Over the course of our lifetime, we around 34,000 litres of urine, according to Business Insider. Urine evacuates the nitrogen-containing waste produced by the organs and expelled into the blood, like urea and uric acid for example. It's also made up of water and mineral salts. It tends to be a clear shade of yellow, ranging from pale to dark at different times of the day.

Nevertheless, our pee can come in as many as ten different shades, which can on occasion lead to unpleasant surprises when going to the bathroom. Some are due to what we eat and drink, while others are caused by health conditions like urinary infections, diabetes or kidney stones. As we approach World Kidney Day, which falls on 9th March every year, let’s take a moment to go through all those various colours and what they may mean from a health perspective.

To start out, why is it yellow most of the time? What are the oddest colours urine can take on? What if the colour doesn’t go back to normal? In under 3 minutes, we answer your questions!
