Electrolytes carry an electric charge when dissolved in body fluids such as blood read morehelp the body maintain normal fluid levels in the fluid compartments because the amount of fluid a compartment contains depends on the amount concentration of electrolytes in it.

If the electrolyte concentration is high, fluid moves into that compartment a process called osmosis. Likewise, if the electrolyte concentration is low, fluid moves out of that compartment. To adjust fluid levels, the body can actively move electrolytes in or out of cells. Thus, having electrolytes in the right concentrations called electrolyte balance is important in maintaining fluid balance among the compartments.

The kidneys help maintain electrolyte concentrations Water and electrolyte balance The kidneys are bean-shaped organs that figure prominently in the urinary tract. Each is about 4 to 5 inches 12 centimeters long and weighs about one third of a pound grams.

One lies read more by filtering electrolytes and water from blood, returning some to the blood, and excreting any excess into the urine.

Thus, the kidneys help maintain a balance between the electrolytes a person takes in every day by consuming food and beverages and the electrolytes and water that pass out of the body in the urine are excreted.

If the balance of electrolytes is disturbed, a person can develop health issues. For example, an electrolyte imbalance can result from the following:. Becoming dehydrated Dehydration Dehydration is a deficiency of water in the body. Vomiting, diarrhea, excessive sweating, burns, kidney failure, and use of diuretics may cause dehydration.

It helps establish the resting membrane potential in neurons and muscle fibers after membrane depolarization and action potentials. In contrast to sodium, potassium has very little effect on osmotic pressure. The low levels of potassium in blood and CSF are due to the sodium-potassium pumps in cell membranes, which maintain the normal potassium concentration gradients between the ICF and ECF.

Potassium is excreted, both actively and passively, through the renal tubules, especially the distal convoluted tubule and collecting ducts.

Potassium participates in the exchange with sodium in the renal tubules under the influence of aldosterone, which also relies on basolateral sodium-potassium pumps.

Hypokalemia is an abnormally low potassium blood level. Similar to the situation with hyponatremia, hypokalemia can occur because of either an absolute reduction of potassium in the body or a relative reduction of potassium in the blood due to the redistribution of potassium.

An absolute loss of potassium can arise from decreased intake, frequently related to starvation. It can also come about from vomiting, diarrhea, or alkalosis. Some insulin-dependent diabetic patients experience a relative reduction of potassium in the blood from the redistribution of potassium.

When insulin is administered and glucose is taken up by cells, potassium passes through the cell membrane along with glucose, decreasing the amount of potassium in the blood and IF, which can cause hyperpolarization of the cell membranes of neurons, reducing their responses to stimuli.

Hyperkalemia , an elevated potassium blood level, also can impair the function of skeletal muscles, the nervous system, and the heart. Hyperkalemia can result from increased dietary intake of potassium. In such a situation, potassium from the blood ends up in the ECF in abnormally high concentrations.

This can result in a partial depolarization excitation of the plasma membrane of skeletal muscle fibers, neurons, and cardiac cells of the heart, and can also lead to an inability of cells to repolarize. Because of such effects on the nervous system, a person with hyperkalemia may also exhibit mental confusion, numbness, and weakened respiratory muscles.

Chloride is the predominant extracellular anion. Chloride is a major contributor to the osmotic pressure gradient between the ICF and ECF, and plays an important role in maintaining proper hydration.

Chloride functions to balance cations in the ECF, maintaining the electrical neutrality of this fluid. The paths of secretion and reabsorption of chloride ions in the renal system follow the paths of sodium ions.

Hypochloremia , or lower-than-normal blood chloride levels, can occur because of defective renal tubular absorption. Vomiting, diarrhea, and metabolic acidosis can also lead to hypochloremia.

Hyperchloremia , or higher-than-normal blood chloride levels, can occur due to dehydration, excessive intake of dietary salt NaCl or swallowing of sea water, aspirin intoxication, congestive heart failure, and the hereditary, chronic lung disease, cystic fibrosis.

In people who have cystic fibrosis, chloride levels in sweat are two to five times those of normal levels, and analysis of sweat is often used in the diagnosis of the disease.

Watch this video to see an explanation of the effect of seawater on humans. What effect does drinking seawater have on the body? Bicarbonate is the second most abundant anion in the blood. This role will be discussed in a different section.

