Electrolytes are salts in the body that conduct electricity and are found in the body fluid, tissue, and blood. Examples are chloride, calcium, magnesium, sodium, and potassium. Sodium (Na+) is concentrated in the extracellular fluid between tissue cells and potassium (K+) is concentrated in the intracellular fluid within the blood vessels. Proper balance is essential for muscle coordination, heart function, fluid absorption and excretion, nerve function, and concentration.The kidneys regulate fluid absorption and excretion and maintain a narrow range of electrolyte fluctuation. Normally, sodium and potassium are filtered and excreted in the urine and feces according to the body’s needs. Too much or too little sodium or potassium, caused by poor diet, dehydration, medication, and disease, results in an imbalance.
Fluids in the body contain water and a variety of dissolved chemicals. Some of these chemicals exist in the form of compounds called electrolytes. Electrolytes are needed for metabolism, for movement of fluids and for normal cellular activities.
Electrolyte levels are controlled by hormones.
Adrenals produce hormones
The adrenal glands are located on the top of each kidney. The adrenals produce about 50 hormones. They produce the hormones adrenaline, epinephrine and norepinephrine, which are responsible for our fight or flight response. They also produce hormones which allow our muscles to grow and our carbohydrates and electrolytes to be metabolized.
About two-thirds of the body's fluid is intracellular (located inside cells). The other third is extracellular (located outside cells).
Extracellular fluid contains large amounts of sodium, but only small amounts of potassium.
Intracellular fluids contain just the opposite. Extracellular fluids supply the cells with nutrients and other substances needed for cellular function. But, before the cell can utilize these substances, they must be transported through the cell membrane.
Both the amount of water and the concentration of electrolytes are important to bodily functions. When the body is “in fluid balance” it means that the various body compartments (cells, tissues, organs) contain the required amount of fluids to carry out normal bodily functions. Fluid balance and electrolyte balance are inseparable. In a healthy individual, the volume of fluid in each compartment remains stable.
The chemical elements of electrolytes are sodium, chloride, potassium, calcium, phosphate and magnesium. Loss of electrolytes can have serious consequences for the body. In severe dehydration, the loss of electrolytes can result in circulatory problems such as tachycardia (rapid heart beat) and problems with the nervous system such as loss of consciousness and shock.
Electrolytes Serve Three General Functions
2. Electrolytes are needed for proper fluid movement between compartments (from cell to cell, from tissue to tissue, and from organ to organ). The walls of compartments are semipermeable. Through osmosis, fluids are in constant movement from one compartment to another within fractions of a second. The concentration (and the nature) of the solutes in the fluids are a major determinant of fluid balance.
3. Electrolytes help maintain the acid-base (Alkalinity) balance required for normal cellular activities.
In a healthy person pH is between 6.4 and 7.00.
Loss of Electrolytes can occur through long term laxative use and use of diuretic medications. It can also result from vomiting, diarrhea and any form of water loss that results in dehydration. Sodium can also be lost through excessive perspiration and burns.
Chemical Elements of Electrolytes
Sodium is necessary for nerve impulse transmission, muscular contraction and fluid and electrolyte balance. Sodium level in the blood is controlled by aldosterone. Hyponatremia, a lower than normal blood sodium level, is characterized by muscular weakness, headache, hypotension, tachycardia, and circulatory shock. Severe hyponatremia can result in mental confusion, stupor and coma.
Chloride can easily diffuse between extracellular and intracellular compartments. This makes chloride important in regulating osmotic pressure differences between compartments. Chloride level is indirectly controlled by aldosterone.
Potassium helps to maintain fluid volume in cells and regulates pH.
Calcium and Phosphate are stored in the bones and teeth and released when needed. Calcium and phosphate are structural components of bones and teeth. Calcium required for blood clotting, chemical transmitter release, muscle contraction and normal heartbeat. Phosphate is necessary for the formation of nucleic acids, the synthesis of high energy compounds and buffering reactions. Calcium and phosphate levels in the blood are regulated by several hormones.
Magnesium is important for the sodium-potassium pump which controls the volume of the cells.
