Diabetes & Immunity

How high blood sugar weakens your defenses.

Prolonged high blood sugar levels, known as hyperglycemia, can interfere with the normal functioning of immune cells. It impairs the ability of white blood cells, which are crucial for fighting infections, to function effectively.

High blood sugar can hinder the movement and function of immune cells, including neutrophils and macrophages, which are responsible for identifying and destroying invading pathogens.

Elevated blood sugar levels can slow down the healing of wounds and impair the body's defense against infection in open sores or cuts.
