Anal fissures are small cuts or tears that occur in the lining of your back passage, just inside your anus (anal canal). They will often develop towards the back of your anus although they also appear at the front of your anus, or even both together at the same time, causing severe anal fissure pain and sometimes bleeding when you pass faeces.
There isn’t an obvious reason why anal fissures develop and indeed it could be due to one of a number of causes. For example, constipation resulting in the forcing of a large and hard bowel movement, which could then tear the lining of the anal canal.
Other causes of anal fissures include inflammatory bowel disease (IBD), such as Crohn's disease and ulcerative colitis, pregnancy, persistent episodes of diarrhoea, and occasionally, a sexually transmitted infection (STI), such as syphilis or herpes, which may infect and damage the anal canal.
Anal fissures can eventually subside and go away by themselves using simple self-help measures like eating plenty of fibre and staying well hydrated.
However, they reoccur if they're caused by constipation that remains untreated. Some people may experience symptoms from anal fissures that last 6 weeks or even more (known as chronic anal fissures).
A prescription ointment is suitable to treat chronic anal fissures from Medical Specialists® Pharmacy to help alleviate any embarrassment. The ointment boosts the blood supply to the anus, which then relieves the pain and helps the fissure to heal.
For persistent cases of anal fissure where self-help measures (such as trying home remedies for anal fissure) and anal fissure treatment has not had the desired effect, then surgery may be required.
One of the biggest causes of anal fissure is actually through the use of painkillers. These medications can cause diarrhoea, but mainly constipation, which then can lead to an anal fissure.
