Symptoms of morning sickness Symptoms of morning sickness can include: Nausea Loss of appetite Vomiting Psychological effects, such as depression and anxiety. The myth of hysteria and morning sickness Unrelenting morning sickness can have a profound effect on your quality of life, preventing you from working, socialising and looking after your other children.
Possible causes of morning sickness The cause of morning sickness remains a mystery, but it is thought a combination of physical and metabolic factors play a significant role, including: High levels of hormones, including oestrogen Fluctuations in blood pressure, particularly lowered blood pressure Altered metabolism of carbohydrates The enormous physical and chemical changes that pregnancy triggers.
Morning sickness and your baby Some women are concerned that the action of vomiting may threaten their unborn baby. Most women will get sick for a short time each day, possibly even vomiting once or twice. There is also a severe form of morning sickness known as hyperemesis gravidarum. Only 2 percent of women with morning sickness experience this severe condition. Though no one knows what causes the condition, it's possible that women who are carrying more than one baby may be more likely to have severe nausea and vomiting than those carrying just one baby.
For this type of morning sickness, your healthcare provider may prescribe medication to treat the nausea and vomiting. According to experts, between 70 and 85 percent of pregnant women experience morning sickness in their first trimester , and most women find that their symptoms usually go away in the second trimester , sometime around 16 weeks.
Every pregnancy is unique, but for some moms-to-be morning sickness can last for up to several months. Around 5 percent of pregnant women may experience morning sickness symptoms throughout their entire pregnancy. Every pregnancy and every mom-to-be is different. Snacking throughout the day opting for salty snacks like crackers , and sipping ginger tea or ginger ale, or sucking on ginger candy or a ginger lollipop may help relieve nausea.
Many women describe it as feeling "blech" all the time. Many also have specific and significant food aversions. In more serious cases, nausea lasts for several hours and vomiting happens frequently. And in the worst cases, some women experience hyperemesis gravidarum HG , a severe form of morning sickness that can result in weight loss, dehydration, and other complications.
Women with HG throw up so often that they can't keep down enough food and fluid, and may need to be treated in the hospital with IV fluids, vitamins, and medication. If you aren't able to keep liquids down for more than 12 hours, or solid foods down for 24 hours, call your healthcare provider.
Because morning sickness is common in pregnancy, some providers may minimize it. And some expecting moms are reluctant to seek help, in part because they're worried about taking medications that could affect their baby. But there are safe ways to get relief from morning sickness , including changes to your diet and lifestyle, natural remedies, and medication prescribed by your provider.
And many experts say that getting early help for morning sickness is important to prevent it from getting more severe. So be sure to talk to your provider if you're suffering. It varies from woman to woman, but symptoms tend to be the worst at around 9 or 10 weeks , when levels of hCG are at their highest.
At 11 weeks, hCG levels start to fall, and by 15 weeks they've dropped about 50 percent from their peak. Scientists believe that morning sickness may be the body's way of protecting your baby in early pregnancy from toxins and potentially dangerous foods.
This theory makes sense because the first trimester — when most women have the strongest morning sickness — is the crucial period of development when all of your baby's organs and physical structures form. Most women get relief from morning sickness by the second trimester , between 14 and 20 weeks. But some women with morning sickness continue to have symptoms beyond that, and a few women will experience it throughout their entire pregnancy. And wash your clothes more often with a lightly-scented or unscented detergent to get rid of encrusted smells.
Raw chicken, for example, is a common culprit. These 1-inch-wide bands put pressure on an acupressure point in the inner wrist. Your practitioner may also recommend a battery-operated wristband that uses gentle electrical stimulation like Reliefband. Another option is PsiBands: two acupressure wristbands with adjustable knobs that you place on the inside of your wrists.
Destressing can help minimize queasiness. Try classic stress-reduction techniques, like meditation and visualization or prenatal yoga. And try to hit the sack for as many hours as you can clock every night. Rushing tends to aggravate nausea. So take it easy in the morning: Linger in bed for a few extra minutes and nibble on a bedside snack before taking a long, warm shower.
A leisurely morning may seem impossible if you have other kids. So try to wake up before they do, which gives you a few moments of quiet time. Or let your partner take the morning shift. A wide variety of complementary medical approaches can help minimize the symptoms of morning sickness, including acupuncture, acupressure, biofeedback and hypnosis.
But one alternative remedy you definitely should not use for morning sickness is marijuana or THC-containing products, which have not been shown to be safe during pregnancy. Regular brushing helps keep your mouth fresh and reduces queasiness in the future. It also decreases the risk of damage to teeth from vomiting.
Brush your teeth or rinse your mouth after each meal and after bouts of vomiting once your tummy has settled a bit. If your usual toothpaste contributes to nausea toothpaste is a common trigger , ask your dentist to recommend another option or a good rinse.
Or use plain water. You may want to try taking it right before bed. If your current pill makes you nauseous, try taking it with a meal. Or consider a coated, powder or chewable supplement.
If your symptoms are particularly rough, ask your practitioner about switching your prenatal vitamin for one with more B6 and less or no iron , which can be particularly tough on a sensitive tummy. Also ask whether you should take an additional vitamin B6 supplement or the antihistamine doxylamine found in Unisom SleepTabs , or supplement with magnesium or a magnesium spray. If your morning sickness is severe, you may want to talk to your doctor about taking a prescription drug that's been approved by the FDA to treat nausea and vomiting during pregnancy.
Both Diclegis or Bonjesta have been proven safe and effective. Your doctor may sometimes prescribe an anti-nausea medication like scopolamine, Phenergan or Reglan.
A pregnancy diet that's high in protein and complex carbohydrates is not only good for baby, it can also help keep nausea at bay. Think whole grain toast and peanut butter, or hard cheese and crackers. Steer clear of greasy and processed fast foods, which are hard to digest and can make morning sickness worse.
