Hyperemesis gravidarum due to thyrotoxicosis

Area of Science:

• Obstetrics and Gynecology
• Endocrinology

Background:

• Hyperemesis gravidarum (HG) is severe nausea and vomiting in pregnancy.
• The etiology of HG is often multifactorial and can be challenging to diagnose.

Observation:

• A case of HG at 9 weeks' gestation presented with no identifiable cause.
• The patient required intravenous feeding for life preservation.
• Following nutritional support, the patient developed a thyrotoxic crisis.

Findings:

• The thyrotoxic crisis was successfully diagnosed and treated.
• The pregnancy continued to term with a described outcome.
• Vomiting in pregnancy can be a presenting sign of thyrotoxicosis.

Implications:

• Clinicians should consider thyrotoxicosis in the differential diagnosis of unexplained hyperemesis gravidarum.
• Early recognition and management of thyrotoxicosis are vital for managing HG.
• This case highlights the importance of a comprehensive diagnostic approach in complex obstetric cases.
