Tackling Dehydration In The Elderly

Weekend call banner

What is dehydration?

Dehydration affects all ages, in particular babies, children and the elderly. According to the NHS dehydration is when ‘your body loses more fluids than you take in. If it’s not treated, it can get worse and become a serious problem.’

Our bodies are made up of around 60% of water and drinking the right amount of water helps our organs function, provides us with some of the essential nutrients and helps the heart to pump blood to the muscles. So, whether you enjoy a glass of fruit juice or a hot cup of decaf tea, it’s important to monitor your fluid intake and know how to avoid getting dehydrated.

Risks Of Dehydration In The Elderly

Older people are generally at a higher risk of dehydration as they have a lower percentage of water in their bodies. According to Hydration for Health, between the age of 20 and 80, “the amount of body water decreases by 15%,” which is about six litres of fluid – making the elderly more susceptible to dehydration.

As we age, you may find your sense of thirst naturally weakens and therefore, your fluid intake decreases. Thirst is a sensation that can provoke dehydration and not realising when you need water is a high-risk factor.

Furthermore, with aging our kidneys lose the ability to retain water, putting the elderly at a higher risk than younger adults. We rely on our kidneys to retain water when our bodies need it most, but when they are unable to function properly, water intake will need to increase to replenish the fluids.

Other risk factors include medication, forgetfulness, needing assistance with eating and drinking, and the condition you are living with. For example, if you are living with dementia water loss can be worse, as according to, individuals may simply forget to drink or find it difficult to communicate that they are thirsty.

Effects Of Dehydration

With age, our bodies naturally change and the function of our organs begins to decline, which is why dehydration is a bigger risk for the elderly.

As we age, our joints start to get stiff, but a few glasses of water or fruit juices can help lubricate your joints, protect sensitive tissues and the spine. Dehydration is said to cause the spinal discs to lose water, resulting in back pain. The inner and outer rings of the discs are filled with water, which helps support the spine. They lose water every day, so it is important to keep drinking to keep backaches at bay.

Dehydration can also lead to seniors feeling confused, which is especially difficult for those living with dementia, as the symptoms of dementia can get worse.

Plus, the elderly are more prone to be hospitalised and if dehydration isn’t treated the right way, it can be life-threatening.

Prevention is the best way to tackle dehydration. Keeping up with fluids and snacking throughout the day will help you stay hydrated, maintain your body temperature, aid digestion, and provide your body with the essential nutrients to function.

How To Identify The Warning Signs Of Dehydration

It is important to know what to look for when you are feeling dehydrated, so you can treat it before it becomes worse. Common signs include dry mouth, tongue and lips, confusion, dizziness, and nausea. You may notice that your urine is more concentrated and has a strong odour, which is an indicator of dehydration.

In severe cases, low blood pressure, muscle cramping, and a rapid heartbeat are all warning signs of dehydration – so you must be aware of these symptoms and drink plenty to prevent it.
