Overview
- New articles highlight existing guidance from Healthline, the Liver Foundation, Diabetes.co.uk and Kidney Care UK on when foot itching warrants medical review.
- Liver disease can cause widespread itching without a rash, often worse at night or in heat, with experts noting the exact cause remains unclear but may involve bile salts and blood mediators.
- In diabetes, itchy feet are common with prolonged high blood sugar or complications such as nerve damage, alongside symptoms like excessive thirst and frequent urination.
- Kidney Care UK reports itching affects about half of people with advanced kidney disease and almost everyone on dialysis, with triggers including dry skin, high temperatures, inadequate dialysis and raised calcium levels.
- Doctors advise that occasional itch is usually benign, but persistent symptoms accompanied by fatigue, jaundice, swelling or urinary changes should prompt testing.
