In its May 2025 resolution, the WHO declared chronic kidney disease one of the fastest-growing causes of death. The agency projects CKD will become the fifth leading cause of death worldwide by 2050.
Unfortunately, Filipinos discover the problem only after significant damage to their kidneys. Understanding the 5 CKD disease stages helps you understand this renal disease, ask the right questions, and act before damage becomes permanent.
What is Chronic Kidney Disease?
Chronic kidney disease, or CKD, is a long-term loss of kidney function that progresses over months or years. Healthy kidneys filter waste products from your blood, balance minerals, and regulate blood pressure. When kidney function slows down, the whole body feels it.

Most Common Causes of Chronic Kidney Disease
Most cases of CKD start with other chronic conditions damaging the kidneys quietly over years. Watch for these chronic conditions that can cause chronic kidney disease:
- Diabetes: High blood sugar damages the small filters inside the kidneys, the leading cause of kidney failure globally.
- Hypertension: Uncontrolled high blood pressure strains the kidneys’ blood vessels and accelerates loss of kidney function.
- Glomerulonephritis: Inflammation of the kidney’s filtering units, often triggered by infections or autoimmune disease.
- Polycystic kidney disease: An inherited condition that grows cysts inside the kidneys and gradually replaces healthy tissue.
- Recurrent kidney problems: Repeat urinary infections, kidney stones, and obstructions that scar the kidneys over time.
NOTE: Family history of kidney disease is among the strongest risk factors for CKD, even without another cause. If anyone from your family was diagnosed with CKD, it’s best to be extra careful of your kidney health.

The 5 CKD Disease Stages Explained
CKD is staged using your estimated glomerular filtration rate (eGFR). The eGFR comes from a routine blood test that measures how well your kidneys filter waste. Using the test results, experts can track the severity and scale them in five stages of chronic kidney disease.
Stage 1: Kidney Damage with Normal Function (eGFR 90 or Higher)
At stage 1, your eGFR still looks normal. The flag comes from urine tests, imaging, or a known family history of kidney disease that shows evidence of kidney damage. Most patients feel fine and have no noticeable symptoms.
Early detection at this stage gives you the most options. Tight blood pressure and blood sugar control with lifestyle changes can keep your kidneys at this level for years.
Stage 2: Mild Loss of Kidney Function (eGFR 60 to 89)
Your eGFR slips slightly into the 60-89 range. Signs of kidney damage show up only in urine or imaging, and most patients learn about it through routine blood work.
The treatment plan looks similar to stage 1. Your kidney specialist will treat the cause of your kidney disease directly. Diabetes and hypertension are the usual culprits.
Stage 3a and 3b: Moderate Loss of Kidney Function (eGFR 30 to 59)
Moderate kidney function loss covers a wide range. Stage 3a covers an eGFR of 45 to 59. Stage 3b covers 30 to 44.
This is when many patients first notice symptoms. Fatigue, swelling in the ankles, foamy urine, and changes in urination are common. Your doctor will also check for anemia, bone disease, and high potassium.
Kidney specialists usually tighten dietary salt, protein, and potassium limits. ACE inhibitors or ARBs may be added to protect remaining kidney function.
Stage 4: Severe Loss of Kidney Function (eGFR 15 to 29)
This is the last stage before kidney failure. Symptoms become harder to ignore. Expect swelling, nausea, poor appetite, trouble concentrating, and shortness of breath.
Your kidney specialist will start discussing potential kidney replacement therapy so you can plan ahead. Vascular access for hemodialysis or a peritoneal dialysis catheter takes weeks to set up. A kidney transplant evaluation can take months.
Stage 5: Kidney Failure (eGFR Less Than 15)
At stage 5, the kidneys can no longer filter waste effectively. It is also called end-stage renal disease.
Treatment requires kidney replacement therapy. These are hemodialysis, peritoneal dialysis, and kidney transplantation. Centers like the National Kidney and Transplant Institute coordinate dialysis options and transplant evaluations.
Treatment Plans Across the Stages of CKD
A treatment plan for kidney disease is built around two goals: slow the damage and protect remaining kidney function. Doctors usually combine several treatment options depending on the stage:
- Blood pressure control: ACE inhibitors or ARBs lower pressure and protect the kidneys’ tiny filters.
- Blood sugar management: Tight glucose control with a diabetes doctor slows kidney damage from diabetes.
- Lifestyle changes: Quitting smoking, keeping a healthy weight, cutting salt, and limiting the amount of protein take pressure off the kidneys.
- Anemia treatment: Erythropoietin helps the body produce red blood cells when failing kidneys can no longer trigger this on their own.
- Bone and mineral medications: Phosphate binders manage the mineral imbalance that develops in stages 3 to 5.
- Diuretics: These ease swelling caused by fluid buildup in advanced stages.
- Kidney replacement therapy: Stage 5 requires hemodialysis, peritoneal dialysis, or a kidney transplant.

Frequently Asked Questions About CKD Disease Stages
What is the difference between early stages and advanced stages of kidney disease?
Early stages (1 and 2) usually have no symptoms and are caught through routine blood and urine tests. Advanced stages (4 and 5) cause swelling, fatigue, and nausea, and may require dialysis or a kidney transplant.
Can early-stage CKD be reversed?
Existing kidney damage usually cannot be undone, but disease progression can be slowed dramatically when CKD is caught early. Tight blood pressure and blood sugar control plus lifestyle changes are the most effective tools.
How often should I get my kidneys checked if I have a family history of kidney disease?
Most kidney specialists recommend yearly routine blood and urine tests for adults whose medical history includes a family history of kidney disease, diabetes, or hypertension. Earlier and more frequent close monitoring may be advised if you already show signs of kidney damage.
What is the most common cause of chronic renal disease in the Philippines?
Diabetes and hypertension are the two leading causes of chronic kidney disease in the Philippines, mirroring global patterns. Routine screening of patients with either condition is the most effective way to catch CKD before it progresses.
Conclusion
The 5 CKD disease stages give you and your doctor a shared map of how your kidneys are doing. From the early stages of kidney disease to the late stages of kidney failure, knowing your eGFR turns a vague worry into a concrete plan: control the causes, track your test results, and adjust the treatment plan.
