How many weeks does morning sickness start
When does morning sickness start?
Nausea is a well-known symptom of pregnancy, affecting at least 70% of expecting mothers. Also called morning sickness, nausea usually begins at around six weeks, peaks between weeks 8-11, and typically fades near the end of the first trimester. However, some women experience nausea as both a second trimester and third trimester symptom.
The early weeks of pregnancy can be an exciting and confusing time. You’re beginning a journey that involves many physical and emotional changes,, and you don’t always know how you’ll feel from one day to the next. But we’re here to help you understand the changes you’re going through, and morning sickness can be one of the most noticeable.
Below, we cover what to expect and what you can do to find some relief from this common pregnancy symptom.
What is morning sickness and what are the symptoms?
Morning sickness is a feeling of nausea, sometimes also accompanied by vomiting. It can be one of the earliest signs of pregnancy for many women, appearing a couple weeks after a positive pregnancy test.
Despite being called morning sickness, nausea in pregnancy can happen at any time of day. Women often feel the most nauseous on an empty stomach, which is most apparent when you wake up after not eating all night, hence how it got its name.
Symptoms of morning sickness frequently occur on their own, but can also be triggered by certain foods, smells, heat, stress and other factors. The feeling can range from slight queasiness, like being a little carsick, to more intense nausea and vomiting.
Can you be pregnant and not have morning sickness?
Morning sickness is made out to be very common in movies and television, and it is. But it’s also possible to be pregnant without experiencing it. Three out of 10 pregnant women don’t experience morning sickness, so it’s not rare or concerning if that’s the case.
The same goes for aversions to certain foods or smells. Every pregnancy is unique, so not every pregnant woman will experience the same symptoms. If you think you could be pregnant but aren’t experiencing morning sickness or other symptoms, taking a pregnancy test is the only way to find out for sure.
What causes morning sickness?
While the exact cause isn't well understood, many doctors believe morning sickness happens because of hormones. The pregnancy hormone human chorionic gonadotropin (hCG) reaches its highest level around the same time morning sickness is most severe. And, increases in the hormones estrogen and progesterone can make it harder for your body to digest food, adding to stomach discomfort.
When does morning sickness start?
If you’re one of the many pregnant women who experience morning sickness, you may start feeling nauseous somewhere around the sixth week of your pregnancy, typically two weeks after your first missed period. Symptoms may appear gradually or seem to happen overnight.
Is it normal to be nauseous all day when pregnant?
Don’t be fooled by the name. Morning sickness doesn’t only happen in the morning, and it’s very normal for it to last all day. No two women experience it in the same way. Also, some women who had morning sickness in their first pregnancy may not have any nausea at all in their second, and vice-versa.
When does morning sickness end?
Morning nausea usually peaks between weeks 8-11, and typically fades by the end of the first trimester. However, some women can experience nausea in their second trimester, and some even notice nausea near the end of pregnancy.
If your morning sickness lasts beyond your first trimester, you may be more sensitive to the effects of hormonal changes during pregnancy. Or you may just have a more delicate stomach. But it’s a good idea to bring up your morning sickness with your doctor or midwife to learn about your options for relief.
Hyperemesis gravidarum (HG)
If you’re throwing up more than two to three times a day and aren’t able to keep anything down, you may have hyperemesis gravidarum (HG), a form of severe morning sickness. Some cases can be treated with pressure-point wristbands, like those worn to prevent motion sickness. In other cases, you might need medication, bed rest or intravenous (IV) fluids to help reduce or eliminate symptoms.
Many women tolerate morning sickness because they know that nausea in pregnancy is very common, however they may not realize that severe vomiting is not as normal and requires attention. That’s why it’s important to know the signs of HG. Talk to your care provider right away if you are vomiting so much that you:
- Become persistently dehydrated
- Can’t keep any foods or liquids down for 24 hours
- Feel weak, dizzy or faint and/or lightheaded
- Lose three or more pounds in a week
It’s important to know what’s normal and what’s not. If you have any concerns about your morning sickness, our experienced team of OB-GYNs and midwives can help you get personalized care that’s right for you.
