What does dark urine in men mean?

The quality of your urine can say a lot about your health, especially dark urine in men. Dark urine in men can indicate a variety of problems, some of which are serious and some are not. Either way, it’s better to err on the side of caution. Men with dark urine should get symptoms checked out.

Possible Causes of Dark Urine in Men

Various conditions, illnesses, and external factors can alter the color, odor and consistency of your urine. Dark urine can be caused by the following:

  • Hepatitis B and other strains of hepatitis
  • Certain vitamins or supplements
  • Dehydration
  • Cirrhosis of the liver, a complication of hepatitis B and other conditions
  • Gallstones
  • Kidney stones


Since dark urine in men can be caused by hepatitis B, STD testing is highly recommended. Testing for hepatitis B is routinely recommended for men who have sex with other men. Hepatitis B testing is performed through a quick blood sample at a local lab, and results are available within a few short days.

If your hepatitis B testing and STD testing comes back negative, a doctor can help diagnose other possible conditions with further testing. Take note of any vitamins you are taking and how much fluids you drink since they may be affecting the color of your urine.


When caused by hepatitis B, dark urine in men depends on whether the infection is acute or chronic. An acute hepatitis B infection doesn’t require any specific treatment, while antiviral medication can help manage chronic infections. If you test negative for hepatitis B, be sure to follow up with the hepatitis B vaccine.

Treatment for gallstones depends on the severity of the condition. Some patients require surgery, but others may not require any medical treatment. Kidney stones have to pass with time, but fluids and pain medication can help. A doctor must treat and monitor cirrhosis.

If dehydration is causing dark urine in men, drinking more fluids can help. If vitamins or supplements are the cause, consult your doctor to see if your supplements are safe.
