In the UK, obesity costs the NHS more than smoking and alcohol related illnesses combined. As happy snappy said, they do get denied surgeries and similar treatment. It pisses me off because money is badly needed to go into mental health but the fat fucks take it all. As frustrating as this issue is though, I am so grateful for the NHS, I have had years of treatment and it has saved my life many times, knowing that an illness or injury won't bankrupt me is nice too.
