The main electrolytes in your body include: Bicarbonate, which helps maintain the body's acid and base balance pH.
It also plays an important role in moving carbon dioxide through the bloodstream. Calciumwhich helps make and keep bones and teeth strong. Chloride, which also helps control the amount of fluid in the body.
In addition, it helps maintain healthy blood volume and blood pressure. Magnesium, which helps your muscles, nerves, and heart work properly. It also helps control blood pressure and blood glucose blood sugar. Phosphate, which works together with calcium to build strong bones and teeth.
Potassiumwhich helps your cells, heart, and muscles work properly. Sodiumwhich helps control the amount of fluid in the body. It also helps your nerves and muscles work properly.
You get these electrolytes from the foods you eat and the fluids you drink. What is an electrolyte imbalance? The names of the different types of electrolyte imbalances are: Electrolyte Too low Too high Bicarbonate Acidosis Alkalosis Calcium Hypocalcemia Hypercalcemia Chloride Hypochloremia Hyperchloremia Magnesium Hypomagnesemia Hypermagnesemia Phosphate Hypophosphatemia Hyperphosphatemia Potassium Hypokalemia Hyperkalemia Sodium Hyponatremia Hypernatremia How are electrolyte imbalances diagnosed?
What are the treatments for electrolyte imbalances? For example: If you don't have enough of an electrolyte, you may get electrolyte replacement therapy. This involves giving you more of that electrolyte.
It could be a medicine or supplement that you swallow or drink, or it may be given intravenously by IV. If you have too much of an electrolyte, your provider may give you medicines or fluids by mouth or by IV to help remove that electrolyte from your body.
In severe cases, you may need dialysis to filter out the electrolyte. Start Here. Also in Spanish. Diagnosis and Tests.

| Body Fluids | Vomiting, diarrhea, excessive sweating, burns, kidney failure, and use of diuretics may cause dehydration. People feel thirsty, and as dehydration read more , the development of kidney stones Stones in the Urinary Tract Stones calculi are hard masses that form in the urinary tract and may cause pain, bleeding, or an infection or block of the flow of urine. Tiny stones may cause no symptoms, but larger stones read more , and other medical problems—healthy adults should drink at least 1½ to 2 quarts about 2 liters of fluids a day. Drinking too much is usually better than drinking too little, because excreting excess water is much easier for the body than conserving water. However, when the kidneys are functioning normally, the body can handle wide variations in fluid intake. The body obtains water primarily by absorbing it from the digestive tract. Additionally, a small amount of water is produced when the body processes metabolizes certain nutrients. The body loses water primarily by excreting it in urine from the kidneys. Depending on the body's needs, the kidneys may excrete less than a pint or up to several gallons about half a liter to over 10 liters of urine a day. About 1½ pints a little less than a liter of water are lost daily when water evaporates from the skin and is breathed out by the lungs. Profuse sweating—which may be caused by vigorous exercise, hot weather, or a high body temperature—can dramatically increase the amount of water lost through evaporation. Normally, little water is lost from the digestive tract. However, prolonged vomiting or severe diarrhea can result in the loss of a gallon or more a day. Usually, people can drink enough fluids to compensate for excess water loss. However, people who have severe vomiting Nausea and Vomiting in Adults Nausea is an unpleasant feeling of needing to vomit. People also may feel dizziness, vague discomfort in the abdomen, and an unwillingness to eat. Vomiting is a forceful contraction of the stomach read more or diarrhea Diarrhea in Adults Diarrhea is an increase in the volume, wateriness, or frequency of bowel movements. See also Diarrhea in Children. The frequency of bowel movements alone is not the defining feature of diarrhea An individual is at an increased risk of dehydration in these instances, as the kidneys will find it more difficult to match fluid loss by reducing urine output the kidneys must produce at least some urine in order to excrete metabolic waste. Oral rehydration therapy ORT , is type of fluid replacement used as a treatment for dehydration. In an acute hospital setting, fluid balance is monitored carefully. This provides information on the patient's state of hydration, kidney function and cardiovascular function. If blood pressure is low hypotension , the filtration rate in the kidneys will lessen, causing less fluid reabsorption and thus less urine output. An accurate measure of fluid balance is therefore an important diagnostic tool, and allows for prompt intervention to correct the imbalance. Fluid can leave the body in many ways. Fluid can enter the body as preformed water, ingested food and drink and to a lesser extent as metabolic water which is produced as a by-product of aerobic respiration cellular respiration and dehydration synthesis. A constant supply is needed to replenish the fluids lost through normal physiological activities, such as respiration, sweating and urination. Water generated from the biochemical metabolism of nutrients provides a significant proportion of the daily water requirements for some arthropods and desert animals, but provides only a small fraction of a human's necessary intake. Input of water is regulated mainly through ingested fluids, which, in turn, depends on thirst. An insufficiency of water results in an increased osmolarity in the extracellular fluid. This is sensed by osmoreceptors in the organum