Diabetic Foot Ulcers

  1. Patients tend not to initially feel them and this allows the ulcer to grow (wider and deeper rather than the ulcer actually “growing”) and become complicated
  2. If you had no issues then a cut is usually sore and the body has a really good way of treating them. However a diabetic usually has complications that tend to reduce healing
  3. Diabetics have a normal reduced immunity
  4. In some cases the circulation is poor to allow adequate healing/getting antibiotics to the area
  5. Any ulcer can be quick to heal or take a really long time (years with some leg ulcers)
  6. Even when the ulcer is healed it will take 2 years to heal the underlying structures. That means that area is fragile for a long period of time and the occurrence of another ulcer on the same site is quite high.
  7. The foot is a complicated place to have an ulcer because you need your feet to walk- so any dressing under the foot tends to get squished out. Any rubbing or pressure areas (most of the underside of the foot) will add to reduced circulation. The foot is far away from everything and has small blood vessels going to the toes which can become complicated
  8.  Foot ulcers especially can go from healing to bad in a very short space of time
  9. Bad blood sugar control reduces healing. Infection can also raise blood sugars- as well as stress.
