Why does depression cause loss of appetite?

Loss of Appetite is a very common presentation of Depression. Food may seem unappealing, hunger may be easy to miss, or shopping and cooking may feel like too much effort. Some people also notice nausea, changes in taste, or eating at irregular times when their routine has shifted. A poor appetite can make low energy and concentration worse, especially when meals are skipped. Appetite loss is not specific to depression: infection, digestive problems, pain, medicines, grief, and other conditions can be involved. A healthcare professional can consider changes in mood alongside physical symptoms and eating habits.

Aim for small, regular opportunities to eat rather than waiting for a strong appetite. Keep simple foods and drinks available, and choose options that need little preparation when energy is low. If possible, eat with another person or ask for practical help with shopping and meals. Set reminders for meals and fluids, especially if you lose track of time. Write down appetite changes, nausea, weight changes you have noticed, medicines, and mood symptoms for your appointment. Do not make major medication changes without medical advice.

Contact a clinician if loss of appetite continues, you are struggling to drink or eat enough, or it comes with persistent low mood and reduced interest in life. Seek prompt assessment for severe abdominal pain, repeated vomiting, difficulty swallowing, blood in vomit or stool, confusion, or fainting. Get urgent help immediately if you have thoughts of harming yourself, have a plan to do so, or feel unable to stay safe; contact emergency services or go to the nearest emergency department.

Ask whether depression, a medicine, or another medical issue could be affecting your appetite. You may also ask for practical nutrition support, ways to manage nausea, and a treatment plan that addresses both mood and eating.
