14Nausea
If you are experiencing an unsettled stomach, then it might be caused by an infection in your kidneys. In fact, this is a common sign of chronic kidney disease and other similar conditions. The reason is that these organs play the main role in getting rid of waste and toxins from your body. Thus, when the infection impairs their normal functions, your body cannot eliminate these harmful substances as usual. As a result, the body might find another way to achieve this goal. By causing nausea and vomiting, the brain is trying to signal that your body needs to remove waste as soon as possible to prevent further complications. [14]
