As the number of diabetic patients increases, the incidence of diabetic foot also rises. Currently, the prevalence of diabetic foot in China is 5.7%, which is below the global average. Diabetic foot primarily occurs in patients who have had diabetes for over ten years, often due to poor blood sugar control and inadequate care. Diabetic foot is also one of the three major non-traumatic causes of amputation. Therefore, the most severe consequence of diabetic foot is amputation.

Where does diabetic foot hurt?

Diabetic foot refers to those with a history of diabetes who subsequently develop skin ulceration and pus formation on the feet, which can progress to localized gangrene or gangrene of the entire foot. This condition is then termed as diabetic foot. It is usually due to three factors: The first is vascular factors, often accompanied by arterial narrowing in both lower limbs, leading to ischemia and hypoxia. The second is neurological factors, typically accompanied by peripheral neuropathy, causing numbness in both feet and insensitivity to pain, thus often pain is not felt. The third factor involves the presence of an infection. These three factors together make it easy for diabetic foot to develop. Therefore, most patients with diabetic foot do not feel pain. However, if the neuropathy is relatively mild or is a painful neuropathy, these patients may feel pain in their feet or at the site of skin ulceration.

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

Diabetic foot is primarily classified into a level 0 diabetic foot and levels 1 to 5 diabetic foot. If it is a level 0 diabetic foot and the patient does not have any wounds, then soaking the feet is permissible. Level 0 diabetic foot mainly refers to a high-risk diabetic foot, in which case soaking is allowed. However, care must be taken to ensure that the water temperature is not too high to avoid scalding the skin. If the diabetic foot has reached levels 1 to 5, where the patient has wounds and ulcerations, soaking the feet is not recommended, as it can easily worsen and exacerbate the wound ulcerations. Therefore, people with diabetes should consider their individual conditions to determine whether foot soaking is suitable.

Care of diabetic foot wounds

In terms of caring for diabetic foot wounds, medical treatment, surgical intervention, or debridement is of course necessary. Regarding foot care, it's important to examine the condition of the wound. The primary principle is first, in dietary care, to ensure a high protein diet under the allowance of liver and kidney functions, and then a low-fat diet. It's important to include high-quality protein, which is beneficial for wound healing. Locally, the wound area must be kept clean and dry. It is crucial to maintain a concept of sterility, avoiding actions like breathing over the wound with the mouth or touching the wound area with hands. The wound should be cleaned or locally disinfected regularly every day. Additionally, foot wounds in diabetics should slightly elevate the feet to facilitate blood return. Moreover, regular observations of changes in the wound should be made and communicated timely to the doctors at the 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.

What to eat for diabetic foot

The treatment of diabetic foot begins with good blood sugar control. Therefore, dietary control is necessary for diabetic foot. For diabetic patients, it is required to eat three meals a day at regular times and avoid multiple smaller meals or snacks. Foods such as fruits, nuts, and those high in fats should be eaten less frequently. Additionally, liquid foods like soups and porridges should also be reduced. Only when blood sugar is well-controlled can the treatment of diabetic foot be effective.
