What is Cortisol?

The adrenal glands are responsible for cortisol, one of the most important steroid hormones for the body. While it helps regulate metabolism, blood pressure, and inflammation, it is often referred to as the stress hormone due to its primary trigger. Its secretion increases while the body is under stress, and so do the energy levels, focus, and attention span. Non-essential body functions such as digestion and immune responses are also suppressed.

Having cortisol in the blood stream results in a short-term positive reaction, however, when cortisol is constantly elevated, that is when problems begin to arise. High amounts of cortisol can lead to negative health effects over time, even though it is important for survival. The constant state of stress, unhealthy diets, and restlessness increase cortisol production and result in fatigue, anxiety, excess weight, and Hypertension.

How to Test for High Cortisol Levels?

b) Saliva Test: Those suffering from conditions like Cushing’s syndrome where they have higher levels of nightly cortisol are diagnosed with this test. Saliva samples are collected during the later hours of the day when cortisol is at its lowest.

c) Urine Test (24-hour Urinary Free Cortisol Test): The collection of 24-hour urine samples helps calculate the total amount of cortisol produced in a day. This measurement is helpful for identifying constant elevated levels of cortisol over long time durations.

d) Dexamethasone Suppression Test: A blood sample is taken in the morning after patients take a synthetic steroid called dexamethasone at night.
