Recent changes in the patterns of chronic digestive disease in the United Kingdom.

Chronic alimentary complaints, though persistent in individuals, impose a varying degree of burden upon society in general. The reasons for these fluctuations remain largely unknown, but the speed with which changes occur suggests that the impact of environmental factors can become apparent after relatively short intervals have passed in which those influences have been at work. These concepts can be illustrated by considering peptic ulcer, coeliac disease and chronic inflammatory bowel disease.
