It’s estimated that as many as 1 in 7 adults are suffering from constipation at any one time. And yet, talking about the problem is taboo.

Ruth Alexander is joined by two experts who want us to be more open about the condition. They say our reluctance to talk about constipation is having an impact on our well-being and creating a costly burden on health services.

Find out why a balanced and varied diet will help many people avoid the problem, but not all; and why prunes – a famous remedy – can actually make it worse.

Plus, a historian traces how we came to be so reticent about our toilet habits; and how constipation may have had a decisive role at numerous turning points in history.
