FIGURE 1.

Determination of Salt-Sensitivity of BP. The recommended method to diagnose salt-sensitivity involves exposure to a 1-week high salt diet phase followed by a 1-week low salt diet phase, that is accompanied with BP measurements. If the BP increase is equal to or exceeds 3–5 mmHg, the individual is considered a normotensive salt-sensitive individual. If the BP change is below 3–5 mmHg, the individual is considered salt-resistant. If the BP change is equal to or exceeds 8–10 mm Hg, the individual is classified as a hypertensive salt-sensitive individual.
