Which finding is NOT associated with gestational trophoblastic disease?

The finding not associated with gestational trophoblastic disease is decreased nausea. In fact, patients with gestational trophoblastic disease, including conditions such as hydatidiform mole, often experience increased levels of human chorionic gonadotropin (hCG) due to the abnormal proliferation of trophoblastic tissue. This elevated hCG can lead to significant symptoms of nausea and vomiting, commonly referred to as hyperemesis gravidarum, which may be much worse than typical morning sickness experienced in healthy pregnancies.

Gestational trophoblastic disease is also notable for a larger-than-normal uterus, as the abnormal growth of the tissue can cause excessive enlargement. In addition, other associated symptoms include elevated hCG levels which are used as a key diagnostic marker. Therefore, the absence of decreased nausea in this context indicates a deviation from what is usually expected with gestational trophoblastic disease.
