1 Cup to Detox and Cleanse...So Your Kidneys Never Give Up! Dr. Mandell

Signs and symptoms of chronic kidney disease develop over time if kidney damage progresses slowly. Loss of kidney function can cause a buildup of fluid or body waste or electrolyte problems. Depending on how severe it is, loss of kidney function can cause:
Nausea
Vomiting
Loss of appetite
Fatigue and weakness
Sleep problems
Urinating more or less
Decreased mental sharpness
Muscle cramps
Swelling of feet and ankles
Dry, itchy skin
High blood pressure (hypertension) that's difficult to control
Shortness of breath, if fluid builds up in the lungs
Chest pain, if fluid builds up around the lining of the heart
Signs and symptoms of kidney disease are often nonspecific. This means they can also be caused by other illnesses. Because your kidneys are able to make up for lost function, you might not develop signs and symptoms until irreversible damage has occurred.
