Dehydration: Causes, Symptoms, and Risk Factors

Dehydration takes place in one’s body when one loses or uses more fluid than you can take in. Also, if your body is in a state where it doesn’t have enough fluids to carry out normal functions, and the lost fluids aren’t replaced, then you are said to be dehydrated. Dehydration can become fatal especially in kids and the elderly. Dehydration comes in various levels ranging from mild, to moderate and even severe. Mild and moderate dehydration can be controlled through taking enough water while severe dehydration can only be attended to by immediate medical treatment. Let us have a deeper look at dehydration.

What Are The Causes Of Dehydration?

Health Ignorance

Most people ignore the vital use of taking water regularly. Dehydration occurs even under the simplest circumstances such as lack of water intake during exercise, travelling or hiking. Others neglect to take enough water when they are sick, busy or just because it is a cold day. All these funny reasons deplete the amount of fluid in one’s body eventually causing dehydration.

Diarrhoea And Vomiting

Severe diarrhoea and vomiting causes loss of water and electrolytes from the body in the shortest amount of time.


While sweating is normal, a fever comes with excessive sweating that forces the body to lose more water from the body than it should. The higher the fever, the more likely you are to become dehydrated.

Excessive Sweating

During hot and humid weathers, your body tends to lose more water due to excessive sweating. While this is unavoidable, if you do not replace the lost water, you become more vulnerable to dehydration. The same goes to anyone doing a vigorous physical activity without taking water.

Increased Urination

Some undiagnosed and uncontrolled diseases such as diabetes may cause frequent urination which translates into the loss of fluids in the body eventually causing dehydration.

What Are The Symptoms Of Dehydration?

Getting thirsty is a sharp indicator that your body needs some water intake. However, this isn’t always a reliable sign that one is dehydrated. The symptoms of dehydration vary from age to age.

Young Children

  • Sunken eyes
  • The child doesn’t wet diapers for more than two hours
  • A dry mouth, lips, and tongue
  • The child does not have tears when crying


  • Frequent fatigue
  • Regular occasions of dizziness
  • Confusion
  • Extreme thirst
  • The adult does not urinate as frequently as normal
  • Severely dry skin
  • Rapid breathing and heartbeat

When Should You See A Doctor?

While some dehydration cases may be mild some are severe and need immediate medical intervention. If you or your loved one has the following signs, see the doctor immediately.

  • Persisting diarrhoea that has been a nuisance for 24 hours or more.
  • Frequent loss of fluids from the body in form of sweat, vomit.
  • Has a show of bloody or very dark stool.
  • If there is minimal body activity than usual.

Risk Factors

No one is entirely safe from dehydration. However, there are specific groups of people that are at a higher risk of being dehydrated.

  • Young Children And Infants

Infants and young children are more susceptible to dehydration through vomiting and diarrhoea. They have a higher surface area to volume area ratio, which makes them lose more fluids than usual. Also, young children are not in a position to control themselves and know the right time to take water. In most cases, if not monitored, they will go for days without taking enough fluids which eventually leads them to dehydration.

  • The Elderly

As one ages, the body’s fluids reserve tends to get reduced hence the ability to conserve adequate water for the body becomes limited. Also, the sense of thirst becomes less sharp thus one may stay for long periods without having the urge to take water. These problems are tracked around by other chronic illnesses such as diabetes and intake of some drugs normally affecting the elderly. Another reason could be the mobility issue that limits the elderly from taking regular courses of fluids by themselves. All these reasons make the elderly more vulnerable to being dehydrated.

  • People Suffering From Chronic Diseases

Unknown or uncontrolled diabetes puts one at a risk of being dehydrated. Diseases that affect regular urination also puts one at a risk. Infections as small as flu or sore throats that would make you turn away from water intake may also cause dehydration. Any disease that limits water intake puts one at a risk of getting dehydrated.

People Who Workout And Exercise Outdoors

When you expose yourself to hot and humid temperatures, your risk of dehydration is likely to shoot up. If the lost water is not replaced immediately, you are likely to suffer from dehydration which should not be ignored.
