Diabetic foot: diagnosis, complications, and prevention

Understanding Diabetic Foot

Diabetic foot is a serious complication of diabetes mellitus, characterized by damage to the nerves and blood vessels in the lower limbs. Patients with diabetic foot are at risk of developing ulcers and infections, which can lead to limb amputation. Understanding this condition includes awareness of the importance of prevention and regular medical monitoring to timely identify signs of possible complications and prevent their progression.

Etiology of diabetic foot

Diabetic foot is a complication of diabetes caused by chronic metabolic disorders. It manifests in the degeneration of nerves and blood vessels, leading to tissue damage and the development of ulcers and infections. The main causes of diabetic foot development are prolonged high blood sugar levels (hyperglycemia), arterial hypertension, circulatory disorders, and degenerative changes in the peripheral nerves.

  • Hyperglycemia: Elevated blood glucose levels can lead to damage to blood vessels and nerves, contributing to the development of diabetic foot.
  • Arterial hypertension: High blood pressure can impair blood flow to the extremities, increasing the risk of ulcers and infections.
  • Nerve degeneration: Damage to peripheral nerves in diabetics can lead to loss of sensitivity in the legs, promoting the formation of sores and ulcers.
  • Ischemia: Insufficient blood supply to certain areas of the legs contributes to ulcer formation and slows down the healing process of tissues.
  • Microangiopathy: Small blood vessels in the legs can become less durable and prone to damage due to prolonged poor control of blood sugar levels.

The manifestation of signs of diabetic foot

Diabetic foot is characterized by various clinical manifestations, including the formation of ulcers, gangrene, foot deformities, redness or swelling, as well as loss of sensation or pain in the legs. Patients may experience symptoms such as numbness, tingling, or burning in the legs, indicating possible damage to the peripheral nervous system.

It is important to pay attention to even minor changes in the feet in diabetes, as diabetic foot is a serious complication associated with the risk of infections, amputations, and even death. Early detection and effective management of diabetic foot symptoms play a key role in preventing serious consequences of this disease.

  • Formation of ulcers: Diabetic foot often manifests as skin vulnerability on the feet, which can lead to the formation of ulcers due to pressure or injury.
  • Gangrene: In advanced cases of diabetic foot, gangrene may develop, requiring urgent intervention and posing a risk of amputation.
  • Foot deformities: Prolonged exposure to diabetes affects the nerves and vessels of the feet, potentially leading to deformities that increase the risk of injuries.
  • Loss of sensitivity: Uncontrolled blood glucose levels can cause nerve degeneration, leading to loss of sensitivity and an increased risk of injuries and infections.
  • Skin changes: External signs of diabetic foot may include changes in the color, texture, temperature of the skin, and the appearance of swelling, indicating disturbances in blood supply and nerve innervation.

Approaches to the treatment of diabetic foot: expert opinions

Experts in the field of medicine emphasize the importance of a comprehensive approach to treating diabetic foot, which includes controlling blood glucose levels, caring for damaged tissues, preventing infections, normalizing blood circulation, and regular monitoring of foot conditions in patients with diabetes. The main methods for treating diabetic foot include prescribing medications to control diabetes, surgical intervention in cases of gangrene or extensive ulcers, application of specialized wound treatments, and foot care.

Experts believe that early consultation with a specialist and timely initiation of diabetic foot treatment help prevent complications and reduce the risk of limb amputation. An individual approach to each patient, considering the specifics of their condition and appropriately selected therapeutic solutions play a crucial role in effective treatment and management of this pathology.

Procedure for diagnosing diabetic foot

Diagnosis of diabetic foot usually includes a visual inspection, assessment of foot and lower limb sensitivity, measurement of blood pressure in the foot area, as well as additional studies such as duplex scanning of blood vessels or X-rays to assess the condition of bones and joints. Laboratory tests may include checking blood glucose levels and culturing infected ulcers to identify the type of pathogen and the correct treatment.

Effective diagnosis of diabetic foot allows for early detection of complications and the establishment of necessary treatment to prevent serious consequences. An integrated approach, involving a comprehensive study of symptoms, laboratory research, visual examination, and the use of modern diagnostic methods, plays a key role in managing diabetic foot.

  • Visual inspection: The doctor examines the patient’s feet and lower extremities for wounds, ulcers, deformities, or signs of infection.
  • Sensitivity assessment: A check of the sensitivity in the feet and toes is conducted to identify any loss of pain or sensation.
  • Blood pressure measurement: The level of blood pressure in the feet area is determined to assess blood supply and circulation.
  • Additional studies: These may include duplex ultrasound of the vessels, X-rays, computed tomography, or magnetic resonance imaging for further evaluation of the condition of the tissues and vessels.
  • Laboratory tests: Include checking blood glucose levels, analyzing infected ulcers to identify types of pathogens and conducting antibiotic therapy.

Methods of therapy for diabetic foot

The treatment of diabetic foot involves a multifaceted approach aimed at controlling blood glucose levels, improving circulation, and restoring damaged tissues. Effective diabetes management, as well as regular inspection and care of the feet, play an important role in preventing complications and the development of ulcers and infections.

Methods of diabetic foot therapy include the use of medications to control infection, wound healing ointments and ulcer care, as well as physiotherapeutic procedures, surgical interventions when necessary, and specialized rehabilitation. The combined effort of physicians from various specialties, including endocrinologists, surgeons, dermatologists, and therapists, is essential for the effective treatment of diabetic foot and the prevention of its complications.

  • Glucose level control: Regular measurement of blood sugar levels and adherence to a diet help manage diabetes, preventing sharp changes in glucose levels.
  • Wound care: Cleaning and disinfecting wounds help prevent infections and promote effective healing.
  • Medication therapy: Use of antibiotics to combat infections, as well as the use of medications to improve circulation and pain relief.
  • Physical therapy: Use of physical procedures, massage, or exercises to improve circulation and restore the functions of damaged tissues.
  • Surgical intervention: In cases of severe deformities, ulcers, as well as when reconstruction of blood vessels or removal of damaged tissues is necessary, surgical treatment is required.

Measures for the prevention of diabetic foot

The prevention of diabetic foot involves a wide range of measures aimed at ensuring control of blood glucose levels, maintaining the health of blood vessels and nerves in the extremities, as well as regular foot care. An important part of prevention is adhering to a diet, engaging in physical activity, taking medications as prescribed by a doctor, and regularly visiting healthcare professionals for health monitoring.

Proper foot care is also important, including regular washing and drying, nail care, using comfortable and well-fitting shoes, and avoiding injuries and burns. Following specialists’ recommendations, being aware of one’s health condition, and seeking medical help in a timely manner can significantly reduce the risk of developing diabetic foot and its complications.

  • Blood glucose norm compliance: maintaining a stable glucose level reduces the risk of nerve and vessel damage.
  • Regular physical exercise: physical activity improves circulation and helps control glucose levels.
  • Healthy eating: a balanced diet low in sugar and rich in nutrients helps maintain foot health.
  • Foot care: regular washing, drying, moisturizing, and inspecting of feet help prevent the development of ulcers and infections.
  • Avoiding injuries: inspecting shoes before wearing, wearing protective footwear, and being cautious with sharp objects help prevent traumatic injuries.

Unusual aspects of diabetic foot

Diabetic foot can have unusual aspects, such as the occurrence of pain in the legs despite nerve damage and a loss of sensitivity, which is related to complex mechanisms including changes in pain perception in the body with diabetes. Another interesting fact is that compression therapies, such as stockings or graduated compression socks, can help improve circulation and reduce the risk of ulcers in patients with diabetic foot.
