Ok. I was just looking info up. I have found explanations on it due to the body's aldosterone levels signaling a need for more sodium. I also found a lot about abductees craving salt.
I forgot to add before that I also have very low blood pressure. It runs in my family, as well.
And then there's this:
Treatment of Adrenal Fatigue
Low adrenal function is often very common, but often missed by standard blood tests. Low levels of adrenal cortisol can result in the following: hypoglycemia, fatigue, muscle aches, low blood sugar, sugar or salt craving, shakiness relieved with eating, moodiness, food sensitivities, allergies, recurrent infections, life stressful when symptoms began, dizzy when standing, low blood pressure, decrease ability to handle stress, decreased cognitive ability “brain fog”, swollen ankles-worse in PM, hypoglycemia under stress, need to lie down or rest after psychological or emotional stress, muscular weakness, difficulty getting out of bed, wiped out with exercise and/or inability to tolerate thyroid replacement. Proper treatment can have profound effects.http://hlmcenter.com/osc/aboutus.php
Dude, that is me to a tee. Except the swollen ankles and I don't always have brain fog...
That's weird. Maybe I should talk to a doctor about this.
