Treatment processes also lead to the presence of some minerals. Examples include calcium , zinc , manganese , phosphate , fluoride and sodium compounds. There are a variety of trace elements present in virtually all potable water, some of which play a role in metabolism.

For example, sodium , potassium and chloride are common chemicals found in small amounts in most waters, and these elements play a role in body metabolism. Other elements such as fluoride, while arguably beneficial in low concentrations, can cause dental problems and other issues when present at high levels.

Water is essential for the growth and maintenance of our bodies, as it is involved in a number of biological processes. When a person is ill, fluid may also be lost through vomiting , diarrhea , and hemorrhage. 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.

Overview of acid-base and electrolyte disorders

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. Common causes of low magnesium include alcoholism and its associated malnutrition, chronic diarrhea , and medications like diuretics water pills used to control high blood pressure.

More than half of hospitalized patients in ICUs may become magnesium deficient. Symptoms involve the heart with rhythm abnormalities, muscles with weakness and cramps, and the nervous system , potentially causing confusion, hallucinations, and seizures. Hypermagnesemia describes too much magnesium in the bloodstream and most often occurs in patients with kidney function problems in which the excretion of magnesium is limited.

Fluid and Electrolytes

In these patients, too much magnesium intake in the diet or from magnesium-containing medications like milk of magnesia or Maalox may cause elevated magnesium levels. Since the absorption and excretion of magnesium are linked to other electrolytes, other diseases may be associated with high magnesium levels, including diabetic ketoacidosis, adrenal insufficiency, and hyperparathyroidism. Hypermagnesemia is often associated with hypocalcemia low calcium and hyperkalemia high potassium.

Symptoms can include heart rhythm disturbances, muscle weakness, nausea and vomiting, and breathing difficulties. This electrolyte is an important component of the equation that keeps the acid-base status of the body in balance. The lungs regulate the amount of carbon dioxide, and the kidneys regulate bicarbonate HCO3.

This electrolyte helps buffer the acids that build up in the body as normal byproducts of metabolism.

For example, when muscles are working, they produce lactic acid as a byproduct of energy formation. HCO3 is required to be available to bind the hydrogen released from the acid to form carbon dioxide and water. When the body malfunctions, too much acid may also be produced for example, diabetic ketoacidosis, renal tubular acidosis and HCO3 is needed to try to compensate for the extra acid production.

Measuring the amount of bicarbonate in the blood stream can help the health care practitioner decide how severe the acid-base balance of the body has become. Readers Comments 4 Share Your Story.

Electrolytes - Experience What conditions have you experienced from having too many or too few electrolytes? The results can tell if your levels are good or if they are out of balance. This will help your doctor figure out where to look for the condition or medication that might be causing your imbalance. If your doctor is concerned about the health of your heart or kidneys , a chloride test can help explain what might be wrong. Your chloride levels can drop if you have had bouts of vomiting or diarrhea. Diabetes can sometimes cause chloride levels to increase. The amount of fluids you drink before the test may affect the results, so ask your doctor whether you should change anything about your fluid intake.

Vomiting or diarrhea in the days before the test may lead to a lower chloride result. You should also tell your doctor all the prescription and over-the-counter medications you take, as well as any vitamins or supplements.

You may not need to change your medication routine. Chloride levels also can be checked with a urine test.