Is morning sickness bad for the baby?
It’s natural to wonder about whether your nausea and loss of appetite could be harmful to your baby. But rest assured, if you’re still able to eat and stay hydrated, your baby will still get all their needed nutrients. In rare and severe cases of morning sickness, your doctor or midwife will work to ensure that you and baby are getting the necessary nutrition and hydration to stay healthy.
What can I do to find relief from pregnancy nausea?
You don’t have to tough it out and wait for the day your morning sickness subsides. There are plenty of simple, safe and effective strategies you can try to combat nausea.
Eat smaller meals throughout the day
Having an empty stomach for too long can make anyone feel sick. Eating small snacks throughout the day in between larger meals can keep you from feeling queasy. But remember, eating too much can make you feel just as nauseous. It’s all about finding a balance that will keep you feeling good.
Avoid trigger foods
Some food and drinks are difficult to digest and may make you feel sicker. Try to stay away from caffeine, acidic foods such as tomatoes, and greasy or spicy foods.
Iron supplements can also contribute to nausea and constipation, so talk to your doctor or midwife if you’re taking one.
Try the B.R.A.T. diet
If you can’t seem to find anything that agrees with you, try these foods that are bland and easy to digest: bananas, rice, applesauce and toast.
Stay hydrated
Drink a lot of fluids. In addition to water, sports hydration drinks, broth and juice can help replace nutrients that you may lose from vomiting.
Consume ginger
Eating and drinking foods with ginger can help calm the feelings of nausea. Easy options include ginger ale, ginger hard candy, ginger lollipops or ginger tea.
Take a vitamin B6 supplement
Though it may already be present in your prenatal vitamin, taking additional vitamin B6 has shown to be effective in reducing nausea during pregnancy. You can take up 25 to 50 mg of vitamin B6 per day, but it’s best to talk to your care provider before taking additional supplements.
Wear a wristband
As mentioned above, there are a variety of wristbands available over the counter that are designed to prevent motion sickness. They work by applying pressure to specific pressure points that can help ease nausea.
Experiment with different temperatures
You may have an easier time eating or drinking cold foods and beverages, or your stomach may feel calmer after a hot meal. Room temperature or warm food and drinks can sometimes cause nausea.
Keep a morning sickness record
What time of day does nausea strike? What are you doing when it does? By tracking your symptoms, you just might identify triggers that make you queasy – like certain foods or smells – so you can avoid them going forward.
Pack the essentials
If morning sickness does end up causing you to vomit, you can make it easier by carrying a few supplies with you. Feeling prepared by bringing a toothbrush and toothpaste, mouthwash, a backup shirt and even a plastic bag can give you peace of mind and make morning sickness feel more manageable.
Ask your doctor or midwife about finding relief from pregnancy nausea
These remedies may not work for everyone, and there are other solutions for more persistent symptoms. Talk to your care provider about anti-nausea medications that are safe to take while pregnant.
While morning sickness can be a challenging part of any pregnancy, it’s also a sign that your body is doing what it needs to support your growing baby. That said, you shouldn’t have to suffer through pregnancy nausea that interferes with your daily life and your ability to be present at work or with family.
Fortunately, there’s help available to make your pregnancy a bit smoother and more comfortable. If you’d like to explore your options for improving symptoms of pregnancy nausea, our women's health experts are here to help.
Morning sickness | March of Dimes
Morning sickness is when you have nausea and vomiting during pregnancy. Even though it’s called morning sickness, it can happen any time of day.
Morning sickness usually starts at about 6 weeks of pregnancy and goes away in the second trimester.
Lots of pregnant women have morning sickness.
It usually doesn’t cause harm to you or your baby.Hyperemesis gravidarum is severe nausea and vomiting that needs treatment (sometimes in a hospital) to help you get better.
If your morning sickness is severe or if it goes into your fourth month of pregnancy, tell your health care provider right away.
What is morning sickness?
Morning sickness (also called nausea and vomiting of pregnancy) is nausea (feeling sick to your stomach) and vomiting that happens in the first few months of pregnancy. Even though it's called morning sickness, it can last all day and happen any time of day.
At least 7 in 10 pregnant women have morning sickness in the first trimester (first 3 months) of pregnancy. It usually starts at about 6 weeks of pregnancy and is at its worst at about 9 weeks. Most women feel better in their second trimester, but some have morning sickness throughout pregnancy. If you have morning sickness, tell your health care provider.
Mild morning sickness doesn’t harm you or your baby. But if nausea and vomiting becomes severe (called hyperemesis gravidarum), it can cause serious problems during pregnancy. You may need to stay in the hospital for treatment.
What is hyperemesis gravidarum?
About 3 in 100 women may have hyperemesis gravidarum. This is extreme, excessive nausea and vomiting during pregnancy. It can cause you to lose weight and become dehydrated (not have enough water in your body). It can start early in pregnancy and last the entire pregnancy. If you have hyperemesis gravidarum, you need treatment to help keep you and your baby safe.
You may be at risk for hyperemesis gravidarum if you:
- Are pregnant for the first time.
- Are pregnant with a girl.
- Are pregnant with multiples (twins, triplets or more). Being pregnant with more than one baby may increase your risk for severe morning sickness because you may have a large placenta and increased pregnancy hormones. The placenta grows in your uterus (womb) and supplies your babies with food and oxygen through the umbilical cord.
- Had mild or severe morning sickness in a previous pregnancy, or your mother or sister had severe morning sickness during pregnancy. Take your family health history to help you find out about health conditions that run in your family.
- Have motion sickness or migraines. A migraine is a severe headache that may make you sensitive to bright lights and sound.
- Are overweight.
- Have trophoblastic disease, a condition that leads to abnormal cell growth in the uterus (womb).
Signs and symptoms of hyperemesis gravidarum include:
- Vomiting more than 3 to 4 times a day
- Vomiting that makes you dizzy or lightheaded
- Vomiting that makes you dehydrated. Signs and symptoms of dehydration include feeling thirsty, dry mouth, a fast heart beat or making little to no urine.
- Losing more than 10 pounds in pregnancy
If you have hyperemesis gravidarum, your provider may treat you with medicine to help relieve your nausea and vomiting. You may need treatment in a hospital with intravenous (also called IV) fluids. IV fluids go through a needle into your vein. They help you stay hydrated and can give you nutrients that you usually get from food. If you continue to lose weight, you may need a feeding tube to make sure you’re getting enough nutrients for you and your baby.
What causes morning sickness?
We don’t know for sure what causes morning sickness. It may be caused by low blood sugar or increased pregnancy hormones. Morning sickness may be worse if you’re stressed or overly tired, if you eat certain foods or if you’re traveling (if you often have motion sickness).
Can you prevent or relieve morning sickness?
Yes. Here’s what you can do to help you feel better and even prevent morning sickness:
- Take a prenatal vitamin before you get pregnant. Talk to your health care provider about which one to take. Sometimes vitamins can upset your stomach, so take it with a snack.
- Keep snacks by your bed. Eat a few crackers before you get up in the morning to help settle your stomach.
- Eat 5 or 6 small meals each day instead of 3 larger meals.
- Eat foods that are low in fat and easy to digest, like cereal, rice and bananas. Don’t eat spicy or fatty foods.
- Eat healthy snacks between meals. This can help keep your stomach from being empty and helps prevent nausea. Try snacks that are high in protein, like milk or yogurt.
- Drink plenty of fluids, especially water.
- Avoid smells that upset your stomach.
You may have heard about these ways to prevent or relieve morning sickness. Talk to your provider before trying any of these:
- Acupressure and acustimulation (also called electrical nerve stimulation) wristbands. These involve putting pressure on or stimulating certain points of the body (called pressure points) to help prevent nausea.
- Acupuncture. This is a kind of treatment in which thin needles are put into your skin. If you’re thinking about acupuncture to help with morning sickness, tell your provider and find an acupuncturist who is trained to work with pregnant women.
