The following is a list of age related changes that may affect how much your family member or client eats or drinks:

  • loss of taste and smell causing food to taste bland
  • loss of the awareness of thirst
  • loss of muscle mass
  • loss of bone mass
  • decline in the rate energy is used
  • slowing of how fast the stomach empties
