A low sodium diet has a useful effect to reduce blood pressure, both in people with hypertension and in people with normal blood pressure. [7] Taken together, a low salt diet (median of approximately 4.4 g/day – approx 1800 mg sodium) in hypertensive people resulted in a decrease in systolic blood pressure by 4.2 mmHg, and in diastolic blood pressure by 2.1 mmHg.
Hyponatremia, or blood sodium levels below 135 mEq/L, causes brain cells to swell; the symptoms can be subtle and may include altered personality, lethargy, and confusion. In severe cases, when blood sodium falls below 115 mEq/L, stupor, muscle twitching or spasms, seizures, coma, and death can result. [15]
Neurological symptoms typically occur with very low levels of plasma sodium (usually <115 mmol/L). [1] When sodium levels in the blood become very low, water enters the brain cells and causes them to swell (cerebral edema). This results in increased pressure in the skull and causes hyponatremic encephalopathy.
In terms of environmental factors, dietary salt intake is the leading risk factor in the development of hypertension. [7] Salt sensitivity is characterized by an increase in blood pressure with an increase in dietary salt and is associated with various genetic, demographic, and physiological factors— African American populations, postmenopausal women, and older individuals carry a higher ...
Sodium is an essential nutrient that the body requires in small amounts, but eating too much of it can lead to high blood pressure and increased risk of heart attack, heart failure, stroke and ...
The U.S. Dietary Guidelines for Americans recommend eating a diet of 2300 mg of sodium a day or lower, with a recommendation of 1500 mg/day in adults who have elevated blood pressure; the 1500 mg/day is the low sodium level tested in the DASH-Sodium study. The DASH diet and the control diet at the lower salt levels were both successful in ...
