Losing 5% of one's total body weight can result in clinically significant physiologic changes. For example, losing a little weight can reduce heartburn, knee pain, blood pressure, and diabetes risk. Losing 5% of one's body weight may also lead to better sexual function, more restorative sleep, extra energy, and more self-esteem. To reach a 5% reduction in total body weight, it helps to exercise; eat a healthy diet rich in lean proteins, whole grains, fruits, vegetables, legumes, nuts, and seeds; and get enough sleep.

The human body has hundreds of lymph nodes, one part of the immune system that helps defend the body against health threats. They aren't usually noticeable, but they are always working to deal with potential health problems.

Some medical alert systems now have advanced technology that integrates monitoring services with a smartphone, smart watch, or smart speaker. The services aren't cheap. They range from $20 to $50 per month, depending on the company and any additional services (such as fall detection). There may also be fees for activation and equipment (up to a few hundred dollars). The alternative is getting an alert system that isn't monitored, such as free "panic button" apps for smartphones or a smart watch that can notify relatives in an emergency.

Some medication instructions are vague and confusing. Examples include "take once daily," "take with food," and "take with water." When someone is unsure exactly how to take a medication, even if it's already been explained, it's best to ask for clarification.

It may also be helpful to ask a pharmacist for the directions, either when picking up a medication or on a later call.

The reason for weight gain isn't always as obvious as inactivity or a poor diet. Weight gain can stem from many other causes. For example, it might reflect age-related physiological changes such as muscle loss, poor sleep, or changes in sex hormone levels; underlying conditions such as diabetes or sleep apnea; side effects from taking certain medications, such as antidepressants or beta blockers; or possibly the effects of eating late at night or the makeup of gut bacteria. Recent or excessive weight gain warrants a visit to a doctor to help pinpoint the issue.
