If you think you may have adrenal fatigue, the first thing to do is to make a list of your symptoms and see if you have been experiencing them regularly, or for a long period of time. Finding more information from a trusted source on the subject will help you to determine what your next step should be.
To properly discover if you are experiencing adrenal fatigue, you are best to do so with the assistance of a health care professional who is able to recognise the signs and symptoms, and is experienced with adrenal fatigue and its accompanying issues.
You will need to go through a thorough questionnaire that takes into account your past history, as well as your present symptoms in order to help determine what is going on in your body.
Functional pathology testing can also be carried out to measure your different hormone levels. There are tests that measure the levels of your stress hormones such as cortisol, your DHEA, your sex hormones, and your thyroid function. The results of these tests are all important markers for showing how well your adrenals are working.
There are also a couple of simple tests you can do at home to give you an indication of your adrenal function. Checking your blood pressure while you're lying down and then when you stand up can be a good indication of low adrenal function, if it is lower when you're standing. Another simple test is checking the contraction of your iris when you shine a torch from the side while in a darkened room. The length of time your iris is able to hold the contraction can be indicative of low adrenal function. If your pupil dilates within 2 minutes with the light still shining on it, there is a good possibility that you may have adrenal issues.
Recognising symptoms in your own body and carrying out the simple at-home tests can give you the information you need to find the help you need.
Adrenal fatigue is not a clear cut condition, but can have many side issues that need attention as well. To correctly determine what is going on for you and why you are experiencing certain symptoms, can be done more accurately with a combination of tests rather than just relying on one test alone.
If you are wanting to check your hormone levels, you will have to order the tests through a practitioner because the pathology labs don't deal directly with the public.
To sum things up...how to find out if you have adrenal fatigue:
recognise any symptoms and how long you've had them
do some research
do the at-home tests
find a practitioner who can help you
use functional pathology tests to identify what is going on for you
