Preventing Dehydration

It’s been slow coming but summer has finally arrived. It won’t be long before we start hearing TV and radio announcements about municipal “cooling centers” being opened. These announcements point to the importance of staying hydrated, particularly in the summer. This is especially critical for the elderly and the frail. Dehydration can quickly lead to heat exhaustion or heat stroke for this group. Older people are at a greater risk of dehydration for several reasons. While a younger person’s body naturally cools itself through the production of perspiration, this mechanism may not work as well in a senior due to natural aging changes and the assortment of medications they may be taking for a variety of chronic conditions. These medications include antihistamines, antidepressants, motion sickness medication, anti asthma drugs, diuretics which are often prescribed for hypertension, and some heart medications. In addition, as we get older our kidneys are less efficient at conserving water and unlike camels, we can’t store it. By the time your aging loved one’s body sends them the “I’m thirsty” signal, they may be well on the way to being dehydrated. Seniors who have dementia may simply forget to drink and those who suffer from neurological disorders may have difficulty swallowing. Those who are frail need assistance to drink. Any combination of these factors can lead to dehydration.

According to the CDC (Center for Disease Control), there are signs of dehydration to look for: dizziness, confusion, constipation, increased fatigue, increased body temperature, dry mouth, reduced sweating, sunken eyes, and low blood pressure. As a caregiver, taking extra measures to keep your loved one hydrated requires vigilance but in this case, an ounce of prevention is definitely worth a pound of cure. Be sure to offer fluids on a regular basis, at least every couple of hours. Although plain, clear water is the best choice, any liquid is better than none so offer your loved one their preferred beverage frequently. Be sure to serve beverages with meals and encourage more than a sip of water to wash down medications. Try serving foods that are naturally “wet” such as soups, yogurt, ice cream, and smoothies. Encourage your loved one to drink small quantities frequently rather than a lot at one time. A frail senior needs at least 6 cups of fluids per day but consult their doctor if they take diuretics, have kidney disease, or have congestive heart failure.
