Normalising blood glucose in prediabetes may cut cardiovascular risk by half study finds
Research indicates that normalising blood glucose levels in people with prediabetes may reduce their risk of cardiovascular disease by about half. The study suggests that early intervention through lifestyle changes or treatment could significantly improve heart health outcomes.
A recent study has found that individuals with prediabetes who manage to bring their blood glucose levels back into the normal range may cut their risk of developing cardiovascular disease by around 50 percent compared with those whose glucose remains elevated. Prediabetes is a condition where blood sugar levels are higher than normal but not high enough to be classified as diabetes. It is known to increase the risk of type 2 diabetes and associated complications.
The research showed that normalising blood glucose was linked to significantly lower rates of heart attacks, strokes and other major cardiovascular events. This suggests that early management of prediabetes can have meaningful benefits beyond preventing progression to diabetes, extending to overall cardiovascular health.
Experts say lifestyle changes such as eating a balanced diet, increasing physical activity, losing excess weight and improving sleep quality can help many people reduce their blood glucose levels. For some, medication may also be recommended to support glucose control based on individual health profiles and medical guidance.
The study adds to growing evidence that prediabetes should not be ignored as a benign condition. Health care professionals have long cautioned that even moderately high blood glucose can damage blood vessels and increase inflammation, contributing to heart disease risk. Interventions that achieve normal glucose levels may therefore provide protective effects.
Healthcare providers increasingly emphasise early screening for prediabetes, especially for people with risk factors such as family history, obesity or a sedentary lifestyle. Identifying those at risk and guiding them toward effective management can help reduce the burden of cardiovascular disease in the population.
While the study did not establish that normalising glucose alone is the sole cause of reduced cardiovascular risk, it strengthens the case for proactive measures in early disease stages. Further research may help clarify the best strategies for achieving and maintaining normal blood glucose levels in diverse populations.
For individuals with prediabetes, the findings serve as motivation to work with healthcare professionals on lifestyle modifications and monitoring plans. Early and sustained action could yield significant health benefits and reduce long-term risks related to heart and blood vessel disease.
