Depression and lack of appetite: what to know

Depression can affect the signals that influence hunger, pleasure and motivation. Food may seem unappealing, meals may be forgotten, or preparing and eating may feel like too much effort. Some people have the opposite pattern and eat more. Appetite loss by itself does not establish depression; physical illness, medicines, nausea, anxiety and other problems can also change eating. A clinician considers mood, sleep, energy, concentration and changes in weight or hydration.

Tell someone you trust what you are finding difficult and arrange a health assessment if the change continues. Try small, manageable meals or snacks at regular times, choose familiar nourishing foods, and keep fluids available. If cooking is hard, accept help with shopping or preparation. Record what you manage to eat and drink, along with nausea, mood and medicines, so the clinician can identify patterns. Do not start supplements without checking that they are suitable for you.

Seek prompt care if you cannot keep fluids down, feel faint or confused, become very weak, or are unable to maintain basic nutrition. Arrange an appointment for ongoing appetite loss, unintended body changes, or depression symptoms. Get urgent help for suicidal thoughts or inability to stay safe by contacting local emergency services or attending the nearest emergency department.

Ask what might be affecting appetite, whether medicines or physical conditions should be checked, how to protect nutrition, and which depression treatments are appropriate if mood symptoms are present.
