Nausea in the second trimester

By trimester

Weeks 14–27

2nd trimester

For most people, nausea gradually fades by now. When it doesn't, common causes to check include reflux, gallbladder discomfort, and less often, thyroid or infection-related issues. Check in with your provider if nausea is new or getting worse in the second trimester.

What does the evidence show for nausea in the second trimester?

• Nausea and vomiting typically resolve by about 14 weeks for most people, though some continue to have symptoms into and through the second trimester. 1
• If an anti-nausea medicine like doxylamine plus B6 is working, it's fine to keep using it as long as symptoms need it, rather than stopping at some fixed week. 2
• If nausea first starts at 10 weeks or later, rather than easing off by then, it might have a different cause and is worth discussing with your healthcare provider. 3
• The FDA-approved combination of doxylamine and B6 (Diclegis) is approved for pregnancy nausea and can be continued past the first trimester when your provider directs it. 4

When should I call my provider about nausea in the second trimester?

By the second trimester most nausea is on its way out, so the pattern worth attention here is nausea that arrives new rather than nausea that lingers. MotherToBaby notes that symptoms first starting at the 10th week or later may be due to other causes, which makes brand-new second-trimester queasiness a reason to be checked rather than ridden out. Move the call earlier if nausea is blocking food, fluids, sleep, or a normal day. Relentless vomiting with weight loss and dehydration is the hyperemesis gravidarum picture, and hospitalization is part of that story. Trust your read on your own body. If something feels off beyond the list above, please consult your healthcare provider rather than waiting it out.
