Anal fissure

Constipation

This condition involves having large, hard, dry stools that are difficult or painful to pass. Constipation increases the likelihood of lesions forming in the anal region during bowel movements.

Chronic Diarrhea

Prolonged diarrhea can lead to skin dryness and cracking around the anus. Since the skin in this area is highly sensitive, constant diarrhea may cause an anal fissure, resulting in significant pain.

Pregnancy and Childbirth

Pregnant women are more likely to develop anal fissures as the pregnancy progresses. Additionally, the tissues around the anus may tear during childbirth, contributing to the development of fissures.

Muscle Spasms

Spasms in the anal muscles can tear the inner lining of the anus during bowel movements, potentially leading to chronic anal fissures.

Anal Intercourse

Any trauma to the anal tissues, including rough anal intercourse or the insertion of objects into the anus, can overstretch the skin, causing an anal fissure.

HIV

For HIV-positive individuals, anal lesions associated with HIV can lead to debilitating pain during defecation. These lesions may be more severe and cause pain unrelated to bowel movements.

Tuberculosis

Anal tuberculosis can result in persistent, recurrent ulcer-like fissures in the anal region that do not heal.

Other Conditions

Several other conditions may contribute to anal fissures, including:

• Crohn's Disease: An inflammatory bowel disease that causes inflammation in the digestive tract.
• Ulcerative Colitis: An inflammatory bowel disease that leads to inflammation and ulcers in the digestive tract.
• STDs: Sexually transmitted diseases such as syphilis, gonorrhea, chlamydia, and chancroid.
• Minor Trauma: Injuries to the anal region caused by activities like mountain biking, or the insertion of a rectal thermometer, enema tip, or ultrasound probe.
• Weight Loss Surgery: This procedure can result in explosive diarrhea, which may contribute to anal fissures.

While minor anal fissures may heal independently and cause minimal discomfort, chronic fissures often require medical attention. Proper diagnosis helps determine the best treatment approach. The diagnostic process includes the following steps:

Medical History

• The doctor will ask detailed questions about the patient’s symptoms, dietary habits, bowel habits, and any medications currently or previously used for health conditions.

Physical Examination

• A visual inspection of the anal area is performed by gently separating the buttocks. If a fissure is not visible, a more thorough rectal examination may be needed, typically after applying a topical anesthetic to the anus and anal canal. A cotton-tipped swab may be used gently inside the anus to pinpoint the source of pain.

Colonoscopy or Sigmoidoscopy

• If rectal bleeding is present, an endoscopic exam may be necessary to rule out more serious conditions such as colon cancer or solitary rectal ulcer syndrome, which can cause rectal bleeding and discomfort during bowel movements. A small, flexible tube is inserted into the anus to inspect the entire colon.

To help prevent anal fissures, consider the following preventive steps:

Consume a Fiber-Rich Diet

• Fiber improves stool consistency and adds bulk to bowel movements, reducing the chances of constipation and, consequently, anal fissures. Foods like fruits, vegetables, legumes, nuts, and whole grains are excellent sources of fiber. Adults should aim for at least 18 grams of fiber per day.

Stay Hydrated

• Drinking enough water is essential for smooth bowel movements. Aim to drink at least 8 glasses of water daily, as it can make stools easier to pass and reduce the risk of anal fissures. Try to limit alcoholic and caffeinated beverages, as they can lead to dehydration.

Avoid Delaying Bowel Movements

• Delaying the urge to pass stools can strain your anal muscles and lead to harder, drier stools. This increases the risk of constipation and anal fissures.

Be Cautious with Laxatives

• Only use laxatives when prescribed by your doctor. They should be used for short-term relief of occasional constipation and not as a long-term solution.

Stay Active

• Regular physical activity helps boost your metabolism and prevent constipation. Aim for 10,000 steps daily to maintain good digestive health.

Specialists to Visit

Doctors who can assist in diagnosing and treating anal fissures include:

• General Physician
• Gastroenterologists
• Proctologists
• Pediatrician (for children)

A gastroenterologist specializes in treating disorders of the gastrointestinal system, while a proctologist focuses on conditions related to the colon, rectum, and anus.

When to See a Doctor?

While many anal fissures heal on their own, consult a doctor if you experience:

• Chronic constipation
• Severe pain during bowel movements
• Presence of blood in the stool

The treatment for anal fissures typically involves medications and dietary modifications to soften stools or aid in their movement through the colon.

