Understanding Cortisol Function: 8 Symptoms To Watch Out For

Prolonged stress coupled with underlying health conditions can increase your cortisol levels. High cortisol levels can lead to a number of conditions, such as weight gain, acne and fatigue. The adrenal glands, located above the kidneys, make cortisol and maintain stress hormone levels.

What is cortisol?

Cortisol is a stress hormone that acts like an internal alarm system. It interacts with various parts of the brain to regulate mood, motivation, and fear. Glucocorticoids, a steroid hormone, suppress inflammation in bodily tissues and regulate metabolism in muscles, fat, and bones. They also influence sleep cycles.

Cortisol is crucial for almost every organ and tissue, playing many vital roles, including:

Regulating the body’s stress प्रतिक्रिया
Managing the metabolism of fats, proteins, and carbohydrates
Suppressing inflammation
Controlling blood pressure
Regulating ब्लड शुगर की मात्रा
Influencing the circadian cycle

The role of cortisol in the body’s stress response

During stress, your body releases cortisol following the “fight or flight” response caused by hormones like adrenaline to keep you on high alert. Cortisol also prompts the liver to release glucose (sugar) for quick energy during stressful situations.

Functions of cortisol

Cortisol and blood sugar regulation

Under normal conditions, cortisol balances the effect of insulin, a hormone produced by the pancreas, on blood sugar regulation. Cortisol raises blood sugar by releasing stored glucose, while insulin lowers it. Chronically high cortisol levels can lead to persistent high blood sugar (hyperglycemia), potentially causing टाइप-2 डायबिटीज.

Cortisol and immune system function

Cortisol is anti-inflammatory and regulates natural immune response. However, chronic elevations can cause the immune system to become “resistant,” leading to a buildup of stress hormones and increased production of inflammatory cytokines, further weakening the immune response.

Cortisol and metabolism

Cortisol helps control how your body responds to the fats, protein and carbohydrates you consume for energy.

Understanding cortisol levels

Cortisol levels in your body usually peak in the early morning and decrease throughout the day, reaching their lowest point around midnight. This pattern can shift if you work night shifts and sleep at different times.

For most blood tests measuring cortisol levels, the normal ranges are:

6 a.m. to 8 a.m.: 10 to 20 micrograms per deciliter (mcg/dL)
Around 4 p.m.: 3 to 10 mcg/dL

Normal ranges can vary based on the lab, the time of day, and individual differences.

Symptoms of high cortisol levels

Common signs and symptoms of high cortisol levels are:

Weight gain, particularly in the face and abdomen.
Fatty deposits between the shoulder blades.
Wide, purple stretch marks on the abdomen.
Muscle weakness in the upper arms and thighs.
High blood sugar, often leading to टाइप-2 डायबिटीज.
हाई ब्लड प्रेशर (हाइपरटेंशन).
Excessive hair growth (hirsutism) in individuals assigned female at birth.
Weak bones (osteoporosis) and fractures.

You must contact your healthcare provider if you experience abnormal cortisol level symptoms, such as weight gain or sudden high or low blood pressure. They can conduct simple tests to determine if your other glands, such as the pituitary, are responsible for your symptoms.