- Ginger. Ginger is an herb (plant) used in cooking and medicine. Ginger ale, tea or candies may help relieve morning sickness.
Even if it’s legal where you live for either personal or medical use, it’s not safe to use marijuana to treat morning sickness. No amount of marijuana has been proven safe to use during pregnancy. If you’re thinking of using marijuana to help with morning sickness, talk to your provider about other treatments that are safer for your baby.
Is there medical treatment for morning sickness?
Yes. If you can’t relieve morning sickness on your own or if you have severe nausea and vomiting of pregnancy, your provider may treat you with these medicines:
- Vitamin B6 and doxylamine. Your provider may treat you with these medicines separately or together. You can get vitamin B6 and doxylamine over-the-counter (OTC), which means you don’t need a prescription for them from your provider. Doxylamine is found in some OTC sleep aids (medicines that help you sleep). Or your provider may prescribe you a medicine that combines them.
- Antiemetic drugs. These are drugs that help prevent vomiting. If Vitamin B6 and doxylamine don’t work, your provider may prescribe an antiemetic drug for you. Not all are safe to use during pregnancy, so talk to your provider to make sure the medicine is a good choice for you.
Talk to your provider before you take any medicine during pregnancy, even medicine to help treat morning sickness.
When should you call your health care provider about morning sickness?
For most women, morning sickness is mild and goes away over time. But call your provider if:
- Your morning sickness continues into your 4th month of pregnancy.
- You lose more than 2 pounds.
- Your vomit is brown in color or has blood in it. If so, call your provider right away.
- You vomit more than 3 times a day and can’t keep food or fluids down.
- Your heart beats faster than usual.
- You’re tired or confused.
- You’re making much less urine than usual or no urine at all.

When early toxicosis begins and how to deal with it during pregnancy
Early toxicosis of pregnancy is a condition that causes a lot of suffering to a woman. Some feel "trick" even before the delay, while for others it all starts from 5-6 weeks. Obstetrician-gynecologist Galina Vladimirovna Ovsyannikova talks about the causes of toxicosis and ways to alleviate it.
Symptoms of toxicosis
Eating habits change drastically, hypersensitivity to odors, nausea, irritability appear, constantly wanting to sleep.
Rarely appear uncontrollable salivation, subfebrile temperature, vomiting.
Usually this condition takes a woman by surprise. After all, she needs to continue working, taking care of her family, she has a lot of things planned. With this, she goes to the doctor, already pretty tired and with a sad look. And we're starting to figure it out.
First of all not everyone suffers from toxicosis. Some simply eat everything and do not gain weight, or even lose weight, and this manifests their toxicosis. These women are lucky. Although they also manage to worry about this, as they have heard enough "as it should be" from their friends.
Secondly, the severity of toxicosis depends on the state of the nervous system, lifestyle and "similarity" of the baby to his mother in terms of protein composition.
And more about that.
Toxicosis: why and for what?
- Nervous system. It has been noticed that toxicosis is most pronounced in anxious women, leaders, doctors, teachers, that is, people with increased nervous stress. And, by the way, note that animals do not have such toxicosis as humans do. They do not take on "the entire world responsibility" and therefore they do not feel sick or vomit. At most, females sleep a lot and retire to save energy.
- Lifestyle. If a woman enters pregnancy not in a resource state, tired, exhausted, slagged from poor nutrition and lack of water, and even after some kind of illness, poisoning, herpetic manifestation, SARS, then the body will try to "put the woman to bed" in order to sleep, rest, gain strength, eat different foods to replenish supplies. Everything is logical. This is a smart move in the fight for survival.
- Any person has a unique genetic code, which is laid already at the moment of fertilization. And how different it will be from the mother's code, toxicosis will be so pronounced. To make it clearer, there are people who are so similar in this code, protein composition, that their organs can be transplanted to each other and they will take root. And others, on the contrary, are not at all similar, and if, for example, a kidney is transplanted from such a person, then it will be rejected. Also here. If a child has inherited a similar genetic code, then intoxication from getting his protein into the mother's blood will be less. And vice versa. As pregnancy progresses and the placenta forms between the body of the mother and child, a placental barrier is formed. And toxicosis decreases: therefore, in most women, it disappears by the 12th week.
