Dehydration is a condition that happens when the loss of body fluids surpasses the amount of fluids taken in. In dehydration, more water moves out of our cells and bodies than what we take in through drinking.

Causes of Dehydration in Adults

Few of the conditions which can cause rapid and continued loss of fluid, and thus dehydration, are as follows:

  • Vomiting, diarrhoea and excessive urination due to any infection.
  • Unsafe drinking-water.
  • Fever, heat exposure and too much of exercise.
  • An impaired ability to drink (such as coma).
  • Significant injuries to skin such as burns, mouth sores, or any severe skin disease in which water is lost through damaged skin.

Symptoms of Dehydration in Adults

  • Few of the symptoms of dehydration in adults are as follows:
  • Dry mouth
  • Swollen tongue
  • Fatigue
  • Increased thirst
  • Dizziness
  • Fainting
  • Inability to sweat
  • Decreased urine output
  • Confusion
  • Palpitations

NOTE: if urine is concentrated and of deep yellow or amber colour, then it may indicate dehydration

Treatments of Dehydration in Adults


The people who are dehydrated can take in fluids in the following ways:

  • Drinking carbohydrate/ electrolyte-containing drinks.
  • Sucking on ice chips
  • Sipping through a straw.
  • Sipping small amounts of water.

If the person has an elevated temperature or if there has been heat exposure then try to cool him/ her in the following ways:

  • Air-conditioned areas are best for returning body temperature to normal.
  • If air-conditioning is not available, place the person near fans or in the shade.
  • Avoid exposure to excessive cold such as ice packs or ice water.
  • Remove any excess of clothing.

Medical treatment

Medical treatment includes restoring blood volume and then body fluids along with determining the cause of the dehydration
