- What is a medical definition of dehydration? Dehydration [from Latin de- = removal; Greek hydros = water] is a lack of water in the body that results in at least 1% loss of body weight [1,2]; a smaller loss is considered a normal fluctuation of the body water. Synonyms for dehydration are hypohydration and water deficiency.

dehydration 1 excessive loss of water from body tissues. Dehydration is accompanied by a disturbance in the balance of essential electrolytes, particularly sodium, potassium, and chloride. It may follow prolonged fever, diarrhea, vomiting, acidosis, and any condition in which there is rapid depletion of body fluids.

Dog Dehydration Dehydration is a condition that occurs when the water in the dog's body is less than normal. More than 90 percent of a dog's weight is made up of water. Only a 10-percent loss of body fluid can cause the dog to be extremely ill from dehydration.

- Dehydration in adults. Dehydration happens when more fluid is lost by the body than is replaced by drinking liquids. The risk of dehydration increases in hot weather and because of severe vomiting or diarrhoea. Symptoms of dehydration can range from mild to life threatening.

Dehydration Dehydration is usually caused by not drinking enough fluid to replace what we lose. The climate, the amount of physical exercise you are doing (particularly in hot weather) and your diet can contribute to dehydration. You can also become dehydrated as a result of an illness, such as persistent vomiting and diarrhoea, or sweating from a fever. Read more about the causes of dehydration.

Water intoxication Water intoxication. Not to be confused with Hydrocephalus. Water intoxication, also known as water poisoning or hyperhydration, is a potentially fatal disturbance in brain functions that results when the normal balance of electrolytes in the body is pushed outside safe limits by overhydration.

Dehydration in Children Dehydration in Children Overview. Dehydration means that a child's body lacks enough fluid. Dehydration can result from vomiting, diarrhea, not drinking enough fluids, or any combination of these conditions. Rarely, sweating too much or urinating too much can cause dehydration.

- Diarrhea, also spelled diarrhoea, is the condition of having at least three loose or liquid bowel movements each day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and changes in personality.

Dehydration Dehydration occurs when a person does not take in enough fluid or loses too much fluid and cannot replace it. Every cell and organ depends on water, and without it the human body cannot function properly. Although it is possible to go for a long time without food, people cannot live without water for more than a few days.

What is Hydration? - Definition, Facts & Benefits In order to get your body back to its normal state, you had to go through the process of replacing the missing water or hydration. One way to know that you are no longer dehydrated, is that the signs of dehydration will disappear rather promptly.

Definition of Dehydration Reaction By Anne Marie Helmenstine, Ph.D. Dehydration Reaction Definition: A dehydration reaction is a chemical reaction between two compounds where one of the products is water or ammonia. Also Known As: condensation reaction.Examples: Reactions that produce acid anhydrides are dehydration reactions.For example: acetic acid (CH 3 COOH) forms acetic anhydride ((CH 3 CO) 2 O) and water by the dehydration reaction. 2 CH 3 COOH → (CH 3 CO) 2 O + H 2 O.lso Known As: condensation reaction.

- Dehydration occurs when water loss exceeds water intake, usually due to exercise or disease. Most people can tolerate a three to four percent decrease in body water without difficulty.he symptoms of dehydration become increasingly severe with greater water loss. Heart and respiration rates begin to increase to compensate for decreased plasma volume and blood pressure, while body temperature may rise because of decreased sweating.

- Hypotonic dehydration refers to solute loss, and thus loss of intravascular volume, but in the presence of exaggerated intravascular volume depletion for a given amount of total body water gain.

What are the symptoms of dehydration? Dehydration symptoms vary depending on the severity. Mild symptoms are by far the most common and may include thirst, headache, fatigue, decreased urine output and lightheadedness. More severe dehydration may cause dry skin with poor elasticity, fast heartbeat and shortness of breath. Very severe dehydration may cause confusion, unconsciousness and even death.

Dehydration What Is Dehydration: Dehydration is an excessive loss of body fluids. It occurs when the output of fluid exceeds fluid intake. Side effects of treatment such as vomiting or diarrhea can lead to chemotherapy dehydration. Infections, high fever, bleeding, or even something as simple as not drinking enough fluids can also lead to dehydration.

Dehydration Synthesis Dehydration Synthesis is the covalent joining of two compounds via the removal of one water molecule between them, an - H from one and an - OH: from the other. Protein, nucleic acid, and carbohydrate polymers as well as fats are all assembled (polymerized) via a series of dehydration synthesis reactions, which also can be described as condensation reactions or condensation polymerization.

Definition of Dehydration synthesis In chemistry and the biological sciences, a dehydration reaction is usually defined as a chemical reaction that involves the loss of a water molecule from the reacting molecule.

- hy·dra·tion. 1. Chemically, the addition of water; differentiated from hydrolysis, where the union with water is accompanied by a splitting of the original molecule and the water molecule. See also: solvation. 2. Clinically, the taking in of water; used commonly in the sense of reduced hydration or dehydration.

Dehydration Synthesis: Definition, Reaction & Examples Dehydration synthesis is classified as a type of chemical reaction. A chemical reaction is the process where chemical substances (called reactants) transform into new substances (called products). But a dehydration synthesis also has a different alias it can go by; this is a condensation reaction.

Dehydration Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. If you don't replace lost fluids, you will get dehydrated. Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults. The most common cause of dehydration in young children is severe diarrhea and vomiting. Older adults naturally have a lower volume of water in their bodies, and may have conditions or take medications that increase the risk of dehydration.

Dehydration Dehydration occurs when the body loses more water than it takes in. Vomiting, diarrhea, the use of drugs that increase urine excretion (diuretics), profuse sweating (for example, during heat waves, particularly with prolonged exertion), and decreased water intake can lead to dehydration.

- Dehydration is the loss of water and salts from the body. The human body needs water to maintain enough blood and other fluids to function properly. Along with the fluids, the body also needs electrolytes, which are salts normally found in blood, other fluids, and cells. from the lungs during normal breathing.
