It may seem odd, but some warning signs of a potentially dangerous blood sugar-related health condition could manifest on the feet. Diabetes is a severe and typically lifelong disease that results in excessively high blood sugar levels.

It affects over four million people in the UK, with health experts cautioning that even more individuals might be unknowingly living with the condition. As with any medical problem, the earlier you identify the symptoms, the sooner you can receive the necessary treatment.

Some of these indicators are fairly well-known, such as increased thirst and fatigue. However, others are less so and can appear in some unexpected places.

The Cleveland Clinic, based in the US, cautions that some diabetes warning signs can show up on the feet. “If you have diabetes, you’re at increased risk of foot conditions and complications, like open sores and infections,” it explains.

If left untreated, these can become serious, the clinic warns. “If you develop foot issues, see your healthcare provider as soon as possible,” it advises. “Early treatment is key to preventing serious complications.”

Examples of foot and toe conditions associated with diabetes include: People are most at risk of foot conditions and complications if they have poor circulation or diabetes-related neuropathy. The clinic states: “Diabetes-related neuropathy occurs when you experience nerve damage due to persistently high blood sugar (hyperglycemia).”

Ulcers are a prevalent issue for those with diabetes, affecting about 15 percent of patients. The clinic warns: “The ulcers typically develop in areas where your foot repeatedly rubs or presses against shoes or other surfaces.”

It further cautions that “Ulcers can lead to infections. Sometimes, the infection doesn’t go away, and you may need to have part of your foot or toe surgically removed (amputated).”

The advice is clear: see a doctor immediately 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 advises. Additionally, the NHS points out other symptoms of diabetes to be vigilant about.