Medications

• Topical Anesthetic Ointments: Patients often find relief by applying topical anesthetics such as lidocaine hydrochloride creams to the affected area. These can be either over-the-counter or prescribed by a doctor.
• Nitroglycerin: When applied to the affected area, nitroglycerin ointment increases blood flow to the damaged tissue. This promotes healing and helps to alleviate muscle spasms in the anal sphincter.
• Calcium Channel Blockers (CCBs): Medications like nifedipine or diltiazem are used to reduce blood pressure and relieve spasms in the anal sphincter. They can be taken orally or applied directly to the area.
• Botox Injections: If other treatments are ineffective, Botox injections may be used to treat persistent anal fissures. Botox works by paralyzing the anal sphincter muscles, which helps relieve spasms.

Surgery

If an anal fissure does not respond to medical treatments, your doctor may recommend surgery. One common procedure is lateral internal sphincterotomy (LIS), which involves making a small incision in the anal sphincter muscle to reduce spasms and promote healing.

Complications that may arise from an anal fissure include:

Failure to Heal: Typically, an anal fissure should heal within six weeks, but in some cases, it may persist beyond eight weeks, becoming chronic. In such situations, surgery may be necessary to treat the condition effectively.

Relapse: After experiencing an anal fissure, the likelihood of developing another one or having a recurrence is higher.

Anal Fistula: If an anal fissure remains untreated or does not heal properly, it can lead to infection, which may result in the formation of an anal fistula. This is an infected tunnel connecting the skin and the anus, causing intense pain, swelling, and discharge of pus or blood from the anal area.

Anal fissures can cause significant pain and discomfort, impacting daily life. Alternative therapies can be used alongside conventional treatments to alleviate symptoms.

Yoga

Yoga can help manage symptoms, ease bowel movements, and reduce constipation. Some useful yoga poses include:

• Viparita Karani (legs-up-the-wall pose)
• Trikonasana (triangle pose)
• Dhanurasana (bow pose)
• Matsyasana (fish pose)
• Anjaneyasana (crescent lunge pose)
• Pavanamuktasana (wind-relieving pose)
• Balasana (child’s pose)

The following home remedies can help alleviate constipation, promote healing, and prevent worsening of anal fissures. Along with staying hydrated and maintaining physical activity, these tips may offer additional relief:

Manage Constipation

Since constipation is a primary cause of anal fissures, managing it is crucial to both prevent and facilitate the healing of fissures. Ensuring regular, soft bowel movements is essential for recovery.

Try a Sitz Bath

A sitz bath, also known as a hip bath, involves soaking the hips in warm water. This can help soothe the area and promote healing. You can take a sitz bath for 20 minutes at least twice a day, either using a sitz bath kit or simply in your bathtub.

Keep the Anal Area Lubricated

To help make bowel movements easier and reduce discomfort, it is important to keep the anal area moisturized and lubricated. Always consult your doctor before using any of these remedies:

• Petroleum Jelly: Applying petroleum jelly around the anal region helps lubricate the skin, making it easier to pass stools without strain or bleeding.

• Aloe Vera: Aloe vera is known for its healing and pain-relieving properties. Applying natural aloe vera gel to the affected area can help manage chronic fissures effectively.

• Coconut Oil: Coconut oil has excellent healing qualities and acts as a natural lubricant. Applying it twice a day around the anal region can aid in healing anal fissures.

• Olive Oil: Olive oil is rich in monounsaturated fats and serves as a lubricating agent, making it easier to pass hard stools. It also has anti-inflammatory properties that help reduce pain caused by anal fissures. A natural mixture of olive oil, honey, and beeswax has been shown to reduce pain, bleeding, and itching in some patients.

• Castor Oil: Castor oil is not only an effective natural laxative when taken with milk but can also be applied directly to the anal area to help alleviate pain and facilitate smoother bowel movements.

Anal fissures are quite common and often heal on their own with proper care. However, in some cases, medical treatment or surgery may be necessary. Here are a few tips to help manage anal fissures in daily life:

• Taking regular warm sitz baths can reduce pain and discomfort. Ensure your bathtub is clean after each use, and always use clean, dry towels to avoid infection.
• Avoid using scented soaps or shower gels, as they can irritate the area. Instead, opt for mild, fragrance-free soaps designed for sensitive skin.
• Prolonged sitting on the toilet seat increases pressure on the lower rectum and anus, which can hinder healing. Straining during bowel movements may also lead to additional tears.
• Gently clean the anal area after bowel movements to avoid irritation or infection.
• Avoid consuming refined or processed foods, as they can worsen symptoms.
• Stay hydrated and incorporate fiber-rich foods into your diet to prevent constipation.
• Certain medications, like iron supplements or antacids, can cause constipation, which may trigger anal fissures. Inform your doctor if you notice any changes after starting a new medication, as they may recommend alternatives that do not contribute to constipation.
