Loss of appetite in the third trimester

As the baby and uterus grow, a full meal may feel uncomfortable and reflux can become more noticeable. Breathlessness, constipation, tiredness, altered taste and lingering nausea may also reduce interest in food. These explanations do not account for every case: influenza, COVID-19, gastroenteritis, gastritis or another condition can cause appetite loss at any stage.

Pay attention to fluids, urination, vomiting, abdominal pain, headache, vision changes, swelling, fever and fetal movement. Mention a sustained change in appetite at your maternity appointment or sooner if you feel unwell.

Choose small meals and snacks rather than large portions, remain upright after eating, and avoid foods that clearly trigger reflux. Sip fluids between meals and keep nutrient-dense options close by, such as yoghurt, eggs, beans, soup or nut butter if suitable for you. Rest and ask someone to help with preparation.

Use only medicines or supplements approved by your maternity clinician. If intake is falling or vomiting is increasing, call for advice; treatment may be needed to protect hydration and nutrition.

Seek urgent maternity help for reduced or changed fetal movement, vaginal bleeding, severe abdominal pain, severe headache, vision changes, chest pain, trouble breathing, fainting, confusion or inability to keep fluids down. Prompt advice is also needed for very little urine, fever, repeated vomiting or rapidly worsening weakness.

Ask whether reflux, pregnancy sickness, infection or another issue best explains the change, whether your hydration and growth checks are reassuring, and which foods or medicines are suitable before delivery.
