No one knows for sure but is thought to have something to do with hormones and other changes in the body-possible causes thought to include:

  • Human chorionic gonadotropin (hCG). This hormone rises rapidly during early pregnancy. No one knows how hCG contributes to nausea, but it's a prime suspect because the timing is right: Nausea tends to peak around the same time as levels of hCG. What's more, conditions in which women have higher levels of hCG, such as carrying multiples, are associated with higher rates of nausea and vomiting.
  • Estrogen. This hormone, which also rises rapidly in early pregnancy, is another suspect. (It's possible that other hormones play a role as well.)
  • An enhanced sense of smell and sensitivity to odors. It's not uncommon for a newly pregnant woman to feel overwhelmed by the smell of a bologna sandwich from four cubicles away, for example. Certain aromas instantly trigger the gag reflex. (Some researchers think this may be a result of higher levels of estrogen, but no one knows for sure.)
  • A sensitive stomach. Some women's gastrointestinal tracts are simply more sensitive to the changes of early pregnancy. Also, some research suggests that women with a stomach bacterium called Helicobacter pylori are more likely to have nausea and vomiting. Not all studies confirm this link, though.
  • Stress. Some researchers have proposed that certain women are psychologically predisposed to having nausea and vomiting during pregnancy as an abnormal response to stress. However, there's no conclusive evidence to support this theory. (Of course, if you're constantly nauseated or vomiting a lot, you certainly may begin to feel more stressed!)

Can you have morning sickness only for one day?

In early pregnancy it is possible, but it would not be a real common thing. But every woman is different, as are her pregnancies. It might be a one day thing if your body has just detected you are pregnant and are producing high or fluctuating levels of HCG (human chorionic gonadotopin), which is a pregnancy hormone that is believed to be one of the main causes of morning sickness. Sometimes morning sickness will come only once or twice, then nothing for a few weeks, but then it really kicks in. Like the calm before the storm, so to speak. With my first pregnancy I had exactly two little waves of nausea a few days apart during the third or fourth week. That was it! Why not just take a home pregnancy test and get it over with so you will know whether to watch for more symptoms or not? Some people experience no morning sickness ever. if you really feel that you are having morning sickness, then just take a test and find out for sure if you are pregnant and that could be what is causing your symptoms. Take a test. Not everyone gets morning sickness.


Could feeling sick but not having the morning sickness vomiting be a sign of being pregnant?

Absolutely! You can just be queasy or not feel any thing at all. If you are pregnant, the farther along you get, the more stable the increased levels of hormones get. One of the causes of morning sickness is the higher levels of hormones in your body. That is why pregnancy tests work better when not taken too early. Each pregnancy can also be very different.

Do most women have morning sickness?

No, not every woman will experience morning sickness during pregnancy. About 75% of pregnant women have morning sickness at sometime during their pregnancy. The good thing is, obviously, you won't be sick. The bad thing is that it may be harder for you to notice your symptoms of pregnancy if you are not planning it.Here is advice and input:I'm pregnant and besides getting violently ill once for a few minutes, I have not been sick. My first doctor's visit will be next week. And, I hope eveything' is fine.Some people don't get morning sickness at all. I know people who don't. Those people are extremely lucky.Not everyone has specific pregnancy symptoms. Morning sickness is a common one that many women experience.No. It is a very common condition for women who are pregnant, but some don't even experience "morning sickness". Some women have it early in the pregnancy, for others it is late or in the middle, and in a few women it lasts the entire 9 months. I, however, am one of the lucky ones, I am 14 weeks pregnant with no morning sickness at all.At least one fourth of all pregnancies do not involve morning sickness. Approximately 50 to 75 % of pregnant women experience a period in early pregnancy with nausea, and about 30% also experience vomiting.Some studies have shown that you are more likely to have morning sickness if:You have a history of migraines.You had nausea and vomiting in a prior pregnancy.You have a medical history of negative side effects of nausea and vomiting from trying birth control pills. Some women have this response to higher estrogen levels.You tend to have motion sickness.If your mother or sisters have had morning sickness, there are studies to suggest that there is higher chance you will, due to a genetic predisposition.One study found that you are 50% more likely to have morning sickness with severe nausea and vomiting if your baby is a girl.You have twins or other multiples. There are higher levels of pregnancy hormones in your system when carrying twins, which also can make it so the symptoms are worse than average in some women. But it is not universal, some mothers of twins have no nausea or vomiting at all.Everyone is different. Some people don't experience sickness at all. Some people do all day, everyday. Some people only every once in a while. In fact some people have no symptoms at all.Of course every woman is different, some may experience no morning sickness at all, whereas others will experience it all the way through their pregnancy.


Is it possible to experience morning sickness but be too early for home pregnancy test to detect pregnancy?

It is my understanding that it is not so much the hcg that causes the nausea of morning sickness, but the vast amounts of progesterone being put out by the fertilized egg. I have four children and I am currently pregnant again. I have been nauseated off and on for the last four days. I literally JUST missed my period, so yes...you can get nausea before the test will give you a positive. At least in my case.


How To Understand Morning Sickness?

Most pregnant women will suffer through a bout of morning sickness. Some women will not get it as often while others can have it through many months of their pregnancy. It is the most common to get it during the early part of pregnancy.A lot of women find out that they are pregnant by starting to have morning sickness. It has been known to start as early as the fourth week of pregnancy, but more commonly starts during the sixth week. The worst sickness happens mainly in the next four to six weeks. The majority of the women will be finishing with morning sickness before the fourth month, however some will continue on longer. There are a few women who will suffer with this all the way through the pregnancy.Even though it’s called morning sickness because it mainly happens after waking up in the morning, it can still last the entire day. There are several theories on what causes morning sickness, but no one knows exactly what causes it. One of those reasons is the rapid rise of hormones, especially estrogen, in early pregnancy. However, this doesn’t explain why some women will continue to have morning sickness even longer. Another theory is that in early pregnancy the woman has a very strong sense of smell and food or fragrance smells can overwhelm her.Other interesting ideas that may explain morning sickness are women that get migraine headaches, suffer from motion sickness, have a mother or other family members who have had it and even some say it’s because they are carrying a girl.A morning sickness problem can easily keep the woman from eating properly. She should be taking a prenatal vitamin with low iron or no iron. Iron can only add to the nausea. The vitamin will replace the nutrients that are being lost by not eating right and vomiting. These vitamins are best taken with food or right before bedtime.Some women will eat smaller, but more frequent meals throughout the day. Snacking on something bland like crackers can also help settle the stomach. Sipping cold, carbonated drinks in between the meals will also help.If the morning sickness does become too severe, see the physician and find out if there are other options to try.
