Diabetic foot ulcers are a common and serious complication of diabetes, affecting up to 15% of diabetic patients during their lifetime. These ulcers form as a result of skin tissue breaking down and exposing the layers underneath. They are most often located on the bottom of the foot. Because many people with diabetes have reduced nerve sensation (neuropathy), foot injuries are frequently not painful and, thus, often go unnoticed until severe complications arise. Early identification and treatment are critical to preventing infections and more severe consequences, including amputation. This blog outlines how to identify diabetic foot ulcers and provides prevention tips to manage diabetes effectively.
1. Skin Changes
Overview: The first sign of a potential diabetic foot ulcer is a noticeable skin change on the feet, especially on the pressure points of the foot.
Signs to Watch For:
- Changes in skin color, becoming red or darker.
- New swelling, which could suggest inflammation or infection.
- Increased temperature around a specific area of the foot.
2. Calluses and Corns
Overview: Calluses and corns may seem benign but can indicate areas of high pressure or friction that are at high risk of breaking down into ulcers.
Signs to Watch For:
- Thickened skin areas, particularly if they are becoming larger or thicker rapidly.
- If a callus or corn starts to break down or bleed internally, it may appear as a discolored patch on the skin.
3. Open Sores
Overview: Open sores on the foot that do not heal or that heal very slowly are typical of diabetic foot ulcers.
Signs to Watch For:
- Any break in the skin that doesn’t start to heal within a week or two.
- Sores or wounds that drain fluid or pus, indicating possible infection.
4. Sensation Changes
Overview: Loss of sensation in the feet, a condition known as neuropathy, is a common cause of diabetic foot ulcers.
Signs to Watch For:
- Tingling, pain, or a complete lack of feeling in the foot.
- Check regularly by feeling your feet with your hands for hot or cold spots, which indicate abnormal blood flow.
5. Infection Signs
Overview: Infections are dangerous in diabetic individuals due to poor blood circulation that slows healing.
Signs to Watch For:
- Foul smell coming from an open wound.
- Redness, warmth, or swelling around the wound.
- Fever or chills may indicate that the infection has spread more systemically.
Prevention Tips
Regular Monitoring: Inspect your feet daily for any changes or injuries. Use a mirror to check the soles of your feet or ask for help if you are unable to see clearly.
Proper Footwear: Wear well-fitting, protective footwear at all times to prevent injuries. Avoid walking barefoot, even indoors.
Control Blood Sugar Levels: Good diabetes management is key to preventing foot complications. Keep your blood sugar within target ranges to help prevent nerve damage and promote good circulation.
Moisturize Your Feet: Dry skin can crack and allow germs to enter. Moisturize your feet regularly but avoid getting lotion between your toes.
See a Specialist Regularly: Regular check-ups with a healthcare provider or a specialist in diabetic foot care can help you manage your foot health proactively.
Conclusion
Recognizing the early signs of diabetic foot ulcers is crucial for preventing serious complications. If you notice any of the signs discussed, consult with a healthcare provider immediately. Timely and effective management can prevent infections and reduce the risk of amputation.
