Changes with Aging

As we get older, there are many different changes that happen in our bodies that affect our relationship with food. This article will explore these different changes that take place and how it can affect a person’s perspective about food. The focus will be on changes specifically in gastrointestinal functions of the body.

The Clinical Significance of Gastrointestinal Changes With Aging
Purpose of review with the graying of the world’s population, there is an increased interest in the physiological effects of aging. This review examines the physiological changes of the gut with aging and their clinical significance. Recent findings Changes with aging in the gastrointestinal tract are variable, but in some cases they are responsible for a variety of symptoms. Thus, alterations in taste and smell, gastric motility, intestinal overgrowth and changes in gastrointestinal hormone release are the basis of the physiological anorexia of aging. Alterations in swallowing lead to silent aspiration. Changes in gastric emptying play a role in postprandial hypotension. Changes in gastrointestinal function can lead to constipation and fecal incontinence. Weakening of the colonic muscular wall produces diverticula. Achlorhydria is associated with malabsorption of some forms of iron and calcium. Vitamin D malabsorption aggravates the hypovitaminosis D that is so common in older persons. Changes in probiotics can lead to diarrhea and altered immune system. In the liver, aging is associated with delayed drug metabolism. Summary Changes in the physiology of the gut play a role in the anorexia of aging, aspiration pneumonia, postprandial hypotension, constipation and fecal incontinence.
The ability of the gastrointestinal tract to function at its best is critical to one’s health. As we age changes occur that affect our relationship with food. The smell and taste of our food can become less appealing. The lack of stomach acid can affect the breakdown of food into its basic components. Which can lead to malabsorption and changes in bowel habits, poor immune function, as well as silent aspiration.

Gastrointestinal changes are critical to a person’s health and can lead to problems such as changes in bowel habits, poor immune function, and silent aspiration. Overall changes in the liver, probiotics, and gut composition can have significant effects on a person’s health and digestion.
