Living with Hydatidiform mole
A condition of the placenta in early pregnancy, in which women have repeat abnormal pregnancies called moles.
Understanding Hydatidiform mole
A mole is a mass early in pregnancy made of cells from an abnormally developed embryo and placenta. The first sign is often vaginal bleeding in the first trimester. Ultrasound may show many small sacs, like a bunch of grapes. A mole must be removed by surgery, typically by the end of the first trimester. After removal, there is up to a 20 percent chance that leftover tissue grows into a tumor that needs follow-up.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Vaginal bleeding in early pregnancy
- Enlarged uterus
- Nausea and vomiting
- Low red blood cells (anemia)
- Heavy, irregular periods (menometrorrhagia)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
