Stage 3 kidney disease means that the body’s kidneys are not working as well as they once did. This can be due to ageing or different types of diseases that have affected the kidneys. This illness is characterised by fatigue and headaches.
Stage 3 kidney disease results in a glomerular filtration rate (GFR) of 30 to 59, which the National Kidney Foundation defines as a moderate decrease in kidney function. Learn more about the diagnosis and management of this condition to better understand its effects.
As kidney function declines, the kidneys lose their ability to filter wastes and maintain normal fluid and electrolyte levels. This causes abnormal potassium, sodium, phosphorus, creatinine and blood urea nitrogen (BUN) levels. Patients with hyponatremia (low sodium levels) must restrict their fluid intake to avoid dangerous complications. Kidney disease contributes to the development of diabetes and hypertension, making early detection and proper treatment essential for preserving kidney function and reducing the risk of complications.
Treatment for this kidney disease stage is designed to prevent complications and preserve existing kidney function. You doctor may recommend a special diet that restricts the intake of phosphorus and potassium. This diet is necessary because people with kidney disease cannot maintain normal levels of these substances in the blood. Restricting your sodium intake prevents fluid retention, swelling and high blood pressure (hypertension). If you have developed high blood pressure as a result of your condition, your doctor will prescribe medications to control your blood pressure and reduce the risk of serious complications.
