Diabetes specialists note that itching affecting the feet, ankles, and legs is common among people with diabetes. Itchy skin can be an early sign of the condition, particularly when other symptoms are present.

Prolonged high blood sugar levels can dry out the skin and lead to irritation. In some cases, itching may result from diabetes-related complications such as nerve damage or kidney problems.

Common warning signs of diabetes include:

Excessive thirst

Frequent urination, especially at night

Extreme tiredness

Weight and muscle loss

Genital itching or recurring thrush

Blurred or impaired vision

Kidney disease

Itching is also very common in people with kidney disease. Kidney Care UK reports that around half of those with advanced kidney disease experience persistent itching, and it affects nearly all patients undergoing dialysis or conservative kidney failure treatment.

As kidney function worsens, itching often becomes more severe. Factors that can trigger or intensify symptoms include dry skin, heat, inadequate dialysis, and high calcium levels in the blood.

Additional signs of kidney disease may include:

Unexplained weight loss and poor appetite

Swelling in the feet, ankles, hands, or face due to fluid retention

Shortness of breath

Fatigue

Blood in the urine

Increased nighttime urination

Trouble sleeping

Muscle cramps

Nausea

Frequent headaches

Sexual dysfunction in men

If you experience persistent itching along with any of these symptoms, it’s important to speak with your GP for proper evaluation and care.
