CKD stage awareness
Informed by recognized medical guidance
Overview
Chronic kidney disease (CKD) means your kidneys are damaged and cannot filter blood as well as they should. There are five stages, from mild (stage 1) to kidney failure (stage 5). Knowing your stage helps you and your doctor plan the best care.
Key facts
- CKD is often silent — you may not feel symptoms until later stages.
- Stage awareness helps slow kidney damage and prevent complications.
- CKD can be managed with lifestyle changes and medical care.
Yes, CKD affects about 1 in 7 adults worldwide.
Anyone can develop CKD, but it is more common in people with diabetes, high blood pressure, and older adults.
Symptoms
- Sudden shortness of breath
- Chest pain
- Seizures
- Loss of consciousness
- ⚠Very little or no urine
- ⚠Blood in urine
- ⚠Severe headache with vision changes
Common symptoms
- Fatigue
- Swollen ankles or feet
- Changes in urination (foamy, bloody, or less often)
- Shortness of breath
- Itchy skin
- Muscle cramps
- Poor appetite
Symptoms in children
- Slow growth
- Swelling around eyes
- Frequent urination
- Bedwetting
Symptoms in older adults
- Confusion or trouble concentrating
- Fatigue
- Loss of appetite
- Swelling in legs
Causes
Main causes
- Diabetes
- High blood pressure
- Glomerulonephritis (inflammation of kidney filters)
- Polycystic kidney disease
- Long-term use of certain medicines
Risk factors
- Family history of kidney disease
- Older age
- Obesity
- Smoking
- Heart disease
When to see a doctor
See a doctor urgently if:
- If you have sudden changes in urination (very little or blood)
- Severe swelling
- Chest pain or shortness of breath
Book a routine appointment if:
- If you have diabetes, high blood pressure, or a family history of kidney disease, get checked regularly
- If you notice persistent fatigue, swelling, or changes in urination
Diagnosis
CKD is diagnosed with blood and urine tests that measure kidney function.
Tests that may be done
- Blood test for creatinine (to estimate glomerular filtration rate - eGFR)
- Urine test for albumin (protein)
- Imaging tests like ultrasound
- Kidney biopsy (rarely needed)
What to expect at your appointment
Your doctor will explain your eGFR number, which tells your kidney function level. Normal is 90 or above. Lower numbers mean worse function. Stages 1-2 are mild, stage 3 is moderate, stage 4 is severe, stage 5 is kidney failure.
Treatment
Treatment focuses on slowing kidney damage, managing complications, and preparing for future needs if the disease worsens.
Self-care at home
- Control blood pressure and blood sugar
- Eat a balanced diet with less salt and protein
- Avoid non-prescription pain relievers like ibuprofen
- Stay active and maintain a healthy weight
- Stop smoking
Medical treatments
Medicines may be prescribed to control blood pressure, protect kidneys, treat anemia, or manage other complications. In later stages, you may need dialysis or a kidney transplant.
When is surgery considered?
Surgery may be needed for a kidney transplant in stage 5.
Living with this condition
Living with CKD means checking your numbers regularly, taking prescribed medicines, and making lifestyle changes. You can still enjoy many activities.
Lifestyle tips
- Monitor your blood pressure at home
- Check your feet daily if you have diabetes
- Keep all medical appointments
- Learn about your stage and what to expect
Diet and exercise
A kidney-friendly diet often includes limiting salt, potassium, phosphorus, and protein. Work with a dietitian. Light exercise like walking is beneficial.
Mental health and emotional wellbeing
Living with a chronic condition can cause stress, anxiety, or depression. It's important to talk about your feelings with a doctor or counselor.
Prevention
Not all kidney disease can be prevented, but you can lower your risk by managing diabetes and high blood pressure, eating healthy, and staying active.
Vaccines
Stay up to date on vaccines, especially flu and pneumonia, because infections can worsen kidney disease.
Screening programmes
Routine blood and urine tests can detect early kidney disease. If you have risk factors, ask your doctor for a screening.
Complications
If left untreated
- Heart disease
- High blood pressure that is hard to control
- Anemia (low red blood cells)
- Bone disease
- Fluid buildup
- Kidney failure requiring dialysis or transplant
Long-term outlook
CKD is a serious condition, but with proper care many people live well for many years. Early stage awareness and treatment can slow progression. If kidney failure occurs, treatments like dialysis and transplant offer good quality of life.