vasculosum of the lamina terminalis , which trigger thirst. Thirst can to some degree be voluntarily resisted, as during fluid restriction. The human kidneys will normally adjust to varying levels of water intake. The kidneys will require time to adjust to the new water intake level. This can cause someone who drinks a lot of water to become dehydrated more easily than someone who routinely drinks less. The body's homeostatic control mechanisms, which maintain a constant internal environment, ensure that a balance between fluid gain and fluid loss is maintained. The anti-diuretic hormones vasopressin ADH and aldosterone play a major role in this. If the body is becoming fluid- deficient , this will be sensed by osmoreceptors in the vascular organ of lamina terminalis and subfornical organ. Thus, there will be an increase in the secretion of antidiuretic hormone, causing fluid to be retained by the kidneys and urine output to be reduced. A fluid-insufficiency causes a decreased perfusion of the juxtaglomerular apparatus in the kidneys. This activates the renin—angiotensin system. Among other actions, it causes renal tubules i. the distal convoluted tubules and the cortical collecting ducts to reabsorb more sodium and water from the urine. Potassium is secreted into the tubule in exchange for the sodium, which is reabsorbed. The activated renin—angiotensin system stimulates the zona glomerulosa of the adrenal cortex which in turn secretes the hormone aldosterone. This hormone stimulates the reabsorption of sodium ions from distal tubules and collecting ducts. Water in the tubular lumen cannot follow the sodium reabsorption osmotically, as this part of the kidney is impermeable to water; release of ADH vasopressin is required to increase expression of aquaporin channels in the cortical collecting duct, allowing reabsorption of water. Fasting is the abstention from eating and sometimes drinking. From a purely physiological context, "fasting" may refer to the metabolic status of a person who has not eaten overnight see " Breakfast " , or to the metabolic state achieved after complete digestion and absorption of a meal.

Aspect of homeostasis concerning control of the amount of water in an organism. Not to be confused with Water balance. The person should and normally does respond by drinking water. The hypothalamus of a dehydrated person also releases antidiuretic hormone ADH through the posterior pituitary gland. ADH signals the kidneys to recover water from urine, effectively diluting the blood plasma. To conserve water, the hypothalamus of a dehydrated person also sends signals via the sympathetic nervous system to the salivary glands in the mouth. The signals result in a decrease in watery, serous output and an increase in stickier, thicker mucus output. Decreased blood volume resulting from water loss has two additional effects. First, baroreceptors, blood-pressure receptors in the arch of the aorta and the carotid arteries in the neck, detect a decrease in blood pressure that results from decreased blood volume. Second, the kidneys have a renin-angiotensin hormonal system that increases the production of the active form of the hormone angiotensin II, which helps stimulate thirst, but also stimulates the release of the hormone aldosterone from the adrenal glands. Aldosterone increases the reabsorption of sodium in the distal tubules of the nephrons in the kidneys, and water follows this reabsorbed sodium back into the blood. Circulating angiotensin II can also stimulate the hypothalamus to release ADH. A person who repeatedly vomits or who has diarrhea may become dehydrated, and infants, because their body mass is so low, can become dangerously dehydrated very quickly. Endurance athletes such as distance runners often become dehydrated during long races. Dehydration can be a medical emergency, and a dehydrated person may lose consciousness, become comatose, or die, if his or her body is not rehydrated quickly. Water loss from the body occurs predominantly through the renal system. A person produces an average of 1. Although the volume of urine varies in response to hydration levels, there is a minimum volume of urine production required for proper bodily functions. The kidney excretes to milliosmoles of solutes per day to rid the body of a variety of excess salts and other water-soluble chemical wastes, most notably creatinine, urea, and uric acid. Failure to produce the minimum volume of urine means that metabolic wastes cannot be effectively removed from the body, a situation that can impair organ function. The minimum level of urine production necessary to maintain normal function is about 0. The kidneys also must make adjustments in the event of ingestion of too much fluid. Diuresis , which is the production of urine in excess of normal levels, begins about 30 minutes after drinking a large quantity of fluid. Diuresis reaches a peak after about 1 hour, and normal urine production is reestablished after about 3 hours. Antidiuretic hormone ADH , also known as vasopressin, controls the amount of water reabsorbed from the collecting ducts and tubules in the kidney. |
Body fluid balance -
One way the the kidneys can directly control the volume of bodily fluids is by the amount of water excreted in the urine. Either the kidneys can conserve water by producing urine that is concentrated relative to plasma, or they can rid the body of excess water by producing urine that is dilute relative to plasma.
Direct control of water excretion in the kidneys is exercised by vasopressin, or anti-diuretic hormone ADH , a peptide hormone secreted by the hypothalamus. ADH causes the insertion of water channels into the membranes of cells lining the collecting ducts, allowing water reabsorption to occur.
