Some unexpected symptoms on your feet could be warning signs of a serious health condition related to blood sugar levels. Diabetes, a severe and often lifelong illness, leads to elevated blood sugar levels and affects over four million individuals in the UK.

As is the case with many health issues, early detection is crucial for timely treatment. While increased thirst and tiredness are common indicators, other less known symptoms can manifest in unlikely places, such as the feet. The Cleveland Clinic in the US cautions that foot issues are a red flag for diabetes.

“If you have diabetes, you’re at increased risk of foot conditions and complications, like open sores and infections,” they advise. Untreated, these conditions can become grave.

“If you develop foot issues, see your healthcare provider as soon as possible,” the clinic recommends. “Early treatment is key to preventing serious complications.”

Six foot-related symptoms of diabetes include:

• Cuts, ulcers, burns and blisters that don’t heal
• Dry, cracked skin
• Corns and calluses
• Fungal infections, like athlete’s foot and toenail fungus
• Ingrown toenails
• Hammertoes and bunions.

If you have poor circulation or neuropathy you are more likely to experience these foot complications. The clinic warns: “Diabetes-related neuropathy happens when you experience nerve damage due to persistently high blood sugar (hyperglycaemia).”

It notes that ulcers are among the most prevalent symptoms for diabetics, affecting about 15 percent of those with the condition. The clinic further explains: “The ulcers typically develop in areas where your foot repeatedly rubs or presses against shoes or other surfaces.”

It cautions that ulcers can lead to serious infections and, in some cases, may necessitate amputation of a foot or toe if the infection persists. The advice is clear: seek medical attention promptly if you notice any numbness, ingrown toenails, yellow nails, sores that won’t heal, pain, or cracked skin.

“It’s essential to get medical help for diabetes-related foot conditions. Don’t try to treat them yourself,” the clinic adds.

Additionally, the NHS highlights other diabetes symptoms to be vigilant about, including:
