    Area of Science:

    • Cardiology
    • Nephrology
    • Nutrition Science

    Background:

    • Hypertension is a prevalent condition requiring effective management.
    • Dietary factors, such as sodium intake, significantly influence blood pressure regulation.

    Purpose of the Study:

    • To investigate the impact of sodium (NaCl) restriction on blood pressure in hypertensive patients.
    • To compare the efficacy of sodium restriction with standard pharmacological treatment in severe hypertension.

    Main Methods:

    • A controlled study involving 48 participants with hypertension.
    • Categorization of participants into mild (diastolic blood pressure 90-105 mmHg) and severe (diastolic blood pressure >105 mmHg) hypertension groups.
    • Monitoring blood pressure changes in response to sodium restriction and comparing with a control group and chlorothiazide treatment.

    Main Results:

    • Sodium restriction led to reduced blood pressure in the mild hypertension group, with 75% achieving diastolic blood pressure below 90 mmHg.
    • In severe hypertension, sodium restriction demonstrated comparable blood pressure control to chlorothiazide (500 mg/day).

    Conclusions:

    • Dietary sodium restriction is an effective intervention for lowering blood pressure.
    • Sodium restriction should be considered the primary therapeutic approach for individuals with mild hypertension.
