Diabetes is bad news for ageing. Overall, diabetes is the 7th leading cause of death in 2016, and the number of people with diabetes has gone up almost 400% from 1980 to 2014! Since seniors have a much higher risk of diabetes, they should take particular care to get tested regularly. Most importantly, if you are diagnosed with diabetes or pre-diabetes, you should follow your doctor’s advice and take steps to change your lifestyle immediately.
