New research conducted across 19 high-income countries has shed light on the significant impact of a type 2 diabetes diagnosis on life expectancy. This study reveals that individuals diagnosed with type 2 diabetes at different ages face varying degrees of reduction in their life expectancy, with profound implications for public health strategies and prevention efforts.
The study, published in The Lancet Diabetes & Endocrinology, underscores the urgency of addressing the growing prevalence of type 2 diabetes, particularly among younger adults, as lifestyle factors like obesity, poor diet, and sedentary behavior continue to contribute to its rise. In 2021, an estimated 537 million adults worldwide had diabetes, emphasizing the pressing need for effective prevention strategies.
One of the key findings of this research is the stark contrast in life expectancy based on the age of diagnosis. An individual diagnosed with type 2 diabetes at the age of 30 could potentially see their life expectancy reduced by as much as 14 years. Even those diagnosed at age 50 may face a reduction of up to six years in their life expectancy.
The research team, led by scientists from the University of Cambridge and the University of Glasgow, examined data from two major international studies comprising a total of 1.5 million individuals. Their analysis revealed a clear trend: the earlier the diagnosis, the greater the reduction in life expectancy. On average, every decade earlier in life that type 2 diabetes is diagnosed is associated with a four-year reduction in life expectancy.
To illustrate the impact more concretely, individuals diagnosed with type 2 diabetes at ages 30, 40, and 50 were estimated to die, on average, about 14, 10, and 6 years earlier, respectively, than those without the condition. These estimates showed slightly higher numbers for women compared to men.
The study also highlighted the leading causes of reduced life expectancy among individuals with type 2 diabetes, primarily “vascular deaths” related to conditions such as heart attacks, strokes, and aneurysms. Cancer and other complications further contributed to the decreased life expectancy associated with this condition.
Professor Emanuele Di Angelantonio from the University of Cambridge emphasized the evolving demographic of type 2 diabetes, increasingly affecting younger individuals. This shift calls for a comprehensive approach that includes early identification of at-risk individuals and tailored interventions to mitigate their risk, whether through behavioral changes or medication.
Dr. Stephen Kaptoge, also from the University of Cambridge, stressed the importance of societal structural changes, such as improvements in food manufacturing and the built environment to promote physical activity. Preventing or delaying the onset of type 2 diabetes is paramount given its significant impact on individuals’ lives.
In conclusion, this research underscores the gravity of the type 2 diabetes epidemic and the need for proactive measures to address its rising prevalence, especially among younger adults. Early detection, lifestyle modifications, and broader societal changes are crucial components of a comprehensive strategy to mitigate the life expectancy reduction associated with this condition.

Frequently Asked Questions (FAQs) about Type 2 Diabetes Life Expectancy
What is the key takeaway from the research on type 2 diabetes and life expectancy?
The key takeaway is that the age at which an individual is diagnosed with type 2 diabetes significantly impacts their life expectancy. Earlier diagnoses result in greater reductions in lifespan.
How much can life expectancy be reduced for someone diagnosed with type 2 diabetes at different ages?
Individuals diagnosed at age 30 could see their life expectancy fall by as much as 14 years, while those diagnosed at age 50 might face a reduction of up to six years in their life expectancy.
What factors contribute to the increasing prevalence of type 2 diabetes?
The rising prevalence of type 2 diabetes is largely driven by factors such as obesity, poor diet, and sedentary behavior. These lifestyle choices contribute to a higher risk of developing the condition, particularly among younger adults.
What are the leading causes of reduced life expectancy among individuals with type 2 diabetes?
The majority of the reduction in life expectancy associated with type 2 diabetes is due to ‘vascular deaths,’ including heart attacks, strokes, and aneurysms. Additionally, complications like cancer contribute to the decreased life expectancy.
What strategies are recommended to address the impact of type 2 diabetes on life expectancy?
Preventative measures include early identification of at-risk individuals, behavioral changes, and medication when necessary. Structural changes at the societal level, such as improvements in food manufacturing and creating environments that promote physical activity, are also recommended to tackle this issue.
Where can I find the full research study on this topic?
The full research study, titled “Life expectancy associated with different ages at diagnosis of type 2 diabetes in high-income countries,” was published in The Lancet Diabetes & Endocrinology on September 11, 2023, with DOI: 10.1016/S2213-8587(23)00223-1.
What organizations supported the research conducted in this study?
The research team from the University of Cambridge received support from various organizations, including the Medical Research Council, British Heart Foundation, Health Data Research UK, and NIHR Cambridge Biomedical Research Centre.

Early diagnosis = shorter life. Scary! We need 2 eat better & exercise!
Anyone else curious about the gender diff in life expectancy? It’s in there, but I want more details.
Vascular deaths = major prob for diabetics. Need more research on this!
fascinating stuff! the way they show how diabetes affects your life expectency is mind-blowing! its important info for all.
I wonder if these findings apply worldwide? Not just high-income countries.
