What is Constipation? 

 Constipation means it is hard to pass stool. People with constipation might: 

  •  Struggle to pass stool. 
  • Have small, hard, or dry stools. 
  • Feel bloated or uncomfortable in their belly. 
  • Feel like they still need to pass stool after they've gone. 

Why Do People Get Constipated? 

 Constipation can happen because of: 

  • Not drinking enough water. 
  • Not eating enough fibre (like fruits and veggies). 
  • Not moving or exercising much. 
  • Waiting too long to go to the bathroom. 
  • Health problems like Parkinson’s disease or after a stroke. 
  • Certain medicines or health supplements like iron or calcium supplements. 
  • Feeling really stressed.
