As individuals age, the digestive system undergoes several changes that can impact its function. The muscles of the esophagus may contract less forcefully, but this typically does not significantly hinder the movement of food to the stomach. In the stomach, the mucus membrane tends to thin, leading to decreased production of mucus, hydrochloric acid, and digestive enzymes, which can impair protein digestion and may contribute to conditions like chronic atrophic gastritis. The walls of the small intestine may atrophy, potentially affecting nutrient absorption. Additionally, reduced strength and tone of the muscles in the digestive tract can slow the movement of food, leading to issues such as constipation.
Despite these changes, the digestive system retains considerable functional reserve, and many age-related effects can be managed through dietary adjustments and lifestyle modifications.
