Something is quietly shifting in GP surgeries across England, and it’s not a story that’s getting nearly enough attention. Type 2 diabetes, long thought of as a condition that crept up on people in middle age, is now being diagnosed in women in their twenties at a rate that’s genuinely alarming doctors.
Diabetes UK flagged the trend earlier this year, pointing to a “worrying increase” in younger women developing the condition. It’s not a blip. It’s a pattern, and it’s been building for a while.
So what’s driving it? A combination of factors, really. Ultra-processed food has become the dietary backbone of a generation that’s short on time and money. Sedentary lifestyles, worsened by years of remote working and screen-heavy routines, aren’t helping either. But there’s a specific biological wrinkle for women: polycystic ovary syndrome (PCOS), which affects roughly one in ten women in the UK, significantly raises the risk of insulin resistance, the precursor to type 2 diabetes.
“Women with PCOS are at substantially higher risk, and many of them don’t even know they have it,” one endocrinologist recently noted in the British Medical Journal. “We’re catching these diagnoses late because nobody’s looking for them in young women.”
The symptoms are easy to miss or dismiss. Persistent fatigue, increased thirst, needing to wee more than usual, blurred vision, and slow-healing cuts are all red flags. The trouble is, those first few could describe half the population of overtired twentysomethings on any given Monday morning.
Early diagnosis makes an enormous difference. Caught soon enough, type 2 diabetes can be managed, and in some cases put into remission, through changes to diet and exercise. The NHS Low Calorie Diet Programme, which has seen participants lose significant weight and reverse their diagnoses, is open to newly diagnosed patients with a BMI over 27.
What makes this moment particularly important is the window it opens for prevention. Young women in their twenties still have decades ahead of them. The complications of poorly managed diabetes, including kidney disease, nerve damage, and increased cardiovascular risk, are not inevitable outcomes. They’re preventable ones.
The real question is whether GPs, and young women themselves, are paying close enough attention to spot the signs before they become something much harder to manage.
