The Importance of Fluids in Dementia Care

July 10, 2024 Reading time: 6 minutes

In dementia care, ensuring proper hydration is a crucial component often overlooked. Yet, the importance of fluids for dementia patients cannot be understated. This blog post will delve into the reasons why fluids are crucial for people with dementia and how proper hydration can significantly enhance their overall health.

Understanding the Impact of Dementia on Hydration

Dementia is a progressive condition that impairs cognitive function and memory, making it challenging for individuals to perform everyday tasks, including maintaining proper hydration. As dementia advances, patients may experience difficulties in recognizing thirst cues, remembering to drink water, or communicating their needs effectively. This can lead to dehydration, which can exacerbate symptoms of dementia and negatively impact their quality of life. 

Why dehydration is a Risk for Dementia Patients?

Dehydration happens when the body expels more fluids than it absorbs, resulting in an imbalance of vital electrolytes. This condition can be particularly severe for individuals with dementia. It may exacerbate cognitive symptoms, leading to heightened confusion, delirium, and changes in behaviour. Additionally, it can cause physical issues such as urinary tract infections, constipation, kidney stones, and potentially life-threatening situations like kidney failure. Since dementia patients may already have compromised immune systems, dehydration can significantly increase their vulnerability to infections.

The Importance of Fluids for Dementia Patients

Brain Function: Adequate hydration is vital for optimal brain function. Dehydration can lead to cognitive impairment, confusion, and disorientation, all of which can worsen symptoms of dementia. By staying hydrated, dementia patients can maintain better cognitive function and clarity of thought.

Physical Health: Proper hydration is essential for overall physical health. Dehydration can cause a range of health issues such as urinary tract infections, constipation, and increased risk of falls. By ensuring that dementia patients are well-hydrated, caregivers can help prevent these complications and promote better overall health.

Emotional Well-being: Dehydration can also affect mood and behaviour in individuals with dementia. It can lead to increased agitation, restlessness, and irritability. By keeping dementia patients hydrated, caregivers can help improve their emotional well-being and reduce challenging behaviours.

As we explore the difficulties of caring for people with dementia, it is important to acknowledge the critical role that hydration fluids play in sustaining their health and well-being. Hydration is more than just drinking a glass of water; it is a key factor contributing to cognitive function, overall physical health, and emotional well-being. In this post, we will examine why fluids are so important for people with dementia and why staying hydrated is so important for their quality of life. 

What are the Reasons Dementia Patients Not Drinking Enough Fluids?

Patients with dementia often face difficulties in maintaining hydration due to several factors associated with their condition. Cognitive impairments may lead them to forget to drink or not recognise thirst. Many also suffer from dysphagia, a difficulty in swallowing, which can render the act of drinking uncomfortable or painful, causing them to avoid it. Additionally, the fear of incontinence may lead some to deliberately reduce their fluid intake to avoid accidents. Certain medications for dementia, like diuretics, exacerbate fluid loss, increasing the risk of dehydration. This can intensify their symptoms and lead to severe health issues. Caregivers need to understand and proactively address these challenges to ensure patients with dementia stay properly hydrated and maintain their overall health.

Did you know that every organ in our body needs fluids to function effectively?

The brain is highly reliant on fluids. All organs in our body need fluids to function optimally, and the brain requires proper hydration to operate effectively. Insufficient water intake can lead to problems such as short-term memory loss, confusion, agitation, and concentration difficulties, which are particularly pronounced in individuals with dementia. These issues can greatly affect their quality of life and ability to perform daily tasks. People with dementia need to maintain adequate hydration throughout the day to support cognitive functions, mood stability, and general alertness. Making sure they consume sufficient fluids can significantly improve the management of dementia symptoms and their overall well-being.

So, how can we make sure our loved ones living with dementia can stay hydrated?

Maintaining hydration in dementia patients is crucial, and while water is the optimal choice, other liquids can be helpful too. Alternatives such as fruit juices, milk, and herbal teas offer additional nutrients. Flavoured water or diluted fruit juices might appeal to those who prefer something sweet. Soups, broths, and fruits with high water content like watermelon, oranges, and grapes also aid in meeting their hydration needs. For those who have difficulty swallowing, thickened drinks or smoothies may be more manageable and still ensure adequate hydration.

Strategies for Promoting Hydration in Dementia Care

  • Make sure they have a glass of water handy at all time
  • Offer them fluids regularly, especially when they seem thirsty 
  • Flavoured water or soups to make drinks appealing 
  • Keep a close eye on their fluid intake and make sure they are not dehydrated
  • Encourage them to drink a full glass of water as soon as they wake up. This is a good kickstart to the brain and the body. 
  • Get help from a Smart speaker system or an alarm system to remind them to drink fluids.  
  • Change the regular glass to a colourful one and use a coloured straw if required. 
  • Please stop using the side table, make sure the table is at the front where they mainly sit.  
  • If possible, label the bottle or glass saying “Drinking Water”.
  • Use a glass or plastic tumbler with a reusable silicon straw, make sure your loved one can lift it when full of fluids. 450ml – 600ml is highly recommended and available in supermarkets or online. 

In some cases, a person with dementia refuses to drink, especially water! Making their fluid intake up with food, such as Soup, watermelon, pineapple, pears, yoghurts and custard will help to be hydrated. 

In conclusion, ensuring adequate hydration is crucial for the overall health and well-being of individuals with dementia. Recognizing the dangers of dehydration, being aware of its symptoms, and adopting methods to promote adequate fluid consumption can greatly enhance the life quality of dementia patients.
