Eating too much salt can have a range of effects. In the short term, it may cause bloating, severe thirst, and a temporary rise in blood pressure. In severe cases, it may also lead to hypernatremia, which, if left untreated, can be fatal. In the long term, high salt diets may cause a rise in blood pressure and increase the risk of stomach cancer, heart disease, and premature death. (source: Urology of Virginia)
