Type 2 diabetes, once considered a disease of older age, is now showing a 'worrying increase' in women as young as their 20s, according to recent findings. Researchers at Imperial College London analyzed NHS data from 2011 to 2024 and observed a 69% rise in new type 2 diabetes diagnoses among women aged 20-29. This contrasts with a 43% increase in men of the same age group, indicating that women are driving the trend in younger populations.
Type 2 diabetes occurs when the body either becomes resistant to insulin or doesn't produce enough of the hormone, leading to elevated blood sugar levels. The long-term complications can be severe, including damage to blood vessels, which can result in heart disease, stroke, foot problems like ulcers and infections, and vision loss, including diabetic retinopathy and blindness. Developing the condition at a young age means decades of elevated blood sugar, allowing gradual damage to the eyes, kidneys, nerves, and heart arteries.
Diabetes UK reports that type 2 diabetes contributes to 184 amputations, over 1,010 strokes, 700 heart attacks, and 3,340 cases of heart failure weekly in the UK. The onset of symptoms can be subtle and easily mistaken for other issues. These include persistent thirst, frequent urination, fatigue not relieved by sleep, blurred vision, and slow-healing cuts. Medical professionals note that young women, in particular, may attribute these signs to stress or overwork, delaying diagnosis.
Specific indicators for women to be mindful of include recurrent episodes of thrush and repeated urinary tract infections, which can be consequences of elevated sugar levels in the urine promoting bacterial growth. Conditions like polycystic ovary syndrome and gestational diabetes also carry a higher risk of developing type 2 diabetes and are often diagnosed in this age group. Obesity and lifestyle factors are increasingly linked to the rise in diagnoses, with the current environment often promoting rapid consumption of readily available, highly palatable foods.
However, there is hopeful news regarding the condition's manageability. The groundbreaking DiRECT trial demonstrated that type 2 diabetes can be reversed, particularly in younger individuals. In the trial, 46% of newly diagnosed participants achieved remission within a year by following a low-calorie diet of soups and shakes for up to five months. Success rates were correlated with weight loss, with 57% of those losing 10-15kg reversing their condition. This approach now informs the NHS's Type 2 Diabetes Pathway to Remission programme.
Experts advise that instead of lecturing about diet, concerned individuals should encourage younger relatives to get screened. A simple blood test can provide a definitive diagnosis. Early detection is crucial, as type 2 diabetes is among the serious diseases that can be effectively managed and potentially reversed when caught in time, especially in younger individuals.
