Why Does It Burn When I Pee?

A burning sensation during urination is a common symptom that can be both uncomfortable and concerning. This symptom is often a sign of irritation or inflammation somewhere in the urinary tract, and it should not be ignored—especially if it does not go away within a day or two.

The most common cause is a urinary tract infection (UTI). A UTI can affect the bladder, urethra, or even the kidneys. When bacteria enter the urinary system, they irritate the lining of the bladder or urethra, causing pain, burning, or a stinging feeling during urination. UTIs are more common in women but can affect people of all ages and sexes.

Another possible cause is sexually transmitted infections (STIs), such as chlamydia, gonorrhea, or trichomoniasis. These infections can lead to burning urination, along with other symptoms like vaginal or penile discharge, pelvic pain, or discomfort during sex.

Irritation from hygiene products—such as soaps, bubble baths, feminine sprays, or spermicides—can also cause temporary burning during urination. These products may disrupt the natural balance of bacteria or pH levels in the genital area, leading to inflammation or sensitivity.

In men, prostatitis (inflammation of the prostate gland) can cause a burning feeling, often accompanied by difficulty urinating or pelvic discomfort. In both men and women, bladder stones or kidney stones can lead to sharp or burning pain as the stones move through the urinary tract.

Dehydration may also cause a burning feeling, especially when the urine becomes more concentrated. Dark-colored or strong-smelling urine may irritate the bladder or urethra. Drinking more water can sometimes help reduce this discomfort.

In rare cases, burning urination can be related to conditions such as interstitial cystitis, chemical exposure, radiation therapy, or urinary tract injury. If the burning is severe, long-lasting, or accompanied by other symptoms such as fever, blood in the urine, or lower abdominal pain, it is important to see a doctor.

Treatment depends on the cause. Infections are usually treated with antibiotics, while irritation from soaps or products may improve by switching to gentler alternatives. Identifying the exact cause is the first step toward proper care and long-term relief.
