What should you know about KDIGO chronic kidney disease?

The kidneys filter waste and help balance fluid, salts, and blood pressure. Kidney disease can develop quietly, so clinicians use blood and urine tests, blood-pressure readings, medical history, and sometimes imaging to understand the pattern. Type 2 diabetes and hypertension can contribute to kidney damage, while reduced kidney function can be associated with anaemia, gout, restless legs symptoms, fatigue, or excessive thirst. These links do not prove that one symptom has a single cause.

Keep scheduled checks and take prescribed medicines as directed. Ask before using anti-inflammatory pain medicines, supplements, or herbal products because some can strain the kidneys or alter treatment. Keep blood pressure and blood sugar within the range your clinician recommends, avoid smoking, stay active within your abilities, and follow any individual advice about salt, fluids, and protein. A medication review is especially useful when starting a new drug or having a scan that may use contrast.

Arrange prompt medical advice for a marked change in urine, new swelling, persistent vomiting, worsening breathlessness, severe weakness, confusion, or inability to keep fluids down. Seek emergency help for severe breathing difficulty, chest pain, collapse, or sudden confusion. Rapid changes can reflect dehydration, infection, medication effects, or kidney complications and need assessment rather than home treatment alone.

Ask what your blood and urine results show, how often they should be repeated, which medicines need review, and whether you need kidney, blood-pressure, or diabetes support. Ask which symptoms should trigger same-day advice.
