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.
Stage 3 Kidney Disease Causes
Causes of chronic kidney disease include diabetes, high blood pressure, chronic illnesses, autoimmune disorders, damage to the structures of the kidneys, polycystic kidney disease, severe kidney infection, drugs, industrial toxins and congenital defects. Acute renal failure is classified as prerenal, renal and postrenal. Prerenal causes of kidney failure include severe dehydration, heart attack, pulmonary embolism, liver failure, septic shock and renal artery obstruction. Renal causes of acute kidney failure include injury to the kidney tubules, hemorrhage, surgery, toxins and immune disorders. Postrenal causes of kidney failure include bladder obstruction, ureter obstruction and congenital defects. Acute renal failure can lead to chronic kidney disease if it is not treated quickly.
Stage 3 Kidney Disease Treatments
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.
Stage 3 Kidney Disease Symptoms
Fatigue: Feeling tired is common for people with CKD and is often caused by anemia.
Too much fluid: The kidneysmay lose their ability to control how much fluid stays in the body. A person may notice swelling (edema) in their lower legs, hands or face around the eyes. With too much fluid someone could even feel short of breath.
Urination changes: Urine may be foamy if there is protein in it, or dark orange, brown, tea colored or red if it contains blood. A person may urinate more or less, or get up at night to go to the bathroom.
Kidney pain: Most people with CKD do not have kidney pain, but with some kinds of kidney problems, such as polycystic kidney disease (PKD) or infections, they may have pain in their back where the kidneys are.
Stage 3 Kidney Disease Diet
Someone with Stage 3 CKD may want to see a dietitian. A healthy diet that eliminate minerals like sodium, phosphorous and magnesium is essential, since those products are difficult for kidneys to process and put extra strain on the body and kidneys when they accumulate in the bloodstream. The diet should also regulate the amount of protein that is taken in each day and include a variety of fruits, grains and vegetables. And a healthy eating plan should keep foods with saturated fat and cholesterol at a minimum. Since each patient is different, there is no set diet plan for Stage 3 CKD, and that’s why it’s important to consult an expert who can
