A fistula is an abnormal connection or passageway that occurs between two organs, vessels, or tissues within the body. It can develop as a result of various health conditions, injuries, or surgical procedures.
Fistulas can occur in different parts of the body, each with its own set of symptoms and complications. Understanding the different types of fistulas and their symptoms is essential for early detection, accurate diagnosis, and effective treatment.
1. Anal Fistula
An anal fistula is an abnormal connection that forms between the inner lining of the anal canal and the skin around the anus. It usually occurs as a result of an infected anal gland or an anal abscess that has not healed properly.

2. Vaginal Fistula
A vaginal fistula is an abnormal opening that develops between the vagina and another organ, such as the bladder, rectum, or urethra.

- Involuntary leakage of urine
- Frequent urinary tract infections
- Decreased urine output
- Irritation and redness of the vaginal area
4. Rectovaginal Fistula
A rectovaginal fistula is another type of vaginal fistula that connects the rectum and the vagina. It can occur as a result of conditions such as Crohn’s disease, radiation therapy, or childbirth injuries.
