When is morning sickness too much?
If you can’t keep fluids down for 24 hours, it isn’t “just morning sickness”.
Medically reviewed by Dr. Christopher Sterling, obstetrician ·
The short answer
Contact a doctor or midwife if you can’t keep food or fluids down for 24 hours, have very dark urine or haven’t passed urine for 8 hours, feel dizzy or weak, or vomit blood. This may be hyperemesis gravidarum — a serious but treatable condition.
Why it matters
Most pregnancy nausea is unpleasant but harmless. Hyperemesis gravidarum is different: severe, persistent vomiting that leads to dehydration and weight loss.
Many people suffer at home because they think they must just put up with it. There are anti-sickness medicines that are safe in pregnancy, and IV fluids if needed.
What to do
- For ordinary nausea: small frequent meals, plain snacks, sip fluids, try ginger.
- Get help if you can’t keep fluids down for 24 hours or have signs of dehydration.
- Ask about anti-sickness medicine — you don’t have to wait until it’s unbearable.
