(1) Duration and Onset:
- How long has the vomiting been occurring? Did it start early in pregnancy or more recently?
(2) Frequency and Severity:
- How many times per day does she vomit? Is she able to keep food or liquids down?
(3) Associated Symptoms:
- Does she experience any associated symptoms like abdominal pain, headaches, dizziness, fever, or weight loss? These could suggest a more serious condition.
(4) Past Medical History:
- Any previous history of hyperemesis gravidarum in a prior pregnancy, gastrointestinal disorders, diabetes, or thyroid issues?
(5) Hydration Status:
- Has she been able to maintain adequate fluid intake? Any signs of dehydration such as reduced urine output or dark urine?
(6) Medications and Allergies:
- Is she taking any medications or supplements, such as iron supplements or multivitamins, which could contribute to nausea?
