Even slightly elevated blood sugar levels—a condition known as pre-diabetes—may raise the risk of cardiovascular problems. But attention to weight loss and greater use of medications to lower blood pressure and cholesterol appear to reduce the risk.

Approximately 88 million Americans—more than one in three—have prediabetes, a condition in which the average amount of sugar in the blood (glucose) is high but not high enough to be diagnosed as diabetes. Among people who develop prediabetes, older ones are less likely than younger ones to eventually develop full-blown diabetes. Still, they should have their glucose levels checked, as prediabetes can put them at high risk for heart attack and stroke.

Silent heart attacks often go unnoticed because they don't produce any symptoms or only mild symptoms that are mistaken for something else, such as heartburn or muscle pain. They are thought to make up from 20% to 60% of heart attacks and can raise risk of a future heart attack or related problem. Both women and men are at substantial risk. Making lifestyle changes and being proactive about managing risk factors for heart disease can help prevent future heart-related problems.

Some older adults feel cold frequently. This may result from age-related physical changes or an underlying condition. Examples of underlying conditions that might make a person feel cold include anemia, an underactive thyroid, diabetic neuropathy, peripheral artery disease, or Raynaud's phenomenon. People who experience coldness that interferes with their daily activities or sleep should talk to a doctor about it.

Periodontal disease, the leading cause of adult tooth loss, may increase the risk of diabetes, heart disease, and dementia.

Type 2 diabetes is a major cause of vision loss and blindness, kidney failure requiring dialysis, heart attacks, strokes, amputations, infections, and even early death. Research suggests that a healthy lifestyle can prevent diabetes from occurring in the first place, and even reverse its progress.
