The final episode looks at the costly consequences of Britain’s increasingly obese teens. At Heartlands Hospital in Birmingham, younger and younger patients are being referred for help in tackling their weight and, increasingly, they are asking for a gastric band. While doctors and dieticians see the £6,000 operation as a last resort, some patients seek them as an “easy” solution to their weight problem. But the NHS weight management clinics can only help those who help themselves, and health professionals are hampered by young patients who don’t tell them the truth about what they are eating.
