So many health-related rumors about pregnancy seem to indicate whether or not they have a foundation in actual medicine. A big one you might have heard: Morning illness means something good about the health of your pregnancy, even though it currently feels abominable.
It's a nice thing to think about when your head feels permanently stuck to the bathroom, but is that really real? We talked to ob / gyns and dug in the search for the truth.
Good sign or not, one thing is clear: the morning sickness can be a really tasty experience.
Morning sickness or nausea and vomiting during pregnancy It is estimated that up to 80 percent of pregnant people are affected, usually starting nine weeks before pregnancy, according to the American College of Obstetricians and Gynecologist (ACOG).
"How do you have a lot of morning sickness and how severe it actually is [vary]," says Christine Greves, MD, a graduate gynecologist at Winnie Palmer Hospital for Women and Babies, told SELF. For some, the morning sickness lasts several weeks or months, ACOG . For a few unfortunates it will take the entire pregnancy. And although the nickname "morning sickness" is catchy, it's not always accurate because you can experience nausea and vomiting related to pregnancy at any time.
It's hard to say exactly what causes morning sickness, but doctors think it generally depends on hormonal shifts. "The most widely accepted theory refers to an increase in two hormones during pregnancy: human chorionic gonadotropin (hCG) and estrogen," says Megan Quimper, a medical doctor at Ohio State University's Wexner Medical Center, opposite to SELF.
HCG has excreted from the placenta the organ that creates your body during pregnancy to feed the fetus via the umbilical cord. This hormone reaches its peak in early pregnancy, when morning sickness is usually the worst, Dr. Quimper. The placenta also produces estrogen which increases during pregnancy and contributes to morning sickness. Greves.
Besides these factors, it is possible that an increase in progesterone occurs. another hormone that supports pregnancy may slow the digestive process and possibly increase morning sickness .
Some pregnant women – up to 3 percent – experience the most severe form of morning sickness, named hyperemesis gravidarum .
A doctor may diagnose you with Hyperemesis gravidarum if you have lost at least 5 percent of your pre-pregnancy weight due to morning sickness and have symptoms due to severe dehydration. ACOG says.
Just like the morning sickness, doctors are not sure why hyperemesis gravidarum occurs in some people, but experts are investigating the theory that there is a genetic compound  38]. ACOG also says that one is pregnant with multiples, had a history of hyperemesis gravidarum, had a history of motion sickness or migraine and was pregnant with a fetus who was considered female at birth may also increase your risk.
While some evidence suggests that morning sickness is associated with a reduced risk of pregnancy complications, there is insufficient evidence to say that it means "much."
Basically, the morning sickness typically indicates that there is a shift in hormones to maintain a pregnancy, Dr. Iffath Hoskins, clinical professor in the Department of Obstetrics and Gynecology at NYU Langone Health. (There are some exceptions, such as when you have underlying conditions, such as thyroid or liver disease, that can cause nausea and vomiting during pregnancy, the Mayo Clinic says.)
In the morning, hormonal shifts can be signaled Illness provide a kind of defensive effect against pregnancy complications such as miscarriage and premature birth. However, research to support these claims is multifaceted and not exhaustive, so scientists are not yet sure if this effect is real or not.
A study from the year of JAMA Internal Medicine analyzed data from 797 pregnant women in the United States who had previously experienced one or two abortions. The authors of the study found that morning sickness in early pregnancy appeared to have a "protective link" that resulted in a 50 to 75 percent reduced risk of miscarriage. Experts are not sure why this possible protective effect exists, but one theory is that nausea and vomiting mean that a viable placenta with adequate hormones supports the fetus.
A 2018 study from BMC Pregnancy & Childbirth analyzed data from 96,056 pregnant women in Japan and found that those who had no morning sickness had a slightly higher premature birth rate while those with severe morning sickness had the lowest risk. People with morning sickness also experienced fewer cases of pregnancy-related hypertension . Interestingly, however, individuals with morning sickness experienced higher rates of "threatened abortions" ( vaginal bleeding with or without abdominal cramps in the first trimester ) and "threatened premature labor" ( suffered contractions 37 weeks ).
There is a similarly interesting variation in a 2015 study by BMC Pregnancy & Childbirth in which 51,675 pregnant women in Norway were examined for nausea and vomiting during pregnancy a higher probability of Complications such as hypertension and pre-eclampsia as their symptom-free counterparts, but a lower likelihood of problems such as premature birth and low birth weight.
Obviously, there are some fascinating possibilities of relationships between morning sickness and maternal and fetal health, but science has not determined anything definite yet. It is difficult to prove cause and effect for any of these claims. The fact that so many people experience morning sickness makes it difficult to study. Greves. Think of all the variables researchers need to exclude in order to truly study only the effects of morning sickness on pregnancy and childbirth without considering other factors. Several studies also point to a contradictory classification of nausea and vomiting during pregnancy as a complicating problem.
Ultimately, there is no medical reason that morning sickness is automatically classified as "good" or "bad." It's just one thing that happens to many people during pregnancy.
There is no scientific reason to believe that a lack of morning sickness is worrying.
"If you have no morning sickness, that does not mean Pregnancy is unhealthy," Dr. Quimper. Experts do not know why some people have morning sickness and others do not, but going through pregnancy without nausea and vomiting does not automatically mean that something is wrong.
The only thing that can really be "wrong" when it comes to it Morning sickness is when you suffer from hyperemesis gravidarum because it means that nausea and vomiting are too strong. If you think you have hyperemesis gravidarum, you must discuss with your doctor that you pay particular attention to your health, nutrition and hydration. First, it can help to make you less miserable. In addition, unrelenting nausea and vomiting can make it difficult to get enough calories, which in the worst cases can theoretically negatively affect fetal growth Hoskins.
With this reference here's the link ] is also not definitive, as this review of 81 related studies 2017 Pharmacology explains, so you do not immediately fear that a hyperemesis gravidarum your Could affect baby. "This disease alone does not usually affect your baby's health, because pregnancies are very resilient," says Dr. Quimper. But talk to your doctor anyway. If you have hyperemesis gravidarum, you may benefit from IV treatment and anti-nausea medications .
The Snack: It is quite possible and common to have a healthy baby, even if you have the heaviest version of morning sickness. It is also completely possible – and again common – to get a healthy baby if you have no morning sickness at all. However, if you are worried about your morning sickness or anything else about your pregnancy, it is always a good idea to consult your doctor.
