Cortisol Effects on Insulin

Cortisol is a hormonal steroid that occurs naturally in the body. The adrenal system creates cortisol in response to stress, and the hormone controls the way the body converts sugar into energy, thereby affecting insulin levels.

Function

• When under stress, cortisol is produced to provide a surge of energy, making it easier to flee or fight harm and increasing pain tolerance. Cortisol regulates insulin and blood pressure, when released in appropriate amounts.

Effects

• A person suffering chronic stress will have consistently high cortisol levels. A diet high in sugary, starchy foods can exhaust the adrenal system and cause cortisol levels to be too low. Both can cause insulin resistance.

Considerations

• Insulin resistance can bring on many illnesses, including pre-diabetes, type II diabetes, metabolic syndrome, poly cystic ovarian syndrome and Cushing's Disease.

Misconceptions

• Because exercise does cause stress to the body, many believe it will adversely increase cortisol levels. However, because it increases metabolism, relieves anxiety and improves sleep patterns, exercise is actually an effective way to lower cortisol.

Prevention/Solution

• Several factors, including frequent exercise, stress management, a consistent sleep schedule and a diet filled with foods low in fat and high in fiber will support healthy cortisol levels.
