Why is Foot Care Essential for Diabetes?

Healthful Vitality | 2/8/2025 | Why is Foot Care Essential for Diabetes?

Diabetes is a chronic condition that affects millions of people worldwide. While it is widely known for its impact on blood sugar levels, it can also lead to various complications, including nerve damage and poor blood circulation. These complications can significantly affect the feet, making foot care crucial for individuals with diabetes. In fact, about 1 in 5 people with diabetes who go to the hospital do so for foot problems ¹. This highlights the importance of understanding why foot care is so essential for individuals with diabetes. So, why is foot care essential for diabetes? Let’s explore.

The Link Between Diabetes and Foot Health

Diabetes can damage the nerves and blood vessels in the feet, leading to a condition called peripheral neuropathy. This nerve damage can cause numbness, tingling, pain, or a complete loss of feeling in the feet ². When you lose feeling in your feet, you may not notice injuries such as cuts, blisters, or sores, which can lead to serious infections ³.

In addition to nerve damage, diabetes also causes blood vessels to narrow and harden, resulting in poor circulation ⁴. This poor circulation makes it harder for wounds to heal and increases the risk of infection ². Even minor foot problems can quickly become serious in people with diabetes due to these complications.

Risk Factors for Diabetic Foot Problems

Anyone with diabetes can develop nerve damage, but certain factors increase the risk. These include:

• Blood sugar levels that are hard to manage: Consistently high blood sugar levels can damage nerves and blood vessels over time ⁵.
• Having diabetes for a long time: The longer a person has diabetes, the greater the risk of developing complications, especially if blood sugar levels are not well-controlled ⁵.
• Being overweight: Excess weight can put extra stress on the feet and contribute to poor circulation ⁵.
• Being older than 40 years: The risk of nerve damage increases with age ⁵.
• Having high blood pressure: High blood pressure can damage blood vessels and reduce blood flow to the feet ⁵.
• Having high cholesterol: High cholesterol can contribute to the narrowing of arteries, further impairing blood flow ⁵.

Potential Foot Complications for People with Diabetes

Several foot complications can arise from diabetes, and it’s crucial to understand that even seemingly minor issues can have serious consequences, including amputation, due to nerve damage and poor circulation ⁴. These complications include:

• Neuropathy: Nerve damage can cause numbness, tingling, pain, and loss of feeling in the feet, making it difficult to detect injuries ⁴. This loss of sensation means you may not feel a cut, blister, or even a small stone in your shoe, allowing these minor injuries to worsen and potentially become infected.
• Foot Ulcers: These are open sores that can develop due to nerve damage, poor circulation, or injury. Ulcers can become infected and, in severe cases, lead to amputation ⁵. Ulcers can be very painful and debilitating, limiting mobility and affecting quality of life.
• Infections: Due to reduced blood flow and impaired immune function, people with diabetes are more susceptible to foot infections ⁶. Infections can spread quickly and become life-threatening if not treated promptly. They can range from mild to severe, potentially leading to hospitalization or even amputation.
• Gangrene: This is a serious condition where body tissue dies due to a lack of blood flow. Gangrene often occurs in the feet and can necessitate amputation ⁶. It is a life-threatening condition that requires immediate medical attention.
• Charcot Foot: This condition involves changes in the shape of the foot due to nerve damage and weakened bones. It can cause deformities and increase the risk of ulcers and infections ⁶. Charcot foot can lead to significant changes in foot structure, making it difficult to find comfortable shoes and increasing the risk of further complications.

Daily Foot Care Guidelines for People with Diabetes

Daily foot care is essential to prevent complications and maintain healthy feet. Here are some guidelines to follow:

• Inspect your feet daily: Look for any cuts, sores, blisters, redness, swelling, or changes in the nails. Use a mirror to check the bottoms of your feet or ask someone for assistance ⁷.
• Wash your feet daily: Use warm water and mild soap. Avoid soaking your feet, as this can dry out the skin. Dry your feet thoroughly, especially between the toes ⁷.
• Moisturize your feet: Apply a moisturizer to the tops and bottoms of your feet, but avoid putting lotion between your toes, as this can lead to infection ⁸.
• Trim your toenails carefully: Cut your toenails straight across and file the edges to prevent ingrown toenails. If you have difficulty trimming your nails, consult a podiatrist ⁷.
• Wear appropriate footwear: Always wear shoes and socks, even indoors, to protect your feet from injury ⁷. Choose shoes that fit well and provide support.
• Protect your feet from extreme temperatures: Avoid exposing your feet to very hot or cold temperatures. Wear socks in cold weather and use sunscreen on your feet when exposed to the sun ⁸.
• Keep the blood flowing to your feet: Elevate your feet when sitting, wiggle your toes regularly, and don’t wear tight socks or stockings ⁸.
• Manage your blood sugar levels: Keeping your blood sugar levels within your target range is crucial for preventing nerve damage and promoting overall foot health ⁵. This is perhaps the most important step you can take to protect your feet. By managing your blood sugar effectively, you can slow the progression of nerve damage and reduce the risk of developing foot complications.
• Address excessive moisture: If you have excessive moisture between your toes, consider using methylated spirits to help keep the area dry and prevent fungal infections ⁹.

When to Seek Medical Attention

It’s important to seek medical attention promptly if you notice any of the following:

• Sores or cuts that don’t heal within a few days
• Redness, swelling, or warmth in your feet
• Pain or tenderness in your feet
• Changes in the color or temperature of your feet
• Ingrown toenails
• Corns or calluses with dried blood inside
• Any signs of infection, such as pus or a foul odor ²
• Loss of hair on your toes, feet, and lower legs ⁵
• Pain in your legs or cramping in your buttocks, thighs, or calves during physical activity ⁹

Research Overview

The information presented in this article is based on a comprehensive review of articles and medical websites discussing the link between diabetes and foot health. The research involved examining potential foot complications for people with diabetes, exploring guidelines for daily foot care, and identifying when to seek medical attention for foot concerns. Sources included the Centers for Disease Control and Prevention (CDC), the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the American Diabetes Association, and other reputable organizations ³.

Conclusion

Foot care is not just a matter of comfort; it’s a critical aspect of diabetes management. By taking proactive steps to care for your feet every day, you can significantly reduce your risk of developing serious complications and maintain a healthy, active lifestyle. Remember that early detection and treatment are vital for preventing long-term problems and maintaining a good quality of life.
