If a person’s internal body temperature increases — for instance, if they have a fever caused by an infection or if they have just done intense exercise — then their urine may also be warmer than usual.
Below, we provide a list of causes for hot urine or burning urination.
Urinary tract infection (UTIs): Urinary tract infections are among the most common reasons why urination feels hot or burns when coming out. A UTI occurs when harmful bacteria, often E. coli, get into the urinary tract.
UTIs most commonly affect the bladder. People with UTIs may experience the following symptoms:
- burning pain when they urinate
- a frequent need to urinate
- an intense urge to urinate even immediately after going
- foul-smelling urine
- blood in the urine
In most cases, antibiotic treatment quickly cures a UTI. Left untreated, the infection can spread to the kidneys or other areas of the body. UTIs can affect both saxes, but are more common in women than in men.
One of the ways that the body fights infection is by heating up. This is why people often develop fevers when they are sick. When the urine is a higher temperature than usual, this could mean that a person has a fever.
A fever could be due to an infection anywhere in the body, so it is important to track symptoms and see a doctor if they do not get better.
When the urine feels physically warm and it burns to urinate, this may mean someone has a UTI or an infection in the kidneys.
Injuries near the urethra
Urine is acidic. This means that when it comes into contact with an injury, even a small one, a person may experience a hot, burning sensation. An injury in or around the urethra can cause the urine to feel hot coming out.
People who shave their genitals may have tiny cuts near the urethra. Friction-related injuries from saxual intercourse, tiny pimples, cuts, and scrapes can all make the urine feel hot.
Small injuries usually go away on their own. If the urethra hurts, a fever occurs, or there is a large wound, a person should see their doctor.
Interstitial cystitis is a poorly understood chronic illness that causes symptoms of a UTI, even when a UTI is not present.
This condition is more common in women than in men.
Researchers do not fully understand what causes it, but one potential cause is damage to the tissue of the bladder. People with interstitial cystitis may experience burning when urinating, or other unusual sensations, such as a feeling that the urine is too hot.
Causes in men
Causes specific to men include:
Prostatitis is swelling, pain, and inflammation in the prostate, often due to a bacterial infection. Men with prostatitis may experience pain or burning when urinating, as well as changes in the flow of urination.
They may also have nausea and vomiting, or pain during ejaculation. It is important to diagnose the cause of prostatitis, so men who suspect they have a prostate issue should see a doctor.
The epididymis is a tube that contains the sperm on top of the testes. An infection or inflammation in this tube can cause painful burning when urinating. Men with epididymitis may also experience swelling around the testicles, pain in the penis or testicles, and a fever.
This painful condition is usually caused by a bacterial infection or surgery and responds well to antibiotics and rest.
