Hyperemesis Gravidarum

Hyperemesis Gravidarum (HG) is a severe form of nausea and vomiting of pregnancy characterized by intractable vomiting, weight loss, dehydration, and electrolyte imbalances. Unlike typical morning sickness, HG significantly impairs nutritional status and quality of life, often requiring clinical intervention.

The exact cause is multifactorial and remains incompletely understood. Theories focus on the hormonal surge of human chorionic gonadotropin (hCG) and estrogen, which stimulate the chemoreceptor trigger zone. Genetic predisposition (GDF15/IGFBP7 gene variants), psychological factors (historically debated), and immunological responses to the fetus are current areas of research.

HG involves a complex interplay between placental hormones and neuroendocrine signaling. High levels of hCG trigger the vomiting center in the medulla. Impaired gastric motility and changes in gastrointestinal flora contribute to symptoms. Metabolic shifts, such as ketosis and acid-base disturbances, exacerbate the cycle of nausea and vomiting.

HG affects approximately 0.3% to 2% of pregnancies. It is more common in younger women, primigravidas, and those with a personal or family history of the condition.

• History of HG in prior pregnancies
• Multiple gestation
• Molar pregnancy (hydatidiform mole)
• Hyperthyroidism
• History of motion sickness or migraines
• Nulliparity
• High body mass index (BMI)

A. Early Symptoms: Persistent nausea, increased sensitivity to odors.
B. Common Symptoms: Vomiting (>3 times/day), inability to retain liquids, weight loss (>5% of pre-pregnancy weight).
C. Advanced Symptoms: Ketosis, dehydration, hypotension, tachycardia.
D. Emergency Symptoms: Confusion (Wernicke’s encephalopathy), hematemesis, jaundice, severe abdominal pain.

Signs of dehydration (dry mucous membranes, decreased skin turgor), orthostatic hypotension, tachycardia, acetone breath, and localized tenderness in the epigastrium.

A. Clinical Assessment: Symptom duration and severity score (PUQE scale).
B. Laboratory Testing: Urinalysis, electrolytes, liver enzymes.
C. Imaging Studies: Pelvic ultrasound to rule out molar pregnancy/multiple gestation.
D. Functional Tests: Not routine.
E. Biopsy Findings: N/A.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Gastroenteritis, cholecystitis, appendicitis, hepatitis.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Assess hemoconcentration
Expected Findings: Elevated hematocrit
Interpretation: Dehydration Urinalysis
Type: Urine Test
Purpose: Assess ketones/hydration
Expected Findings: Positive ketones
Interpretation: Starvation state

Obstetric Ultrasound: Used to confirm gestational age and evaluate for trophoblastic disease or multiple gestation.

Gastroenteritis (acute infection), Peptic Ulcer Disease, Cholecystitis, Pancreatitis, and Hyperthyroidism. HG is a diagnosis of exclusion.

Wernicke’s encephalopathy, esophageal tears (Mallory-Weiss), acute renal failure, fetal growth restriction, and psychological trauma.

A. Lifestyle Modifications: Small, frequent meals; ginger supplements; trigger avoidance.
B. Preventive Measures: Prenatal vitamins (start prior to conception).
C. Medical Treatment: - Antiemetics: Ondansetron, Promethazine, Metoclopramide.

• Vitamins: Thiamine (B1) to prevent Wernicke’s.

Good prognosis with early intervention. Symptoms typically resolve by the second trimester, though some patients experience them until delivery.

Early initiation of antiemetics and prenatal vitamins.