Bicarbonate ions result from a chemical reaction that starts with carbon dioxide CO 2 and water, two molecules that are produced at the end of aerobic metabolism. Only a small amount of CO 2 can be dissolved in body fluids. Thus, over 90 percent of the CO 2 is converted into bicarbonate ions, HCO 3 — , through the following reactions:.

The bidirectional arrows indicate that the reactions can go in either direction, depending on the concentrations of the reactants and products. Carbon dioxide is produced in large amounts in tissues that have a high metabolic rate. Carbon dioxide is converted into bicarbonate in the cytoplasm of red blood cells through the action of an enzyme called carbonic anhydrase.

Bicarbonate is transported in the blood. Once in the lungs, the reactions reverse direction, and CO 2 is regenerated from bicarbonate to be exhaled as metabolic waste. About two pounds of calcium in your body are bound up in bone, which provides hardness to the bone and serves as a mineral reserve for calcium and its salts for the rest of the tissues.

Teeth also have a high concentration of calcium within them. A little more than one-half of blood calcium is bound to proteins, leaving the rest in its ionized form. In addition, calcium helps to stabilize cell membranes and is essential for the release of neurotransmitters from neurons and of hormones from endocrine glands.

Calcium is absorbed through the intestines under the influence of activated vitamin D. A deficiency of vitamin D leads to a decrease in absorbed calcium and, eventually, a depletion of calcium stores from the skeletal system, potentially leading to rickets in children and osteomalacia in adults, contributing to osteoporosis.

Electrolytes, particularly sodium Overview of Sodium's Role in the Body Sodium is one of the body's electrolytes, which are minerals that the body needs in relatively large amounts.

Electrolytes carry an electric charge when dissolved in body fluids such as blood read more , help the body maintain normal fluid levels in the fluid compartments because the amount of fluid a compartment contains depends on the amount concentration of electrolytes in it.

If the electrolyte concentration is high, fluid moves into that compartment a process called osmosis. Likewise, if the electrolyte concentration is low, fluid moves out of that compartment.

To adjust fluid levels, the body can actively move electrolytes in or out of cells. Thus, having electrolytes in the right concentrations called electrolyte balance is important in maintaining fluid balance among the compartments.

Thus, the kidneys help maintain a balance between the electrolytes a person takes in every day by consuming food and beverages and the electrolytes and water that pass out of the body in the urine are excreted.

If the balance of electrolytes is disturbed, a person can develop health issues. For example, an electrolyte imbalance can result from the following:. It is advisable for a person to see a doctor if they experience severe symptoms such as convulsions, seizures, or rapid blood pressure changes.

A doctor can determine whether the person has an electrolyte imbalance or another condition, as well as the appropriate treatment. By consuming a balanced diet, which includes nutritious foods and drinks, a person can typically supply the body with the necessary minerals to support a healthy electrolyte balance.

This means ensuring that the diet includes fruits and vegetables rich in electrolytes, as well as other healthy sources of essential minerals. It is also important to maintain hydration throughout the day. People who exercise should pay close attention to their fluid intake.

Mild to moderate workouts may only require water, while longer and more intense workouts may call for more robust electrolyte drinks. People experiencing symptoms such as diarrhea or vomiting may also want to pay attention to their fluid intake and consider an oral electrolyte solution to avoid dehydration.

Anyone experiencing symptoms of an electrolyte imbalance should consider consulting their doctor. Most people who maintain a healthy diet and stay hydrated will not require electrolyte drinks. But they can provide a quick and convenient way for athletes to replenish electrolytes lost from sweat or help people with severe diarrhea or vomiting stay hydrated and maintain their electrolyte balance.

But if a person regularly consumes electrolyte drinks, they may consume more than is necessary, which can have associated risks. For example, this could result in hypernatremia , hyperkalemia , or hypercalcemia.

These are when a person has too much sodium, potassium, or calcium in the blood. Electrolytes are essential minerals that play a key role in a number of bodily functions. Typically, people can get sufficient levels of electrolytes from their diet.

But an electrolyte-rich beverage may be beneficial for athletes engaging in intense exercise or people who are ill and at risk for dehydration. People can make an electrolyte-rich beverage at home by mixing salt, sugar, and water.

But people should try to maintain healthy electrolyte levels, as too much or too little can result in an imbalance, which can have associated risks. Anyone who has concerns about their electrolyte level should contact their doctor.
