Our bodies are made up of about two-thirds water. We only need the total water level to drop by as little as a few percent for us to become dehydrated – that is, lacking in water. Lack of water can eventually lead to problems within the body, such as kidney stones, and liver, muscle and joint damage. 

Having Crohn’s Disease or Ulcerative Colitis can sometimes increase the risk of becoming dehydrated. This information sheet looks at why this may happen and some ways to prevent and treat it.
