I think that I read in one of these articles There are two good articles on adrenal crisis. 1) Go to http://www.emedicine.com - and then "search textbooks" and then search "adrenal crisis" 2) Go to http://www.healthanswers.com - and then search "acute adrenal crisis" That a mood swing was a symptom of an adrenal crisis or that the adrenal condition was not under control. But if the adrenal condition is being managed right - the OH17, plasma renin and chem 8 blood tests are normal. The blood pressure, etc. Then look at family history and look health or medical reasons. Make sure that the OH17 blood test is done without the meds and before 8am because of the hormonal surge in the am. The blood pressure is very important too. Check the blood pressure for a couple of weeks every day - at different times of the day. The food or grocery stores, and drug stores have free blood pressure machines. Write it down and keep a journal. Also the sugar levels are easy to test too. preston@kreative.net
