I found out recently that on top of fibromyalgia, I also have adrenal fatigue. That enlightened me, because I could not figure out why my fatigue was so bad. The fatigue is severe enough to keep me in bed at least 90 percent of my day. My doctor had ordered an adrenal test that consisted of putting a sponge-type material under my tongue; once in the morning and again eight hours later. The interesting thing is that the directions were to keep it under your tongue for two minutes, then place it in a sterile tube. Because I have very dry mouth, I had to leave it under my tongue for 10 minutes just to get enough saliva! If you're curious like I am, you may be wondering if there is a connection between fibro and adrenal fatigue. The adrenal glands sit on top of the kidneys and produce the hormone cortisol. It's one of the hormones produced by the adrenal glands. Cortisol helps to regulate blood sugar and blood pressure, among other things. It also helps to protect our cells and keep our body systems in balance. I'm sure by now you're wondering what the symptoms of adrenal fatigue are. Bethany Sharp, Mrs. Tennessee 2012, shares her symptoms in a video. It causes fatigue, dizziness, brain fog, waking in the middle of the night, difficulty getting back to sleep, lethargy, decreased ability to handle stress, low body temperature, muscle weakness, and hair loss, to name a few.
