How Does Dehydration Affect the Body ?

Dehydration is a condition, seen at any time of the year but more often during the warmer months,  whereby the body doesn’t have enough water and therefore is unable to function properly. The severity of dehydration, mild, moderate or severe indicates how much water is missing from the body. Severe dehydration can lead to the body going into shock. The people who are most susceptible to dehydration are people who work outdoors in warm weather, and also athletes, the elderly, and people who live in high altitudes.

The body loses water in various ways. These include:

  • Sweating
  • Urinating
  • Breathing,
  • Crying
  • Pooping

We can lose an even greater amount of water when we have a fever, diarrhea, vomiting, sweating heavily while exercising strenuously, frequently urinating due to diabetes or when taking certain medications that cause us to deplete the water in our bodies.

What are the symptoms of dehydration? Depending on the severity, in adults they can include:

  • Headaches
  • Dizziness
  • Weakness
  • Muscle cramps
  • Low blood pressure
  • Dark urine
  • Dry skin
  • Rapid heartbeat
  • Rapid breathing
  • Sleepiness

In young children symptoms of dehydration can also include having a dry diaper for several hours, crying without tears, sunken eyes, irritability, and a dry mouth and tongue.

The recommended amount of water taken in every day for an adult woman is 92 fluid ounces and for an adult man it is 124 fluid ounces. More water may be necessary if exercising strenuously or spending time in a very warm environment for an extended period of time. It is recommended that people who are dehydrated avoid caffeinated beverages, sugary drinks, and drinks containing alcohol.

If a person is suspected of being dehydrated, medical exams can help to diagnose it. This will include a thorough history, blood pressure, heart rate, blood test, and urine exams. A simple way to rehydrate some people is to have them drink more water during the day, and in some cases a sports drink that contains electrolytes. A young child may be given called Pedialyte. In more severe cases it may be necessary to give fluids intravenously.
