Can you have intercourse during an anal fissure?

During an anal fissure, it is possible to have sexual intercourse without any impact on the fissure itself. For patients with an anal fissure, the main focus should be on maintaining smooth bowel movements and avoiding dry and hard stools to prevent irritating the wound, which can cause pain and bleeding. It is also important to avoid diarrhea, as frequent bowel movements can irritate the wound over time and worsen the fissure. Clinically, for early-stage anal fissures, conservative treatment with medications is often recommended, along with softening the stool. Commonly used medications include Dragon Balm ointment or nitroglycerin ointment. After defecation, patients can opt to use an anal wash or a potassium permanganate solution for sitz baths. However, for chronic anal fissures, it is generally advised to undergo fissure excision surgery as soon as possible, followed by regular dressing changes to promote healing of the wound. If an anal fissure is left untreated for a long time, it can lead to slight narrowing of the anal canal, which requires significant attention.

How to improve anal fissure bleeding?

To improve anal fissure and bleeding, the first step is to treat constipation by softening the stool, as most anal fissures are caused by dry stools tearing the local skin and mucous membranes of the anus, leading to bleeding from these tears. For those experiencing pain and bleeding due to anal fissures, it is advisable to apply sesame oil around the anus before each bowel movement to prevent irritations from stool aggravating the fissure, which can cause recurrent pain and bleeding. After defecation, hemorrhoid cream can be applied for hemostatic treatment, and medicinal herbal solutions can be used for local compression and hot compresses to promote the growth and healing of the fissure. (Note: Medications should be used under the guidance of a doctor.)

Anal fissures occur in which part?

Anal fissures are an extremely common condition in proctology. They occur in the fragile and narrowest tissue of the anal canal due to the combined effect of various internal and external factors, leading to the opening and cracking of the digestive tract outlet up to the dentate line and the surface of the anal margin. The oval-shaped small ulcers that form from anal fissures usually occur at the anal region, aligning parallel to the longitudinal direction of the anal canal. The condition is often recurrent and difficult to heal. The angle continuation between the anal canal and the rectum means that the posterior wall of the anal canal is under the most pressure during bowel movements. Therefore, the posterior midline is most susceptible to injury and is also the most common site for the occurrence of anal fissures.

What fruits to eat for anal fissures?

With anal fissures, it is important to maintain smooth bowel movements. Consume more fresh fruits and vegetables, such as bananas, kiwis, strawberries, celery, and spinach, as their rough fibers help lubricate the intestines and facilitate bowel movements. Avoid spicy and irritating foods, foods that cause internal heat, especially avoid chili peppers, onions, ginger, and garlic, and do not drink alcohol, as these can exacerbate constipation and worsen symptoms of anal fissures. Additionally, keep the affected area dry and clean to prevent bacterial infection, and wash with warm water. If there is inflammation in the area of the anal fissure, a sitz bath with potassium permanganate can be used.

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.

What should I do if I have bleeding and anal fissures due to excessive internal heat?

If anal fissures with bleeding occur after excessive internal heat, the acute phase can be treated with warm saltwater sitz baths. If the condition is severe, it is still best to visit a local reputable hospital and receive treatment based on a doctor's diagnosis. Regular attention must be paid to the diet, avoiding spicy, irritating, raw, and cold foods, as well as overly greasy or fried foods, to prevent aggravation of the condition. It is advisable to drink more warm water and eat more fresh fruits and vegetables. Paying attention to rest is crucial, especially avoiding staying up late. Regular physical exercise can also help boost the body's resistance.

How to distinguish between anal fissures and hemorrhoids

To distinguish between anal fissures and hemorrhoids, one can first differentiate based on symptoms. Anal fissures primarily cause pain during defecation and minor bleeding, with the pain typically lasting from 20 minutes to half an hour. Patients often have hard stools or constipation. In contrast, hemorrhoids primarily lead to intermittent painless rectal bleeding. The blood is bright red and usually in greater volume, often appearing in a spraying or dripping pattern after defecation. Some patients may also experience prolapsed hemorrhoids, often accompanied by a sensation of heaviness and foreign body in the anus. Further, through a digital rectal examination, an anal fissure can be identified by a palpable ulcer or crack at the posterior or anterior midline of the anus. Hemorrhoids, being soft venous clusters, can also be differentiated through this examination.

The differences between stages one, two, and three of anal fissures.

In clinical practice, anal fissures are not categorized into stages one, two, or three; they are primarily classified as either acute or chronic anal fissures. Acute anal fissures, which occur in the early stages of the condition, are characterized by pain during defecation and minor bleeding. For such cases, the pain usually doesn’t last long, and conservative treatment with medication can be chosen. Topical applications such as dragon's pearl ointment or nitroglycerin ointment are generally used. It is also important to keep the anal region dry and clean, perhaps by using anal washes for sitz baths, while ensuring that the stool is soft to maintain smooth bowel movements. Chronic anal fissures, on the other hand, are mainly due to the development of scars on the ulcer surface. This condition involves prolonged pain and may include some narrowing of the anus. In such cases, surgical excision of the fissure may be necessary. Post-surgery treatment may include changing dressings with medications like red oil gauze strips, golden ointment, and anal washes. (Under the guidance of a doctor for medication use)

How many days can an anal fissure heal?

Mild anal fissures or those with shallow cracks can generally heal within about a week through local heat application or by applying hemorrhoid cream. However, there is another type of anal fissure known as chronic anal fissure. Chronic anal fissures primarily involve ulcer-like infectious changes at the local site, hence, they cannot heal on their own and can only be alleviated by lubricating the stools and applying hemorrhoid cream locally. In some cases, conservative treatment might not be significantly effective for chronic anal fissures. If surgery is performed, the recovery time is approximately 20 days. It is recommended that patients with chronic anal fissures undergo surgical treatment with endoscopic loosening.

Are anal fissures and hemorrhoids the same thing?

Hemorrhoids and anal fissures are common clinical conditions, but their symptoms are completely different. Generally, they both share a common symptom, which is the presence of rectal bleeding, and this bleeding is usually bright red blood. The difference between anal fissures and hemorrhoids is that anal fissures primarily cause pain, while hemorrhoids primarily cause bleeding. Hemorrhoids only cause severe pain when external hemorrhoids become inflamed and swollen, while anal fissures often involve enlargement of the anal papillae. Hemorrhoids do not involve enlargement of the anal papillae, and while anal fissures can involve skin tears around the anal canal, hemorrhoids do not. During a digital rectal exam, this can be diagnosed; hemorrhoids are caused by poor local venous circulation, leading to venous congestion and the formation of vascular bulges. Depending on their location, they are divided into internal and external hemorrhoids. Anal fissures are skin tears located on the more lateral parts of the anus, and during defecation, the tear worsens, bleeding and causing severe pain, whereas hemorrhoids usually do not cause severe pain.
