A new Korean study recently examined how fluctuating weight and other factors might affect certain health risks. This was done by collecting data from over 6.7 million healthy individuals. At the time of the study, none of the participants had diabetes, high cholesterol, high blood pressure, or a history of heart attacks.
After an eight-year study period, it was found that people with the greatest weight fluctuations – as well as significant changes in total cholesterol, systolic blood pressure, and blood glucose – were significantly more likely to have had a stroke or heart attack. This was compared to people who had relatively stable measurements. The study also found that those with the greatest fluctuations had a 127% higher risk of death, a 43% higher risk of heart attack, and a 41% higher risk of stroke.
These findings were published in the journal Circulation on October 1, 2018.
