Registered Dietitian - Exam Topics Sample Questions

The proportion of water in the body is affected by





Correct Answer:
age.


the proportion of water in the human body changes significantly with age. water constitutes about 75% of the body weight in infants, which is considerably higher compared to adults. as individuals age, the percentage of bodily water decreases. this decline continues such that in elderly people, the water content can drop to as low as 50% of their body weight.

this reduction in water content with age can be attributed to several factors. firstly, the amount of muscle mass tends to decrease with age, and muscle tissue holds a high amount of water compared to fat tissue. as the proportion of muscle decreases and fat increases, the overall percentage of water in the body diminishes. secondly, the kidneys, which are critical in regulating water balance, become less efficient with age. this reduction in kidney function can affect the body's ability to retain water. moreover, elderly individuals often experience a decrease in the sensation of thirst, which leads to reduced fluid intake and can further lower the body's water content.

understanding the changes in water proportion through different stages of life is essential for managing health and wellness. adequate hydration is crucial for numerous bodily functions, including temperature regulation, joint lubrication, and the transportation of nutrients and waste products. as such, awareness of these age-related changes can help individuals, caregivers, and healthcare providers better monitor and manage fluid intake to promote optimal health outcomes across the lifespan.
