A pilonidal cyst develops near the tailbone or top of the buttocks crease. It may look like a small depression or a pit. Sometimes, it may have a hollow tunnel or tract that connects it to the exterior of the skin.
Usually, a pilonidal cyst does not cause any symptoms. But, when it becomes infected, it may cause pain, itching, and inflammation.
The exact cause of pilonidal cyst isn’t known, but, changing hormones, hair growth, and friction from clothes or from sitting for a long time may induce the development of a pilonidal cyst.
Most pilonidal cysts are caused by free hairs that break in the skin. The body responds to the hair as a foreign substance and forms a cyst around the hair. The people who are more likely to get pilonidal cysts are:
There is no specific reason, but males are more prone to develop a pilonidal cyst.
Young age people
Pilonidal cysts are most common in males in their late teens or early 20s.
Having a body mass index (BMI) of 30 or more may encourage the development of a pilonidal cyst.
People with Inactive lifestyle
People who sit for a long duration of time in a position have a greater chance of developing pilonidal cysts. The continuous contact between the chair and the buttock cleft exerts pressure and increases the probability of getting a pilonidal cyst.
An occupation requiring prolonged sitting
People having a job that involves a lot of driving or sitting down for long periods are more likely to develop a Pilonidal cyst.
People with a family history of the condition
Approximately, one-third of people have a family member with the condition.
People with excess body hair
People with an above average amount of body hair are more likely to get a pilonidal cyst, which may be why more men are affected than women.
People having stiff or coarse hair
People who have coarse and curly body hair are more likely to get a pilonidal cyst.
Deep natal cleft
Having a deep cleft between your buttocks can also increase the chances of getting the problem.
People with poor hygiene
Hygiene plays a very important role in developing as well as in controlling the pilonidal cyst.
Any previous injury to the affected area of skin may be a cause of getting a pilonidal cyst.
