Some early signs of diabetic foot disease include a decrease in skin temperature of both feet, such as constantly feeling coldness in the feet, which indicates insufficient blood supply. Another symptom is peripheral neuropathy, which manifests as numbness or burning in both feet, and unusual sensations like stepping on cotton or feeling like ants are crawling. These are also early signs of diabetic foot disease. Once there is a break in the skin surface, it is crucial to be vigilant as it might be diabetic foot disease. Diabetic foot disease is a very serious condition and one must take early preventive measures. At the slightest sign of any skin break, it is essential to seek proper treatment at a standard hospital.

What are the symptoms of diabetic foot infection?

Symptoms of diabetic foot infections can include localized gradual wound ulceration, suppuration, and odor. In severe cases, patients may observe necrosis of the foot with a dark color. Some patients may experience systemic effects, including fever. Therefore, the progression of diabetic foot can be rapid. It is recommended that diabetic patients seek medical attention promptly when they notice any wound ulceration to prevent worsening of the infection.

Can diabetic foot be cured?

Diabetes has many complications, and once detected, the complications of diabetes cannot be completely cured. Diabetic foot is a relatively serious complication of diabetes. Diabetic foot generally involves many years of underlying vascular and nerve damage that eventually leads to infection or ulceration, resulting in the final formation of diabetic foot. Whether such a serious complication can be cured actually depends on the duration of the patient’s condition, the extent of the lesion, and most importantly, how soon they seek medical attention. For instance, if the infection is very severe, has damaged the bone, or if there is dry gangrene with local tissue necrosis in the foot, then no matter what conservative treatment is applied, it will not be effective, and surgical amputation will be the only option, meaning the foot cannot be saved. However, if some individuals only have early-stage skin ulceration that cannot heal, or if there is an infection that is not very severe, and they seek medical attention early, controlling the infection and treating with nerve nutrition and vascular protection can actually heal the ulcerated area of the foot.

What to eat for diabetic foot?

Typically, patients with diabetic foot have had diabetes for a long period, and often have diabetic nephropathy, or serious hypoproteinemia and malnutrition. In such cases, patients with diabetic foot need to supplement with protein, specifically high-quality protein, and must avoid low-quality protein. What constitutes low-quality protein? This includes soy products and plant proteins. High-quality protein, on the other hand, includes sources like milk, eggs, poultry, and meat. However, if renal insufficiency is present and creatinine levels have increased, the amount of protein must be limited. Protein intake should be calculated based on body weight and creatinine levels, using different coefficients to determine the total daily protein allowance. It is crucial to make these protein adjustments within the framework of a diabetic diet.

Is it good for people with diabetes to soak their feet?

Whether soaking the feet is beneficial for diabetic foot or not first depends on whether there are any wounds on the feet. If it is a grade 0 diabetic foot, where the diabetic only experiences abnormal sensations, numbness, or pain in the foot without any wound, then soaking the feet is permissible. However, it is crucial to be mindful of the water temperature during soaking; it generally should not exceed 40°C to avoid burns. If the diabetic foot has open wounds, foot soaking is not recommended. Soaking feet with wounds can easily lead to increased infection of the wounds.

Where does diabetic foot hurt?

Diabetic foot primarily involves changes in the blood vessels and nerves of the lower limbs and feet, so early symptoms may include numbness, a feeling of stepping on cotton, and weakness in the legs. Furthermore, pain can manifest as numbness and pain in both soles of the feet, or as vascular and neurological pain in the lower limbs and the inner thighs. If diabetic foot is accompanied by venous thrombosis in the lower limbs or arterial embolism, the resulting pain can affect the entire lower limbs symmetrically and present as intermittent claudication. Therefore, the main sites of pain in diabetic foot are determined by the locations of vascular and nerve damage.
