Which is a normal age-related change?
Decreased secretion of saliva
Increased acidity of saliva
Decreased gastric emptying
Increased peristalsis
The Correct Answer is C
A. Decreased secretion of saliva
This is not a normal part of aging; if present, it's often due to medications or illness.
B. Increased acidity of saliva
Salivary composition doesn’t change significantly with age; this is not a recognized normal change.
C. Decreased gastric emptying
Aging can slow down GI motility, leading to delayed gastric emptying, which can contribute to fullness or indigestion.
D. Increased peristalsis
GI peristalsis slows with age, increasing the risk of constipation, not increasing motility.
