A burning sensation when urinating is commonly referred to as dysuria and can be caused by many different factors. The most common causes are as follows:

1. Infections

• Urinary Tract Infection (UTI): This is one of the most common causes. It may be accompanied by symptoms such as frequent urination, cloudy or foul-smelling urine, and groin pain.
• Prostatitis: Inflammation of the prostate in men can also cause a burning sensation when urinating.
• Sexually Transmitted Infections (STIs): Infections such as gonorrhea, chlamydia, and herpes can cause dysuria.

2. Stones and Blockages

• Kidney or bladder stones: These can cause irritation and a burning sensation in the urinary tract.
• Urethral strictures: These can develop especially following infections or trauma.

3. Inflammatory and Irritant Causes

• Chemical irritation: Soaps, shower gels, spermicides, or scented pads can irritate the urinary tract.
• Interstitial cystitis: A chronic inflammation of the bladder that may present with a burning sensation during urination and frequent urination.

4. Other Reasons

• Diabetes: High blood sugar can increase the risk of urinary tract infections.
• Hormone deficiencies: A decrease in estrogen after menopause can cause dryness and a burning sensation in the urinary tract.

What Should You Do?

If the burning sensation lasts longer than a few days, or if you have additional symptoms such as a fever, bloody urine, or severe pain, you should see a urologist. Tests such as a urinalysis, urine culture, and, if necessary, an ultrasound may be performed to make a diagnosis.
