What is salt craving? Salt craving is a compelling or extreme desire to consume salt or salty foods. Craving for salt results from a decrease in sodium in the body either from inability to retain salt or the excess loss of sodium from the body. Salt craving is common during pregnancy. Craving for salt is also a common symptom of Addison’s disease (decreased production of hormones by the adrenal glands), dehydration, and electrolyte imbalances. Depending on the cause, your salt craving may last only as long as it takes to rehydrate following mild dehydration from heavy sweating. It may also be a permanent symptom, as is found with Addison’s disease, and may be accompanied by other symptoms or signs including low blood pressure (hypotension), fatigue, loss of appetite, and chronic diarrhea. Left untreated, salt craving due to severe dehydration is a serious condition. Severe dehydration and electrolyte imbalances can result in shock or coma and may be life threatening. Seek immediate medical care (call 911) if you, or someone you are with, have symptoms of severe dehydration, such as confusion or loss of consciousness for even a brief moment, lethargy, cold skin, or inability to urinate or reduced urine output.
