A burning sensation when peeing, medically called dysuria, is commonly caused by infections or inflammation in the urinary tract or nearby areas. The main causes include:

• Urinary tract infections (UTIs), which affect the bladder, urethra, or kidneys. Symptoms often include burning, frequent urge to urinate, and cloudy or foul-smelling urine. Untreated UTIs can lead to serious kidney infections.

• Vaginal infections such as yeast infections or bacterial vaginosis, which cause inflammation near the urethra and result in burning during urination.

• Sexually transmitted infections (STIs) like chlamydia, gonorrhea, or genital herpes, which can inflame the urethra or genital area and cause pain when urinating.

• Other causes include irritation from chemicals or allergens (such as spermicides or soaps), kidney stones, urethral stricture, prostatitis, or non-infectious inflammatory conditions.

If experiencing burning during urination, it is important to get evaluated by a healthcare professional for proper diagnosis and treatment, especially if accompanied by fever, back pain, or blood in urine. Treatments vary depending on the cause and may include antibiotics, antifungals, or other targeted therapies.
