An uncomfortable and persistent itch on your legs, feet, or ankles could be a crucial warning sign of diabetes, a lifelong condition affecting millions across the United Kingdom. Health experts are urging the public to be aware of this common but often overlooked symptom, which signals that blood sugar levels may be dangerously high.
The Link Between Itchy Skin and High Blood Sugar
According to medical resources like Diabetes.co.uk, itchy skin is a common complication of both type 1 and type 2 diabetes. The sensation, which can range from mildly annoying to severely disruptive, often occurs on the lower limbs. It is thought that prolonged periods of elevated blood glucose (sugar) can directly cause the skin to become dry and itchy.
In some instances, the itch is not a direct result of high sugar but stems from other diabetes-related complications. Nerve damage (neuropathy) or kidney disease, both potential consequences of poorly managed diabetes, can also manifest as persistent itching in the feet, legs, or ankles. The good news is that treating the underlying cause—effectively managing blood sugar levels—can often alleviate or even eliminate the problem.
Expert Guidance on Diabetes and Skin Health
This advice is strongly supported by specialists at the renowned Cleveland Clinic. They state that approximately one in three people with diabetes will encounter a skin issue at some point, making dermatological symptoms a key area for vigilance.
"For people who don't have diabetes, a skin rash may be the first sign of high blood sugar or prediabetes," their guidance notes. This means an unexplained itch could be an early red flag, prompting a visit to a GP for checks that could prevent the onset of full diabetes. For those already diagnosed, a new or worsening rash might indicate that their current treatment plan needs adjusting to better control glucose levels.
Other Key Symptoms of Diabetes to Watch For
While itchy skin is a significant indicator, it rarely appears alone. The NHS lists several other common symptoms of diabetes that individuals should be aware of. If you experience the itch alongside any of the following, it is crucial to seek medical advice promptly:
- Feeling excessively tired or lacking energy.
- Urinating more frequently than usual, particularly at night.
- Experiencing constant and unquenchable thirst.
- Losing weight without trying or making any changes to your diet.
- Having blurred vision.
- Noticing that cuts or wounds take much longer to heal.
- Experiencing itching around the genitals or recurring bouts of thrush.
Diabetes is a serious, chronic condition, but early detection and management are vital. With over 5.8 million people in the UK estimated to be living with diabetes, recognising these signs—including that uncomfortable itch on your legs—could be the first step towards getting the necessary diagnosis and treatment. If you have concerns about any of these symptoms, you should speak to your GP without delay.
