Hemorrhoids are a relatively common disease in surgical clinics, characterized by varicose veins. They generally occur when there is increased abdominal pressure or constipation, which can easily lead to hemorrhoids. Bleeding during defecation is the most common symptom of hemorrhoids. Not all hemorrhoids involve bleeding; it is most common in internal and mixed hemorrhoids. Minor bleeding may not require treatment, but significant bleeding may necessitate the use of topical ointments and oral hemostatics. Additionally, it is important to maintain a light diet, avoid spicy and irritating foods, drink plenty of water, consume fresh vegetables and fruits, and avoid prolonged sitting or standing.

How to alleviate hemorrhoidal bleeding

For hemorrhoid bleeding, it is first necessary to determine the degree of bleeding. If it is mild hemorrhoid bleeding, it can generally be managed with the use of hemorrhoid suppositories to compress and stop the bleeding. If the bleeding is more severe, oral hemostatic medications can be taken. If relief is still not achieved, it is recommended to seek treatment at the hospital's colorectal surgery or gastroenterological surgery departments. If hemorrhoid-induced bleeding occurs frequently and with a large amount each time, it is advisable to consider hemorrhoid surgery as soon as possible. Hemorrhoid bleeding is caused by the tortuous dilation of the inferior rectal venous plexus, which can be injured and cause bleeding either in cases of hard stools or when hemorrhoid symptoms are severe. In the operating room, the diseased vessels need to be removed to fundamentally resolve the cause of the bleeding.

What's causing hemorrhoids to itch?

Hemorrhoids cause secretions to flow out from within the anal canal, particularly in the case of internal hemorrhoids. When severe, these secretions can flow outside the anus due to changes in the position of the anus or the patient's body, irritating the local skin and mucosa around the anus, thus leading to symptoms of itching. Additionally, with repeated prolapse of internal hemorrhoids, the mucosa may get trapped at the anal opening and cannot retract normally, also causing irritating itching and possibly even pain and bleeding due to repeated friction. To treat the itching from hemorrhoids, it is first necessary to alleviate the increased secretion from internal hemorrhoids. Options include using anti-inflammatory suppositories or gels, and washing the anal area with saline water or herbal washes that have antipruritic effects.

Do hemorrhoids require surgery?

When severe hemorrhoids are in an acute attack phase, it is necessary to undergo surgical treatment as soon as possible. Besides surgery, treatment options for hemorrhoids also include conservative medication to alleviate symptoms. For mild hemorrhoids, or those that flare up less frequently, the primary treatment is conservative topical medication. However, when hemorrhoids repeatedly prolapse, cause pain, and result in significant rectal bleeding, affecting the normal functioning of the patient’s body, it is advised to promptly proceed with hemorrhoidectomy surgery. This helps avoid complications such as severe pain that interferes with normal living, or significant bleeding that could lead to anemia in patients, thereby worsening the condition and increasing the difficulty of future treatments. (Please use medication under the guidance of a professional physician, and do not self-medicate.)

How come hemorrhoids bleed?

In this case, it depends on the cause of the hemorrhoids. In general, the most common cause of hemorrhoids is varicose veins around the rectal veins, which can be caused by obstructed venous return. Generally, there are no corresponding venous valves around the upper rectal veins, and the veins or small vein walls of hemorrhoids are very thin. In the case of hemorrhoidal venous varicose, if the stool is relatively dry, it is easy to cause the veins to rupture and bleed during defecation. This type of bleeding is generally painless, and the bleeding can stop on its own, usually being bright red blood. Due to high local pressure, some people may experience significant bleeding, or even show signs of shock. In this case, surgical treatment measures must be taken to achieve radical cure.
