Virtually everyone has had indigestion at some time & for most people it's simply a minor nuisance. More often than not it happens when you've overindulged or eaten something that doesn't agree with you & it only lasts for a short time. For some people the symptoms can be persistent & so severe that they interfere with everyday life. The symptoms may be caused by some undiagnosed problem within the digestive system which needs to be properly identified & treated by a doctor. This book will help you distinguish between minor symptoms which you can safely treat yourself & those that need further investigation.
