Sodium

This category contains information for patients, their families and caregivers, about Sodium and the effects of an imbalance in sodium levels in the human body.

Most of the body's sodium is contained in the blood and in the fluid that surrounds the cells. Low sodium levels can cause blood pressure to decrease and the heart rate to increase. High levels of sodium in the blood cause fluid to accumulate in the area around the cells, creating swelling in the tissues.
