What is the first treatment for a diabetic foot ulcer?

A clinician checks the ulcer’s depth, surrounding skin, circulation and sensation. The wound may be cleaned and covered with a suitable dressing. Reducing pressure on the area is central because walking on an injured part of the foot can delay healing. Footwear, an offloading device or changes to activity may be recommended.

The clinician also looks for infection, damaged tissue and signs that the ulcer reaches deeper structures. Diabetes management, hydration and nutrition can affect wound recovery, so the wider health picture is considered alongside the dressing.

Arrange a prompt GP or wound-clinic assessment, even if the ulcer seems small. Keep the dressing clean and dry, follow the agreed dressing plan, and avoid walking barefoot. Do not cut away hard skin, use household antiseptics or apply a corn remedy unless a clinician has advised it. Check both feet daily for new redness, swelling, blisters, discharge or colour change.

Ask whether you need a pressure-relieving shoe or temporary reduction in walking. Take your diabetes medicines as prescribed and bring a list of medicines to the appointment. Wound care and dressing support can help with safe cleaning and covering.

Seek urgent medical care for spreading redness, increasing warmth or swelling, pus, a new unpleasant smell, fever, chills, severe pain or rapidly changing skin colour. Urgent assessment is also needed if the foot becomes cold, pale, blue or numb, or if you feel suddenly unwell. Diabetes can reduce pain sensation, so a painless change still deserves attention.

Ask how deep the ulcer is, how to keep pressure off it, which dressing to use, and what changes should prompt same-day review. You can also ask how often the wound needs checking and whether your footwear or diabetes plan needs adjustment.
