Insulin: Major Causes Of Resistance And Why

Chronic Stress

Chronic stress is often a trigger for the development of insulin resistance. When an individual is under mental, physical, or emotional stress, the body responds by releasing stress hormones called adrenaline, norepinephrine, and cortisol. These stress hormones are released to prepare the body for a fight or flight response, increasing the demand on the body for energy. In order for the muscle cells to get this energy, a hormone called insulin has to be able to transfer glucose to the muscle cells. Some individuals produce insulin that does not perform this function well. Insulin resistance occurs when the cells do not necessitate the glucose or extra energy that floods into the individual's bloodstream every time stress hormones are released. This process means chronic stress causes glucose to build up in the blood, forcing the body to produce excessive amounts of insulin in response. As the cells become more resistant to the high levels of insulin, the pancreas becomes too tired out to modulate high blood sugar levels. Consistently elevated blood sugar causes the development of type 2 diabetes.
