Most people know salt raises BP, but the real impact is deeper and far more mechanical.
1. Sodium increases blood volume
When sodium rises, your body holds extra water to dilute it.
More volume = more pressure = more force required from the heart.
2. Salt tightens your blood vessels
High sodium triggers hormones that constrict arteries.
Narrower vessels + more fluid = a constant pressure overload.
3. Pressure damages artery walls
Over time, high pressure roughens the inner lining, making it easier for LDL to stick.
Salt indirectly accelerates plaque formation.
4. The heart muscle thickens to cope
To push against resistance, the heart slowly enlarges (LVH).
It’s a survival response, but reduces long-term efficiency.
5. Most salt comes from foods we don’t suspect
Namkeen, chips, bakery items, pickles, instant noodles, and restaurant gravies contribute far more sodium than the salt we add at home.
6. Lowering salt brings quick benefits
Within 2–6 weeks: BP stabilizes, bloating reduces, vessel stiffness improves, and your taste resets.
Small sodium cuts → measurable heart protection.
It’s one of the simplest forms of prevention we have.
