Loss of Appetite in Pregnancy: Does It Predict Gender?

Food aversions, nausea, vomiting, changes in smell, reflux, tiredness, stress, and hormonal changes can all reduce interest in food during pregnancy. A temporary change in appetite is different from being unable to keep fluids down or eating very little for an extended period. Infections and digestive conditions can also cause poor appetite; examples include [Gastroenteritis](/conditions/gastroenteritis/) and [Gastritis](/conditions/gastritis/).

Appetite alone cannot identify a baby's sex. If you want to know, ask your maternity team which screening or imaging options are suitable for your stage of pregnancy and local care pathway.

Try small meals or snacks at regular intervals rather than waiting for a strong appetite. Choose foods that are easier to tolerate, keep simple options available, and sip fluids regularly. Cold foods may be easier if cooking smells trigger nausea. Include nourishing choices from the food groups you can manage, and mention ongoing nausea or vomiting at an antenatal appointment before starting supplements or medicines.

Keep track of what you can eat and drink, along with vomiting, pain, fever, or weight changes. This gives a clinician useful detail when deciding whether the appetite change fits common pregnancy symptoms or needs assessment for another condition, such as [Influenza](/conditions/influenza/) or [Depression](/conditions/depression/).

Contact your maternity team or a clinician promptly if you cannot keep fluids down, are passing very little urine, feel faint or unusually weak, have severe or persistent abdominal pain, develop a fever, or notice blood in vomit or stool. Seek urgent help for confusion, difficulty breathing, or severe dehydration. A clinician can check you and the pregnancy, review medicines, and look for causes such as [Hepatitis A](/conditions/hepatitis-a/) or a [Peptic Ulcer](/conditions/peptic-ulcer/).

Ask what level of appetite change is expected for your stage of pregnancy, how to manage nausea safely, and which symptoms should prompt same-day advice. You can also ask how hydration and nutrition will be monitored, whether a medicine or supplement could be affecting your appetite, and which reliable options are available if you want information about the baby's sex.
