A 20-year-old female presents with weakness, severe nausea, vomiting, and missed menstruation cycles. What condition should you suspect?

The symptoms presented—weakness, severe nausea, vomiting, and missed menstruation cycles—are classic indicators of early pregnancy complications. Hyperemesis gravidarum, specifically, refers to severe nausea and vomiting during pregnancy that can lead to dehydration and weight loss. It is characterized by these symptoms occurring to an extent that may necessitate medical intervention.

The missed menstruation cycles are particularly significant, as they suggest a potential pregnancy. The combination of severe nausea and vomiting alongside this history raises a strong suspicion for hyperemesis gravidarum. Recognizing this condition is vital because it can have serious health implications for both the mother and the fetus if not properly managed.

While ectopic pregnancy could also cause similar symptoms, it typically presents with additional signs such as abdominal pain or tenderness and may progress to more severe consequences if not diagnosed promptly. Gestational diabetes usually does not present until later in pregnancy and would not cause missed periods or severe nausea and vomiting at this early stage. Pelvic inflammatory disease could cause nausea and abdominal pain but would not typically cause missed periods in the way that pregnancy-related conditions would.

Thus, the presented symptoms align most closely with the diagnosis of hyperemesis gravidarum, making it the most logical condition to suspect in this scenario
