The presence of diabetes can contribute to a decreased wound healing rate. Increased glucose levels can stiffen the arteries and contribute to narrowing of the blood vessels. This can contribute to pressure injury development and is a risk factor for impaired wound healing.
Diabetes is an illness in which the individual’s blood glucose level is above the established range. Glucose is present in the foods we eat. Most foods contain a blend of carbohydrates, proteins, and fats. The amount of each of these nutrients in the foods we consume determines how quickly the body transforms food into glucose. For instance, consuming carbohydrates affects blood glucose levels one to two hours after the meal. Ingesting protein has very little influence on blood glucose levels, and the glucose from the fat in foods is slowly absorbed and does not contribute to increase glucose levels.
