An anal fissure is a tear in the delicate skin around the anus. This tear can be very painful, particularly when passing stool.
Causes
Treatment for anal fissures aims to promote healing, relieve pain, and prevent further damage. At LifePlus Hospital, we offer a range of treatment options based on the severity of your condition:
Most patients begin to feel better within the first 2-3 weeks after surgery. You may experience some discomfort during the first few days, but this usually improves significantly over time.
Complete healing can take anywhere from 6 weeks to 3 months, depending on the type of surgery and your individual healing process.
While you can typically resume light activities and work within 1-2 weeks, more strenuous activities like heavy lifting or intense exercise should be avoided for at least 4-6 weeks to avoid strain on the healing area.
The healing time for an anal fissure can vary:
Yes, anal fissures can recur, especially if the underlying causes (such as constipation, diarrhea, or straining during bowel movements) are not addressed. Long-term prevention through lifestyle changes, including dietary modifications and proper bowel habits, can help reduce the likelihood of recurrence.
Surgery is typically reserved for chronic anal fissures that do not heal with conservative treatments. The most common surgical treatment is lateral internal sphincterotomy, where a small portion of the anal sphincter muscle is cut to relieve tension and promote healing. Surgery is usually very effective, with a low risk of complications, but it’s typically considered after other treatments have failed.
Botox (botulinum toxin) injections can be used to treat chronic anal fissures by temporarily paralyzing the anal sphincter muscle. This reduces the pressure on the fissure and promotes healing. Botox is typically used for individuals who do not respond to conservative treatments but are not candidates for surgery. The effects of Botox typically last for 2 to 3 months, after which the fissure may have healed.
While you can continue most activities, you should avoid activities that might irritate the anal area or cause excessive strain, such as heavy lifting or sitting for long periods on hard surfaces. It’s also important to avoid constipation and excessive straining. Gentle exercise, such as walking, is generally fine, but any activity that causes significant discomfort should be avoided until the fissure heals.
In most cases, anal fissures heal without causing long-term issues. However, if left untreated or if they become chronic, complications may include:
