higher weight is associated with higher blood pressure levels; prospectively, baseline weight and weight gain predict higher blood pressure. The loss of weight is frequently associated with a decrease in blood pressure. These findings suggest that weight gain may pathophysiologically contribute to blood pressure elevation. In this review, we present data to indicate that the reverse is also true; persons of equal weight who had higher initial blood pressures gain more weight in the future. We also propose a plausible hypothesis to explain this reverse relationship
