hemorrhoids are divided into four degrees according to the degree of the disease: first degree hemorrhoids in the anus, bleeding during defecation; second degree hemorrhoids will come out of the anus with defecation, but after defecation that is automatically retracted back into the anus. The third degree, hemorrhoids can not automatically shrink back, you must use your hands to push the hemorrhoids back into the anus. Fourth-degree hemorrhoids have been out of the anus, can not be returned to the anus. Identification: Blood in the stool is the main manifestation of hemorrhoids, but blood in the stool is not always caused by hemorrhoids, this is very important. This is very important. There are many diseases that can cause blood in stool, especially colorectal cancer can also cause blood in stool, especially rectal cancer is very close to the anus, which is very easy to be confused with hemorrhoids. Therefore, once you find blood in the stool, please go to the hospital to see anorectal surgeon immediately, do not easily think that it is simply hemorrhoids, so as not to delay the important condition. Treatment: hemorrhoids treatment methods are many, commonly used: 1, rubber band ligation method: the special rubber band set in the root of the hemorrhoids, so that its natural necrosis, atrophy and fall off, the rubber band is also discharged with the feces. The method is simple, the pain is light, the patient does not need to be hospitalized. Applicable to one or two degrees of smaller hemorrhoids. 2, surgical excision: surgical method to remove all internal and external hemorrhoids. The treatment is more thorough and less likely to recur, but the pain after the operation is slightly obvious, and usually requires hospitalization. At present, hemorrhoid surgical excision treatment effect is better method of ultrasonic scalpel excision and PPH surgery. Ultrasonic knife treatment is less traumatic, hemostatic effect is good, fewer complications, postoperative recovery, applicable to all types of hemorrhoids. PPH method of treatment of hemorrhoids through the principle of lifting the anal cushion, mainly used for the third and fourth degree of heavier hemorrhoids. Prevention: the incidence of hemorrhoids is very high, the prevention of hemorrhoids is of great significance, mainly in the following aspects: 1, prevention of constipation: constipation hard, not only difficult to defecate, and due to the accumulation of fecal matter in the intestinal cavity, defecation force breath holding, so that the anorectal blood vessels within the pressure increases, blood reflux obstacles, which leads to hemorrhoidal venous plexus varicosities and anal cushion downward shift to form hemorrhoids. In order to prevent constipation, should pay attention to the following points: (1) rational allocation of diet: diet with a reasonable not only can increase appetite, improve gastrointestinal function, but also can develop the habit of regular defecation. Daily diet can be more vegetables, fruits, beans and other diet containing vitamins and fiber, less spicy stimulating food, such as chili peppers. (2) Develop healthy bowel habits: It is best to develop the habit of having regular bowel movements every day. Rectal feces accumulated to a certain amount, will produce the desire to go, when there is a desire to go, do not hold back not to go to defecate, a long time in the feces in the water is absorbed, resulting in feces become hard, causing constipation. Squatting too long when defecating, or reading newspapers will increase the pressure in the rectum and anal canal, these are bad defecation habits. (3) using the right way to treat constipation: for general constipation patients, can be used to reasonably allocate the diet, to develop the habit of regular bowel movements to correct. For persistent constipation or constipation caused by certain diseases, should go to the hospital as soon as possible, not long-term laxatives or enemas. Long-term use of laxatives can lead to gastrointestinal dysfunction. Long-term enema will make the rectal mucosa feel sluggish, defecation reflexes, aggravate constipation, easy to lead to the occurrence of hemorrhoids. 2, avoid sedentary, timely treatment of heart, lung, liver and other systemic diseases, so as not to cause increased abdominal pressure and hemorrhoidal venous hypertension, resulting in the occurrence of hemorrhoids. 3, strengthen exercise: often participate in a variety of physical activities such as radio exercises, tai chi, etc., because physical exercise is beneficial to blood circulation, promote gastrointestinal peristalsis, improve pelvic congestion, prevent constipation, prevent hemorrhoids.
