Definition
- Loss of appetite (anorexia) is a common symptom in children.
- A transient loss of appetite is often associated with acute illness.
- Prolonged loss of appetite, when associated with poor weight gain or weight loss, may signify a serious or chronic illness.
- In infants, it is difficult to differentiate between loss of appetite and poor feeding.
- This is distinct from, but closely related to, failure to thrive.
