Why are people with diabetes more prone to foot ulcers?

Diabetes increases foot ulcer risk through two key mechanisms: peripheral neuropathy (nerve damage) that reduces sensation so injuries go unnoticed; and impaired circulation that slows healing and reduces resistance to infection. Together, these mean that a minor injury — a blister, cut, or pressure sore — that would heal quickly in a non-diabetic person can develop into a serious ulcer. This is why regular foot inspection, well-fitting footwear, and proactive foot care are essential in diabetes management.

How important is blood sugar control for healing diabetic foot ulcers?

Optimal blood glucose control is fundamental to diabetic foot ulcer healing. Hyperglycaemia impairs white blood cell function, reduces collagen synthesis, and further compromises already impaired circulation — all of which dramatically slow wound healing and increase infection risk. Achieving and maintaining target glucose levels during wound healing is therefore a clinical priority and significantly affects outcomes. Nutritional support, activity levels, and stress management all influence glycaemic control alongside medication.

What complementary approaches may support diabetic foot care?

Nutritional optimisation is meaningful — adequate protein, zinc, vitamin C, and vitamin A support wound healing. Omega-3 fatty acids have anti-inflammatory and circulatory benefits. Hyperbaric oxygen therapy has evidence for promoting healing in resistant diabetic foot ulcers. Acupuncture may support peripheral circulation. However, diabetic foot ulcers require active medical wound care and monitoring — complementary approaches are adjuncts, not primary treatments, and should be coordinated with the treating medical team.

What preventive foot care habits matter most for people with diabetes?

Daily foot inspection (using a mirror for the soles if needed), wearing well-fitting footwear at all times, never walking barefoot, keeping feet clean and moisturised but avoiding cream between toes, trimming nails straight across, and attending regular podiatry appointments are the most important preventive practices. Any new blister, cut, redness, warmth, or wound — however small — should be assessed promptly rather than monitored at home.

Quick answer

Do any of these feel familiar?

Diabetic foot ulcers are most commonly experienced as open wounds on the feet that are slow or resistant to healing — typically arising in areas of reduced sensation due to peripheral neuropathy
Because nerve damage often means limited pain sensation in the affected foot, many people describe discovering an ulcer only when they notice a wound visually, smell an infection, or notice changes in the surrounding skin
Fear about the implications — potential infection, hospitalisation, or amputation — is a significant component of the experience
The intensive wound care required, combined with the need to offload pressure from the foot, can significantly restrict mobility and daily activities for extended periods
