Chronic kidney disease is not one thing that happens to you. It is a rate — how fast function is being lost. Almost everything we do is aimed at slowing that rate.
What actually changes the trajectory
Most of what protects a kidney is unglamorous and enormously effective.
Blood pressure. The single largest modifiable factor. Target is generally under 120 systolic when tolerated, and getting there often takes three or four medications.
SGLT2 inhibitors. The most significant advance in kidney medicine in thirty years. Dapagliflozin and empagliflozin slow progression substantially, in patients with and without diabetes. If you have CKD with protein in the urine, you should be on one unless there is a reason you cannot be.
ACE inhibitors or ARBs. They reduce proteinuria and protect the kidney beyond their effect on blood pressure. A modest rise in creatinine after starting one is expected and is not a reason to stop.
Finerenone. For diabetic kidney disease, added on top of the above.
Glucose control, if you are diabetic.
Stopping the drugs that are hurting you. NSAIDs, certain antibiotics, contrast studies ordered without thought. A large fraction of preventable kidney injury comes from medications.
What we manage alongside it
CKD does not fail alone. Each of these is treated as its own problem, on its own schedule.
- Anemia — the kidney stops making erythropoietin
- Bone and mineral disease — phosphorus rises, calcium falls, parathyroid hormone climbs
- Metabolic acidosis — corrected with bicarbonate, which itself slows progression
- Potassium — which often constrains the very medications that protect the kidney
- Cardiovascular risk — far more CKD patients die of heart disease than reach dialysis
| Therapy | What it does for your kidneys |
|---|---|
| SGLT2 inhibitors | Slow the decline toward kidney failure and protect the heart |
| Finerenone | Lowers kidney and cardiovascular risk in diabetic kidney disease |
| ACE inhibitors / ARBs | Ease pressure inside the kidney's filters — often underdosed |
| Blood pressure & diabetes control | The foundation that everything else builds on |
Chronic kidney disease treatment by stage
The same core treatment applies at every stage. What changes is what gets added.
- Stages 1 and 2: find the cause, control blood pressure and blood sugar, and start kidney-protective drugs if there is protein in the urine. Check yearly.
- Stage 3: everything above, plus screening for anemia, acid buildup, and bone and mineral changes. Most patients should be seeing a nephrologist by now.
- Stage 4: everything above, checked more often, and the conversation about dialysis, transplant, and conservative care begins.
- Stage 5: kidney failure. Treatment is a transplant, dialysis, or conservative care, chosen ahead of time.
Advanced planning
When your eGFR falls below 30, we start talking about what comes next — not because it is imminent, but because the patients who do well are the ones who had time to choose.
Below 20, you can be evaluated for transplant and listed before dialysis ever begins. If you will need dialysis, a fistula takes three to six months to mature. Rushing these decisions is how people end up with a catheter in their neck in an emergency room.
Kidney failure treatment options
When the kidneys can no longer keep up, there are three paths. All three are worth understanding before you need one.
- Kidney transplant. The best outcomes for most patients who qualify. A transplant done before dialysis starts (preemptive) does better than one done after. A living donor shortens the wait considerably.
- Dialysis. Hemodialysis is done in a center about three times a week, or at home. Peritoneal dialysis is done at home every day, often overnight while you sleep.
- Conservative kidney care. For some older or very ill patients, dialysis adds treatment burden without adding much time. Conservative care manages symptoms, fluid, and potassium without dialysis. It is a legitimate choice, made with the patient and family.
What we track
At each visit: eGFR, urine albumin-to-creatinine ratio, potassium, bicarbonate, hemoglobin, phosphorus, calcium, and parathyroid hormone. The interval depends on your stage and how fast you are moving.
The slope of your eGFR over time tells us more than any single value. A patient at 35 who has been stable for six years and a patient at 35 who was at 55 last year are in entirely different situations.
