How can I tell if my urine is foamy?
Many different factors can influence the color of your urine. How much water you drink, what medications you’re taking, what food you eat, and even how vigorously you exercise can all affect urine color. Healthy urine can range in color from light to pale yellow through to dark orange.
Regardless of the color of your urine, you may notice that it sometimes takes on a foamy appearance. Foamy urine happens when many layers of small- to medium-sized bubbles appear in the urine. The bubbles happen when little pockets of gas get trapped in the urine and an organic chemical compound called a surfactant covers the space between the surrounding air and water. In urine, the surfactants that form the foam are usually proteins.
