Symptoms of kidney damage include nausea, vomiting, loss of appetite, low urine flow and swelling in the legs, states WebMD.com. An individual suffering from kidney damage can also experience flank pain, restlessness, anxiety and confusion.
Depending on the type or extent of the kidney damage, symptoms can also include itching, muscle cramps, problems sleeping, chest pain and shortness of breath, explains MayoClinic.org. These symptoms are often associated with kidney damage that occurs because of chronic kidney disease. This disease is more difficult to diagnose in early stages because there are relatively few, specific symptoms. Kidney damage because of chronic kidney disease occurs for several reasons among which are diabetes, high blood pressure and kidney infections. Chronic kidney disease can be treated by treating the cause and underlying conditions. For instance, people can take blood pressure medications, lower their cholesterol levels, and eat low-protein foods.
Kidney damage can also occur because of certain medications, poison, infections or injury, according to WebMD.com. Some antibiotics, pain medications and blood pressure drugs can harm the kidneys. Dehydration and kidney stones can also cause damage. Sometimes treatment requires antibiotics to treat kidney infections or a removal of kidney stones or other blockages. More severe damage can result in dialysis.
