Why Many Diabetic Patients Can’t Feel Foot Injuries
In my practice, I often see patients with diabetes who are surprised to discover cuts, blisters, or ulcers on their feet — sometimes after weeks have passed. They often ask, “Why didn’t I feel this?” This lack of sensation is usually due to a condition called diabetic neuropathy, which affects the nerves that carry pain and temperature signals.
1. What is Diabetic Neuropathy?
Diabetes can damage nerves over time, especially in the feet and lower legs. This nerve damage reduces the ability to feel pain, heat, or cold.
2. Why Foot Injuries Go Unnoticed
Because the nerves are less sensitive, small cuts, pressure sores, or burns may go unnoticed until they worsen. This is why diabetic patients have a higher risk of infections and ulcers.
3. Who is at Risk?
Patients with poorly controlled blood sugar, long-standing diabetes, or high blood pressure are more likely to develop nerve damage.
4. Preventing Foot Injuries
- Daily foot inspections
- Wearing proper footwear
- Keeping feet clean and dry
- Regular check-ups with a healthcare professional
5. When to Seek Medical Evaluation
Any redness, swelling, wound, or unusual callus should prompt immediate evaluation. Early care can prevent complications like infections or ulcers.
Doctor’s Insight
Numbness in the feet is a silent warning. As a doctor, I emphasize that regular self-examination and professional monitoring are key to protecting your mobility and overall health.
