Pregnant and When I Eat I Feel Sick

November 17, 2021

Nausea and vomiting in pregnancy, often known as morning sickness, is very common in early pregnancy.

It can affect you at any time of the day or night or you may feel sick all day long.

Morning sickness is unpleasant, and can significantly affect your day-to-day life. But it usually clears up by weeks 16 to 20 of your pregnancy and does not put your baby at any increased risk.

There is a chance of developing a severe form of pregnancy sickness called hyperemesis gravidarum. This can be serious, and there's a chance you may not get enough fluids in your body (dehydration) or not get enough nutrients from your diet (malnourishment). You may need specialist treatment, sometimes in hospital.

Sometimes urinary tract infections (UTIs) can also cause nausea and vomiting. A UTI usually affects the bladder, but can spread to the kidneys.

Non-urgent advice: Call your midwife, GP or 111 if:

you're vomiting and:

have very dark-coloured urine or have not had a pee in more than 8 hours
are unable to keep food or fluids down for 24 hours
feel severely weak, dizzy or faint when standing up
have tummy (abdominal) pain
have a high temperature
vomit blood
have lost weight

Important: Coronavirus (COVID-19) update

If you're well, it's really important you go to all your appointments and scans for the health of you and your baby.

If you're pregnant, hospitals and clinics are making sure it's safe for you to go to appointments.

If you get symptoms of COVID-19, or you're unwell with something other than COVID-19, speak to your midwife or maternity team. They will advise you what to do.

Treatments for morning sickness

Unfortunately, there's no hard and fast treatment that will work for everyone's morning sickness. Every pregnancy will be different.

But there are some changes you can make to your diet and daily life to try to ease the symptoms.

If these do not work for you or you're having more severe symptoms, your doctor or midwife might recommend medicine.

Things you can try yourself

If your morning sickness is not too bad, your GP or midwife will initially recommend you try some lifestyle changes:

get plenty of rest (tiredness can make nausea worse)
avoid foods or smells that make you feel sick
eat something like dry toast or a plain biscuit before you get out of bed
eat small, frequent meals of plain foods that are high in carbohydrate and low in fat (such as bread, rice, crackers and pasta)
eat cold foods rather than hot ones if the smell of hot meals makes you feel sick
drink plenty of fluids, such as water (sipping them little and often may help prevent vomiting)
eat foods or drinks containing ginger – there's some evidence ginger may help reduce nausea and vomiting (check with your pharmacist before taking ginger supplements during pregnancy)
try acupressure – there's some evidence that putting pressure on your wrist, using a special band or bracelet on your forearm, may help relieve the symptoms

Anti-sickness medicine

If your nausea and vomiting is severe and does not improve after trying the above lifestyle changes, your GP may recommend a short-term course of an anti-sickness medicine, called an antiemetic, that's safe to use in pregnancy.

Often this will be a type of antihistamine, which are usually used to treat allergies but also work as medicines to stop sickness (antiemetic).

Antiemetics will usually be given as tablets for you to swallow.

But if you cannot keep these down, your doctor may suggest an injection or a type of medicine that's inserted into your bottom (suppository).

See your GP if you'd like to talk about getting anti-sickness medication.

Risk factors for morning sickness

It's thought hormonal changes in the first 12 weeks of pregnancy are probably one of the causes of morning sickness.

But you may be more at risk of it if:

you're having twins or more
you had severe sickness and vomiting in a previous pregnancy
you tend to get motion sickness (for example, car sick)
you have a history of migraine headaches
morning sickness runs in the family
you used to feel sick when taking contraceptives containing oestrogen
it's your first pregnancy
you're obese (your BMI is 30 or more)
you're experiencing stress
