They also control the body’s salt, potasssium and acid in the body. Hormones are also produced by the kidneys to help control blood pressure, stimulate red blood cell’s and help control the metabolism of calcium.

Stage I is normal kidney function, where there are usually no signs and symptoms, although high blood pressure can occur. Stage II is mild kidney damage, where there may be a slight decrease in GFR(60-89), with some high blood pressure, slightly elevated creatinine and urea levels. Stage III is moderate kidney damage with symptoms similar to stage II, but slightly lower GFR (30-59). Stage IV is severe kidney disease, where your GFR will be significantly lower than normal (15-29), high potassium levels, metabolic acidosis; which can affect your breathing and your heart. High phosphate levels can occur, causing muscle spasms, cramping and irregular heart beat. Finally, stage V is end-stage kidney disease, where you will experience severe signs and symptoms (GFR of < 15) (Huether & McCance,
