Balanitis

Also called Inflamed foreskin or Balanoposthitis

Balanitis is when the head of the penis becomes red, swollen and sore. It is most common in people who have not been circumcised, and it can affect both children and adults. It is usually not serious and gets better with simple treatment.

What it is

Causes include thrush, bacterial infection, irritation from soaps, and skin conditions. In adults, repeated balanitis can be a sign of diabetes.

Gentle washing with water, avoiding soap, and creams to treat infection or inflammation usually clear it up.

Common signs

  • Redness, swelling and soreness of the head of the penis
  • Itching
  • Discharge or an unpleasant smell under the foreskin
  • Pain when peeing

How it is usually diagnosed

  • Examination
  • A swab to check for infection
  • A urine or blood sugar test to check for diabetes

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Swab results
  • Blood sugar results
  • Notes of each episode and treatment used

Questions to ask your doctor

  • What is causing it?
  • Should I be tested for diabetes or sexually transmitted infections?
  • What can I do to prevent it coming back?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Being unable to pee
  • A foreskin stuck pulled back with the head of the penis swollen (paraphimosis): go to an emergency department
