Why it happens

Pregnancy-related nausea is common and can occur at any time of day. Hormonal changes, smell sensitivity and slower digestion may contribute.

Practical self-care

Small frequent meals, bland foods, regular fluids and avoiding personal triggers may help. Ask before using any medicine, supplement or herbal remedy.

When symptoms are more severe

Repeated vomiting, inability to keep fluids down, dark urine, dizziness or weight loss can indicate dehydration or hyperemesis gravidarum and should be assessed.

When to seek urgent careVomiting blood, fainting, severe abdominal pain, confusion or inability to keep fluids down requires urgent medical care.
Medical note: Individual assessment is essential when symptoms are new, severe, persistent or changing.
