Hundreds of thousands of people with diabetes face the possibility of severe complications that the NHS need to prepare for, according to a global diabetes audit.
The audit stated that the NHS should prepare for the likelihood that these patients may need substantial hospital care in the future.
It identified a so-called postcode lottery in the types of treatments offered by different hospitals and warned that diabetics under 54 are more likely to be overlooked for essential checks including blood pressure, blood sugar, weight and foot care.
Some 42% of patients aged 25 to 54 get the nine basic health checks, compared with 54% of those aged 55 and over.
Both forms of diabetes are on the rise; currently 300,000 people in the UK have Type 1 diabetes which usually develops in childhood. Type 2 diabetes, linked to obesity and unhealthy lifestyles, has been diagnosed for 2.5 million people, while up to a million more are believed to have the condition without knowing it.
