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.

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.

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

American adults consume an average of 77 grams (almost 20 teaspoons) of sugar per day. A little extra sugar may seem harmless, but the amounts can add up and, over time, contribute to a variety of health issues, like obesity, diabetes, and heart disease. Avoiding high-sugar foods by reading labels and cutting out sugar-sweetened beverages are the best ways to lower intake of added sugar.

A high intake of sugar is linked to an increased risk of obesity, type 2 diabetes, cardiovascular disease, and certain cancers. But whether some sugars are healthier (or worse) than others remains a question of interest to many.
