What causes hyponatremia (low blood sodium)? A low sodium level in the blood may result from excess water or fluid in the body, diluting the normal amount of sodium so that the concentration appears low.
Primary symptoms associated with too much or too little sodium affect the nervous system and include confusion, lethargy and muscle twitching. Alterations in sodium are connected to changes in the amount of water in the blood because sodium draws water. Decreased sodium lowers blood volume, causing the blood pressure to drop and the heart rate to increase. Sodium increases raise blood volume and cause fluid to accumulate, forcing your heart to work harder.
