UK obesity institute targets future NHS treatment

England recorded 8,716 hospital admissions directly attributable to obesity in 2022 to 2023, up 13% from the previous year. During the same period, obesity was a factor in more than 1.2 million hospital admissions, an 8% rise on 2021 to 2022.

Against that backdrop, the Medical Research Council (MRC) and the British Heart Foundation (BHF) are investing £72 million in the new UK Obesity Research Institute (UK-ORI). The institute will investigate why obesity affects some people differently, how it contributes to long-term illness and which treatments can improve outcomes.

The figures describe hospital activity, not the number of people with obesity, and the source does not attribute the increases to one specific cause. They do, however, show the scale of the health-system burden that the new research programme is intended to address.

Research will examine the biological causes of obesity

UK-ORI will bring together biomedical science, medicine and technology to study the origins, prevention, treatment and health consequences of obesity. Researchers will examine the roles of genetics, hormones, the brain, metabolism, behaviour and the environment.

That approach reflects the institute’s stated view that obesity is a complex biological condition rather than simply a matter of excess body fat or eating too much. The aim is to understand why the condition develops differently between individuals and to support more targeted treatment.

The institute will also investigate how obesity is connected to chronic diseases, including cardiovascular disease and cancer. BHF funding will focus specifically on the impact of obesity on cardiovascular health.

Why cardiovascular disease is a central focus

Obesity is linked to changes in metabolism, chronic inflammation and mechanical strain on the body. It can contribute to high blood pressure and unhealthy cholesterol levels, increasing the risk of heart attacks, heart failure, atrial fibrillation and stroke.

The source also identifies links with type 2 diabetes, steatotic liver disease, gallbladder disease, several cancers, obstructive sleep apnoea, osteoarthritis and chronic kidney disease. These are described as health consequences associated with obesity, but the announcement does not claim that every person with obesity will develop any particular condition.

Professor Bryan Williams, chief scientific and medical officer at the British Heart Foundation, said obesity is linked to tens of thousands of heart attacks and strokes in the UK every year. He said the institute would help researchers develop new ways to prevent and treat the condition.

How discoveries could reach patients

A key part of UK-ORI’s work will be experimental medicine: testing biological mechanisms in humans so that promising therapies can be assessed safely and effectively. The institute will span discovery science, clinical research and translation into healthcare.

It will also strengthen links between universities, industry and healthcare providers. The intended result is a faster route from a research finding to a treatment or other intervention that can benefit patients.

Professor Patrick Chinnery, MRC executive chair, said obesity-related illness costs the NHS £6 billion annually and is a leading cause of preventable premature death. He said the institute’s combined expertise could help produce evidence and innovations to improve health outcomes for millions of people.

The £72 million investment establishes the research capacity; the announcement does not provide a timetable for specific treatments, clinical recommendations or reductions in hospital admissions. Those outcomes will depend on the findings generated by the institute and how safely they can be translated into practice.
