First-Line Treatment of Hyperemesis Gravidarum with Metabolic Disturbance
Hyperemesis gravidarum with metabolic disturbance is a severe form of pregnancy-related nausea and vomiting that results in clinically significant dehydration and electrolyte abnormalities. First-line management addresses both the metabolic consequences and the underlying nausea.
Clinical Goals
- Correction of dehydration and electrolyte abnormalities
- Absence of ketonuria on daily urine testing
- Return to tolerance of oral fluid and diet
Treatment Approach
The first-line protocol centres on supportive management — including targeted dietary and lifestyle modifications, intravenous fluid resuscitation, and correction of electrolyte and nutritional deficits. The complete structured regimen, including specific agents, monitoring parameters, and decision criteria, is available via the link below.
