Obesity-related hospital admissions 'double in four years'
From the BBC
There were almost 617,000 appointments in 2016-17 where obesity was either a primary or secondary diagnosis - up from 292,000 in 2012-13.
Primary diagnoses involve weight-loss treatment, while secondary ones include hip problems and heart attacks.
Public Health England said it showed obesity was a "significant challenge".
Obesity is linked to a range of health problems, including heart disease, diabetes and cancer.
A secondary diagnosis of obesity means it would not be the reason for the admission but a factor that may contribute to the health issue and affect the type of care a patient receives.
Obesity was the main cause of 10,705 admissions - an 8% increase on the year before - and bariatric surgery appointments increased by 5% to 6,760 over the same period.
Those aged between 35 and 64 made up 69% of the admissions.
Women accounted for 66% of all obesity-related appointments and 77% of bariatric surgeries.
