Yes. Diabetics are more susceptible to cellulitis for several reasons. First, diabetic nerve damage can decrease sensation, especially over the lower extremities, leading to ulcers where cellulitis can develop. Often, diabetics also have poor circulation, which can lead to breakdown of tissue and impaired healing, and the high blood sugar provides a perfect environment for bacteria to grow.
Many reasons. A few ways to think about this. Diabetes compromises circulation, so if there is a site of injury/infection and the circulation there is poor, it will have a problem healing on its own. Bacteria love it, and cause cellulitis diabetes compromises nerves and sensations. Simple cuts and scrapes get missed and simple skin infections get caught much later.
