Spotting the signs of dehydration and simple first steps …

What is dehydration?

Dehydration is when we don’t drink enough fluids to maintain a healthy balance in our body. Water makes up two thirds of our body. A healthy fluid balance is needed to help digestion, flush out waste and toxins and to keep the skin healthy. Most people get dehydrated by not drinking enough fluids or by losing fluids and not replacing them.

Who is at high risk?

You, or someone you care for, may be at risk of dehydration if you:

  • Are dependent on others for the provision of, or access to fluids
  • Have swallowing problems
    Have a raised temperature
  • Have diarrhoea and/or vomiting
  • Have taken part in physical activities
  • Are in a very warm room or the weather is hot
  • Are limiting your drinks because you have difficulty getting to the toilet on time
  • Are limiting your drinks because you don’t want to get up through the night to go to the toilet.

What to do if you are concerned about someone else?

You can help prevent dehydration by:

  • Being aware of the early warning signs
  • Sitting down and having a drink or cup of tea together
  • Planning visits around mealtimes to understand if there are any difficulties with drinking
  • Having a look in the fridge or cupboards to check there are enough things to drink
  • Encouraging attendance at local cafes/ local lunches / visiting voluntary, community or faith organisations with luncheon clubs
  • Ensuring both hot and cold drinks are safely and freely accessible
  • Encouraging around 6-8 drinks per day
  • Be aware that other food such as jelly, soup, yoghurt, milk puddings, ice-lollies, and some fruits also contain fluid
  • Supporting access to both social and health services.
