Many forms of severe stress and trauma, stroke, heart attack, and surgery can temporarily increase glucose levels.
Glycemia can also be increased by certain drugs such as antidepressants, corticosteroids, diuretics, estrogens, lithium, phenothiazine, phenytoin and Salicylic acids, or decreased by others, such as acetaminophen, alcohol, steroids, clofibrate, gemfibrozil.
However, the disease most directly associated to chronic increase of glycemia is diabetes mellitus, due to a decrease in the secretion of insulin, excess of its breakdown or decreased capacity of cells to transport it across its membranes (insulin resistance).
