dehydration of human body

Dehydration - it is not enough fluid in the body, which has a negative effect on his work. Under dehydration or dehydration refers to the insufficient content of the fluid and, accordingly, important salts that negatively affect its functioning. Since the body of an adult is 60% composed of water, its loss and disturbance of water-salt balance is a very serious problem for all but the most dangerous dehydration for children and the elderly.

Overview

The most dangerous and often dehydrated (dehydration, doctors still say) in the summer. When driving in hot climates of the country must be constantly aware of the possibility of developing this condition. But dehydration can occur as a result of various diseases and insufficient intake of fluids in the body.

  • Heavy sweating;
  • Severe diarrhea or vomiting;
  • Increased urine output (diuresis abundant);
  • Insufficient fluid intake, which can be caused by loss of appetite or nausea.

Symptoms of dehydration

Average thirst is already a sign that the body does not have enough fluid and needs to be filled. But the symptoms of dehydration as problems are weakness and headache, which may resemble the one that occurs during a hangover. Also begins dizziness, worsening general health, may become more frequent heart rate, dry mouth occurs. One of the most obvious signs of dehydration is considered darkened urine and a reduction in the frequency of urination. In addition, when there is dehydration, weight loss, sometimes quite serious.

The feeling of thirst is not a normal means of determining dehydration. If you really want to drink, it means that the body is not enough liquid. A better indicator of the level of dehydration is the color and quantity of urine. If urine is dark and a little yellow, it means that the body does not have enough liquid reserves and the need to fill them.

The first signs of dehydration:

  • Intense sweating associated with exercise or heat;
  • A small amount of urine, excessive thirst, dry mouth;
  • dark circles under the eyes;
  • Decrease in activity in children;
  • Fatigue in adults.

If the process progresses, you should seek medical help. More serious signs of dehydration:

  • Confusion;
  • Weakness;
  • Fainting;
  • Low elasticity of the skin (the skin is slowly returning to normal, if it squeeze or pinch).

Complications of dehydration

  • Kidney damage;
  • Shock (paleness, shortness of breath, cold sweats, clammy skin, drowsiness, rapid pulse, rapid but weak pulse, fainting);
  • Dehydration can lead to death (especially in infectious diseases and in debilitated patients or children).

What you can do

You should drink plenty of fluids, with the exception of alcoholic beverages, to take special drugs containing salts (electrolytes) or solutions to recover the amount of fluid in the body (they can be purchased at the pharmacy).

You must consult your doctor immediately if dehydration occurred in an infant or a child under the age of 10 years, as well as in severe uncontrollable vomiting. If there are signs of shock, or call an ambulance to bring the patient to the nearest hospital.

What can a doctor

The physician should determine and correct the cause of dehydration.

In severe stages of dehydration doctor should take you to the hospital for intravenous fluids.

preventive measures

Dehydration is easier to prevent than to treat.

To prevent dehydration sure to drink during the day, regardless of your activity level and your health.

At risk are primarily young children and the elderly, especially with increasing temperature, nausea and diarrhea.

If you are sick, monitor fluid intake, drink more than usual.

In children high temperature sensitivity higher than in adults, therefore it is necessary to make sure that during exercise in hot weather children drink a minimum of 150 g of water every 30 minutes. Adults during strenuous exercise in very hot weather should drink at least a liter of fluid per hour.

The water in the body is inside the cells and outside them, and contains more potassium first and second - more sodium. First and foremost, the body loses it water, which is outside the cell, and hence there are large losses of sodium. To eliminate dehydration, use of sodium-glucose uptake mechanism of body fluids. This phenomenon consists in that, in order to move sodium and water molecule, cells need glucose. This mechanism allows you to cope with dehydration, even in the most difficult cases. For the first time such a formula was developed in the 1960s and, having undergone only minor changes, is still in use, as recommended by organizations such as WHO and UNICEF as the most safe and effective treatment for dehydration.
