The definition of dehydration is that you lose more fluid than you take in. Many of us believe dehydration is prevented by our body’s natural sense of thirst to remind us to pour ourselves a glass of water. But, the fact is, as we get older, our sense of thirst will diminish significantly. Hydration is vital because it keeps electrolytes balanced, blood volume normal, aids digestion, transportation of nutrients, and kidney functioning.
Signs of dehydration in older adults:
- Dry skin and mouth or cracked lips
- Confusion
- Fatigue
- Mobility difficulty
- Dizziness
- Sunken eyes
- Inability to sweat or produce tears
- Rapid heart rate
- Low blood pressure
Five Reasons Seniors Need to Stay Hydrated
As we age, several physiological changes can put seniors at a higher risk of dehydration, such as increased fluid loss, reduced body water content, and decreased fluid consumption.
Decreased Thirst: It’s a fact that we lose our sense of thirst with age, and older adults may overlook their need for hydration. Keeping up with your daily water or fluid intake will help prevent a medical emergency.
Kidney Function: Our kidneys are responsible for filtering out blood by removing waste, controlling the body’s fluid balance, and keeping electrolytes at the correct levels. Unfortunately, kidney function can diminish as we age, decreasing the body’s ability to create urine or remove waste. Staying fully hydrated helps to keep kidneys functioning to the best of their ability.
Brain Power: Dehydration symptoms in seniors can mimic signs of dementia. Why is that? Because dehydration is just as critical for brain function as it is for body function. Cognitive function is enhanced when brain cells get the proper amount of hydration.
Urinary Incontinence: It is uncomfortable and frustrating. Some seniors avoid drinking to avoid the experience, which can lead to other health risks. Reduction in fluids can cause urinary tract infections, which can cause pain and sometimes dementia-like confusion.
Digestion: Dehydration can cause constipation. Staying hydrated and consuming the proper amount of fibre helps seniors remain regular. Lack of water can lead to gastritis, acid reflux, and in some cases, ulcers, as the stomach does not have enough water to produce digestive acid. Research has shown that drinking water can help limit acid reflux symptoms by temporarily raising the stomach’s PH.
