Anal fissures and hemorrhoids are frequent anorectal issues that vary in their causes and symptoms. Hemorrhoids often result from repeated pressure on the anal and rectal veins, whereas anal fissures typically arise from trauma to the anal canal, often during bowel movements. 

Proper distinction is crucial for prevention and treatment.

What Are Anal Fissures?

An anal fissure is a small tear or crack in the lining of the anus, the opening through which stool passes out of the body. This condition can cause significant discomfort and pain, particularly during and after bowel movements. The anal canal, which connects the rectum to the anus, is lined with sensitive tissue that can easily become damaged.

Anal fissures are common and can affect people of all ages, though they are particularly prevalent among infants and middle-aged adults.

Symptoms

Anal fissures are often identified by their distinct symptoms. Common symptoms include:

  • Bleeding from the rectum: Bright red blood on toilet paper or in the toilet bowl after a bowel movement.
  • Pain during and after bowel movements: Sharp, intense pain that can last for several minutes to hours post-defecation.
  • Discomfort or tenderness in the anal area: Persistent pain and tenderness around the anus, which can be exacerbated by sitting or passing stool.

These symptoms can vary in severity, but even minor fissures can be quite painful due to the sensitive nature of the affected area.

Causes

Anal fissures are typically caused by trauma to the anal canal, which can occur due to various factors:

  • Constipation: Hard, dry stools that are difficult to pass can stretch and tear the anal lining.
  • Diarrhea: Frequent, loose stools can irritate and damage the delicate tissue of the anal canal.
  • Inflammatory bowel disease (IBD): Conditions like Crohn's disease and ulcerative colitis can cause chronic inflammation, increasing the risk of fissures.
  • Trauma: Physical injury or strain, such as during childbirth or from the insertion of foreign objects, can lead to fissures.
  • Anal Intercourse: Engaging in anal intercourse can cause trauma to the anal canal, potentially resulting in fissures.

What Are Hemorrhoids?

Hemorrhoids are swollen and inflamed veins located in the lower rectum and anus. They are similar to varicose veins and can be found either inside the rectum (internal hemorrhoids) or under the skin around the anus (external hemorrhoids).

Hemorrhoids are very common and often go unnoticed until they cause symptoms such as bleeding or discomfort.

Symptoms

The symptoms of hemorrhoids can vary based on whether they are internal or external, but common symptoms include:

  • Rectal bleeding: Bright red blood on toilet paper, in the stool, or in the toilet bowl.
  • Itching or discomfort around the anus: Persistent itching or irritation in the anal region.
  • Pain during bowel movements: Discomfort or sharp pain when passing stool, particularly with external hemorrhoids. 

These symptoms can affect daily activities and quality of life, making it important to identify and treat hemorrhoids promptly.

Causes

Hemorrhoids develop due to increased pressure in the lower rectum, which can be caused by various factors:

  • Constipation: Straining during bowel movements can put extra pressure on the veins in the rectal area.
  • Diarrhea: Frequent bowel movements can irritate and inflame the veins in the anus.
  • Pregnancy: The increased pressure on the pelvic blood vessels during pregnancy can lead to hemorrhoids.
  • Heavy lifting: Repeated heavy lifting or straining can increase abdominal pressure and contribute to the development of hemorrhoids.

Comparison of Anal Fissures and Hemorrhoids

Anal fissures and hemorrhoids, while both affecting the anal region, have distinct differences in their presentation and symptoms. One key difference is pain: hemorrhoids don’t always cause pain, whereas 90% of fissures do.

Here’s a detailed comparison to help distinguish between these two conditions:

Feature Anal Fissures Hemorrhoids
Definition Tear or crack in the anal canal Swollen veins in the rectum or anus
Symptoms Severe pain during/after bowel movements Itching, pain, and bleeding
in or around the anus
Causes Constipation
Diarrhea
Trauma

Diarrhea
Pregnancy
Heavy lifting
Duration Acute or chronic, may require surgery Usually resolves with home treatment,
can recur
Complications Chronic pain, requires surgical intervention Severe pain, thrombosis,

Diagnosis of Anal Fissures and Hemorrhoids

Physical Examination

To diagnose anal fissures or hemorrhoids, a healthcare provider will perform a physical examination, which includes:

  • Visual Inspection: Checking the anal area for signs of fissures or external hemorrhoids.
  • Digital Rectal Exam: Inserting a gloved, lubricated finger into the rectum to feel for internal hemorrhoids or other abnormalities.

