Kidneys, when they filter waste and excess water from the body, produce a yellowish liquid: urine. This can be a different colour depending on its concentration and can range from pale yellow to dark amber, but what happens when your urine is too dark? Changes in urine colour may be a sign of a purely temporary condition or, conversely, the presence of a more serious health problem. If you're asking yourself why you have dark urine keep reading this OneHowTo article in which we explain the most common causes of this condition.

Steps to follow:

In some cases, having dark urine is a temporary and temporary condition due to the consumption of certain foods or medications that may alter both the smell and the colour that it usually has. For example, when urine has a dark yellow hue it is probably due to an excessive consumption of foods containing vitamin B and carotene. It can also have this colour if you've recently taken prescription drugs for urinary tract infections or laxatives.


When your urine is dark for more than one or two days and this happens repeatedly, you will need to consult a doctor to determine the exact cause. The doctor will make a physical examination and an analysis of a urine sample, since this will be the best way to indicate the presence of a health problem.


One of the possible answers to the question of why you have dark urine is associated with dehydration. Insufficient fluid intake and excessive loss of water from the body causes urination to become darker than usual and also to have a stronger and more intense smell. It is important to drink the daily amount of water recommended by specialists in order to maintain good health and prevent the formation of kidney stones.

Urinary tract infections such as cystitis are another common cause of a change in urine colour, turning it murkier and darker. As well as this change in colour there may appear other symptoms such as a frequent and urgent desire to urinate, pain, burning or itching during urination and, in more severe cases, fever, vomiting and nausea.
