A note from Cleveland Clinic
A loss of appetite is usually a temporary symptom. Once you and your healthcare provider uncover the cause of your decreased appetite, you’ll feel better and the symptom will go away. Your body is constantly changing as you get older, so some foods that you used to love might not be your favorite today or tomorrow. If you experience a sudden loss of appetite, changes to your mood or weight, don’t delay and contact your healthcare provider. The sudden onset of symptoms can be a sign of an underlying condition that needs treatment.
