Loss of appetite during pregnancy

Pregnancy-related nausea, smell sensitivity, indigestion and reflux can make familiar foods unappealing. Constipation, tiredness, stress and changes in taste may add to the problem. An infection such as influenza, COVID-19 or gastroenteritis can also reduce appetite. Symptoms do not identify a single cause, so the stage of pregnancy and associated signs matter.

Notice whether nausea or vomiting prevents fluids, whether you have abdominal pain, fever, diarrhoea, urinary symptoms or headache, and whether you are managing your usual activities. Tell your maternity team about ongoing symptoms.

Take frequent small sips of water and try bland or cool foods if smells trigger nausea. Small meals and snacks may be easier than a full plate; include foods with protein and energy when tolerated. Keep simple options nearby and rest. Ask your maternity clinician before taking an anti-sickness medicine, supplement or herbal product.

Continue prescribed prenatal medicines unless your clinician advises otherwise. If vomiting or poor intake is making daily life difficult, contact your maternity service rather than waiting for the next routine visit.

Seek urgent maternity or medical help if you cannot keep fluids down, have very little or dark urine, feel faint or confused, develop severe abdominal pain, fever, blood in vomit, vaginal bleeding, severe headache or vision changes. Contact your maternity team for persistent vomiting, worsening weakness or concern about your baby’s movements.

Ask whether your symptoms suggest pregnancy sickness, reflux, infection or another problem; whether you need hydration or blood tests; and which foods, supplements and medicines are suitable at your stage of pregnancy.
