Regulation of Water Output Obligatory water losses include: Insensible water losses from lungs and skin Water that accompanies undigested food residues in feces Obligatory water loss reflects the fact that: Kidneys excrete mOsm of solutes to maintain blood homeostasis Urine solutes must be flushed out of the body in water Primary Regulatory Hormones 1.

Antidiuretic hormone ADH also called vasopressin Is a hormone made by the hypothalamus, and stored and released in the posterior pituitary gland Primary function of ADH is to decrease the amount of water lost at the kidneys conserve water , which reduces the concentration of electrolytes ADH also causes the constriction of peripheral blood vessels, which helps to increase blood pressure ADH is released in response to such stimuli as a rise in the concentration of electrolytes in the blood or a fall in blood volume or pressure.

These stimuli occur when a person sweats excessively or is dehydrated. Sweating or dehydration increases the blood osmotic pressure. The increase in osmotic pressure is detected by osmoreceptors within the hypothalamus that constantly monitor the osmolarity "saltiness" of the blood 3.

ADH travels through the bloodstream to its target organs : a. Sodium balance. The thyroid gland releases calcitonin CT. CT binds to receptors on osteoblasts bone-forming cells. This triggers the osteoblasts to deposit calcium salts into bone throughout the skeletal system.

This causes the blood calcium levels to fall. CT stops being produced when blood calcium levels return to normal. When blood calcium levels fall, the parathyroid glands located on posterior surface of the thyroid gland release PTH. PTH binds to receptors on osteoclasts bone-degrading cells within the skeletal system The osteoclasts decompose bone and release calcium into the blood.

The blood calcium level rises PTH stops being produced when blood calcium levels return to normal. Normal pH of body fluids: Arterial blood is 7.

Challenges to acid-base balance due to cellular metabolism: produces acids — hydrogen ion donors Acidosis physiological acidosis is a blood pH below 7.

Its principal effect is depression of the central nervous system by depressing synaptic transmissions Alkalosis is a blood pH above 7.

The volume of water in your body will continue to decrease as you age. Fluid in your body contains things such as cells, proteins, glucose, and electrolytes. Electrolytes come from the food and liquids you consume. Salt, potassium, calcium, and chloride are examples of electrolytes.

Electrolytes take on a positive or negative charge when they dissolve in your body fluid. This enables them to conduct electricity and move electrical charges or signals throughout your body. These charges are crucial to many functions that keep you alive, including the operation of your brain, nerves, and muscles, and the creation of new tissue.

Each electrolyte plays a specific role in your body. The following are some of the most important electrolytes and their primary functions:. Fluids are found inside and outside the cells of your body. The levels of these fluids should be fairly consistent. On average , about 40 percent of your body weight is from fluids inside the cells and 20 percent of your body weight is from fluids outside the cells.

Electrolytes help your body juggle these values in order to maintain a healthy balance inside and outside your cells. Sometimes, though, your electrolyte levels can become imbalanced. This can result in your body creating too many or not enough minerals or electrolytes.

A number of things can cause an electrolyte imbalance, including:. Serious emergencies from electrolyte imbalances are rare.

Symptoms of electrolyte imbalance vary depending on which electrolytes are most affected. Common symptoms include:. Treatment options normally include either increasing or decreasing fluid intake. Mineral supplements may be given by mouth or intravenously if depleted.

This article reviews the basic physiology of electrolytes and their abnormalities, and the consequences of electrolyte imbalance. Sodium, an osmotically active cation, is one of the essential electrolytes in the extracellular fluid.

It is responsible for maintaining the extracellular fluid volume and regulating the membrane potential of cells. Sodium is exchanged along with potassium across cell membranes as part of active transport. Sodium regulation occurs in the kidneys. The proximal tubule is where the majority of sodium reabsorption takes place.

In the distal convoluted tubule, sodium undergoes reabsorption. Sodium transport occurs via sodium-chloride symporters, controlled by the hormone aldosterone.

Among the electrolyte disorders, hyponatremia is the most frequent. Hyponatremia has neurological manifestations. Symptoms of hypernatremia include tachypnea, sleeping difficulty, and restlessness.

Rapid sodium corrections can have severe consequences like cerebral edema and osmotic demyelination syndrome ODS. Other factors like chronic alcohol misuse disorder and malnutrition also play a role in the development of ODS.

Potassium is mainly an intracellular ion. The sodium-potassium adenosine triphosphatase pump is primarily responsible for regulating the homeostasis between sodium and potassium, which pumps out sodium in exchange for potassium, which moves into the cells.

In the kidneys, the filtration of potassium takes place at the glomerulus. Potassium reabsorption occurs at the proximal convoluted tubule and thick ascending loop of Henle. Aldosterone increases potassium secretion.

Potassium derangements may result in cardiac arrhythmias. Hypokalemia occurs when serum potassium levels are under 3. The features of hypokalemia include weakness, fatigue, and muscle twitching.

Hypokalemic paralysis is generalized body weakness that can be either familial or sporadic. Muscle cramps, muscle weakness, rhabdomyolysis, and myoglobinuria may be presenting signs and symptoms of hyperkalemia.

Calcium has a significant physiological role in the body. It is involved in skeletal mineralization, contraction of muscles, the transmission of nerve impulses, blood clotting, and secretion of hormones.

The diet is the predominant source of calcium. Calcium is a predominately extracellular cation. Calcium absorption in the intestine is primarily controlled by the hormonally active form of vitamin D, which is 1,dihydroxy vitamin D3. 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.
