What is dehydration? What are the symptoms of dehydration in the human body

A state of extreme lack of water in the body is called dehydration. There are two main types: hydration-deficient dehydration (caused by insufficient water intake) and salt-deficient dehydration (caused by severe vomiting and diarrhoea) in which minerals (mainly sodium) are more deficient than hydration.

In addition, when sweating, along with water, minerals, especially salts, are lost. Therefore, dehydration due to sweating is a mixed type of dehydration in which both water and salt are lost.

Dehydration refers to a symptom of metabolic disorders caused by the human body consuming a large amount of water due to lesions, and even life-threatening, and it is necessary to rely on infusion to replenish body fluids. A group of clinical symptoms caused by a decrease in extracellular fluid is divided into hypotonic dehydration according to the accompanying changes in serum sodium or osmolality, that is, a decrease in extracellular fluid combined with hyponatremia; Hyperosmolar dehydration, i.e., decreased extracellular fluid with high blood sodium; Isotonic dehydration is a decrease in extracellular fluid with normal serum sodium.

Principles of prevention and control. 1. The primary disease should be prevented and the action of certain causes should be prevented. In hyperosmolar dehydration, a 5% dextrose solution should be given because of the high sodium concentration in the blood. Severe hypernatremia can be given intravenously or 3% dextrose solution.

2 It should be noted that in hyperosmolar dehydration, the serum sodium concentration is high, but the patient still has sodium loss, so a certain amount of sodium-containing solution should also be supplemented to avoid extracellular fluid hypotonic.

Dehydration is a decrease in the volume of body fluids, or an imbalance in the distribution of body fluids in various parts of the body, resulting in a decrease in effective circulation. Clinically, multi-system symptoms such as poor elasticity, sunken eyes, nausea, vomiting, decreased urine output, fatigue, dizziness, and even coma may occur, which often need to be corrected by blood volume and electrolyte supplementation.

Vegetable dehydration is the process of removing fresh vegetables containing water so that the vegetables can be stored for a long time.

Problems to be paid attention to in the process of vegetable dehydration.

1. Depending on the type of vegetable, the dehydration treatment process used is also different.

2. Some vegetables (such as broccoli) will greatly lose their nutrients if they are dried at high temperature, so the temperature should not exceed 60 degrees Celsius during the drying process (Shenyang Yuanda Technology Patent: Drying Temperature Control Device).

3. Vegetable dehydration should be completed in a short period of time, and it will affect its quality and nutrients for a long time.

Are you talking about dehydration in the medical sense?

Dehydration in medicine refers to the loss of water and electrolytes in the body to varying degrees due to various reasons, accompanied by acid-base balance disorders, and even life-threatening. Dehydration is hypertonic dehydration, isotonic dehydration, and hypotonic dehydration.

It is the separation of water from a substance.

Test: How do you dehydrate on laundry, how do you wash clothes, take water to dry clothes, if the human body is dehydrated? That's according to this sweat you sweat too much, so it leads to dehydration.

1. Slight: dry mucous membrane, slight thirst, normal pulse rate, dark yellow urine.

2. Moderate: the mucous membrane is quite dry, thirsty, the pulse rate is rapid but weak, and the urine is dark yellow.

3. Severe: the mucous membrane is quite dry, thirsty, lethargic, pulse rate is rapid but weak, shortness of breath, no urine and tears, shock, **pallor.

In addition to the symptoms mentioned on the Internet, there may be a decrease in the brain's decision-making ability and reduced ability to distinguish after dehydration, and the decision that is usually certain will also feel uncertain at this time.
