    Hyponatremia

    A condition where the sodium level in the blood is lower than 135 mmol/L.

    What causes hyponatremia?

    A decrease in sodium levels in the blood, often caused by excessive loss of sodium or an increase in water retention.

    Hypoadrenalism

    A medical condition where the adrenal glands don't produce enough hormones, leading to sodium loss and potential hyponatremia.

    Potassium Deficiency

    A deficiency of potassium in the body, potentially leading to increased sodium loss and hyponatremia.
