Morning Sickness: Why It Happens and What Helps
Despite the name, morning sickness can strike at any time of day. It affects a majority of pregnancies, usually in the first trimester, and while it's unpleasant, it's typically a normal part of early pregnancy.
Why It Happens
The exact cause isn't fully understood, but rising levels of the pregnancy hormone hCG and increased estrogen are thought to play a role. Nausea often begins around week 6 and, for most people, eases by weeks 12–16.
What Actually Helps
- Eat small, frequent meals. An empty stomach makes nausea worse. Keep something bland (crackers) by the bed and eat before getting up.
- Ginger in tea, chews, or capsules has evidence for reducing nausea.
- Stay hydrated with small, frequent sips. Cold or fizzy drinks are sometimes easier to tolerate.
- Avoid triggers — strong smells, greasy or spicy foods. Cold foods have less odor than hot ones.
- Vitamin B6 is sometimes recommended by providers; ask before taking supplements.
- Rest. Tiredness tends to intensify nausea.
When to Call Your Provider
Contact your healthcare provider if you can't keep fluids down for 24 hours, are losing weight, feel dizzy, or your vomiting is severe and constant. This can be a condition called hyperemesis gravidarum, which needs medical treatment.
