The word ‘constipation’ is generally used to describe bowel movements that are infrequent or difficult to pass. The stool is often dry, lumpy and hard, and problematic to expel. Other symptoms can include abdominal pain, bloating, and the feeling that one has not completely passed the bowel movement.

As many as 1 in 5 people say they have suffered from chronic (long-term) constipation at some point in their lives.
It results in more than 2.5 million hospital and physicians visits per year in the USA.
And Americans spend more than $700 million on treatments for it annually (Source).
