Cortisol,growth hormone, adrenalin AKA epinephrine, glucagon, progesterone and thyroid hormone are considered counter-regulatory hormones as far as diabetes and blood glucose levels are concerned. They need just as much consideration as insulin, because changes in their bloodstream levels, can mean a possible interference with insulin, or a need for more of it. These changes can occur normally within the body to supply extra fuel when needed, or as symptoms of a disease state, or as a result of other medications, such as steroids.
