What is Cortisol?

Your adrenal glands, which are located atop your kidneys, produce the steroid hormone cortisol. It’s a key player in your body’s stress response, surging when you encounter challenging situations to help you cope. While often associated with stress, cortisol is essential for many normal bodily functions.

Etymology and History:

• Cortisol: This name is derived from its source, the adrenal cortex, and its chemical structure as a sterol (a type of alcohol). The term was first used in the mid-20th centuryA century is a period of 100 years. Examples: • The 21st Century: The years 2000 to 2099. • The 19th Century: The years 1800 to 1899. • The 8th Century BC: The years 800 BC to 701 BC. Etymology:… Read More, following the isolation and identification of cortisol by American scientists Edward Kendall and Philip Hench.

Cortisol in Everyday Life and Medicine:

• Stressful Situations: “My cortisol levels spiked when I had to give a presentation in front of a large audience.”
• Chronic Stress: “Long-termChronic simply means “happening over a long period of time” or “of long duration.” Imagine a situation that keeps going on and on, unlike something short-lived. • Other Names: You might not encounter many other terms for chronic in everyday… Read More exposure to stress can lead to chronically elevated cortisol levels, which can have negative health effects.”
• Medical Diagnosis: “The doctor ordered a cortisol test to check for adrenal gland dysfunction.”

Cortisol and Metabolism: A Complex Relationship

Cortisol plays a multifaceted role in metabolism, influencing how your body utilizes energy from food:

Cortisol Levels in Health and Disease

Cortisol levels naturally fluctuate throughout the day, peaking in the morning and gradually declining in the evening. However, chronic stress, sleep deprivation, and certain medical conditions can disrupt this natural rhythm and lead to consistently high cortisol levels.

• Lab Tests: Cortisol levels are measured through blood, saliva, or urine tests. These tests can help diagnose conditions like Cushing’s syndrome (excess cortisol) or Addison’s disease (cortisol deficiency).

The Impact of Sugar on Cortisol:

While sugar doesn’t directly cause cortisol production, it can create a vicious cycle. Consuming sugary foods can result in a quick spike in blood sugar and a subsequent crash, which sets off a stress response and increases cortisol levels. Over time, this pattern can contribute to chronic stress and elevated cortisol levels, disrupting your metabolism and overall health.

• Interesting Fact: Cortisol is released in response to both physical and emotional stress.
