The doctor can order tests to measure the level of cortisol in your urine, blood, or saliva. The urine test is often done over the course of a full 24 hours (called a 24-hour urine sample test), since cortisol levels naturally vary throughout the day.
The test itself is simple: A nurse or lab technician will use a needle to take a blood sample from a vein in your arm. Your results will show the level of cortisol in your blood at the time of the test. Your doctor will tell you if yours falls in the normal range.
According to Mayo Clinic, signs and symptoms associated with excess cortisol levels can include: Rapid weight gain mainly in the face, chest, and abdomen. A flushed and round face. High blood pressure.
Low cortisol levels can cause any of the following symptoms: Fatigue and morning sluggishness. Depression. Anxiety.
The adrenal fatigue theory suggests that prolonged exposure to stress could drain the adrenals leading to a low cortisol state. The adrenal depletion would cause brain fog, low energy, depressive mood, salt and sweet cravings, lightheadedness, and other vague symptoms.
If a person believes they have high or low cortisol levels, they may wish to take a cortisol test. Usually, these tests take place at a medical practice. However, several at-home cortisol tests are available to purchase. A person can take these tests at home by providing a urine, blood, or saliva sample.
A little cortisol goes a long way.
Cortisol levels remain elevated, creating additional anxiety, and ultimately causing a multitude of serious health issues, including digestive disorders, immune deficiencies, heart disease, high blood pressure, and diabetes.
Normal values for a blood sample taken at 8 in the morning are 5 to 25 mcg/dL or 140 to 690 nmol/L.
Finally, recent studies suggest that overthinking may be related to an increase in cortisol – the primary hormone released when you experience stress or anxiety – in the bloodstream which has been linked with developing physical illnesses such as heart disease and stroke.
Remember magnesium will help lower cortisol, if you do not have adequate levels of magnesium your body cannot relax and remove excess cortisol.
Adding in cardio, such as a brisk walk will help lower your cortisol levels and control your stress. Once you have your stress under control, you can add interval training and sprints two or three times a week to reduce your belly fat.
Fish oil is the most popular supplemental source of omega-3 essential fatty acids. Fish oil supplements have positive effects on brain functions of all kinds — mood, memory, cognition, and general mental well-being. One of the ways it works is by blunting the stress response and effectively reducing cortisol levels.
There is, in fact, a chemical reason why you get more stressed, as when you're even mildly dehydrated cortisol levels in the body increase. Cortisol production is triggered by the stress response. And one way to balance these chemicals in your brain? Drink more water.
The body's stress response system is usually self-limiting. Once a perceived threat has passed, hormone levels return to normal. As adrenaline and cortisol levels drop, your heart rate and blood pressure return to baseline levels, and other systems resume their regular activities.
Lack of cortisol can cause adrenal crisis, a preventable condition that can cause death if treated improperly. Deaths from adrenal crisis can be prevented if patients and their families recognize the condition and are careful to treat it right away. Adrenal crisis is a medical emergency.
Other reasons your cortisol level may be higher than normal include depression, alcoholism, malnutrition, and panic disorder. A number of medicines, especially oral contraceptives and any medicine that contains glucocorticoids, or steroid hormones similar to cortisol, can also affect your cortisol levels.
It's not just your imagination: Constantly elevated stress levels mess with your head. Research suggests that elevated cortisol levels can cause “wear and tear” to the brain and body, particularly in older adults. Over time, this can lead to higher anxiety levels, as well as mood changes like irritability.
Cortisol is the main villain who creates unhealthy overthinking and is released in the hypothalamus – a region very near to the centre of your brain.
Your doctor will likely have you do the test early in the morning. This is important, because cortisol level varies throughout the day. You may be asked not to do any vigorous exercising the day before the test.
