Overview

Chronic kidney disease (CKD) is a progressive condition in which the kidneys gradually lose their ability to filter waste and excess fluid from the blood. It affects approximately 37 million Americans and is most commonly caused by diabetes and hypertension. CKD often has no symptoms until it is advanced — making regular lab monitoring essential. With proper management, the progression of CKD can be significantly slowed.

Key Points

CKD is staged 1–5 based on eGFR (estimated glomerular filtration rate) — stage 5 is kidney failure requiring dialysis or transplant.
Urine albumin-to-creatinine ratio (UACR) detects early kidney damage before eGFR declines.
SGLT2 inhibitors (empagliflozin, dapagliflozin) slow CKD progression in patients with or without diabetes.
Blood pressure control below 130/80 is one of the most important interventions for slowing CKD.
Certain medications (NSAIDs, some antibiotics, contrast dye) are harmful to kidneys and should be avoided or used cautiously.

Signs & Symptoms

Early CKD: usually no symptoms — detected through labs (eGFR, creatinine, urine albumin)
Moderate CKD: fatigue, decreased appetite, mild swelling in legs or ankles
Advanced CKD: nausea, vomiting, difficulty concentrating, decreased urine output
Foamy or bubbly urine (protein in urine)
High blood pressure that is difficult to control

Causes & Risk Factors

Diabetes — the leading cause of CKD in the United States
Hypertension — the second leading cause; damages kidney blood vessels over time
Glomerulonephritis — inflammation of the kidney's filtering units
Polycystic kidney disease — genetic condition causing cyst formation
Recurrent kidney infections, prolonged NSAID use, or obstructive uropathy

Treatment Options

1Blood pressure control with ACE inhibitors or ARBs — also reduce protein leakage into urine

2SGLT2 inhibitors (empagliflozin, dapagliflozin) — proven to slow CKD progression

3Blood sugar optimization in diabetic CKD patients

4Dietary modifications: reduced sodium, protein, potassium, and phosphorus as CKD advances

5Regular labs (eGFR, creatinine, potassium, UACR) every 3–6 months to monitor progression

When to See a Doctor

If you have diabetes or hypertension, ask about annual kidney function screening at your next visit. If you have been diagnosed with CKD, follow up every 3–6 months. Seek urgent care for sudden decrease in urine output, severe swelling, or confusion — these may indicate acute kidney injury.
