Older adults

Definition

Older adults are individuals generally aged 65 and above. They often experience changes in digestive function due to the aging process.

5 Must Know Facts For Your Next Test

1. Older adults commonly experience decreased production of digestive enzymes, which can affect nutrient absorption.
2. The motility of the gastrointestinal tract often slows down in older adults, leading to issues like constipation.
3. Aging can result in a weakened lower esophageal sphincter, increasing the risk of gastroesophageal reflux disease (GERD).
4. Older adults may have a reduced sense of thirst, putting them at higher risk for dehydration and its impact on digestion.
5. Changes in taste and smell that accompany aging can influence dietary choices and nutritional intake among older adults.
