Salt Craving Symptoms

Salt is a vital part of the diet. You cannot survive without it. Humans are strongly driven to seek out salt and make sure enough is available, even though our modern diets of processed food tend to contain very high amounts of salt, in fact, nine out of 10 Americans consume too much [1]. Yet it isn't normal to be eating plenty of salt each day and still constantly crave it.

Salt is something of a stimulant, because it raises the blood pressure, and you like the taste because normally salt is good for you. Some researchers believe you can become addicted to it if you get used to eating very high amounts.

However, a sudden and intense salt craving that you didn't have before can be a sign of serious illness or imbalance. It is a reason to consult the medical provider.

Salt is also referred to as sodium chloride, NaCl, or common table salt. Excessive salt craving is also called "salt hunger" [2].

Salt craving characteristics, all of which are symptoms of sodium/salt deficiency:


  • Sometimes you can develop a taste and a tolerance for greater and greater amounts of salt, until you are eating so much that it can be harmful.
  • Depression can result from long-term salt hunger [3].

Who is most often affected by salt craving symptoms? If a mother consumes a high-salt diet while pregnant, her child may also want larger amounts of salt in his or her diet once he or she reaches about three years of age.

Where in the world are these salt craving symptoms most common?

  • In underdeveloped or "third world" areas, where extra salt may be only sporadically available.
  • In hot climates where people normally have to do heavy work in high temperatures.

When are salt craving symptoms most likely to occur?

  • While doing heavy work, or training for a sport, in a hot environment that causes profuse sweating.

  • Overeating salt can lead to chemical and nutritional imbalances, as well as to high blood pressure.
  • The symptom of excessive salt craving can be a symptom of other illnesses, some of which are serious, and should be brought to the attention of the medical provider.

A.I. Health Assistant Causes for Salt Craving

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced salt craving. This list does not constitute medical advice.

  1. 1.Adrenal Insufficiency

    The adrenal gland's outer layer produces hormones such as cortisol and aldosterone, which control many important functions of the body such as blood sugar and blood pressure regulation, and urine production. In adrenal insufficiency, not enough of these hormones are produced, leading to symptoms such as fatigue and weakness, appetite and weight loss, nausea, and vomiting.

    Adrenal insufficiency is a chronic condition that requires lifelong management, and can be fatal if not treated.
