Can chronic kidney disease be prevented?

The kidneys filter waste and help regulate fluid, salts, and blood pressure. High blood pressure and type 2 diabetes can damage the small blood vessels and filtering units over time, especially when they are untreated or poorly controlled. Kidney injury can also follow dehydration, severe illness, urinary blockage, or harmful medicine use. Some causes are inherited or cannot be changed, so prevention means reducing avoidable strain and finding problems early. Chronic kidney disease may develop quietly, which is why routine checks matter for people with risk factors.

Attend recommended blood pressure and diabetes checks, take prescribed treatment consistently, and ask whether kidney blood or urine testing is appropriate. Avoid smoking, stay active in a way that suits your health, and choose a balanced eating pattern with sensible salt intake. Drink regularly, particularly during hot weather or illness, while following any fluid limit prescribed for you. Do not use frequent painkillers or herbal products without checking with a clinician or pharmacist. Seek advice early for repeated urinary infections or symptoms of blockage.

Arrange medical review for persistent swelling, foamy or bloody urine, changes in urination, ongoing tiredness, or unexplained nausea. Seek urgent help for severe breathlessness, confusion, very little urine, or sudden swelling after an illness or new medicine. Do not wait for symptoms if you have diabetes, hypertension, or a strong family history of kidney disease; screening can detect changes before you feel unwell.

How often should my blood pressure, blood sugar, kidney blood test, and urine be checked? Are any medicines affecting my kidneys? What should I do during vomiting, diarrhoea, fever, or dehydration?