Diagnostic Tests

In some cases, additional diagnostic tests are necessary to confirm the diagnosis or to rule out other conditions. These tests may include:

  • Anoscopy: A lighted tube examines the inside of the anal canal.
  • Proctoscopy: A longer tube inspects the rectum and lower colon.
  • Biopsy: A tissue sample may be taken to rule out more serious conditions like cancer.

Treatment Options

Common Treatments

Some treatments can help both anal fissures and hemorrhoids by improving overall anorectal health and reducing symptoms:

  • Sitz Baths: Sitting in warm water for 10-20 minutes several times a day can relieve pain and promote healing.
  • Dietary Changes: Increasing fiber intake through fruits, vegetables, legumes, and whole grains helps soften stools and reduce straining.
  • Increased Water Intake: Drinking plenty of fluids keeps stools soft and prevents constipation.

Treatment for Anal Fissures

Specific treatments for anal fissures focus on healing the tear and reducing pain:

  • Topical Ointments: Medications to relax the anal sphincter and promote blood flow to aid healing.
  • Pain Relief: Over-the-counter pain relievers can help manage discomfort.
  • Surgical Procedures: For chronic fissures, procedures like lateral internal sphincterotomy reduce tension in the anal sphincter, promoting healing. As noted by the Cleveland Clinic, medications for chronic anal fissures have inconsistent results, but surgery, when required, has a 90% success rate.

Treatment for Hemorrhoids

Hemorrhoid treatments aim to reduce swelling and alleviate symptoms:

  • Topical Creams and Ointments: Over-the-counter creams can reduce itching, pain, and swelling.
  • Stool Softeners: These help ease bowel movements and reduce strain on hemorrhoids.
  • Surgical Procedures: In severe cases, treatments like rubber band ligation, sclerotherapy, or hemorrhoidectomy may be necessary to remove or shrink hemorrhoids.

Prevention Tips

Preventing anal fissures and hemorrhoids involves adopting healthy lifestyle habits that promote regular bowel movements and reduce strain on the anal and rectal areas. Here are some practical tips to help prevent these conditions:

Diet and Hydration

A balanced diet rich in fiber and adequate hydration is essential for maintaining digestive health and preventing both anal fissures and hemorrhoids.

  • Increase Fiber Intake: Consuming plenty of fiber helps to soften stools and promote regular bowel movements. Include foods such as fruits, vegetables, whole grains, and legumes in your diet. Aim for at least 25-30 grams of fiber daily.
  • Stay Hydrated: Drinking sufficient water is crucial for softening stools and preventing constipation. Aim for at least 8-10 glasses of water per day, and adjust based on your activity level and climate.

Bathroom Habits

Adopting healthy bathroom habits can significantly reduce the risk of developing anal fissures and hemorrhoids.

  • Avoid Straining: Straining during bowel movements puts excessive pressure on the anal and rectal veins, leading to fissures and hemorrhoids. Dr. Karen Zaghiyan, MD, a colorectal surgeon and Director of the Colorectal Cancer Tumor Board at the Samuel Oschin Comprehensive Cancer Institute, notes: “If a bowel movement is not produced after a couple minutes on the john, don’t force it. Instead, get up and go do something else. When you have the urge to go again, you may return to the toilet.
  • Don’t Delay: Go to the bathroom as soon as you feel the urge. Delaying bowel movements can lead to harder stools and increased strain.
  • Limit Toilet Time: Avoid sitting on the toilet for extended periods, as this can increase pressure on the rectal veins. If you enjoy reading, do so outside the bathroom. 
  • Avoid Phone Usage: To minimize the time spent on the toilet, avoid using your phone or other devices while in the bathroom. Dr. Zaghiyan explains: “It’s not the actual act of using a smartphone that is the problem. Rather, sitting on the toilet [whether you are reading or just sitting there] for a prolonged period of time can definitely lead to hemorrhoid problems.
  • Use a Squatting Position: Elevating your feet on a stool while sitting on the toilet can help mimic a squatting position, making it easier to pass stools without straining.

Lifestyle Changes

Incorporating certain lifestyle changes can help maintain overall health and reduce the risk of anorectal disorders.

  • Exercise Regularly: Regular physical activity promotes healthy bowel movements and reduces the risk of constipation. Aim for at least 30 minutes of moderate exercise most days of the week.
  • Maintain a Healthy Weight: Being overweight can increase the pressure on the pelvic and rectal veins, leading to hemorrhoids. Adopting a balanced diet and regular exercise can help you achieve and maintain a healthy weight.
  • Practice Good Hygiene: Gently clean the anal area with water and mild soap after bowel movements. Avoid using rough or scented toilet paper, which can cause irritation.
