Diabetic ulcers are chronic, complex, or problem wounds of the legs and feet in people with diabetes.

Diabetic ulcers require a healthy, oxygenated wound bed to heal. A lack of sufficient oxygen (hypoxia) in the wound bed slows or stops the normal healing process and can lead to amputation.

HBOT helps repair wounds and enhance healing by improving blood circulation, encouraging the formation of new capillary blood vessels (angiogenesis) and supplying more oxygen to tissue in the wound bed. Hyperbaric oxygen also helps kill the anaerobic bacteria that cause some of the worst infections in chronic diabetic wounds.
