Cases of the inflammatory bowel condition known as diverticulitis peak in summer and autumn and drop off in winter, showing consistent seasonal variation, according to Australian research which suggests that environmental or behavioural factors such as Vitamin D exposure, dehydration or changes in diet, may be involved.
