What should you know about IRIS chronic kidney disease?

The kidneys filter waste and help regulate fluid, salts, blood pressure, and red blood cell production. With chronic kidney disease, these jobs may become less efficient over time. IRIS is a kidney-focused framework clinicians may use alongside blood pressure, urine findings, blood tests, and the underlying cause to describe kidney disease and guide monitoring.

Early kidney disease may cause few noticeable symptoms. As kidney function changes, some people develop fatigue, excessive thirst, swelling, changes in urination, itching, nausea, or sleep and concentration problems. These symptoms can have several causes and do not establish kidney disease by themselves.

Type 2 diabetes and hypertension can damage the kidneys, while kidney disease can contribute to anaemia, gout, and restless legs symptoms. Managing linked conditions is part of protecting health.

Keep scheduled blood and urine 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 interfere with treatment. Keep your care team informed about new medicines and changes in urination, swelling, appetite, or energy.

Work with your clinician on blood pressure, diabetes, salt intake, fluids, activity, and dietary needs. The right fluid and protein advice depends on kidney function and other conditions, so avoid making major restrictions without individual guidance.

Seek urgent medical help for severe breathlessness, chest pain, confusion, fainting, sudden marked swelling, very little or no urine, or repeated vomiting with weakness. Contact your kidney team promptly if urine changes suddenly, blood appears in the urine, or you develop rapidly worsening fatigue or thirst.

Ask what your kidney tests show, how often they should be repeated, whether blood pressure or diabetes is affecting kidney health, which medicines require review, and what symptoms should trigger same-day advice.
