Inflammation of the glans (balanitis) or of the foreskin and glans (balanoposthitis) is often caused by a narrowing of the foreskin (phimosis). Sebum (smegma) forms between the glans and the foreskin, which is usually washed off as part of genital hygiene. If this secretion from the sebaceous glands remains and is broken down by bacteria, the glans and foreskin can become inflamed. Inflammation of the glans and foreskin can also be a result of non-bacterial diseases. Penis baths and antibiotic treatment are usually the suggested treatment, as well as the diagnosis and treatment of the underlying disease causing the inflammation. In case of foreskin tightness, circumcision is recommended.
