If you have unbalanced levels of cortisol, you can experience unpleasant symptoms. Learn more about cortisol and how to test your levels with at-home sample collection.


Are you constantly fatigued or irritable? Are you inexplicably gaining weight or dealing with an awful case of brain fog? Overly high or low cortisol levels could be the cause of these symptoms.

If you want to learn more about cortisol and how it affects the body, read on. We detail the symptoms of too much and too little cortisol and explain how to check your cortisol levels at home.

What Is Cortisol?

The endocrine glands above your kidneys, called the adrenal glands, produce the steroid hormone cortisol. Cortisol manages several vital processes throughout your body, including your metabolism and immune response.

Why Is Cortisol Important?

Having too much or too little cortisol in your body can adversely affect your mental and physical well-being. If you have low levels of cortisol, you may experience symptoms such as fatigue, depression, increased susceptibility to illness, brain fog, and strong cravings for sweet or salty foods. Elevated cortisol levels, on the other hand, can cause issues such as weight gain in the face, midsection, and upper back, thinning skin, acne, muscle weakness, fatigue, irritability, difficulty concentrating, and headaches.

How To Check Cortisol Levels at Home

At RxHomeTest, we have a 24-hour cortisol test (four samples) and a day and night cortisol test (two samples) available. Buy a cortisol saliva test, collect your saliva samples using the provided instructions, and ship them off to our labs, where a healthcare provider will review them and craft a detailed and easy-to-understand report. Make sure to pay special attention to the morning sample since that's when levels change quickly.

If your test results indicate you have depleted or elevated cortisol levels, you can take them to the doctor or work on improving your health by exercising, eating well, limiting caffeine and alcohol consumption, and getting between 7 and 9 hours of sleep per night. But if symptoms continue, you could potentially have an endocrine condition, such as Addison's disease, Cushing's syndrome, or congenital adrenal hyperplasia, that requires professional diagnosis and treatment. Consult with your doctor for additional testing and to find a treatment plan that works for you.
