Diabetic Foot Ulcers – Causes, Early Signs, Treatment & Prevention – By Dr. Balaraju Naidu, Robotic Orthopedic Surgeon, ONUS Robotic Hospitals
Diabetic Foot Ulcers (DFU) are one of the most severe and common complications of diabetes. Nearly 15% of diabetic patients develop a foot ulcer at some point, and delayed treatment significantly increases the risk of infection and amputation. The good news? Most diabetic foot ulcers are preventable with simple care, awareness, and regular medical checkups.
What Is a Diabetic Foot Ulcer?
A diabetic foot ulcer is an open wound that occurs due to nerve damage, poor circulation, and high blood sugar. Even small injuries — cuts, cracks, or blisters — can become deep ulcers that do not heal easily.
Why Do Diabetic Foot Ulcers Occur?
- Peripheral Neuropathy
High sugar damages nerves → reduced sensation → injuries go unnoticed. - Peripheral Arterial Disease
Blood vessels become narrow → poor healing. - Weakened Immunity
High glucose promotes bacteria growth → faster infection.
Early Warning Signs
Spotting early symptoms helps prevent serious complications. Look out for:
- Tingling or burning sensation
- Numbness
- Skin cracks
- Corns and calluses
- Red or dark patches
- Swelling
- Foul smell
- Slow-healing wounds
If a wound doesn’t heal in 48–72 hours, consult a specialist.
Complications if Ignored
Delaying treatment can lead to:
- Deep infection
- Cellulitis
- Bone infection (osteomyelitis)
- Gangrene
- Amputation
More than 85% of diabetes-related amputations start as minor ulcers.
