Pregnancy does not always start with bright anticipation. For some moms, it starts with a fight for survival. The severe illness of pregnancy, called hyperemesis gravidarum (HG), can mean months of relentless nausea, repeated hospital stays and exhaustion that touches every part of life.
Now, new research published in The Lancet Obstetrics, Gynecology and Women’s Health reveals what many moms have felt: HG wreaks havoc on both the body *and* the mind, leaving lasting emotional scars. Women with HG face a significantly higher risk of depression, PTSD, and other mental health conditions. For countless moms, this is validation that’s long overdue.
What the study found
The researchers analyzed the health records of nearly half a million women in 18 countries. Their findings are striking:
- HG is associated with a 50% increase in mental health and neuropsychiatric disorders within the first year after diagnosis.
- Prices of postpartum depression nearly tripled in women with HG.
- Women also faced higher risks of PTSD, eating disorders, and even rare conditions like postpartum psychosis.
- Serious complications such as Wernicke’s encephalopathy, a neurological disorder caused by vitamin B1 deficiency, were also more common.
These findings make one thing clear: even when symptoms seem “milder,” HG can cause ongoing emotional and psychological struggles.

Why it matters to moms
For too long, women with HG have been told to “just toughen up”. Many have heard dismissive comments that their symptoms are exaggerated or “just morning sickness.” We’ve heard comments like “have you tried eating salty?” But this is no ordinary pregnancy sickness, it is a nightmarish experience where women can barely support themselves and too often their pain is overlooked, even by the medical community. This study proves that moms need a lot more support—HG is a serious condition that requires compassion, not minimization.
The toll is twofold: mothers struggle with relentless nausea, dehydration or hospitalization, while also being at increased risk of depression and other psychiatric disorders. Pregnancy, instead of being joyful, can feel overwhelming and scary. And they struggle physically and mentally to defend themselves through it all.
The data makes one thing clear: moms deserve real care and emotional support, not dismissal.

What experts want moms to know
Dr. Hamilton Morrinsaid a PhD at King’s College London Industrial that while mild nausea and vomiting are often normalized as part of pregnancy, hyperemesis gravidarum represents a serious spectrum with debilitating consequences.
Dr. Thomas PollakClinical Reader and consultant neuropsychiatrist at King’s College London, added that this study effectively bridges the gap between the lived experiences of women with HG and the medical community’s understanding.
Together, their voices highlight what moms have long known: HG care must heal both the body and the mind.
Practical foods for moms and their support networks
So what can moms—and the people who love them—do with this knowledge? Here are some steps that can make HG’s toughest days a little easier.
If you are a mom with HG:
- Talk to your provider openly about this both physical and emotional symptoms.
- Ask a partner or friend to support you in the medical system if you are too unable to stand up for yourself.
- Read the latest expert medical information from HER Foundation (a HG advocacy organization) and don’t take advice from uninformed family members on Facebook groups – too many people mistakenly believe that medication to treat nausea in pregnancy is potentially harmful to the baby. Is not. Trust the experts.
- Ask about mental health screening or a referral if you notice signs of depression, anxiety or PTSD.
- Monitor your symptoms – early intervention can protect both physical and mental health.
If you love someone with HG:
- Believe her and take her symptoms seriously.
- Offer specific help—meals, childcare, chores—so she doesn’t feel alone.
- Postpartum screening: the risks do not disappear after delivery.

The bigger picture
HG is both a medical crisis and an emotional journey that transforms how moms experience pregnancy. This study shows why healthcare providers, families and workplaces need to integrate mental health screening and compassionate support into care from day one.
For moms, this research offers hope. It confirms what many tearfully whispered: HG changes everything and deserves recognition.
