Nausea and Vomiting in Pregnancy What’s Actually Happening and How to Find Relief

Understanding morning sickness through both a clinical and Chinese Medicine lens

By Joanna McKeown

You’re growing a human being, and your body is letting you know.

For many women, nausea is the first real sign that something extraordinary is happening. It often arrives before the bump shows, before the world knows, and sometimes before you have fully taken it in yourself. And honestly? It can feel deeply unglamorous.

Morning sickness is incredibly common, genuinely exhausting, and something many women silently struggle through while still trying to work, parent, function, and navigate everyday life.

The good news is there are evidence-based ways to support nausea and vomiting in pregnancy — and understanding why it happens can help you feel less overwhelmed by it all.

What Is Morning Sickness?

Despite the name, “morning sickness” is not just a morning thing.

Nausea and vomiting in pregnancy (NVP) affects up to 80% of pregnant women, and symptoms can occur at any time of the day or night.

For many women:

• Symptoms begin around 6 weeks pregnant

• Peak around 9–10 weeks

• Improve by 13–16 weeks

  
  

Some women experience symptoms for longer, and for a small percentage, nausea becomes severe enough to develop into Hyperemesis Gravidarum (HG).

Why Does Pregnancy Cause Nausea?

The Western Medicine Perspective

From a medical perspective, nausea in pregnancy is largely driven by rapidly rising hormones.

Human chorionic gonadotropin (hCG), produced by the developing placenta, appears to play a major role. Interestingly, hCG levels peak at around the same time morning sickness is often at its worst.

Other contributing factors include:

• Rising oestrogen and progesterone

• Slower digestion

• Heightened smell sensitivity

• Low blood sugar

• Fatigue

• Stress and anxiety

  
  

Emerging research also points to the hormone GDF15 as a likely contributor to more severe pregnancy nausea and Hyperemesis Gravidarum.

Women carrying multiples, those with a history of motion sickness or HG, and women with thyroid or digestive conditions may experience stronger symptoms.

A Chinese Medicine Perspective on Pregnancy Nausea

In Traditional Chinese Medicine (TCM), nausea in pregnancy is often described as “rebellious Stomach Qi.”

Normally, digestive energy moves downward to support digestion. During early pregnancy, that energy can move upward instead — leading to nausea and vomiting.

Chinese Medicine also recognises a deep connection between the uterus and digestive system through the Chong Mai, or Penetrating Vessel.

During early pregnancy:

• Energy and blood are redirected inward

• Digestion can temporarily weaken

• Stress and exhaustion can worsen symptoms

• Emotional overwhelm may disrupt digestive balance

  
  

This perspective reframes nausea not as weakness or failure, but as part of the profound physiological changes occurring during pregnancy.

What Is Hyperemesis Gravidarum (HG)?

Hyperemesis Gravidarum is not simply “really bad morning sickness.”

It is a serious medical condition involving:

• Significant dehydration

• Weight loss

• Inability to tolerate food or fluids

• Electrolyte imbalances

• Persistent vomiting

  
  

HG often requires medical support including medications, IV fluids, or hospital care.

When Should You Seek Medical Help?

Please contact your GP, midwife, or maternity care provider if:

• You cannot keep fluids down for more than 24 hours

• You are barely urinating

• You feel faint or dizzy

• You are losing weight

• There is blood in your vomit

• You develop abdominal pain, fever, or neurological symptoms

  
  

These signs may indicate severe dehydration, HG, or another condition requiring urgent assessment.

What Actually Helps Morning Sickness?

Eat Small, Frequent Meals

An empty stomach is one of the biggest triggers for nausea.

Eating small amounts every 1–2 hours can help stabilise blood sugar levels and reduce symptoms. Even a few crackers before getting out of bed may help.

Focus on Warm, Gentle Foods

Many women tolerate:

• Soups and broths

• Plain toast or crackers

• Oats

• Rice or congee

• Eggs

• Mashed potato

• Stewed fruit

  
  

Warm, cooked foods are often easier to digest than cold or heavily processed foods during early pregnancy.

Sip Fluids Slowly

Large drinks can worsen nausea.

Instead, try:

• Small frequent sips

• Ginger tea

• Lemon water

• Coconut water

• Peppermint tea

• Electrolyte drinks

  
  

If vomiting has been ongoing, oral rehydration fluids may help support hydration.

Does Ginger Help Pregnancy Nausea?

Yes — and the evidence behind it is quite strong.

Research shows ginger can significantly reduce nausea symptoms and may work similarly to some anti-nausea medications for mild to moderate symptoms.

You can try:

• Fresh ginger

• Ginger tea

• Ginger capsules

• Crystallised ginger

  
  

Vitamin B6 for Morning Sickness

Vitamin B6 (pyridoxine) is commonly recommended as part of first-line treatment for nausea in pregnancy and has good evidence supporting its use.

Always speak with your healthcare provider before starting supplements.

Acupressure and Sea-Bands

The PC6 acupuncture point on the inner wrist is one of the most researched pressure points for nausea relief.

Sea-Bands and wrist acupressure bands may help reduce pregnancy nausea for some women and are considered safe to trial during pregnancy.

Managing Smell Sensitivity During Pregnancy

Many women find smell sensitivity one of the hardest parts of early pregnancy.

Some practical strategies include:

• Cooking with windows open

• Avoiding strong food smells

• Using lemon or peppermint scents

• Switching toothpaste flavours if brushing triggers gagging

• Eating cold foods if warm meals worsen nausea

Rest Is Part of the Treatment

Pregnancy fatigue and nausea are closely linked.

During the first trimester, your body is rapidly developing the placenta, shifting hormones, and supporting enormous physiological change.

Rest is not laziness.Rest is a biological need during pregnancy.

More sleep, slowing down, asking for help, and reducing pressure where possible can genuinely improve symptoms.

Morning Sickness and Mental Health

Nausea and vomiting in pregnancy do not just affect the body.

They can affect:

• Mental health

• Relationships

• Parenting

• Work

• Emotional wellbeing

• Daily functioning

  
  

Many women experience increased anxiety, emotional overwhelm, and isolation during prolonged nausea.

The first trimester is not only a physical transition. It is also the beginning of matrescence — the emotional and psychological transition into motherhood.

Support matters.

You Do Not Need to “Just Push Through”

Pregnancy nausea may be common, but that does not mean you need to minimise your experience.

There is a difference between:

• normal pregnancy nausea,

• severe dehydration,

• and suffering silently.

  
  

Whether support comes from your GP, midwife, counsellor, nutritionist, Chinese Medicine practitioner, or support network — you deserve care too.

Because growing a baby is hard work, even when nobody else can see it yet.

If you are struggling with nausea, vomiting, exhaustion, or simply feeling overwhelmed during pregnancy, you do not have to navigate it alone.
