Access to obesity treatment in the UK may be heading toward a two-tier system, raising concerns that some of the most vulnerable patients could be left without help.

From Science Daily

"Obesity is a complex, chronic disease that demands equitable access to treatment for all who need it -- not just those who can afford it. The current approach risks entrenching a two-tier system where wealth, rather than medical need, determines access to care. We urgently need a more inclusive, fair and scalable model that ensures effective treatments are accessible across all communities, especially those already facing systemic barriers to healthcare."
