How this protocol works

In plain language

Hyperemesis gravidarum (HG) is severe nausea and vomiting during pregnancy that goes beyond typical "morning sickness." It causes dehydration, weight loss (>5% of pre-pregnancy weight), electrolyte imbalances, and can require hospitalization. HG affects about 0.5-2% of pregnancies and usually begins around weeks 4-6, peaks at 9-13 weeks, and improves by week 20 for most women (though some have symptoms throughout pregnancy).

CRITICAL: Hyperemesis gravidarum requires medical care. If you cannot keep down fluids, are losing weight, urinating very little, or feeling faint, seek medical attention. Treatment may include:

  • IV fluids: Essential for rehydration
  • Anti-nausea medications: Ondansetron, metoclopramide, promethazine, doxylamine+B6 (Diclegis)
  • Hospitalization: For severe cases requiring IV nutrition
  • Thiamine supplementation: Critical to prevent Wernicke encephalopathy

THIS IS NOT "JUST MORNING SICKNESS." HG is a serious condition that can affect you and your baby. Don't suffer in silence.

Vitamin B6 (Pyridoxine)* is the first-line supplement for pregnancy nausea. It's safe and effective. Often combined with doxylamine (antihistamine) as prescription Diclegis/Bonjesta.

Ginger* has been studied in multiple trials for pregnancy nausea and shown to be safe and effective. Can be taken as capsules, tea, or candies.

Thiamine (B1)* supplementation is CRITICAL in HG. Prolonged vomiting can cause thiamine deficiency, leading to Wernicke encephalopathy (a neurological emergency). All HG patients should receive thiamine.

Electrolyte replacement* addresses losses from vomiting.

Prenatal vitamins*: If standard prenatals worsen nausea, switch to iron-free, gummy, or smaller formulations. Don't stop taking prenatals - work with your provider to find a tolerable form.

Expected timeline: Many women feel improvement by weeks 16-20. Supplements help manage symptoms but don't "cure" HG. The condition runs its course with proper supportive care.
