How effective is wound care and dressing for diabetic foot ulcer?

A diabetic foot ulcer is an open area that may heal slowly when sensation, blood flow or glucose control is affected. Cleansing and a suitable dressing manage drainage, protect new tissue and reduce friction from footwear. The dressing does not remove pressure from the ulcer, restore circulation or treat an infection. A foot-care team may need to remove unhealthy tissue, choose offloading footwear, assess pulses and sensation, and review the wound regularly. Avoid judging progress by pain alone because reduced sensation can make a worsening ulcer feel less painful.

Follow the dressing plan given by your clinician and wash your hands before and after changing it. Do not soak the foot, walk barefoot or apply creams, powders or strong antiseptics unless advised. Keep weight and pressure off the ulcer using the recommended footwear or device. Inspect both feet every day, including between the toes, with a mirror or help from another person if needed. Keep diabetes medicines and meals consistent with your care plan, and bring the dressing or wound concerns to review rather than trimming tissue yourself.

Contact your diabetes or wound-care team promptly if the ulcer enlarges, becomes deeper, drains more, smells different or develops new surrounding redness, warmth or swelling. Seek urgent help for fever, chills, confusion, severe weakness, black or grey tissue, sudden colour change, a cold foot or rapidly spreading redness. New swelling or a break in the skin deserves attention even when there is little pain.

Ask how often the wound needs review, which dressing is appropriate, how to offload pressure and whether circulation or infection needs assessment. Ask which changes mean you should call the team the same day.
