The Obesity Admissions Crisis: Which NHS Trusts Are Carrying the Greatest Burden?
Freedom of Information (FOI) data revealing obesity-related admissions across 163 NHS trusts exposes a stark regional divide and a healthcare system under compounding strain.
Key Insight 1
Six of the UK's ten most burdened NHS trusts are in the North of England.
Key Insight 2
Manchester trusts recorded over 160,000 admissions for obesity, Type 2 diabetes and coronary heart disease (CHD).
Key Insight 3
The gap between the trusts with the most and least admissions is vast; Manchester scores 94.5 on the burden index, while the lowest-ranked areas score just 1.3.
The Ongoing Obesity Crisis
Obesity doesn't just affect individuals; it takes a toll on healthcare systems. Left unaddressed, it compounds and drives up rates of Type 2 diabetes, coronary heart disease and stroke, conditions that are chronic, costly and, in many cases, preventable. The longer they go unmanaged, the greater the pressure they place on the services responsible for treating them.
To understand where that pressure is greatest, we at The Independent Pharmacy submitted Freedom of Information requests to 163 NHS trusts across the UK, requesting admissions data for four obesity-related conditions: recorded obesity diagnoses, Type 2 diabetes, coronary heart disease and stroke.
The result is a trust-by-trust picture of where obesity's clinical consequences have accumulated most heavily and which communities are bearing the burden.
What emerges isn't a story about individual choices. It's a story about geography. Where you live shapes the environment around you, the food available, the services accessible, and the support on offer. For millions of people across the UK, those environments have been quietly stacking the odds against them for years. This data shows where that imbalance has become a crisis.
Obesity admissions: the areas hit the hardest
This dataset ranks NHS trust areas across the UK based on recorded admissions for obesity and its most closely linked conditions: Type 2 diabetes, coronary heart disease and stroke. Each area received an index score reflecting the combined volume of these admissions, giving a measure of the overall obesity-related disease burden carried by each trust.
Manchester sits at the top by a considerable margin, with an index score of 94.5, nearly 16 points ahead of second-placed Stoke-on-Trent (78.9). It reveals how Manchester's trust is handling a substantially greater volume of obesity-related conditions than anywhere else in the UK.
The North of England dominates the top ten. Manchester, Stoke-on-Trent, Leeds, Northumberland, Lancaster and Middlesbrough all feature, with Coventry and Worcester the only Midlands entries to break through. This regional concentration reflects wider patterns of obesity prevalence and deprivation across the North, where unhealthy environments and limited access to preventative care have allowed these conditions to accumulate over time.
Type 2 diabetes is the single biggest driver across the top-ranked areas. In Manchester, Leeds, Worcester and Stoke, diabetes admissions alone run into six figures, a volume that places sustained, chronic pressure on services well beyond a single department or speciality. These aren't acute spikes in demand; they represent a persistent, compounding load that trusts are managing year after year.
What the index also reveals is how differently obesity manifests across areas. Some trusts, like Gateshead and Great Yarmouth, rank relatively highly despite lower recorded obesity diagnoses, driven instead by elevated rates of coronary heart disease and Type 2 diabetes, conditions that often trail obesity by years. The disease burden, in other words, isn't always visible in obesity figures alone. By the time it shows up in CHD and stroke admissions, the damage is already done.
Beyond the top ten, the data reveals a steep drop-off. Areas ranked 25th and above on the table have index scores under 13, while the bottom entries, including parts of Wales, Scotland and Northern Ireland, score below 2. The burden isn't evenly spread. It is heavily concentrated in a handful of urban and post-industrial areas that have faced decades of structural disadvantage.
Speaking on the study, Dr Donald Grant, GP and Senior Clinical Advisor here at The Independent Pharmacy, said:
"What this data makes clear is that obesity is not a condition that arrives and resolves; it accumulates. Every year that it goes unaddressed at a population level, the downstream consequences grow: more diabetes diagnoses, more cardiac events, more strokes. The trusts at the top of this index aren't dealing with a short-term spike in demand. They are managing the compounded result of years of inadequate prevention, limited access to support and environments that have made unhealthy choices for the path of least resistance. Until we treat obesity as the systemic issue it is, the admissions burden on trusts like those in Manchester, Stoke and Leeds will only continue to rise.”

Methodology
We submitted Freedom of Information requests to 163 NHS trusts across the UK. Trust-level admissions data were collected for four obesity-linked conditions: recorded obesity diagnoses (ICD-10 code E66), Type 2 diabetes (E11), coronary heart disease and stroke. Each trust was scored and ranked based on the combined volume of admissions across all four conditions, resulting in a composite index reflecting the overall obesity-related disease burden for each trust. This dataset covers NHS trusts across England, Scotland, Wales and Northern Ireland.
