Food for loss of appetite: what to eat and when to seek help

When your appetite is low, choose small, nourishing portions that are easy to eat, sip fluids regularly, and seek medical advice if the problem persists or comes with warning signs. You do not need to wait for a strong feeling of hunger: a few bites at regular intervals may be easier than a full plate. Choose foods that provide energy and protein, such as yoghurt, eggs, soup with lentils or chicken, cheese, nut butter, beans, rice, or a smoothie.

Loss of appetite means you feel less interested in food or become full sooner than usual. It can occur during an infection, nausea, pain, constipation, medication use, stress, low mood, or changes in taste or smell. COVID-19, influenza, gastroenteritis, hepatitis A, gastritis, and peptic ulcer can present with reduced appetite alongside other symptoms. Depression can also present with appetite changes. Pancreatic cancer may present with appetite loss, but appetite loss alone does not identify its cause. A clinician considers the whole pattern, including weight change, abdominal symptoms, bowel habits, fever, mood, medicines, and how long the change has lasted.

Try cool or room-temperature foods if cooking smells are unappealing. Keep simple snacks within reach, eat slowly, and use a small bowl or plate. Fortify familiar food with milk powder, grated cheese, olive oil, avocado, or nut butter when suitable for you. Take frequent sips of water or an oral rehydration drink if vomiting or diarrhoea is present; ask a pharmacist which option fits your situation. Avoid filling up on large drinks immediately before meals. Do not start supplements or stop prescribed medicines without discussing them with a clinician.

Arrange medical advice if appetite loss continues, keeps returning, causes unplanned weight loss, or makes it difficult to maintain food and fluid intake. Seek urgent help for confusion, fainting, severe weakness, trouble breathing, severe or worsening abdominal pain, blood in vomit or stool, or signs of significant dehydration such as very little urine. Prompt assessment is also sensible when appetite loss occurs with yellowing of the skin or eyes, persistent vomiting, a high fever, or a marked change in mood. Children, older adults, and people with diabetes or other long-term conditions may need earlier advice.

You could ask: What might be affecting my appetite? Could any of my medicines be contributing? Which foods and drinks are appropriate for my symptoms or medical conditions? Do I need checks for dehydration, nutritional problems, infection, or abdominal causes? What changes should prompt urgent care? Bring a short record of what you manage to eat and drink, associated symptoms, medicines, and any weight change.
