What Older Adults Need to Know About Hydration
Your risk of dehydration – and your chances of experiencing serious side effects – increases with age.
Key Takeaways
- Dehydration poses health risks to people of all ages but it’s especially dangerous for vulnerable older adults.
- Older adults may be less likely to notice signs of dehydration due to age-related changes in senses, such as a diminished ability to register thirst, making older adults less likely to realize when they need to drink. Muscle tissue holds a significant amount of water, so a decline in muscle mass (sarcopenia) can reduce the body’s overall water storage capacity.
- As kidneys age, their ability to filter and conserve water may decline, leading to increased fluid loss through urination.
- Symptoms of dehydration can be mild, such as fatigue and dry mouth, and progress to more serious, including dizziness, weakness, confusion, muscle cramps, rapid heart rate and kidney damage.
- Adopting good hydration habits, like carrying a water bottle throughout the day and setting reminders to drink fluids, can help older adults prevent dehydration.
Dehydration can cause a range of symptoms from brain fog to kidney stones. It can affect people at any age but can be particularly burdensome to vulnerable older adults.
Studies show a high prevalence of chronic dehydration among older adults, which suggests that age elevates dehydration risks. Different definitions of hydration have yielded different statistics on the prevalence of dehydration in older adults, but the numbers range from around 40% to up to 66%.
These stats highlight the importance of staying hydrated for seniors.
