The Cortisol Test measures free cortisol levels at multiple points during the day to track fluctuations. Cortisol, produced by the adrenal glands, plays a vital role in regulating metabolism, managing stress, and supporting immune function. While short-term increases help improve performance under stress, prolonged high cortisol levels can negatively impact health, leading to issues such as high blood pressure, elevated blood sugar, and increased risk of type-2 diabetes. Low cortisol, on the other hand, can lead to fatigue, muscle weakness, and more serious conditions like adrenal insufficiency.
How Cortisol Works Cortisol is often referred to as the stress hormone because it's released during stressful situations. However, it also has essential functions beyond stress response, such as regulating blood sugar, metabolism, and immune reactions. It can help reduce inflammation but can also make the body more susceptible to infections. Physical activity also triggers cortisol release, but in this case, it helps reduce muscle inflammation.
Cortisol Fluctuations Cortisol levels naturally peak in the morning and decline throughout the day. These levels are influenced by daily activities and stress. Factors such as injuries, infections, or high adrenaline levels can raise cortisol, while low levels are often linked to conditions like adrenal insufficiency.
Symptoms of High Cortisol Prolonged elevated cortisol can reduce fat metabolism, increase the risk of diabetes, and lead to obesity. Common symptoms include:
- Fatigue
- Weight gain
- Difficulty sleeping
- High blood pressure
- Poor immune function
Symptoms of Low Cortisol Low cortisol can cause fatigue, menstrual disorders, low blood pressure, and appetite loss. In severe cases, it can result in adrenal insufficiency (Addison's disease), which is life-threatening if untreated.
Why a Saliva Test? Saliva testing offers a more convenient and comfortable way to measure cortisol levels throughout the day, avoiding the need for blood draws. It’s particularly helpful for those with sensitive skin or needle anxiety.
This test is ideal for individuals experiencing chronic stress, fatigue, or other related symptoms
