The prevalence of hypertension tends to be higher in populations that consume diets rich in sodium.
How does high sodium cause hypertension?
Salt makes your body hold onto water. If you eat too much, the extra water in your blood means there is extra pressure on your blood vessel walls, raising your blood pressure.
Does sodium immediately affect blood pressure?
Consuming highly salty foods may begin to impair the functioning of blood vessels within 30 minutes.
What happens when sodium intake is high?
But too much sodium in the diet can lead to high blood pressure, heart disease, and stroke. It can also cause calcium losses, some of which may be pulled from the bone.
Thus, diets rich in sodium can cause hypertension.
