What change occurs in older adults' stomachs?

As individuals age, there is a notable decrease in the production of digestive juices in the stomach. This reduction affects various components of digestion, including the production of gastric acid and digestive enzymes.

Lower levels of gastric acid can lead to changes in how food is processed, potentially causing issues such as decreased nutrient absorption, indigestion, or discomfort after eating. In older adults, these physiological changes are part of the natural aging process and can have significant implications for nutritional health, since sufficient digestive juices are essential for breaking down food and absorbing nutrients.
