Hyperemesis gravidarum is the severe end of pregnancy sickness. It can cause dehydration, weight loss, electrolyte disturbance and major disruption to physical and emotional wellbeing, and it deserves active treatment rather than being dismissed as “normal morning sickness”.
How clinicians assess severity
Assessment usually includes symptom duration, fluid intake, urine output, weight change, pulse, blood pressure and signs of dehydration. Blood and urine tests may be used to check electrolytes, kidney and liver function, infection and ketones. Ultrasound may be considered when dates are uncertain, symptoms are unusual or another pregnancy-related cause needs exclusion.
Treatment pathway
Care may begin with oral fluids and anti-sickness treatment, but day-care or hospital treatment may be needed when oral intake is not possible. Intravenous fluids, combinations of anti-sickness medicines, thiamine supplementation and thrombosis prevention may be considered according to severity and clinical risk. Repeated review is often more useful than waiting for symptoms to become extreme.
Nutrition, mental health and daily life
Small frequent intake, cold fluids, avoiding personal triggers and dietetic support can help, but dietary advice should not replace medical treatment. Severe sickness can affect sleep, work, relationships and mood. Emotional distress should be asked about directly and support offered without implying that symptoms are psychological.
Follow-up and recurrence planning
A written plan should explain which medicines to continue, how to step treatment up or down, and when to return urgently. People with previous hyperemesis may benefit from a pre-pregnancy or very early pregnancy plan because symptoms often recur.
Questions worth discussing at your consultation
- What signs show that I need day-care or hospital treatment?
- Which anti-sickness options are suitable for me?
- How will dehydration, weight and blood tests be monitored?
- What should I do if symptoms return after discharge?
