Persistent itching in your feet may be more than just a nuisance. While occasional irritation is common—caused by dry skin, insect bites, or cold weather—ongoing or intense itching could indicate an underlying health problem. Experts urge you to seek medical advice if symptoms persist, especially when accompanied by other warning signs.
According to Healthline, itchy feet may be linked to diabetes, kidney disease, or liver disorders. Here’s what to watch for.
Liver Disease
Liver disease, whether caused by fat buildup in the liver or excessive alcohol use, can become life-threatening if untreated. One key warning sign is persistent itching.
-
Where it appears: Usually on the arms, legs, palms, and soles of the feet.
-
What it feels like: From mild irritation to severe, exhausting discomfort.
-
Unique feature: Often occurs without a rash, unlike allergies or insect bites.
-
Triggers: Nighttime, warm environments, hot baths, or certain fabrics.
Liver-related itching is linked to bile salt buildup in the blood and changes in histamine, serotonin, hormones, and alkaline phosphatase.
Other symptoms to watch for:
-
Ongoing fatigue and weakness
-
Loss of appetite and unintentional weight loss
-
Reduced sex drive
-
Yellowing of the skin or eyes (jaundice)
-
Nausea or vomiting
Diabetes
Itchy feet, ankles, and legs can be an early sign of diabetes, especially when high blood sugar dries the skin or leads to complications like nerve damage or kidney problems.
Other warning signs include:
-
Excessive thirst
-
Frequent urination, especially at night
-
Extreme tiredness
-
Weight and muscle loss
-
Genital itching or recurring thrush
-
Blurred or impaired vision
Early detection and blood sugar management can prevent complications and reduce symptoms.
Kidney Disease
Persistent itching is common among people with advanced kidney disease. Kidney Care UK reports that around half of patients with severe kidney issues experience ongoing itching, and it affects nearly all dialysis patients.
Triggers or intensifiers: Dry skin, heat, inadequate dialysis, high blood calcium levels.
Additional signs of kidney disease:
-
Unexplained weight loss and poor appetite
-
Swelling in the feet, ankles, hands, or face
-
Shortness of breath and fatigue
-
Blood in the urine
-
Increased nighttime urination
-
Trouble sleeping and muscle cramps
-
Nausea, frequent headaches
-
Sexual dysfunction in men
When to Seek Medical Help
If you notice persistent itching in your feet accompanied by any of these symptoms, contact your GP for evaluation. Early detection can make a significant difference in managing these conditions effectively.
