Easy Tips to Prevent and Treat Diabetic Foot Diseases and Ulcers: World Diabetes Day 2024

World Diabetes Day, celebrated on November 14 each year, aims to raise awareness about diabetes as a global health issue. One of the most common and serious complications of diabetes is diabetic foot ulcers (DFU), also known as Diabetic Foot Disease (DFD) or Diabetic Foot Syndrome (DFS). These ulcers are typically caused by neuropathy, a nerve-related condition due to diabetes. They form when skin tissue breaks down, often in areas where pressure is exerted on the foot, such as under the big toe and heel. Although not everyone with diabetes develops foot ulcers, poor foot hygiene and care can significantly increase the risk. Early intervention and proper foot care are essential for preventing this condition.

Causes and Risk Factors of Diabetic Foot Ulcers

Diabetic foot ulcers are caused by several factors that disrupt the normal function and healing of the skin on the feet. Key contributors include nerve damage (neuropathy), poor blood circulation (vascular issues), and high blood sugar levels. Neuropathy can lead to loss of sensation in the feet, increasing the likelihood of unnoticed injuries and wounds. Poor circulation reduces blood flow to the feet, slowing down healing. High glucose levels further delay wound healing, and an untreated wound may eventually become infected. Other risk factors include ill-fitting shoes, improper toenail grooming, obesity, smoking, and poor foot hygiene. Older men are particularly at risk, with the majority of foot ulcers occurring in this demographic.

Early Signs and Symptoms of Diabetic Foot Disease

Recognizing the early signs of diabetic foot disease is crucial for preventing severe complications. Symptoms to watch for include persistent swelling in the feet or ankles, changes in skin color (such as redness, discoloration, or a bluish tint), slow-healing wounds or cuts, numbness or tingling sensations, and foul odors from the feet, which could indicate an infection. Dr. Rajeev Singh emphasizes the importance of early detection and treatment to avoid serious complications, such as infections that can lead to amputation.

Diagnosis and Treatment of Diabetic Foot Ulcers

Diagnosing diabetic foot ulcers typically involves a physical examination by a healthcare provider, who will look for signs such as drainage or a noticeable lump on the affected area. The severity of the ulcer is often assessed using the Wagner Ulcer Classification System. Treatment may include “off-loading” (avoiding pressure on the ulcer), wearing specially designed footwear, or using a cast or brace. In some cases, the ulcer may need to be cleaned or debrided to remove dead tissue. X-rays and blood tests may be performed to assess bone involvement or infection.

Managing Diabetic Foot Disease: Expert Recommendations

Managing diabetic foot disease requires a proactive approach and regular care. Dr. Rajeev Singh offers several strategies for effective management, such as performing daily foot checks for cuts or blisters, wearing well-fitted shoes to prevent friction, and maintaining blood sugar control to avoid nerve and vascular damage. Regular low-impact exercises like walking or swimming can help improve circulation. It is also important to maintain foot hygiene by washing and moisturizing feet daily, avoiding the spaces between the toes to prevent fungal infections. Regular medical check-ups with a podiatrist are essential for professional advice and assessments.

Prevention of Diabetic Foot Ulcers

Preventing diabetic foot ulcers from progressing requires early intervention and consistent care. The importance of visiting a doctor at the first sign of infection or a foot wound. Keeping blood sugar levels under control is a key factor in reducing the risk of complications. Good foot hygiene is essential, including washing and moisturizing the feet daily, trimming toenails properly, and drying the feet thoroughly. Wearing well-fitting shoes that provide support and visiting a podiatrist regularly for callus and corn removal can further prevent ulcers. Regular foot care and timely medical intervention significantly reduce the likelihood of infections and complications from diabetic foot ulcers.
