What Is Chronic Kidney Disease in Elderly?
Chronic kidney disease affects millions of seniors and increases risk of serious complications. Understanding CKD helps seniors manage this progressive condition and protect remaining kidney function.
Understanding Chronic Kidney Disease
Chronic kidney disease means kidneys are damaged and cannot filter blood as well as they should. Waste products accumulate in the body. Kidney function is measured by glomerular filtration rate, or GFR.
CKD is staged by GFR levels. Stage 1 and 2 have mild reduction. Stage 3 is moderate. Stage 4 is severe. Stage 5 is kidney failure requiring dialysis or transplant.
CKD is common in seniors. About 40 percent of adults over 70 have some degree of CKD. Many do not know it because early stages have no symptoms.
Causes of CKD
Diabetes is the leading cause. High blood sugar damages kidney blood vessels over time. About 40 percent of diabetics develop kidney disease.
High blood pressure is the second leading cause. Uncontrolled pressure damages delicate kidney structures. Blood pressure control protects kidneys.
Other causes include glomerulonephritis, polycystic kidney disease, prolonged obstruction, and recurrent infections. Sometimes the cause is unclear.
Symptoms of CKD
Early CKD has no symptoms. Damage occurs silently. Screening identifies CKD before symptoms appear.
As CKD progresses, symptoms develop. Fatigue, swelling, decreased urination, difficulty concentrating, poor appetite, and muscle cramps occur. Severe CKD causes nausea, itching, and shortness of breath.
Complications of CKD
Cardiovascular disease is the greatest risk. CKD dramatically increases heart attack and stroke risk. Most people with CKD die from cardiovascular causes rather than kidney failure.
Anemia develops as kidneys produce less erythropoietin. Fatigue and weakness result from insufficient red blood cells.
Bone disease occurs from mineral imbalances. Calcium and phosphorus regulation is impaired. Bones become weak.
Fluid and electrolyte imbalances cause swelling and dangerous potassium elevations.
Managing CKD
Blood pressure control protects kidneys. Target blood pressure is typically below 130/80. ACE inhibitors or ARBs are preferred medications as they protect kidneys specifically.
Blood sugar control in diabetics slows progression. Tight glucose control reduces kidney damage.
Dietary modifications help manage CKD. Limiting sodium, phosphorus, and potassium may be needed. Protein restriction is sometimes recommended for advanced CKD.
Avoiding nephrotoxic medications protects kidneys. NSAIDs, certain antibiotics, and contrast dye can damage kidneys. Alert providers about your CKD.
Regular monitoring tracks progression. Kidney function tests, blood pressure monitoring, and urine tests guide management.
