Doctor alert: If you have itching in these 3 areas, your life expectancy will be short. (

In some advanced cases of diabetes, nerve damage, called diabetic neuropathy, causes deep and persistent itching. This itching is not merely superficial; it results from nerve dysfunction, preventing proper communication with the brain. Repeated scratching damages the skin, increasing the risk of infection. Without treatment, this can lead to serious complications, such as ulcers or even amputations in extreme cases.
Biliary cirrhosis: intense nighttime itching

Another cause of persistent itching of the hands and feet is biliary cirrhosis, a little-known but serious liver disease. This condition, which primarily affects the bile ducts of the liver, causes a buildup of bile, leading to progressive liver damage. The itching caused by biliary cirrhosis is often more intense at night and can become unbearable for those affected. In addition to itching, biliary cirrhosis can manifest with other symptoms such as extreme fatigue, dark urine, dry mouth and eyes, and digestive discomfort.

This type of cirrhosis progresses slowly, and its early signs are often ignored or attributed to simple skin irritations. However, prompt attention and medical monitoring are essential to prevent irreversible liver failure.
