Scottsdale, Arizona - Salt craving can sometimes be caused by a serious underlying medical condition, such as adrenal insufficiency or Bartter syndrome.

Adrenal insufficiency

Adrenal insufficiency (Addison's disease) can cause a salt craving that's new, persistent and excessive.

Signs and symptoms of Addison's disease include:

  • Craving salt
  • Muscle aches and weakness
  • Fatigue
  • Nausea and abdominal pain
  • Weight loss
  • Low blood pressure

Bartter syndrome

In some cases, salt craving is a symptom of a rare kidney disorder called Bartter syndrome.

Seek medical attention

Salt cravings should be evaluated by a doctor, especially if other symptoms are present. In the absence of a demonstrated sodium-losing cause, such as Addison's disease or Bartter syndrome, eating too much salt isn't good for you because it can increase your risk of developing high blood pressure.
