Red or pink
For women, seeing a little red in your pee is a standard monthly event. But if you're seeing it at other times too, it can be the body's way of alluding to something more serious, like an infection or kidney disease. For guys, it can also be a symptom of a prostate condition.
Or it could also just be that you've eaten a lot of beets, blueberries, or rhubarb. According to Dr. Sam, there will likely be other indicators that tell you it's not coming from the pie you ate earlier.
"If it's burning or you're having a pink-reddish color, something is going on in the kidney," she says. "If you have no symptoms or burning at all, but you also haven't eaten those things, you may still want to see your doctor."
A sweet smell
If your pee starts to smell sugary, don't get too excited about this new, unusual sensation -- it could be a symptom of diabetes. Dr. Sam says it's a sign of too much glucose in the blood. If you also find yourself heading to the bathroom a little too frequently, it's definitely time to seek medical attention.
