Persistently high blood glucose can impair immune function, circulation, and tissue repair, while diabetic neuropathy can hide injuries and repeated pressure. Keeping glucose within the individualized range set by the diabetes clinician supports healing, but wound care, pressure relief, circulation assessment, and infection treatment remain essential.
Over time, diabetes can damage nerves and blood vessels. Reduced sensation may allow a blister, cut, or pressure point to worsen unnoticed, and reduced blood flow can limit oxygen and nutrients reaching tissue. High glucose is also associated with greater difficulty fighting infection.
Check glucose at the times directed, take medicines as prescribed, and share readings with the diabetes and wound teams. Do not change insulin or other diabetes medicines based on general wound advice. Illness, reduced food intake, steroids, and infection can alter glucose needs and may require clinician guidance.
People with diabetes should check the tops, soles, heels, and between toes for blisters, cuts, redness, swelling, drainage, and temperature or color change. Use a mirror or caregiver if needed. Do not walk barefoot, cut calluses yourself, or place heating pads on numb feet.
Continue the clinician's dressing, offloading, footwear, activity, and circulation plan. Adequate nutrition and smoking cessation also matter. A wound can worsen even when glucose readings look acceptable, so follow wound measurements and symptoms as well.
Report any new foot blister, cut, ulcer, color change, warmth, swelling, drainage, or black tissue promptly, even if it is painless. Contact the diabetes team for readings outside the action range they provided or sick-day concerns. Seek emergency care for severe weakness, confusion, vomiting with inability to keep fluids down, breathing difficulty, or signs of rapidly spreading infection.
