What To Do When You Are Dehydrated

What To Do When You Are Dehydrated - What To Do When You Are Dehydrated? . You either come through a low fluid intake or increased fluid loss. The latter can be about due to diarrhea or profuse sweating. The dehydration is usually connected to the salt balance (electrolyte balance). Read here everything important to causes and treatment of dehydration.

Dehydration: Description

The term dehydration (dehydration, dehydration), physicians described a dehydration of the body, so a lack of body water. Trigger is a disorder of the water and salt balance (electrolyte balance). Someone is severely dehydrated, also called pathogen.

There are three types of dehydration: isotonic, hypotonic and hypertonic dehydration. The proportion of body water and sodium – a positively charged particle, which occurs normally in particular outside the body cells (in the extracellular space) and only to a lesser extent within the cells (intracellular space) is crucial for this subdivision.

Isotonic dehydration

Lack of water and sodium to the same extent, the body is called isotonic dehydration. Only the extracellular space is affected by the deficiency. An isotonic dehydration can occur through a massive blood loss.

Hypo tone dehydration

Hypotonic dehydration is characterized by the fact that there are not enough sodium ion in the extracellular space in relation to the existing water – sodium deficiency is therefore greater than the lack of water.

As a result, water from the extracellular space in the cells flows into: the extracellular space is reduced, the cells are above water. Reason can be for example the loss of body fluid (profuse sweating, vomiting, diarrhea, etc.) for a hypotonic dehydration if you only by water with low salt content (such as tea, tap water) to compensate for these attempts.

Hypertonic dehydration

The body loses more water than sodium, developed a hypertonic dehydration. The sodium concentration in the extracellular space is increasing this beyond the normal values. As a result of flowing water from the cells out, which is not sufficient as a replacement and to reduce the concentration of sodium in the extracellular space.

Ultimately a lack of fluid and an increased concentration of sodium exist both outside and within the cells. For example, hypertonic dehydration resulting profuse sweating or diarrhea.

Dehydration: Symptoms vary depending on the severity of A dehydration is different clearly noticeable depending on the extent of:

Mild dehydration is a loss of liquid from three to five percent of their body weight. This manifests itself in thirst, slight dryness of the skin and mucous membranes, as well as a concentrated (clear-colored) urine.

The loss of liquid is six to eight percent of body weight, is a moderate dehydration. Symptoms include sunken eyes, pronounced dryness of the skin and mucous membranes, severely diminished urinary excretion (oliguria) and heart rate (tachycardia).

For severe dehydration, fluid loss makes nine to twelve percent of body weight. This leads to low blood pressure (hypotension) and the folds of skin: to make a skin fold (such as on the back of the hand) with two fingers and then releases this immediately smooths to the fold, but stops a few seconds.

In a 12-to 15-percent loss of fluid, it comes to shock: poor circulation and disorders of consciousness occur, such as lethargy, confusion and delirium up to come.

Dehydration: Causes and possible diseases

There are many possible causes of dehydration, such as:

  • Too small amount of drinking: especially when heavy sweating due to physical effort at high temperatures, the body loses lots of fluids and salts. They cannot replace a dehydration develops. Even older people who drink often far too little due to a diminished sense of thirst and are therefore frequently dehydrated are at risk.
  • Diarrhea and vomiting: Severe diarrhea and severe vomiting – such as a result of a “stomach, intestinal ‘flu (gastroenteritis) – can lead to a drying out of the body when the fluid and salt loss is not compensated.
  • Other infectious diseases: in principle each infectious diseases caused by viruses or bacteria (such as meningitis, pneumonia, etc.) can cause dehydration – by lack of fluid intake and/or strong fluid excretion.
  • Blood loss: large blood loss about can entail a dehydration for injuries and internal bleeding.
  • Burns: The injured skin, the body loses plenty of fluids. For larger Burns is thus the danger of dehydration.
  • Acute renal failure: acute renal failure (sudden loss of kidney function) the urinary excretion is back strongly, which can damage the kidneys. With timely treatment, the kidneys recover completely. In the postnatal phase it may cause, but an increased urinary excretion (polyurische phase) a lack of water in the body.
  • Addison’s disease: This is a severe Hypofunction of the adrenal cortex. In stress situations or under physical stress she can lead to acute Addison crisis – a life-threatening condition, which goes hand in hand with a massive water and salt loss and imminent dehydration.
  • Diabetic coma: this life-threatening complication of diabetes mellitus is characterized by extremely high blood sugar levels. This leads to nausea, vomiting, increased urinary excretion, dehydration and clouding of consciousness (until the coma).
  • Diabetes insipidus: this rare hormonal disorder of the water budget leads to massive urinary excretion and correspondingly strong thirst. The large loss of fluid can cause dehydration.

Therapy with diuretics: Diuretics are draining medications as prescribed for high blood pressure, congestive heart failure and fluid retention in the tissue (edema). However, in too high doses, they can cause dehydration.

Dehydration: When should a doctor?

If you are unsure whether you yourself or a member is dehydrated, or clear signs of dehydration occur, ask a doctor for advice as a precaution. Especially in infants and the elderly a doctor should be consulted on suspected dehydration at an early stage.

The same applies if the patient denied an adequate fluid intake, or other symptoms occur such as strong and persistent diarrhea with or without vomiting or high fever.

Dehydration: how’s the doctor?

The doctor will first of all the medical history in experience bring (history), either in a conversation with the patient or family members. Important information is for example the drinking behavior in the past few days, more illness complaints, (as diarrhea, vomiting, high fever), existing conditions (such as diabetes), as well as, where appropriate, the taking of medications (such as diuretics or laxatives).

During the physical examination signs such as dry skin and mucous membranes, sunken eyes or standing folds of skin the doctor indicating that the patient is dehydrated. Blood and urine tests reveal among other shifts in electrolyte balance (such as low sodium). These are also important information to clarify a dehydration.

The doctor treated a dehydration

Possibly, the doctor with dehydration, will treat the underlying disease or eliminate the triggering factors. In addition, the lost fluid must be replaced in milder cases as a drink, with a severe lack of fluid infusion.

The doctor depending on the form and extent of dehydration a suitable liquid selects, as an isotonic liquid isotonic dehydration or a 5% glucose solution in hypertonic dehydration.

The fluid replacement should be done slowly. A too fast administration of large quantities of liquid or a wrong salinity could cause such as hypertonic dehydration a swelling of the brain (cerebral edema) and/or lung water (pulmonary edema).

Are about high fever due to the gift of fever medicines, except yet more complaints, handled this also drying out if necessary.

Dehydration: You can do that

Mild cases of lack of water through profuse sweating at high temperatures or through a stomach-intestinal flu can often resolve on their own by the individual drinks much, best each in small quantities. As fluid replacement for dehydration as water, fruit or herbal tea and slightly salty broths are suitable.
