What should I pay attention to for anal fissures? Friends who suffer from anal fissures should note the following: Firstly, pay attention to your diet. Adjust your diet structurally to be diverse. Drink plenty of water and eat less spicy and stimulating food; abstain from alcohol and betel nuts; eat less spicy hot pot and similar foods. Also, maintain a smooth bowel movement. We should develop a habit of defecating regularly, and treat constipation correctly. However, in treating constipation, we should not misuse laxatives and should use medications under the proper guidance of a doctor. We should also pay attention to keeping the anal area clean and hygienic by washing it after each bowel movement. After defecation, it is best to perform sitz baths using salt water, traditional Chinese medicine pain relievers like Shen Tang, or potassium permanganate solution. This helps in the recovery of the anal fissure. In addition to the above, we should also engage in appropriate activities. Friends with anal fissures can perform anal muscle contractions, such as Kegel exercises or stretching exercises.

What foods should be avoided with anal fissures?

People with anal fissures should avoid consuming chili peppers and alcohol. Chili peppers contain a compound called capsaicin, which can strongly irritate the nerves in the gastrointestinal tract and the ulcers of anal fissures, causing severe pain in the affected area. Additionally, capsaicin can dilate the mucosal blood vessels, leading to bleeding in the anal fissures. Alcohol has a similar effect, as it can exacerbate congestion and blood stasis in the anal and rectal areas. In most cases, consuming chili peppers and alcohol can intensify the pain.

How to treat hemorrhoids, bloody stool, and anal fissures?

Hemorrhoids and anal fissures are two different conditions. Generally, the early treatment for anal fissures is similar to that for early hemorrhoids, which is conservative treatment. This includes ensuring smooth bowel movements, preventing constipation, avoiding dry stools, preventing prolonged bowel movements, and avoiding sitting still for long periods. If the amount of bleeding is small, conservative treatment as mentioned above, along with the application of local medication around the anus, can control the symptoms. Regularly consume vegetables and dietary fiber. If there is severe bleeding from hemorrhoids or severe pain due to a large fissure in anal fissures, relevant examinations should be conducted. After ruling out other conditions, surgery may be necessary.

Can diarrhea cause anal fissures?

Diarrhea may cause anal fissures. An anal fissure refers to a full-thickness vertical tear in the skin of the anal canal below the dentate line, forming an ischemic ulcer. It is commonly found in young and middle-aged adults, and the exact mechanism of its development is not very clear. It is mainly related to local muscle spasms and infection following injury. The main symptoms include severe, sharp pain during and after bowel movements, along with occasional light, bright red bleeding. There may also be constipation and anal discharge. If the skin of the anal canal is chronically irritated by prolonged diarrhea, causing skin damage, it is very likely to lead to an anal fissure.

What is the best treatment for anal fissures?

How should an anal fissure be treated? It can be addressed from several aspects. First, let's talk about general treatment. What is the principle of our treatment? It is to relieve pain after bowel movements and gradually promote the healing of the fissure. However, the first step is to relieve the spasm of the sphincter, then facilitate bowel movements to interrupt the vicious cycle. But what specific measures are there? One is to take a sitz bath with traditional Chinese medicine for pain relief, such as "Shen Soup," and a 1:5000 potassium permanganate solution after defecation, maintaining local cleanliness. Then, by orally taking some laxatives or paraffin oil, feces can be softened and lubricated. Alternatively, by increasing water intake and eating more fiber-rich foods, constipation can be corrected to keep the bowels clear. In more severe cases, such as those with sphincter spasms, we can perform anal dilation under local anesthesia. By dilating the anus, the spasm of the sphincter can be relieved, and the healing of the fissure can also be promoted. However, this method has a relatively high recurrence rate, and there may also be complications such as severe bleeding, perianal abscess, and fecal incontinence. Anal dilation should be treated by a doctor, and patients should not blindly use it themselves. Of course, there is also surgical treatment. Once an anal fissure has reached a certain degree, generally a chronic anal fissure, many patients need to undergo surgical treatment. Naturally, there are several surgical methods available. We choose different surgical methods according to the condition and severity of the anal fissure. For example, if the patient has an anal fissure that presents with sentinel piles and hypertrophic anal papillae, but there is no anal stricture or internal sphincter spasm, a simple excision of the fissure can be performed. This involves removing the pathological tissue of the fissure, excising the infective anal sinus along with the hypertrophic anal papillae and sentinel piles, allowing the fissure wound to drain openly. However, if there is associated anal stricture, or there is an internal sphincter spasm, we also need to perform an internal sphincterotomy.

What should I do about anal bleeding and anal fissures?

If a fissure is visible to the naked eye at the anal sphincter during a digital rectal examination, it is primarily considered an anal fissure. Anal fissures generally cause severe local pain and bleeding from the fissure. The fissure is primarily due to the local crack being stretched or opened, causing bleeding from small blood vessels, and the blood from the fissure is usually bright red. To treat bleeding from an anal fissure, it is first necessary to soften the stool, as the occurrence of an anal fissure is mainly related to dry stools and difficulty defecating. Once the stool is lubricated, it can reduce the need to exert excessive force during defecation, lowering the possibility of stretching the local fissure. Topical application of hemorrhoid cream at the fissure, or combined with oral medications that cool the blood and stop bleeding, may be used. If there is repeated bleeding from an anal fissure, surgical treatment is also recommended. (Please use medications under the guidance of a professional physician, and do not self-medicate.)
