Anal fissure: What is it, how to identify and treatment

A anal fissure is a small wound that arises in the anus, like a cut that is located at the entrance of the anus, and causes symptoms such as pain, discomfort, minor bleeding and burning when defecating.

This type of crack is usually caused by the passage of very dry and hard stools that dilate the sphincter, causing injury. However, other problems such as obstipation, severe diarrhea, intimate anal contact, genital herpes or hemorrhoids can also lead to the development of a fissure.

The most important in the treatment of anal fissure is to maintain adequate intimate hygiene, to prevent the emergence of infections that make healing difficult. Whenever possible, after defecating or urinating, the area should be thoroughly rinsed with water and a little intimate soap or wiped with moistened toilet paper.

In addition, applying cold water compresses on the fissure region may also be an option as they calm the burning and reduce the pain, but other strategies are:

Ointments anal fissure

Ointments should be used during treatment when symptoms are very intense and cause a lot of discomfort to defecate. So, some examples of ointments are:

  • Proctyl or Ultraproct: are ointments that contain an anesthetic substance that reduces pain sensitivity;
  • Rectogesic and other nitroglycerin ointments: aids in anal sphincter relaxation and can improve blood circulation in the region, facilitating healing of the fissure;
  • Bepanthol: These are healing ointments that can moisturize and stimulate skin healing.

These ointments should always be indicated by a proctologist as they should be appropriate to each person's symptoms and the specific cause of the anal fissure.

In the most severe cases, when the anal fissure is large and deep, it may be necessary to see the doctor so that he may indicate oral painkillers and anti-inflammatory drugs like Paracetamol or Naproxen for pain and inflammation relief, or antibiotics such as Amoxicillin, Neomycin. or Gentamycin for example to treat possible infections.

Anal fissure seat bath

Sitting completely naked for 20 to 30 minutes in a basin of warm water and a bag of chamomile or lavender tea is a great way to alleviate the discomfort caused by the fissure and aid in its healing. Other medicinal plants that can also be used for this seat bath are calendula or witch hazel, which are also indicated in case of hemorrhoids.

How to correctly identify the anal fissure

Some of the symptoms that indicate the presence of an anal fissure include:

  • Pain in the region of the anus fissure, especially when paper hygiene is performed;
  • Presence of blood remains on the paper or wet tissue used for hygiene;
  • Blood in the stool;
  • Burning, especially when urinating or defecating;
  • Frequent itching in the anus.

The anal fissure wound can cause anal sphincter spasm which makes it difficult to evacuate and in the most severe cases there may even be blood in the stool. In children and infants, anal fissure may worsen constipation because it causes pain, and it may be advisable for the child to use some natural laxatives to make the stools softer and their output favored.

How to prevent the crack from arising again

Most of the time, anal fissures are caused by very dry stools and obstipation, so it is recommended you invest in a balanced, high fiber diet and to rely on regular physical activity to help regulate the bowel.

However, to avoid dry stools it is very important to drink enough water.
