What is a potential result of overhydration in elderly residents?

Overhydration in elderly residents can lead to edema, which is the accumulation of excess fluid in the body's tissues. This can occur for several reasons, including the body's decreased ability to manage fluid balance as people age, compromised kidney function, or heart issues that may limit the body’s ability to effectively expel excess water. Edema often manifests as swelling in the legs, ankles, or feet, and may even affect other areas of the body.

Weight loss, dehydration, and diarrhea are not results of overhydration. Weight loss typically occurs due to a caloric deficit, dehydration is a lack of sufficient fluid intake, and diarrhea is characterized by increased fluid loss from the gastrointestinal tract. Therefore, edema is the primary concern when discussing the risks associated with excessive fluid intake in the elderly.
