For many women, one of the earliest signs of pregnancy is nausea. It may begin with feeling slightly queasy, suddenly going off certain foods, or noticing that smells feel stronger than usual. For others, it can feel much more intense from the beginning, leaving them exhausted and struggling to get through the day.
Despite the name, morning sickness can happen at any time of day and while it is incredibly common, affecting around 80% of pregnancies, that does not necessarily make it easy.
In my work supporting women through pregnancy, I often remind mothers that nausea in pregnancy exists on a wide spectrum. For some it is mild and manageable, and for others it can feel relentless and overwhelming.
Understanding what is considered common, what may need further support and how to care for yourself through it can make a real difference.
Why does morning sickness happen?
Morning sickness is thought to be linked to the hormonal changes that happen in early pregnancy, particularly rising levels of human chorionic gonadotropin (HCG) and oestrogen.
These rapid changes are happening at the same time as your body is adapting to pregnancy, increasing blood volume, supporting the placenta and responding to the huge shift taking place physically and emotionally.
For many women, nausea begins around six weeks of pregnancy and often improves in the early stages of the second trimester. However, every pregnancy is different, and there is no exact timeline that applies to everyone.
What Is Considered Normal?
Pregnancy nausea can look very different from person to person. Some women feel mildly sick but continue with daily life relatively normally, while others may struggle with food aversions, exhaustion or occasional vomiting throughout the day. It is also common for symptoms to fluctuate, with some days feeling manageable, while others can feel much harder.
Although unpleasant, mild to moderate nausea and occasional vomiting are usually considered a normal part of early pregnancy, particularly if you are still managing to stay hydrated and keep some food down.
It's important to know that struggling does not mean you are ‘not coping well’. Pregnancy sickness can be physically and emotionally draining, even when it falls within the range of what is considered common.
When it may be more than morning sickness
For some women, symptoms become much more severe and begin to affect hydration, nutrition and daily functioning, and this may be a condition called Hyperemesis Gravidarum, often shortened to HG.
HG is not simply ‘bad morning sickness.’ It is a serious pregnancy condition that can cause persistent vomiting, dehydration, significant weight loss and difficulty functioning day to day. Women with HG may struggle to keep down fluids, feel dizzy or faint, become extremely weak or find themselves unable to continue normal daily activities.
Importantly, we now understand far more about HG than we once did. For many years, severe pregnancy sickness was misunderstood and, sadly, often dismissed as psychological.
More recent research has identified biological and genetic links, including the role of a hormone called GDF15, helping to validate that HG is a genuine physical condition rather than something women are simply expected to tolerate or ‘push through’.
This growing understanding is incredibly important, not only in helping women feel heard and believed, but also because it may lead to more targeted treatments in the future. In some cases, medical treatment, anti-sickness medication, fluids or hospital support may be needed.
I will be talking more about Hyperemesis Gravidarum in my next article, including how to recognise the difference and access the right support, because many women minimise how severe their symptoms have become for far too long.
Gentle ways to cope with pregnancy nausea
While there is no single solution that works for everyone, there are small things that can sometimes help ease symptoms.
Eating little and often may feel easier than large meals, especially if an empty stomach makes nausea worse. Dry foods such as crackers or toast can help some women first thing in the morning before getting out of bed. Cold foods are often better tolerated than hot meals, particularly if smells feel triggering.
Sipping fluids regularly throughout the day, rather than drinking large amounts at once, may also feel more manageable.
Some women also find relief through ginger, acupressure bands or prescribed anti-sickness medication, and it is important to know you do not need to “just suffer through it” if symptoms are affecting your wellbeing.
Pregnancy sickness is often worse when you are exhausted, physically run down or trying to push through without slowing down. Your body is working incredibly hard during these early weeks, even if very little can be seen from the outside, so rest when you need to. Listening to your body is incredibly important.
The emotional impact of pregnancy sickness
One of the hardest parts of pregnancy sickness is that it can feel invisible to everyone else. Early pregnancy is often a time when women are still keeping things private, while quietly trying to manage nausea, exhaustion and emotional overwhelm behind the scenes.
For some it can affect work, relationships, mental wellbeing and the ability to enjoy pregnancy in the way they expected and if your symptoms feel severe, it can become incredibly isolating.
It can also create a huge amount of anxiety, particularly around whether constant sickness, difficulty eating or weight loss could be harming your baby. Many women can feel guilt and worry during this time, especially if pregnancy feels different to what they expected.
For reassurance, pregnancy sickness itself does not harm your baby. Your body is incredibly adaptive during pregnancy and babies will continue to take what they need, even during periods when you are eating less than usual.
What matters most is making sure you are supported, monitored appropriately and reaching out for help if symptoms are becoming severe.
You deserve support, reassurance and proper care, whether your symptoms are mild or more significant.
Midwife insight
In my work, I often reassure women that during periods of pregnancy sickness, the focus is not on eating perfectly, but simply getting through as best you can.
As your sickness begins to ease, there will be plenty of time to nourish yourself and your baby with a more balanced and varied diet. In those early weeks, small amounts, simpler foods and whatever feels manageable is often enough.
But if you are unable to keep fluids down for more than 24 hours, notice signs of dehydration, feel increasingly weak or dizzy, or have lost weight, it is important to reach out to your midwife or GP for advice and support.
