17 Signs That You Might Have Kidney Stones

12. Nausea

Your kidneys share the same nerve network as your digestive system. Because of this, an illness or infection in your kidneys or urinary tract may affect your digestive system as well. Having a kidney stone lodged in these areas may cause pain in your abdomen. This in turn may make you feel sick to your stomach. Nausea, with or without vomiting, may be a sign that you have kidney stones. It may also be accompanied by a loss of appetite.
