Cracked heels may appear to be nothing more than a minor aesthetic concern, particularly during sandal season, but according to Niamh McMillan, pharmacy superintendent at Superdrug, they could actually signal undiagnosed diabetes.
Niamh has highlighted foot-related warning signs that mustn’t be overlooked, particularly if you haven’t undergone diabetes testing.
“Your feet can reveal a lot about your overall health, and there are several symptoms that might seem minor but could indicate something more serious,” Niamh explained.
“If you haven’t been tested for diabetes and are experiencing any of these signs, it’s worth speaking to a healthcare professional.”
Concealed foot-related warning signs that may indicate undiagnosed diabetes
Slow-healing wounds or sores
“If small cuts or sores on your feet aren’t healing within a few days, then this could be a red flag,” Niamh cautioned.
“Diabetes can reduce blood flow to the feet, which delays the healing process and can increase the risk of complications.”
Pins and needles, loss of sensation or burning feelings in the feet
“A frequent symptom of diabetes is peripheral neuropathy, nerve damage caused by high blood sugar levels. This can lead to tingling, numbness, or even a burning feeling in the feet,” Niamh outlined.
“It often goes unnoticed at first, but it’s one of the earliest signs of nerve damage and should always be discussed with a healthcare professional.”
Inflammation, redness or signs of infection
“Even mild inflammation around a crack or cut can quickly become serious for people with diabetes,” warned Niamh. “If you notice any redness, warmth, or swelling around a wound on the foot, seek medical advice immediately. Superdrug Online Doctor offers at-home diabetes test kits, while Superdrug high street health clinics offer a Diabetes Check Blood Test, £59, making it easy and accessible to get checked.”
Should you experience any of these symptoms, particularly if they’re accompanied by other indicators such as fatigue, excessive thirst, or frequent urination, it’s crucial to consult your pharmacist or GP for further medical advice.
