Diabetic Foot: Signs and Symptoms
Foot problems are a common health concern for people with diabetes. They can happen when too much glucose or sugar in the blood damages the nerves in the feet. In certain instances, particularly severe ones, diabetic foot issues can lead to foot ulcers, infections, and potentially the amputation of the affected foot or a portion of the leg.
If you have diabetes, monitoring your feet regularly for any foot complications related to your condition is crucial. Here are the most common diabetic foot symptoms to watch out for.
Diabetic Foot Symptoms
Numbness in the feet
Numbness in the feet is the most common and earliest symptom of diabetic foot conditions. High blood sugar levels damaging the nerves can lead to a lack of sensation, making it difficult to feel pain from blisters, burns, cuts, sores, or other injuries.
Changes in skin colour and texture
If you have diabetic foot problems, discolourations may appear on your feet, either reddish, yellowish, or bluish. You might also notice the skin becoming very dry, with peels and cracks. This is caused by nerve damage that disrupts your body’s ability to control moisture in your feet.
Slow healing of wounds
If you have diabetes, you may notice that any cuts, sores, or blisters on your feet are slow to heal. This is because high blood sugar levels can restrict blood flow to the feet, making it challenging for the body to repair the wound effectively. If you observe that your wounds are not healing or are taking an unusually long time to heal, it is crucial to seek prompt medical attention to ensure proper treatment.
Swelling
Swelling, also known as oedema, is a common symptom experienced by people with diabetes. High blood sugar levels can damage blood vessels and impair circulation, especially to the extremities like the feet. This poor blood flow allows fluid to accumulate in the tissues, causing the feet to swell.
Pain
Nerve damage caused by high blood sugar levels can disrupt the normal signalling between the feet and the brain, resulting in painful sensations, including burning, tingling, or a feeling of pins and needles. This pain can be triggered by touch, movement, or even occur spontaneously. This can also be exacerbated by factors such as pressure from footwear or prolonged standing.
Abnormal changes in toenails
If you have a diabetic foot condition, you may experience changes in your toenails due to an increased susceptibility to fungal infections. Toenails may turn yellow, brown, or a darker shade. Alterations in the shape of toenails, such as becoming thicker, distorted, or developing ridges, can also be a sign of diabetic foot problems.
Being aware of the symptoms above enables you to take proactive measures to prevent diabetic foot complications. If you notice any of the symptoms discussed, seeking medical attention is necessary. Regular foot exams by a healthcare provider can help identify issues early and prevent them from escalating into more serious conditions.
