Pilonidal cysts are a common, often uncomfortable condition that can significantly impact an individual's quality of life. These cysts typically develop near the tailbone in the crease of the buttocks and are characterized by a sac filled with hair, skin debris, and sometimes pus. While the exact cause of pilonidal cysts isn't definitively known, ingrown hairs are widely believed to play a significant role, triggering a skin infection that may lead to cyst formation. Obesity, among other factors, has been identified as a potential risk factor in the development and management of pilonidal cysts.
Incidence and Understanding Pilonidal Disease
Pilonidal sinus disease (PSD) affects between 20 and 30 out of 100,000 people, with males being affected twice as often as females. Recent data indicates an increasing incidence across almost all age groups and both sexes in German and Turkish populations. Despite its prevalence, there is no universal consensus on the optimal treatment for rapid healing and minimal complications. PSD presents in a variety of ways, from minor asymptomatic pits to large abscesses with complex tracts and fistulas. Conservative therapies, including hair control, weight loss, hygiene and limited drainage, and surgical interventions are available. Many patients are hesitant to seek medical attention for this condition and often lack a clear understanding of what to expect after surgical removal of their pilonidal sinus.
The Role of Weight and Lifestyle in Pilonidal Cyst Development
Obesity as a Risk Factor
Obesity is considered one of the significant risk factors for developing pilonidal cysts. Excess weight places additional pressure on the lower back and tailbone, potentially leading to cyst formation. Furthermore, individuals with obesity may find it more challenging to maintain adequate hygiene in the lower back region, exacerbating the risk. In addition to overall weight, the distribution of fat can also play a crucial role. Excess fat in the lower back and buttocks increases the risk of pilonidal cysts due to added pressure and friction.
Lifestyle Choices and Prevention
Lifestyle choices, including posture, physical activity, hygiene, and sleep, can also influence the development and management of pilonidal cysts.
- Posture: Poor posture, especially during prolonged sitting, can strain the tailbone and lower back, contributing to cyst inflammation. Maintaining a straight back and avoiding slouching can help improve posture.
- Physical Activity: Regular exercise boosts circulation, protecting the tailbone’s surroundings. Low-impact activities such as swimming, cycling, and walking can strengthen the muscles around the affected area, reducing pressure and aggravation.
- Hygiene: Keeping the area clean, dry, and free from hair is essential in preventing pilonidal cysts. Unchecked hair growth around the tailbone area can trap dirt, sweat, and bacteria, increasing the risk of cyst formation.
- Sitting Habits: Prolonged sitting, especially on hard surfaces, can aggravate cysts. Alternating between sitting and standing, and using cushions or specialized pillows to reduce pressure on the tailbone, can help alleviate pain and prevent further irritation.
- Clothing: Tight clothing can rub against the affected area, causing irritation. Opting for loose, airy clothes can minimize friction and promote comfort.
Genetic Predisposition
Genetics may also play a role in the development of pilonidal cysts. Individuals with a family history of pilonidal cysts may be more prone to developing them.

Weight Loss and Conservative Management
Conservative non-surgical therapy, including weight loss, meticulous hair control through shaving, improved perianal hygiene, and limited incision and drainage for abscesses, has demonstrated effective control of PSD while promoting near-normal work status.
Impact on Activities of Daily Living
Pilonidal cysts can significantly impact daily activities. Discomfort and pain, especially during prolonged sitting, can make concentration and job completion challenging, potentially affecting a person’s ability to work or attend school. Walking or stooping can also be difficult due to swelling and pain caused by the cyst.
Treatment Options and the Influence of Obesity
While pilonidal cysts are treatable, obesity can complicate the treatment process.
Surgical Considerations
Surgery may pose additional risks for individuals with excess weight, including prolonged recovery time and a higher chance of complications such as infections or delayed wound healing. Proper post-operative care is crucial for preventing infection and promoting healing, especially following failed primary closure and when sizeable open wounds are left for healing by secondary intention. Wound healing can take over 6 months, affecting activities from personal cleansing to working and playing.
Conservative and Minimally Invasive Approaches
Conservative treatments such as drainage, warm compresses, and topical antibiotics may help manage mild cases. Minimally invasive approaches, including laser treatments, offer alternatives for pilonidal cyst removal with reduced recovery times.

Recurrence Rates
Studies suggest that individuals with obesity may have a higher rate of recurrence after pilonidal cyst surgery.
Prevention and Long-Term Management
The most effective way to prevent pilonidal cysts is to maintain a healthy weight through diet and exercise. Regular exercise prevents pilonidal cysts and improves health. Exercise boosts circulation, protecting the tailbone’s surroundings. Low-impact activities including swimming, cycling, and walking help to strengthen the muscles around the afflicted area, therefore lowering pressure and aggravation. Hygiene is also essential, especially for those with obesity. Other preventive measures include avoiding tight clothing and using cushions to relieve pressure on the tailbone during prolonged sitting.
Surgical Techniques
Many surgical techniques exist for pilonidal sinus disease, and surgeon experience should be considered in treatment decisions. When flap-based procedures are considered, the potential cosmetic outcomes should be discussed, as some techniques, like the Limberg flap, can result in unsightly scars and asymmetry. Minimally invasive approaches, such as Lord-Millar, Bascom, Gip's, EPSiT, and VAAPS, can reduce post-operative complications.
The Importance of Patient Education and Involvement
Patients should receive comprehensive verbal and written information about available surgical approaches and post-operative wound care. Understanding the potential impact of PSD on life activities and the time needed for post-surgical wound healing is crucial for managing expectations and ensuring proper care.
