Hydration is important at every age, but for seniors, the aging process changes the composition of our bodies, and the amount of water in the body decreases. This means that dehydration can happen with less water loss, and impacts to your health can happen more rapidly and with less warning. Additionally, the sensation of thirst decreases as we age, so that even when the body does need more fluids, you may not experience any thirst to clue you in.
The primary cause of dehydration is of course not drinking enough fluids, but there are many other factors that can contribute as well. Illnesses causing diarrhea, vomiting or fever, increased sweating, and frequent urination can all deplete the body of its precious fluids.
Certain diseases or medications can also interfere with one’s ability to stay hydrated. Seniors with dementia or other memory issues may not remember to drink water throughout the day, or those suffering from diabetes or taking prescribed diuretics may urinate more frequently than normal.
One of the first signs of dehydration is the feeling of thirst, but for older adults they may not experience the sensations of thirst until dehydration is well under way. Feeling excessive thirst that is not easily quenched can be a sign of moderate to severe dehydration.
The simplest way to prevent dehydration is to drink more water. Setting a timer or using some other method to mark time to drink water on regular intervals can help keep you on track. Always make sure to have a glass or bottle of water on hand to serve as a visual reminder.
