When even sips of water bring on vomiting, standard pregnancy nutrition advice does not apply. This article covers what to eat and drink when very little stays down, why hydration comes first, why survival eating is enough during the acute phase, and when to seek urgent medical support. **Q: What foods are most likely to stay down with hyperemesis gravidarum?** A: No single food works for everyone. Bland, starchy foods like plain crackers, dry toast, and plain potatoes often sit better, and cold or cool foods can be easier because they smell less. Eating very small amounts often tends to help more than going for full meals. Whatever you can keep down is the right food to eat. The nausea that does not pass, the retching before you have even sat up, the way the smell of almost any food makes things worse. When you have hyperemesis gravidarum, eating is not about choices in any normal sense. Hyperemesis gravidarum (HG) is a severe form of pregnancy sickness, more extreme than the morning sickness most people link with early pregnancy. It brings constant, intense nausea and vomiting that can stop you keeping down food or drink. The gap between what you know you are meant to eat and what you can actually manage can feel huge, and upsetting. This article does not close that gap with a meal plan. It focuses on what is actually doable when almost nothing stays down. HG affects around 1 to 3 in every 100 pregnant women. If you have it, you are dealing with a serious medical condition that deserves proper support. ## Hydration comes first When you are struggling to keep anything down, staying hydrated matters more than anything else right now. Sipping fluids slowly and often through the day tends to sit better than trying to drink a lot at once. Small, regular sips give your stomach less to react to. If plain water is hard to keep down, you might find it easier to suck on ice cubes or ice lollies, sip flat fizzy drinks or flavoured water, or eat foods with a high water content like melon. Flat fizzy drinks sit better than still water for some people, and do little for others. There is no single right answer here. Finding what you can keep down is the goal. > **WARNING**: If you cannot keep any food or drink down for 24 hours, or if you notice signs of dehydration such as dark-coloured urine, dizziness, or severe tiredness, get urgent medical help. Call NHS 111, call your midwife, or go to A&E. Do not wait. ## Hyperemesis gravidarum eating: survival is the goal When HG is at its worst, the aim shifts completely. What matters becomes keeping down whatever food or drink you can, so you get some calories and fluids in, rather than eating a balanced diet. This is sometimes called survival eating, and it is the right approach during the acute phase. The idea that you should be managing well-rounded, nutritious meals does not apply when you cannot keep a cracker down. As symptoms ease, even a little and only for a while, you can come back to nutritional balance. During the hardest stretches, anything that stays down is enough. ## What to try when almost nothing stays down Eating small amounts often can help. An empty stomach can make nausea worse, so even a few bites at a time counts. Bland, starchy foods tend to sit better than rich or strongly flavoured ones. Crackers, dry toast, and plain potatoes are often manageable, though what works shifts from person to person. No single food helps everyone with HG. Cold or cool foods may be easier to manage because they smell less, and smell can be one of the hardest parts of HG to cope with. If the thought of a hot meal is enough to bring on nausea, cold options are worth a try: cold pasta, plain crackers, chilled fruit, or anything from the fridge you can keep down. Whatever your body accepts, at whatever temperature, is the right thing to eat. You do not have to eat anything in particular. If the only things you can keep down today are plain crackers and ice lollies, that is what today looks like. ## When to seek medical support HG is a medical condition that needs medical care. The strategies here are there to support you through it, and they do not stand in for treatment. Call your GP, midwife, or hospital if you cannot keep any food or fluids down because of severe vomiting. Losing more than 5% of your pre-pregnancy body weight is a sign the condition has become severe and needs assessment by a healthcare professional. Severe HG sometimes means a hospital stay, where you can be given fluids through a drip to treat dehydration, along with anti-sickness medication through a drip or injection. Going into hospital for HG is a standard, effective step that helps you recover. > **INFO**: Always speak to your GP or midwife if you are worried about your symptoms, about what you can eat or drink, or about how you are doing in general during pregnancy. The food and hydration strategies in this article are there to support you and do not replace clinical care. ## The emotional weight of HG How relentless HG is can wear you down emotionally as much as physically. Feeling isolated, anxious, or misunderstood is common. If you are struggling in your mind as well as your body, it is worth raising with your GP or midwife. Talking to others who have lived through HG can ease that sense of isolation too. Pregnancy Sickness Support is a charity that offers peer support from people who have been through HG themselves. --- **Q: What foods are most likely to stay down with hyperemesis gravidarum?** No single food works for everyone. Bland, starchy foods like plain crackers, dry toast, and plain potatoes often sit better, and cold or cool foods can be easier because they smell less. Eating very small amounts often tends to help more than going for full meals. Whatever you can keep down is the right food to eat. **Q: How can you stay hydrated when even water triggers vomiting?** Sipping very small amounts through the day is more likely to stay down than drinking a lot at once. If plain water is hard, try sucking on ice cubes or ice lollies, sipping flat fizzy drinks or flavoured water, or eating foods with a high water content like melon. If you cannot keep any fluids down at all, call your GP, midwife, or NHS 111. **Q: When does hyperemesis gravidarum require urgent medical attention?** Get urgent medical help if you have not kept any food or drink down for 24 hours, or if you have signs of dehydration such as dark-coloured urine, dizziness, or severe tiredness. Losing more than 5% of your pre-pregnancy body weight is another sign you need professional assessment. Call NHS 111, call your midwife, or go to A&E. Severe HG may need hospital treatment with fluids through a drip and anti-sickness medication. **Q: Does a balanced diet matter during the worst phases of HG?** During the worst stretches, the goal is survival eating: keeping down whatever you can so you get some calories and fluids in, rather than eating a balanced diet. That is the right approach for the acute phase. As symptoms ease, you can slowly come back to nutritional balance. Talk to your midwife or GP about how to handle nutrition as things change. ### Clinical Sources - [Coping Strategies](https://pregnancysicknesssupport.org.uk/get-help/coping-strategies/) - [Vomiting and morning sickness](https://www.nhs.uk/pregnancy/common-symptoms/vomiting-and-morning-sickness/) - [Vomiting and morning sickness](https://www.nhs.uk/pregnancy/common-symptoms/vomiting-and-morning-sickness/) - [The Management of Nausea and Vomiting in Pregnancy and Hyperemesis Gravidarum (Green-top Guideline No. 69)](https://obgyn.onlinelibrary.wiley.com/doi/10.1111/1471-0528.17739) - [Severe vomiting in pregnancy](https://www.nhs.uk/pregnancy/complications/severe-vomiting/) - [Severe vomiting in pregnancy](https://www.nhs.uk/pregnancy/complications/severe-vomiting/) - [Coping Strategies](https://pregnancysicknesssupport.org.uk/get-help/coping-strategies/) - [Severe vomiting in pregnancy](https://www.nhs.uk/pregnancy/complications/severe-vomiting/) - [Hyperemesis Gravidarum — UHCW NHS](https://www.uhcw.nhs.uk/download/clientfiles/files/Patient%20Information%20Leaflets/Clinical%20Support%20Services/Dietetics/Hyperemesis%20Gravidarum.pdf) - [Severe vomiting in pregnancy](https://www.nhs.uk/pregnancy/complications/severe-vomiting/) - [Coping Strategies](https://pregnancysicknesssupport.org.uk/get-help/coping-strategies/) --- Reviewed by Dr Rebeccah Tomlinson, Private GP Women's Health: Menopause Speciality | [Medical Board](https://blog.bloume.com/pregnancy/medical-board.md) | June 2026
