Dealing with morning sickness


Vomiting and morning sickness - NHS

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

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

Morning sickness is a feeling of nausea or the experience of vomiting during pregnancy, most commonly during the first trimester. Despite its name, morning sickness can happen at any time of the day or night. While most pregnant women experience morning sickness at some point, for many women, it will pass by the second trimester.

Why do pregnant women get morning sickness?

Although the exact cause of morning sickness is unknown, it is associated with hormonal changes that occur during pregnancy.

An imbalance of dietary potassium and magnesium, low blood sugar and low levels of vitamin B6 (pyridoxine) are all known causes of nausea. Following a diet that includes whole foods with a wide range of vitamins and minerals will help you stay healthy and well during your pregnancy.

Having a healthy pregnancy

Having a healthy pregnancy means following a healthy diet, getting regular exercise, knowing what to avoid and making sure your vaccinations are up to date.

Why does it affect some women more than others?

Some women are more likely to feel nauseous during pregnancy than others. While morning sickness is hard to predict, women who have experienced morning sickness in a previous pregnancy are more likely to have it again.

How long does morning sickness last?

You are more likely to feel morning sickness between 6 and 14 weeks of pregnancy, during your first trimester. While it is commonly known as ‘morning’ sickness, it may last throughout the day or night.

It is unusual to experience morning sickness for the first time after week 10 of pregnancy, so if this happens to you, consult your doctor to rule out other health conditions and to give you peace of mind.

How can I relieve morning sickness?

To relieve morning sickness, consider:

  • eating smaller meals more often (include morning and afternoon snacks between main meals)
  • eating a plain cracker shortly after waking up
  • drinking water before and after a meal, rather than with food
  • aiming to drink 8 glasses of water a day
  • avoiding spicy or fatty foods
  • eating protein-rich foods (such as nuts or cheese)
  • avoiding skipping meals

Soda (or carbonated) water and ginger/peppermint tea are also known to help relieve nausea and settle an upset stomach.

Some women become more sensitive to strong food smells while pregnant. If certain smells bother you, consider asking for help preparing your food. You can also increase ventilation in your kitchen while cooking by opening windows to get rid of cooking smells. Cold foods produce less odour than hot foods, so you may find these more appetising.

Nausea may feel worse when you are over-tired, and taking rest or nap breaks frequently throughout the day may help. Other suggestions include:

  • deep breathing or relaxation exercises
  • anti-nausea wristbands (available at most chemists)
  • acupuncture treatments(but only when administered by a qualified practitioner trained in maternal care)

Be sure to check with your doctor before you take any supplement, prescription or over-the-counter medicine, especially while pregnant.

Is morning sickness harmful for my baby?

Even though morning sickness can be unpleasant and distressing, there is no research to suggest that it causes harm to your baby. Nausea may, however, influence your food choices. Both you and your baby need an ongoing source of a range of nutrients in the foods you eat. Speak with a health professional if you think that your morning sickness is getting in the way of healthy eating.

It is also important to prevent dehydration, so if you are vomiting and unable to keep fluids down, see your doctor immediately.

What do I do if my morning sickness is severe?

When morning sickness is severe, it is known as hyperemesis gravidarum. A pregnant woman who experiences severe vomiting for an extended period of time may need monitoring and treatment in hospital. An intravenous (IV) drip is inserted to replace essential salts and fluids and prevent dehydration. If you are vomiting whenever you eat or drink, consult a health care professional, since early treatment can protect you and your baby from health complications.

When should I see my doctor about morning sickness?

If nausea or vomiting is causing significant discomfort, or if you suspect that you have hyperemesis gravidarum, you should see your doctor.

Other signs you need to see a doctor include:

  • very dark urine
  • blood in vomit
  • extreme fatigue
  • dramatic weight loss
  • dehydration due to inability to keep fluids down

CHECK YOUR SYMPTOMS — If you are feeling unwell and not sure what to do next, check your symptoms using the healthdirect Symptom Checker tool.

In some cases, a doctor may advise a home remedy. In other cases, they may refer you to another healthcare professional, such as a dietitian — to help you create a healthy and enjoyable meal plan — or to a specialist for further tests. Your doctor may prescribe you with medicine to ease your symptoms, such as an antiemetic (to prevent vomiting), or vitamin and mineral supplements.

If your symptoms persist after treatment, it is a good idea to return to your doctor for another consultation — there may be another approach you can try.
