Dehydration in Seniors
Seniors may be at a higher risk of dehydration due to a decreased sense of thirst, which is a common early warning sign of mild dehydration. Seniors should also be aware that fear of being incontinent, swallowing difficulties, and gastrointestinal disorders contribute to their risk of becoming dehydrated. A lack of proper hydration may cause seniors to experience an increased risk of infections, pressure sores, falls, and broken bones.
Total body water decreases with age. Adults over 60 have less water to lose, which creates the risk of dehydrating more quickly than when they were younger. Living a healthy lifestyle and providing your body with adequate water each day can slow down premature aging and prevent many seniors from visiting the hospital due to dehydration.
There are also certain risk factors you should watch for to detect early dehydration:
- Swallowing disorders are caused by stroke, as well as Parkinson’s disease or dementia.
- Obesity
- Seniors over the age of 85.
- Being sedentary for long periods, such as being bedridden.
- Diarrhea, vomiting, or excessive sweating.
- Chronic diseases can contribute to dehydration, especially when having more than five chronic diseases.
- Medications for other ailments, especially when taking more than five prescription medications at a time.
Knowing risk factors and being aware of the signs of dehydration can help you spot them and rehydrate before it is too late.
Signs of dehydration include:
- Loss of skin elasticity
- Concentrated urine
- Dizziness
- Increased heart rate
- Dryness in the nose and mouth
- Constipation or decreased bowel movements
- Bowel discomfort
- Acute confusion
Water hydrates every cell and every organ in the body, including the brain. More than 2/3 of the brain is made up of water. Age can affect the body’s physical and cognitive functions. Water won’t solve this problem, but it is necessary for seniors in their daily lives. Five 8-ounce glasses of water a day is a good benchmark for elderly patients. Everyone’s needs vary, but studies have shown that seniors who drink five glasses of water a day experience lower rates of fatal coronary heart disease. In addition to water, milk, juices, and foods high in water can hydrate the body.
It is vital to ensure you and your loved one are drinking enough water and get the exercise and activity needed for health and overall well-being. Remember to make water consumption an important part of your daily routine.
Healthy Routines
Maintaining hydration is not just about drinking enough water—it also involves creating healthy routines that make fluid intake easier for seniors. For example, keeping a filled water bottle nearby throughout the day or setting reminders can encourage consistent sipping rather than waiting for thirst to strike. Caregivers can also offer fluids at regular intervals, especially to seniors who may forget or are reluctant to drink on their own.
Another helpful strategy is to make hydration more enjoyable. Infusing water with slices of lemon, cucumber, or berries can add flavor without added sugar. Warm, low-sodium broths or herbal teas can be comforting alternatives during cooler months. Many fruits and vegetables—such as watermelon, oranges, cucumbers, and lettuce—are also rich in water and can supplement fluid intake while providing important nutrients.
It is equally important to understand that dehydration can often be mistaken for other health problems. For instance, fatigue, confusion, or irritability may be misattributed to aging or illness when they could actually be warning signs of insufficient hydration. Recognizing these subtle signals early allows for quick intervention before dehydration becomes severe.
Preventing dehydration requires a proactive approach. Family members, caregivers, and healthcare providers should all play a role in monitoring fluid intake, especially during hot weather, illness, or periods of medication changes. Seniors who make hydration a daily priority often experience improved energy, better digestion, and enhanced mental clarity.
By staying mindful of fluid needs and making small adjustments to daily habits, seniors can protect their health, reduce hospital visits, and enjoy a greater quality of life well into their later years.