Without ADH, little water is reabsorbed in the collecting ducts and dilute urine is excreted. ADH secretion is influenced by several factors note that anything that stimulates ADH secretion also stimulates thirst :. By special receptors in the hypothalamus that are sensitive to increasing plasma osmolarity when the plasma gets too concentrated.
These stimulate ADH secretion. By stretch receptors in the atria of the heart, which are activated by a larger than normal volume of blood returning to the heart from the veins.
These inhibit ADH secretion, because the body wants to rid itself of the excess fluid volume. By stretch receptors in the aorta and carotid arteries, which are stimulated when blood pressure falls. These stimulate ADH secretion, because the body wants to maintain enough volume to generate the blood pressure necessary to deliver blood to the tissues.
In addition to regulating total volume, the osmolarity the amount of solute per unit volume of bodily fluids is also tightly regulated. Extreme variation in osmolarity causes cells to shrink or swell, damaging or destroying cellular structure and disrupting normal cellular function.
Regulation of osmolarity is achieved by balancing the intake and excretion of sodium with that of water. Sodium is by far the major solute in extracellular fluids, so it effectively determines the osmolarity of extracellular fluids.
An important concept is that regulation of osmolarity must be integrated with regulation of volume, because changes in water volume alone have diluting or concentrating effects on the bodily fluids. For example, when you become dehydrated you lose proportionately more water than solute sodium , so the osmolarity of your bodily fluids increases.
In this situation the body must conserve water but not sodium, thus stemming the rise in osmolarity. If you lose a large amount of blood from trauma or surgery, however, your loses of sodium and water are proportionate to the composition of bodily fluids.
In this situation the body should conserve both water and sodium. They must be alert, fluids must be accessible, and the person must be strong enough to reach for fluids. When a person is unable to respond to thirst signals, dehydration occurs.
Older individuals are at increased risk of dehydration due to age-related impairment in thirst perception. The average adult intake of fluids is about 2, mL per day from both food and drink. An increased amount of fluids is needed if the patient has other medical conditions causing excessive fluid loss, such as sweating, fever, vomiting, diarrhea, and bleeding.
The Renin-Angiotensin-Aldosterone System RAAS plays an important role in regulating fluid output and blood pressure. When there is decreased blood pressure which can be caused by fluid loss , specialized kidney cells make and secrete renin into the bloodstream.
Renin acts on angiotensinogen released by the liver and converts it to angiotensin I, which is then converted to angiotensin II. Angiotensin II does a few important things.
First, angiotensin II causes vasoconstriction to increase blood flow to vital organs. It also stimulates the adrenal cortex to release aldosterone. Aldosterone is a steroid hormone that triggers increased sodium reabsorption by the kidneys and subsequent increased serum osmolality in the bloodstream.
As you recall, increased serum osmolality causes osmosis to move fluid into the intravascular compartment in an effort to equalize solute particles. Fluid output occurs mostly through the kidneys in the form of urine.
Fluid is also lost through the skin as perspiration, through the gastrointestinal tract in the form of stool, and through the lungs during respiration. Normally, the kidneys produce about 1, mL of urine per day when fluid intake is adequate.
Decreased urine production is an early sign of dehydration or kidney dysfunction. It is important for nurses to assess urine output in patients at risk. Two types of fluid imbalances are excessive fluid volume also referred to as hypervolemia and deficient fluid volume also referred to as hypovolemia.
These imbalances primarily refer to imbalances in the extracellular compartment, but can cause fluid movement in the intracellular compartments based on the sodium level of the blood.
Excessive fluid volume also referred to as hypervolemia occurs when there is increased fluid retained in the intravascular compartment. Patients at risk for developing excessive fluid volume are those with the following conditions:. Symptoms of fluid overload include pitting edema, ascites, and dyspnea and crackles from fluid in the lungs.
Edema is swelling in dependent tissues due to fluid accumulation in the interstitial spaces. Ascites is fluid retained in the abdomen. Treatment depends on the cause of the fluid retention. Sodium and fluids are typically restricted and diuretics are often prescribed to eliminate the excess fluid.
Deficient fluid volume also referred to as hypovolemia or dehydration occurs when loss of fluid is greater than fluid input. Common causes of deficient fluid volume are diarrhea, vomiting, excessive sweating, fever, and poor oral fluid intake. Individuals who have a higher risk of dehydration include the following:.
Dehydration can be mild and treated with increased oral intake such as water or sports drinks. Severe cases can be life-threatening and require the administration of intravenous fluids.
Pressure inside the vascular compartment created by protein content of the blood in the form of albumin that holds water inside the blood vessels. Movement of fluid through a semipermeable membrane from an area of lesser solute concentration to an area of greater solute concentration.
