Diabetic patient fell asleep with foot in a heating register and burned foot without realizing!!
People with diabetes are at high risk of foot injuries and even gangrene (commonly the dry form without pus) due to a combination of both neuropathy and angiopathy.
The fact that high blood sugar levels damages the nerves (neuropathy), particularly those of the feet, makes it easier for a patient to injure himself without realizing because sensation is lost. It also damages blood vessels (angiopathy), restricting the blood supply to the feet, tissues are deprived of oxygen, thus causing the cells to die leading to gangrene. The poor circulation to the area leads to decreased white blood cells (the infection-fighting cells) reaching to the area and infection can develop.
The ischemic and neuropathic dystrophic tissue is vulnerable to infections and injuries along with delayed wound healing. Triggering factors are often banal skin injuries from footwear or concussion damage. The same counts for usually harmless skin damages from walking barefoot or cutting nails. Especially older people with reduced vision and/or retinopathy are at risk.
