What causes salt craving?
Salt craving is a demanding or extreme desire to consume salt or salty foods. Craving for salt is a common symptom of Addison’s disease (decreased production of hormones by the adrenal glands), dehydration, and electrolyte imbalances. Craving for salt results from a decrease in sodium in the body from either an inability to retain salt, such as with Addison’s disease, or the loss of sodium, such as occurs with excessive sweating and fluid loss or dehydration. Salt craving is common during pregnancy.
