Diagnosing a molar pregnancy

This condition develops when placental tissue grows abnormally. Symptoms and hormone levels can raise concern, but the diagnosis depends on the overall clinical picture and the laboratory examination of tissue.

Ultrasound may show abnormal placental tissue, an unexpected pattern of development or no developing fetus, depending on the type of molar pregnancy. A blood test measures human chorionic gonadotropin, known as hCG. A level that does not match the expected pregnancy pattern needs interpretation with the scan and clinical findings.

Vaginal bleeding, severe nausea and vomiting, or a uterus measuring differently from expected can occur with a molar pregnancy. Each can have other causes in pregnancy, so none should be used alone to label the condition.

The usual next step is removal of the abnormal tissue under specialist care. The tissue is sent to pathology, and hCG blood tests continue afterward because the trend shows whether molar tissue remains active. Keep every scheduled blood test even if bleeding has stopped and you feel well.

Use the contraception plan recommended by the treating team during monitoring, since a new pregnancy raises hCG and can make the results difficult to interpret. Ask when attempting another pregnancy would be medically appropriate for your circumstances.

Seek urgent care for heavy vaginal bleeding, fainting, severe abdominal or pelvic pain, breathlessness, chest pain, confusion, or vomiting that prevents you from keeping fluids down. During follow-up, report renewed bleeding or other symptoms specified by your specialist rather than waiting for the next scheduled test.

Ask what the ultrasound and pathology show, how your hCG results will be monitored, where blood tests can be done and who will contact you with results. Also clarify which contraception is suitable, what symptoms require an urgent call, and what would happen if hCG stops falling or begins to rise.
