Health experts are urging people,especially those living with or at risk of Diabetes—to pay closer attention to changes in their feet, as these may signal underlying blood sugar problems.
Persistently high glucose levels can damage nerves and blood vessels over time, a complication known as Diabetic neuropathy, which often affects the legs and feet first.
Medical professionals say one of the earliest warning signs is numbness or tingling. This occurs when nerve damage reduces sensation, making it harder to feel pain, heat, or injuries. As a result, small cuts or blisters may go unnoticed and worsen over time.
Another serious concern is the development of foot ulcers. These are open sores, commonly found on the soles of the feet, that heal slowly due to poor blood circulation. If left untreated, they can lead to severe infections and complications.
Some individuals may also experience burning sensations or sharp pain in their feet, another effect of nerve damage. This discomfort can range from mild to severe and may worsen at night, affecting sleep and overall quality of life.
Fungal infections are also more common in people with high blood sugar. Conditions such as Athlete’s foot can cause itching, redness, and cracking of the skin, while nail fungus may lead to thick, brittle, or discoloured toenails. These infections thrive in warm, moist environments and can spread if not treated promptly.
In more severe cases, reduced blood flow can lead to Gangrene. This is a medical emergency that may require urgent treatment to prevent further complications, including possible amputation.
Changes in foot structure may also occur. Nerve damage can weaken the muscles in the feet, leading to deformities such as hammertoes or unusually high arches, which can further increase the risk of injury.
Doctors emphasise that regular foot care is essential for people with diabetes. Daily checks for cuts, swelling, or unusual changes, along with proper hygiene and well-fitting footwear, can help prevent complications. Most importantly, maintaining stable blood sugar levels remains the most effective way to protect foot health.
Early detection and proper care can significantly reduce the risk of serious outcomes, highlighting the importance of not ignoring even minor changes in the feet.
