Cortisol 101

on March 10, 2012

Hiya!  It’s still such a beautiful day!  I just got back from my friend’s wedding and on my way home I saw this huge garage sale.  Do you like garage/yard sales?   I went and picked my dad up and we went back to the sale.  I didn’t find anything, but my dad did.  What’s wrong with that picture?? 🙂

Anyway, I met a little friend while I was there.


Her name was Roxy..:)

Cortisol-Stress-and You:

On my way home from the wedding I was listening the KLOVE and they were talking about the connection between Cortisol and weight.  So I wanted to find some info on what that means for people who struggle with their weight and stress.

Cortisol is a steroid hormone produced in the cortex of the adrenal glands. Cortisol assists you in regulating blood pressure, cardiovascular functions, and your body’s use of fats, proteins and carbohydrates. Cortisol is also involved in glucose metabolism, insulin release for blood sugar maintenance, and inflammatory response. Cortisol helps in responding to and coping with stress, trauma and environmental extremes. Normal levels of cortisol increases energy and metabolism and helps regulate blood pressure. Cortisol also enhances the integrity of blood vessels and reduces alergic and inflammatory responses.

Under normal circumstances, your body maintains or regulates your natural cortisol levels. Most healthy adults have a high cortisol level first thing in the morning and a low cortisol level at night. But when you’re feeling stressed, your body secretes more cortisol. Cortisol is frequently referred to as the “stress hormone” because it’s also secreted in higher levels during the body’s fight or flight response to stress. It is also responsible for several stress-related changes in your body.

Small increases of cortisol produce positive effects like improved memory, reduced sensitivity to pain, and increased sustained energy. However, elevated cortisol levels from prolonged or chronic stress can cause side effects such as suppression of thyroid function, cognitive impairment, increased blood pressure, decreased bone density, and blood sugar imbalances. High levels of cortisol can also lower your immunity and inflammatory responses, as well as slow down the wound healing process. [Cortisol and The Stress Connection. John R. Lee, M.D. and Virginia Hopkins Virginia Hopkins Health Watch, One-to-One Inc., 2009]

Chronic stress leads to chronically high levels of cortisol in your body. This creates a need for higher levels of other hormones (e.g. thyroid, insulin, estrogen and testosterone) in order to do the same job.

Chronic high concentration of cortisol is toxic to brain cells and can cause short-term memory loss. A lifetime of high cortisol levels may be a primary contributor to Alzheimer’s disease and senile dementia. High cortisol is also a primary cause of osteoporosis. [Aeron Biotechnology, 2010]

I thought this was really important information and wanted to share it.   Remember, I am not a doctor, nor am I an expert on Cortisol.
