Indigestion[sound recording].

Indigestion (heartburn / dyspepsia) is extremely common and often very distressing. Over a hundred million pounds a year are spent on over-the-counter indigestion remedies - are we spending our money wisely? When should one take indigestion more seriously and visit a doctor? We hear from a surgeon pioneering a new key-hole technique that could provide a life-long cure for acid reflux, for children as well as adults. We follow a woman as she undergoes an upper GI endoscopy.
