In chronic kidney disease, what are the two most important modifiable risk factors that influence progression?

• A. Hypertension and Proteinuria
• B. Diabetes mellitus and Hyperlipidemia
• C. Anemia and Hypokalemia
• D. Age and Sex

Answer: (A)

Controlling what happens inside the kidneys hinges most on two modifiable factors: blood pressure and the amount of protein leaking into the urine. Hypertension accelerates kidney damage by stressing the delicate renal vasculature and promoting nephron loss, so lowering blood pressure slows this injury and helps preserve kidney function. Proteinuria reflects ongoing glomerular injury and, in turn, drives further tubulointerstitial damage; reducing proteinuria—primarily with therapies that block the renin-angiotensin system such as ACE inhibitors or ARBs—not only lowers pressure but directly mitigates the protein-related damage, markedly slowing progression. Together, these interventions have the strongest impact on the trajectory of CKD compared with the other factors listed. The remaining items are less directly tied to the rate of kidney decline in established CKD (though they matter for overall health and cardiovascular risk).
