QuestionMy husband constantly craves salt. What causes this?
Salt craving can sometimes be caused by a serious underlying medical condition, such as adrenal insufficiency or Bartter's syndrome.
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
- Nausea and abdominal pain
- Weight loss
- Low blood pressure
In some cases, salt craving is a symptom of a rare kidney disorder called Bartter's syndrome.
Seek medical attention
Your husband's 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's syndrome, eating too much salt isn't good for you because it can increase your risk of developing high blood pressure.
