The kidneys are located under the ribs, and their function is to cleanse 150 quarts of blood on a daily basis. Moreover, they eliminate toxins, while eliminating extra fluids and waste from the body, so they are of high importance for overall health. The kidneys also control the electrolytes in the body, and thus regulate blood pressure, maintain the bone strength, and multiply the red blood cells. Therefore, if their function is impeded due to some cause, the entire body suffers. Due to all this, you need to know these 6 signs that the kidneys are endangered:-- Fatigue- When the function of the kidneys is good, they naturally produce a hormone known as EPO (erythropoietin) which creates more blood cells and transports the oxygen all around the body. On the other hand, if the number of red blood cells is reduced, the person suffers from anemia, which is manifested with fatigue in the body, brain and the muscles. -Pain- If you suffer from pain in the upper back, where the kidneys are located, they might be in danger, and you might have kidney stones.-Swellings- When the function of the kidneys is poor, fluids remain in the body, leading to swellings around the joints, limbs, and on the face. -- Skin rash- The excessive levels of waste and fluids in the body lead to skin rashes and kidney diseases. The waste goes directly to the blood, causing skin issues. -Changes in the urine – If the color of the urine is dark, foamy, or pale, and if you experience issues while urinating, your kidneys do not work properly. -Metallic mouth taste- If the blood waste accumulates in the body, it leads to bad breath and taste in the mouth. You might also experience appetite changes. If you experience these signs, you should change your dietary habits, increase the antioxidant intake, and take supplements.
