Hi  another member asked about pregnancy related nausea recently so you can read about that thread and our detailed replies here. I’ll also summarize a few key points below: 
• Estrogen rises quickly during the first trimester of the pregnancy which can lead to nausea.  This meta analysis from 2014 concluded that the use of ginger (∼1 g daily) for at least 4 days is associated with a 5-fold likelihood of improvement in nausea and vomiting in early pregnancy. 

-> Do you know how much ginger she was taking? Maybe it’s not a high enough dose?
• The increase in hormones does also put more strain on the liver to detoxify the spent hormones, thus removing anything that can strain the liver can help (cleaning up personal hygiene products, eating more organic if possible, eliminating anything that requires liver detox like caffeine, artificial sweeteners, etc), as well as balancing blood sugar levels (how’s her diet?). Sleep quality is important too since good liver and hormone function rely on quality sleep.

In addition to ginger tea/supplements, here are some foods that support liver/gallbladder health:

• Beet kvass (recipe in in handouts in Resources section)
• Beets cooked any way served with a little coconut oil, butter or extra virgin olive oil
• A squeeze of lemon in water
• Turmeric in dishes
• Garlic, lightly cooked
• Extra virgin olive oil
• Broccoli, cauliflower, Brussels sprouts, etc
• Greens (dandelion, turnip, beet, arugula)

Other issues may be associated with nausea:
• Estrogen and progesterone imbalances
• Thyroid levels
• Serotonin and leptin levels
• Immune system dysregulation
• H pylori infection and pregnancy induced changes to the upper GI
• High histamine levels (if this is the reason, trying a DAO enzyme supplement like Seeking Health’s Histamine Block may help)

Also, many prenatal vitamins could be the cause of nausea in pregnancy. Do you know what brand she’s using? If it contains iron, this could be causing nausea too.

Some people are also sensitive to methylated forms of B vitamins so choosing one that is methyl-free can often help reduce nausea. I like Seeking Health’s Optimal Prenatal Methyl Free

Stopping her prenatal for a few days could help her see if it’s contributing to her symptoms, and then maybe shop around for another form that is methyl-free, and perhaps a different form of iron.

More tips were shared in the member’s post I linked above. 

Hope this helps her! And please ask her to join us here in B Better. We’d be happy to support her too.

I’d love to see those studies about ginger if you can ask her to share them please.

And those supplements are methylated. As I said in my previous message, some women can’t tolerate those forms.

She can stop for a few days to see if they relieve her symptoms and then look at methyl-free options if it does.
