More and more young people are being diagnosed with a condition once considered rare at their age
Researchers have warned about a striking increase in type 2 diabetes diagnoses among young adults across England, with women in their 20s experiencing some of the sharpest rises.
Scientists at Imperial College London spotted the trend in NHS records drawn from the English National Diabetes Audit, spanning 2011 to 2024.
The condition, which has historically been associated with middle and later life, appears to be gaining a significant foothold among a far younger demographic.
Although it remains more prevalent in older age groups, the shifting pattern is unmistakable, the scientists warned.
And it appears to be disproportionately affecting young people, who are receiving diagnoses that would have once been considered unusual for their age.
It was also noted that the trend has significantly accelerated in the years following the Covid pandemic, when obesity rates escalated dramatically.
The findings are consistent with separate NHS figures that show fresh obesity cases among adults aged 20 to 39 climbed sharply after 2019, despite rates in older cohorts actually falling.
Body mass index at the time of diabetes has also been increasing more rapidly in younger patients than older patients.
This is not a mere statistical curiosity, researchers warned; it carries heavy implications for the long-term health of an entire generation.
Scientists cautioned that early-onset cases tend to follow a more aggressive course, affording the disease more time to inflict damage on the blood vessels, nerves, eyes, kidneys and the heart.
Meanwhile, Diabetes UK has cautioned that being diagnosed at a younger age can elevate the chances of severe complications and reduce life expectancy.
NHS England estimates that there are approximately 12,000 individuals under the age of 30 living with the condition, with women making up a greater proportion of younger cases.
The figures highlight a pressing need for swifter intervention, given that the consequences of delayed treatment compound with every passing year.
What are the symptoms of diabetes?
Typically, symptoms of diabetes include persistent fatigue, frequent urination and constant thirst. But blurred vision, slow-healing wounds and recurrent infections may also emerge.
The difficulty is that oftentimes, the symptoms are subtle enough to be dismissed, particularly by younger patients who may not consider themselves at risk.
Clinicians are urged to maintain a low threshold for HbA1c testing in young adults, especially women with obesity, a history of gestational diabetes, or strong family links to the condition.
Fortunately, many people who receive a diagnosis while the condition is still in its infancy succeed at remission through weight reduction, dietary improvements and increased physical activity.
Newer pharmacological options such as GLP-1 medicines can also help.
Consultant practitioner Hussein Ahmad told GB News that patients often come in "saying they're tired, but it's not normal tiredness".
He continued: "It's the overwhelming fatigue that doesn't improve with rest. They blame work stress or getting older, when really their cells aren't getting the glucose they need for energy.
There's plenty of sugar in the bloodstream, but it's not being used properly.
He also said it's frequently recurrent infections that finally prompt someone to seek help, noting that women in particular may notice repeated thrush or urinary tract infections, along with small cuts that take far longer than usual to heal.
"These happen because high blood sugar creates an environment where bacteria and yeast thrive, plus it impairs immune function."
