Fluid and Electrolyte Balance

Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine and body fluids. Maintaining the right balance of electrolytes helps your body's blood chemistry, muscle action and other processes. Sodium, calcium, potassium, chlorine, phosphate and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink.

Levels of electrolytes in your body can become too low or too high. That can happen when the amount of water in your body changes, causing dehydration or overhydration. Causes include some medicines, vomiting, diarrhea, sweating or kidney problems. Problems most often occur with levels of sodium, potassium or calcium.

Also called: Salt

Table salt is a combination of two minerals - sodium and chloride Your body needs some sodium to work properly. It helps with the function of nerves and muscles. It also helps to keep the right balance of fluids in your body. Your kidneys control how much sodium is in your body. If you have too much and your kidneys can't get rid it, sodium builds up in your blood. This can lead to high blood pressure. High blood pressure can lead to other health problems.

Most people in the U.S. get more sodium in their diets than they need. A key to healthy eating is choosing foods low in sodium. The Dietary Guidelines recommend that most adults eat less than 2.3 grams per day. That equals about 1 teaspoon of table salt a day. Some people are more sensitive to the effects of salt than others and should eat less. This includes people who have high blood pressure, diabetes, or kidney problems, or are African-American or over age 50. Reading food labels can help you see how much sodium is in prepared foods.
