To ask His Majesty's Government what is the total cost of treating patients who are obese and overweight; and what are the associated costs of treating (1) type 2 diabetes, (2) cardiovascular disease, (3) cerebrovascular disease, (4) musculoskeletal diseases including joint replacers, (5) cancer, and (6) dementia.

The department has reviewed and uses cost estimates published by Frontier Economics in 2022.

A study by Frontier Economics estimated that in 2021 obesity related ill-health cost the National Health Service £6.5 billion annually. This estimate includes costs associated with the following obesity related diseases: colorectal cancer; oesophageal cancer; kidney cancer; ovarian cancer; pancreatic cancer; coronary heart disease; stroke; type 2 diabetes; hypertension; knee osteoarthritis; endometrial cancer, and breast cancer.

The disease costs associated with obesity are calculated from the total annual costs per case, as shown in the following table:

The annual costs per case includes direct health-care costs including hospital care (both inpatient and outpatient), primary care, and medication, and they are not exclusively related to obesity associated cases. Indirect and social care costs are not included, which means the exclusion of these costs will probably underestimate total costs of disease events overall.
