Cortisol is a hormone that is essential to proper body function. It is produced by the adrenal cortex in the adrenal gland and is one of the primary factors in the body's stress response. So much so that it is often referred to as the stress hormone because it raises the blood pressure during times of stress.

Cortisol is often used in pharmaceuticals and certain drugs for allergies, inflammation and even arthritis. However, in this form it is called hydrocortisone.

There is no getting around the fact that the body needs cortisol in order to function properly. And there is quite a complex system in place in charge of regulating this substance. Basically, the hypothalamus releases CRH, which then triggers the pituitary gland to release ACTH. ACTH then encourages the adrenal cortex in the adrenal glands in the body to produce more cortisol. When you are highly stressed, pregnant, depressed, very athletic, an alcoholic or suffer from a panic disorder, you will have high levels of cortisol.

As you can see, it is all about balance when it comes to cortisol in the body. And when that balance is thrown off, serious problems can arise.

If you have too much cortisol you may end up with Cushing's Syndrome, which can manifest itself by means of obesity in the upper body and very thin limbs. Or, if you do not have enough cortisol, you may end up with Addison's Disease, a very serious condition caused most often by tumors on either the pituitary or adrenal glands.

Since cortisol is so important to your well being, it is vital you know where your body's levels stand. And with an at home testing kit you can easily detect your levels and put your mind at ease. Even those individuals that feel extremely healthy may not be on the inside, thus the importance of at home tests.
