How is balanitis caused?

Patient's question:

I got tested for a physical last week and found that I have balanitis. It seems to be getting worse recently, with some bleeding and discharge, and it looks like there are also blisters. Is the condition getting serious? Please ask: How is balanitis caused?

Doctor's answer:

According to your condition, it is inferred that the inflammation of the glans mucosa is called balanitis. This condition can be caused by various pathogens, local irritation, and other factors. Balanoposthitis refers to the inflammation of the inner foreskin and glans. A normal foreskin cavity secretes a lipid substance. When the foreskin is too long or there is phimosis, this substance can accumulate as smegma, irritating the foreskin and glans, leading to balanoposthitis. Drug allergy-induced balanitis is a delayed-type hypersensitivity reaction and is very common in clinical diagnosis. It usually occurs 24 to 72 hours after medication. Balanoposthitis manifests as redness and swelling of the foreskin, burning pain, relief during urination, and purulent discharge from the foreskin orifice.
