Adult obesity 1: tackling the causes of the obesity epidemic and assessing patients.

This first in a two part unit on adult obesity examines the prevalence, causes, consequences and assessment of this condition. It explores the rising prevalence rates, offers an explanation for the increasing predisposition to obesity and identifies its effects on the body. Metabolic syndrome is shown to be pro-atherogenic and a precursor to cardiovascular disease and diabetes. This part also outlines how to assess patients, and discusses the best way to broach the awkward subject of weight with those not even aware they are at risk.
