What Is Appetite Loss?
Appetite loss, also called decreased appetite, is a reduced desire to eat. It may develop gradually or suddenly and can be caused by illness, medications, emotional stress, aging, or chronic medical conditions. While temporary appetite loss is common during short-term illnesses, persistent loss of appetite may require medical evaluation.
Without adequate nutrition, prolonged appetite loss can lead to weight loss, weakness, dehydration, and malnutrition.
