Electrolyte balance for health -
Parathyroid hormone also regulates calcium secretion in the distal tubule of the kidneys. Hypocalcemia diagnosis requires checking the serum albumin level to correct for total calcium.
Hypocalcemia is diagnosed when the corrected serum total calcium levels are less than 8. Checking serum calcium levels is a recommended test in post-thyroidectomy patients. Humoral hypercalcemia presents in malignancy, primarily due to PTHrP secretion. The acid-base status of the blood drives bicarbonate levels.
The kidneys predominantly regulate bicarbonate concentration and maintain the acid-base balance. Kidneys reabsorb the filtered bicarbonate and generate new bicarbonate by net acid excretion, which occurs through the excretion of titrable acid and ammonia.
Diarrhea usually results in bicarbonate loss, causing an imbalance in acid-base regulation. Magnesium is an intracellular cation. Magnesium is mainly involved in adenosine triphosphate ATP metabolism, proper functioning of muscles, neurological functioning, and neurotransmitter release.
When muscles contract, calcium re-uptake by the calcium-activated ATPase of the sarcoplasmic reticulum is brought about by magnesium. Alcohol use disorder, gastrointestinal conditions, and excessive renal loss may result in hypomagnesemia.
It commonly presents with ventricular arrhythmias, which include torsades de pointes. Hypomagnesemia may also result from the use of certain medications, such as omeprazole. Chloride is an anion found predominantly in the extracellular fluid.
The kidneys predominantly regulate serum chloride levels. Most chloride, filtered by the glomerulus, is reabsorbed by both proximal and distal tubules majorly by proximal tubule by both active and passive transport. Hyperchloremia can occur due to gastrointestinal bicarbonate loss.
Hypochloremia presents in gastrointestinal losses like vomiting or excess water gain like congestive heart failure.
Phosphorus is an extracellular fluid cation. Phosphate plays a crucial role in metabolic pathways. It is a component of many metabolic intermediates and, most importantly, of ATP and nucleotides. Vitamin D3, PTH, and calcitonin regulate phosphate simultaneously with calcium.
The kidneys are the primary avenue of phosphorus excretion. Phosphate imbalance is most commonly due to one of three processes: impaired dietary intake, gastrointestinal disorders, and deranged renal excretion. A blood specimen for electrolytes uses lithium heparin tubes, plus the standard phlebotomy equipment and personnel, as with any blood draw.
Blood is collected in lithium heparin tubes and then goes to the laboratory to evaluate serum electrolytes. Measurement of electrolytes will help clinicians in the diagnosis of a medical condition, the effectiveness of treatment, and the potential side effect of medications.
Examples include:. A patient with heart failure receiving diuretics needs a workup for sodium, potassium, bicarbonate, and magnesium, as diuretics can exert adverse effects on electrolyte balance.
A patient that presents with weakness needs a basic electrolyte workup, as an electrolyte imbalance, especially in sodium and potassium levels, can lead to generalized weakness.
A patient with gastroesophageal reflux disease on long-term proton pump inhibitor therapy should be monitored for hypomagnesemia. Factors such as total protein content, hormones, and total body volume status can biochemically influence electrolyte levels.
Hypomagnesemia can lead to hypocalcemia due to its effects on parathyroid hormone activity. Intravenous insulin administration is associated with a spurious decrease in potassium levels as insulin shifts potassium intracellularly.
Therefore, a patient with hypoalbuminemia, as seen in liver cirrhosis or nephrotic syndrome, will demonstrate artificially abnormal serum calcium levels. Hyponatremia, hypernatremia, and hypomagnesemia can lead to neurological consequences such as seizures.
Hypokalemia and hyperkalemia, as well as hypocalcemia, may cause cardiac arrhythmias. Some consequences of potassium, calcium, and magnesium abnormalities are fatigue, lethargy, and muscle weakness.
Patients should be counseled to take all medications exactly as prescribed to avoid any potential adverse effect of electrolyte imbalance. They should also call for immediate medical help if experiencing generalized weakness, muscle aches, or altered mental status.

Introduction Electrolytes are essential for basic life functioning, such as maintaining electrical neutrality in cells and generating and conducting action potentials in the nerves and muscles.
Sodium Sodium, an osmotically active cation, is one of the essential electrolytes in the extracellular fluid. Phosphorus Phosphorus is an extracellular fluid cation. Specimen Collection A blood specimen for electrolytes uses lithium heparin tubes, plus the standard phlebotomy equipment and personnel, as with any blood draw.
Procedures Blood is collected in lithium heparin tubes and then goes to the laboratory to evaluate serum electrolytes. Indications Indications to order serum electrolyte panels are numerous.
Some indications are: Routine blood investigations. Routine monitoring of hospitalized patients on medications, receiving fluid therapy, undergoing dietary changes, or being treated for ongoing illnesses. Any illness that can cause electrolyte derangements, such as malnutrition, gastrointestinal disorders, cardiac disorders, kidney dysfunction, endocrine disorders, circulatory disorders, lung disorders, and acid-base imbalance [19].
Potential Diagnosis Measurement of electrolytes will help clinicians in the diagnosis of a medical condition, the effectiveness of treatment, and the potential side effect of medications. Examples include: A patient with heart failure receiving diuretics needs a workup for sodium, potassium, bicarbonate, and magnesium, as diuretics can exert adverse effects on electrolyte balance.
Interfering Factors Factors such as total protein content, hormones, and total body volume status can biochemically influence electrolyte levels.
Complications Hyponatremia, hypernatremia, and hypomagnesemia can lead to neurological consequences such as seizures.
Patient Safety and Education Patients should be counseled to take all medications exactly as prescribed to avoid any potential adverse effect of electrolyte imbalance. Clinical Significance Some of the common causes of electrolyte disorders seen in clinical practices are: Hyponatremia: low dietary sodium intake, primary polydipsia, syndrome of inappropriate antidiuretic hormone secretion SIADH , heart failure, cirrhosis, adrenal insufficiency, prolonged hyperglycemia, and severe dyslipidemia.
Hypernatremia: unreplaced fluid loss via the skin or gastrointestinal tract, osmotic diuresis, or hypertonic saline administration. Hyperkalemia: metabolic acidosis, insulin deficiency, hypoaldosteronism, prolonged beta-blocker use, or acute or chronic kidney disease.
Hypercalcemia: malignancy, hyperparathyroidism, or chronic granulomatous diseases such as tuberculosis or sarcoidosis. Hypocalcemia: acute pancreatitis, iatrogenic parathyroid dysfunction, resistance to parathyroid hormone, hypomagnesemia, or sepsis.
Hypomagnesemia: increased renal losses with diuretics, alcohol use disorder, or gastrointestinal losses. Bicarbonate level: increases in primary metabolic alkalosis or compensation to primary respiratory acidosis and decreases in primary metabolic acidosis or compensation to primary respiratory alkalosis.
Hypophosphatemia: refeeding syndrome, vitamin D deficiency, or hyperparathyroidism. Review Questions Access free multiple choice questions on this topic.

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. 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. People feel thirsty, and as dehydration read more or overhydrated Overhydration Overhydration is an excess of water in the body. read more.
