February 11, 2026 | 00:19A major new study conducted by scientists from the University of Surrey (UK) and the University of Lille (France) has found that type 2 diabetes and hypertension (high blood pressure) share common genetic factors that may explain why these diseases so often occur together in the same individuals. The findings were published in Nature Communications and open the way toward more personalized prevention and treatment strategies for both conditions.

Researchers analyzed more than 1,300 genetic variants associated with type 2 diabetes and blood pressure regulation and identified several clusters of DNA variants that influence metabolism, pancreatic function, fat distribution, and vascular health. This suggests that in some individuals, inherited traits simultaneously increase the risk of developing both diabetes and hypertension.

The team then applied these genetic profiles to data from more than 450,000 participants in the UK Biobank, a large-scale database containing genetic and medical information. The analysis showed that individuals with high genetic risk in certain clusters were indeed more likely to develop both type 2 diabetes and elevated blood pressure.

The study’s authors emphasize that this approach helps clarify the biological pathways through which the same inherited predisposition can lead to different diseases — a key step toward the medicine of the future. Because genetic information remains stable throughout life, it can be used at the time of an initial diagnosis — for example, in a patient with diabetes — to predict the risk of hypertension and guide more targeted preventive measures.

Although both conditions are influenced by lifestyle and age, scientists note that shared genetic factors help explain their frequent coexistence within a single clinical picture. In the future, this knowledge may accelerate the development of personalized prevention and treatment strategies, where genetic insights enable doctors to prevent complications before they arise.
