Understanding Dehydration

Did you know that dehydration is the most common electrolyte imbalance in the world? It is also one of the most common medical conditions, affecting people of all ages.

In its simplest terms, dehydration occurs when the body loses more water than it takes in and becomes unable to perform its normal functions.

Causes of Dehydration

Sometimes dehydration is caused by reasons you might not even realize. If you’re busy, you might forget to hydrate. If you’re sick, you may not feel like eating or drinking, which can lead to dehydration. Even something as simple as not rehydrating during exercise can lead to dehydration.

Other dehydration causes are vomiting, diarrhea, extreme sweating, fever, excessive urination, and low blood pressure.

While dehydration may not always be severe, it can lead to serious health problems over time. So, if you notice any of the following signs and dehydration symptoms in a senior, it is vital to take them to a doctor for a check-up:

  • Dark Colored Urine
    • As the fluid in the body decreases, urine because less diluted, causing it to become darker.
  • Decreased Urination
    • As dehydration progresses, the kidneys lose water more rapidly, leading to decreased urination.
  • Difficulty Breathing
  • Dizziness
  • Dry Mouth
  • Fatigue
  • Feeling Faint or Lightheaded
  • Headache
  • Increased thirst
    • As dehydration worsens, the thirst receptor activates more intensely, leading to increased thirst and dehydration.
  • Nausea and Vomiting
  • Rapid Heart Rate
  • Sluggishness

Risk Factors

Dehydration is an often overlooked health risk yet a common problem in seniors that can lead to several health problems. But what are some of the risk factors that can lead to dehydration? Here are seven risk factors:

  • Age
    • The ability to conserve water decreases as we age and our sense of thirst becomes less acute. Our body’s fluid reserve also decreases as we age.
    • Though this article addresses dehydration in seniors, infants and children are also at greater risk for dehydration. They are the age group most likely to suffer from severe diarrhea and vomiting, leading to a loss of fluids. Plus, they aren’t able to verbalize that they are thirsty.
  • Chronic Illnesses
    • Diabetes
    • Kidney Disease
    • Medications
      • Especially medications that increase urination.
    • Sickness
      • When a person is sick, they often don’t feel like eating or drinking, which can lead to dehydration.
  • Exercise
    • Because a person sweats during exercise, they are losing fluids. If those fluids aren’t replaced with water, dehydration can occur.
    • Before exercising, drink some water. Continue to drink water or other liquids regularly during and after exercise to replace the lost fluids and avoid overheating.
  • Lack Of Water Intake
    • This is the most common risk factor for dehydration in seniors. If they aren’t drinking enough water, their blood pressure and blood sugar will drop, and they’ll become more susceptible to dehydration and other health problems.
  • Poor Oral Hygiene
    • Poor oral hygiene can lead to dehydration because it increases the risk of mouth infections and possibly cold sores, making drinking water difficult.
  • Poor Nutrition
    • A senior’s diet may not contain enough water-rich foods, thus leading to dehydration.
  • Working Outside
    • Dehydration and heat illness are more likely to occur with hot weather and when it’s hot and humid. Sweat can’t evaporate as quickly when the air is humid, resulting in a higher body temperature and the need for additional fluids.

Treating Dehydration

Dehydration, in most cases, is relatively easy to treat. The number one treatment is hydrating the body.

The fluids that have been lost must be replaced to treat dehydration. Drinking water or other beverages, such as juices or broths, is recommended for mild to moderate dehydration.

Vomiting or diarrhea may sometimes cause significant electrolyte and water loss. Drinking electrolyte drinks in these situations may be beneficial. Sports drinks and Pedialyte are examples of such beverages.

Hospitalization may be necessary for severe dehydration. Fluids and electrolytes will be given intravenously in this scenario.

Most important, especially in the elderly, is to call a health care professional if symptoms persist or worsen.
If you are experiencing a life-threatening emergency, call 911 or go to the nearest emergency department.
