Obesity and pain.

Recent reports suggest that almost half of the UK population is expected to be obese by 2030. A number of associations between obesity and chronic pain have been displayed in previous studies, and therefore it can be expected that the presentation of obese patients with chronic pain will rise in accordance with the prevalence of obesity. No single causative relationship between the two can be suggested, so the link between them is believed to be multifactorial. Despite this, little work has been done to draw together the many associations between obesity and pain. A better understanding of their connection, then, is required to appropriately manage this patient group that is increasing in numbers. This article aims to draw together existing evidence on the associations between obesity and pain to create a model of their multifactorial relationship. The article will systematically address each of the current theories in order to gradually build a diagrammatic representation of the relationship, which shall conclude the article.
