A quarter of COVID-19 patients who have died in hospitals in England had diabetes, according to official figures.
For the first time, NHS England has published a breakdown of deaths by pre-existing conditions, showing only five per cent of victims didn’t have one.
Of the 22,332 patients who died since March 31, when pre-existing conditions began to be reported, some 5,873 (26 per cent) of patients had diabetes.
The chronic condition – affecting an estimated four million Britons – makes people more susceptible to developing infections.
High blood sugar levels can weaken the patient’s immune system defense, making it slower to respond to viruses such as SARS-CoV-2.
It’s also closely connected with obesity and ethnicity, which have independently been recognised as potential risk factors for COVID-19 mortality.
Doctors today said diabetics would have better COVID-19 outcomes if they managed their condition properly.
Figures also show that almost one fifth of COVID-19 victims in hospitals had dementia and 15 per cent had COPD.

The Government’s official death tally shows that 33,614 people have died of COVID-19 in the UK.
More than to 24,100 people have died from the virus in hospitals in England.
From today, the NHS has started to publish rolling information on the health conditions of COVID-19 patients.
Of those that have occurred since March 31 (22,332), 5,873 patients who died were suffering from diabetes.
Diabetes is a common condition affecting an estimated one in 16 people in the UK. That includes both diagnosed and undiagnosed people.
Dr Hajira Dambha-Miller, a GP and specialist in diabetes, said she was not surprised by the data.
She told MailOnline: ‘People with diabetes are more susceptible to infections, even if we are not in the middle of a pandemic.
‘Diabetes leads to greater susceptibility to infection because there is more sugar for bugs to grow on and chronic inflammation means the immune system is slower to clear it.’
Dr Dambha-Miller said when someone has diabetes, their blood becomes ‘like treacle’ as a result of high sugar levels.
‘Physically, it’s harder for the immune system to get to the virus,’ she said. ‘The virus bugs do a lot of damage before the immune system even realises it’s there.
‘When the body does kick in, it won’t work as it should do. The immune cells are damaged because they’ve been saturated in sugar for years and don’t work the way they should.’
Management of diabetes is notoriously difficult. It involves dealing with short term events, such as high and low blood sugar, as well as understanding how to cope with the condition in the long term.
Dr Damnha-Miller said: ‘The better the sugar control, the better the outcomes for people with diabetes. If people are really careful about sugar control, over the long term, this will be helpful in improving outcomes. There is tonnes of evidence on this from everyday infections like flu or colds.’
Diabetes is linked to obesity and ethnicity – both of which have independently been identified as risk factors for COVID-19 disease severity.
Nine in ten of diabetics are type 2, which is offset by an unhealthy lifestyle. Rising diagnoses of type 2 diabetes parallels soaring obesity levels.
Ethnicity plays a big role in the prevalence of diabetes – it is four times more prevalent in Bangladeshi and Indian people.
Pakistani women are five times more likely to develop diabetes, and Indian have an increased risk of 2.5-fold, according to the charity Diabetes.co.uk.
Generally speaking diabetes prevalence is often six times higher for people of South Asian origin and three times higher for those of African origin.
Emerging evidence linking obesity and ethnicity with COVID-19 has prompted an investigation by Public Health England.
A major study in Glasgow last week found that obesity may double the risk of needing hospitalisation for COVID-19.

And Government data shows the risk of dying from the coronavirus is ‘significantly’ higher among some ethnic groups compared to white people, when age was taken into account.
For example Black people are four times more likely to die from the virus, which only reduced by half when taking health conditions and other factors into account.
Commenting on the NHS figures, Bridget Turner, director of policy at Diabetes UK, said: ‘The fact that more than a quarter of people who have died with COVID19 have diabetes underlines the urgent need to ensure better protection and extra support is available to those in the clinically vulnerable groups.
‘We still urgently need to understand through research why people with diabetes are affected in such numbers. But until we know more, people living with diabetes should be supported to manage their condition.’
Diabetics are among the most vulnerable to severe COVID-19, but are not considered ‘extremely high risk’ by the Government.
They are able to leave their homes for exercise and to get medication, unlike those with rare cancers or organ recipients who should not leave their home under any condition.
Ms Turner urged the Government to make sure those with diabetes are protected if they are expected to return to work in the feasible future.
‘Government must ensure urgently that employers take all the necessary measures to keep employees with diabetes safe, if they are expected to attend work outside the home as restrictions are eased,’ she said.
‘This includes ensuring the guidance for employers is clear, consistent, and focused on the safety of employees above all else.’
Dementia was the second most common condition linked with COVID-19 deaths – 18 per cent of victims had the memory disease.
Following that was COPD, (chronic obstructive pulmonary disease), which covers a number of lung conditions. Nearly one in seven of COVID-19 victims had COPD.
Some 14 per cent of victims had kidney disease, 10 per cent had ischaemic heart disease and seven per cent had asthma.
NHS England said the accuracy of the data is reliant on the availability and transfer of information by healthcare providers, and patients may have had more than one pre-existing condition.
It comes after a study warned more than 8million people in Britain are at a higher risk of dying if they catch COVID-19 because of their age or poor health.
But most of this group are not deemed ‘extremely clinically vulnerable’ people, who were asked to ‘shield’ for 12 weeks by the Department of Health.
