This book provides up to date information about IBS and its developments in the last decade and provides ways of controlling IBS based on the authors' long experience in treating IBS patients. Although IBS is a tortuous disorder and interferes with the patients’ daily activities, it does not develop into a serious disease or kill its sufferer.
