DFU Manual - Episode 1 - Intro
healtheducation
A diabetic foot wound you can't feel can cost you a limb — here's how the damage chain works and how to break it.
Episode 1 of the DFU Manual opens with the hidden danger behind diabetic foot ulcer disease: a wound you cannot feel. Diabetes dulls the nerves in the feet, so an injury can start without pain to warn you — which is exactly what makes it both serious and preventable.
The scale, per Dr. David Armstrong, is hard to ignore:
- A new diabetic foot ulcer appears somewhere in the world every 1.2 seconds.
- A limb is lost to a diabetes-related amputation every 20 seconds.
- Roughly 85% of those amputations are preventable with early detection and care.
The chain of damage
Three starting points feed into the same path: nerve damage (neuropathy), an everyday trauma, and poor circulation from vascular disease. From there the chain runs sore → infection → amputation, and it can be broken at any step:
- Nerve damage — high glucose dulls sensation, so pain, heat, and pressure go unnoticed.
- Silent wound — an unfelt injury becomes a sore no one sees.
- Infection — poor circulation lets bacteria spread deep and fast.
- Amputation — untreated tissue dies, and the limb, or life, is at risk.
You are the captain
Saving feet takes a team — doctors, nurses, podiatrists, and surgeons — but the patient leads. Daily foot checks, the right footwear, and regular visits move you into the preventable 85%. Clinicians supporting these patients can see how structured diabetic foot care and healing analytics help catch the chain early.
