No. Potassium, magnesium, and overall diet pattern matter just as much as sodium reduction. Many people cut salt but still eat low-potassium, high-processed-food diets and see limited improvement.

Some people see measurable changes within 2-4 weeks of consistent dietary change. Full benefit typically builds over 2-3 months.

Possibly, but this decision must always be made with your doctor based on your actual readings over time — never adjust BP medication on your own.
