Elderly Care in Arlington VA: Dehydration is quite common in seniors and it can lead to several health issues and further complicate existing problems. Because the total body water decreases as people age, seniors can get dehydrated more quickly than younger adults do. Dehydration can cause a lot of problems with seniors, from constipation and urinary tract infections to kidney stones, respiratory conditions, slower wound healing and dizziness which lead to falls. Family caregivers need to take steps to ensure that their senior loved one is properly hydrated, especially in warm summer weather.
