This study examines the impact of obesity on hospital use and healthcare costs across eight European countries, showing that obesity is associated with longer hospital stays and higher healthcare expenditure. It also highlights that even small reductions in obesity prevalence could lead to substantial savings for healthcare systems, underlining the importance of prevention strategies and the promotion of healthier lifestyles across Europe.
