I crave salt! all the time?

Often a sign of stress: Salt cravings are common but yours sounds extreme. The most serious medical problem known to be associated with this is addison's disease, which is due to low adrenal function. While addison's disease is rare, a much more common cause is a less severe form of adrenal stress often called adrenal fatigue, that is related to ongoing stress. Research suggests that in this situation salt can help relieve stress and have some antidepressant effects, but it is not the best long-term way of dealing with the problem. Salt cravings can also simply be a sign of dehydration or cause by fluid loss due to sweating, vomiting or diarrhea. According to chinese medicine theory, salt cravings are signs of imbalances of the kidney meridian (which is related to adrenal problems).

Iron deficiency: Agree with Dr. B. An other possible explanation is iron deficiency. You may try taking oral iron and multivitamins.
