A study published in the journal Circulation suggested fluctuations in weight and other health metrics could raise the risk of these life-threatening conditions.
The study analysed more than 6,700,000 people in the Korean National Health Insurance System who did not have diabetes, high blood pressure, or high cholesterol, or a history of heart attacks at the time the study started.
All the participants had at least three medical exams between 2005 and 2012, during which doctors recorded their weight, blood sugar, blood pressure, and total cholesterol.
An average of 5.5 years later, the people with the most fluctuation in these numbers were found to be 127 percent more likely to die, 43 percent more likely to have a heart attack, and 41 percent more likely to have a stroke, compared to those with stable measurements.