How to survive?
There are no common recipes for all: we are all different and each has its own reason for toxicosis. But still there are rules that help most women:
- Get more rest and sleep. Sleep whenever possible and the body asks. A woman with severe toxicosis is almost always helped by a sick leave of 5 days.
- Avoid long breaks in eating. Eat light and high-calorie meals every 3 hours. Banana, dates, dried fruits, sweet yogurt often help. It's not scary if there is a roll or a cookie. All this is quickly digested, assimilated and gives you energy. But it is better to refrain from meat, fish, fatty and multi-component dishes (for example, Olivier salad). It is a difficult food to digest and assimilate. You will have to experiment with fiber. During pregnancy, constipation is often due to a relaxed - in company with the uterus - intestines. And in this case, rough raw fruits and vegetables will start peristalsis and regulate stools, but in some they cause gas and unpleasant colic in the stomach. So you have to try.
- Nausea is very often especially pronounced in the morning, after sleep. This is due to the large hungry interval. To ease the feeling, try to have a light snack right before bed. If you get up at night to go to the bathroom, chew half a banana or a cracker along the way. And in the morning, waking up, still not getting out of bed, eat yogurt, cottage cheese, a bun. Lie down for another 20 minutes. Then get up, have a light breakfast, and only then brush your teeth.
- The more dehydrated the body, the greater the intoxication. Start drinking in small sips, warm-hot, good quality water. Definitely between meals, not during. For taste, you can first add lemon or lime, you can buy mineral water in a glass in a pharmacy and drink it, preferably after stirring and releasing gases from the bottle. But if you haven’t drank water before, or drank it very little, then you shouldn’t abruptly start drinking more of it.
Medical treatment of early toxicosis also takes place, but only in severe forms!
And most importantly, remember that this state, although unpleasant, is temporary, absolutely safe for both you and the child. It will go away on its own very soon. And you will no longer feel like a weakened, sick pregnant woman, but will feel your pregnancy as a big, important and very joyful “work”.
Toxicosis, how to relieve the symptoms? - MC ADONIS in Kyiv
Many women mistakenly consider morning sickness in early pregnancy as a normal physiological process. Most often, this diagnosis means mild morning sickness, occasional vomiting, increased sensitivity to smells and tastes of food. It is believed that these symptoms are not dangerous and go away by the second trimester. However, this is a misconception: with severe toxicosis, complications can develop that increase the risk of abortion and a severe deterioration in a woman's health.
In the medical environment, the diagnosis of toxicosis means, in addition to nausea and vomiting, a whole range of pathological changes in the state of a pregnant woman during the first trimester. Symptoms of toxicosis are only an external manifestation of complex processes inside the female body. According to statistics, it develops in almost 90% pregnant. Despite the fact that this syndrome is not a natural process, its mild manifestations began to be considered one of the variants of the norm.
At what terms of pregnancy does toxicosis develop?
Toxicosis can last for several months - up to 13 or 16 weeks of pregnancy.
In the last trimester of pregnancy, preeclampsia may develop in women, which is mistakenly called late toxicosis. This is a serious complication of pregnancy, which is accompanied by an increase in blood pressure, deterioration of the cardiovascular system, kidneys and brain.
Symptoms of toxicosis
Contrary to popular belief, toxicosis in pregnant women has a lot of symptoms, but some of them develop only in moderate or severe cases.
This condition may be accompanied by:
- Increased salivation;
- Nausea;
- Vomiting;
- Dermatoses;
- Muscle cramps;
- Osteomalacia, or softening of the bones;
- Jaundiced;
- Bronchial asthma and other pathological changes in the body.
The most common symptoms are nausea and occasional vomiting. They occur in most pregnant women. In addition, short-term nausea and vomiting up to 1-2 times a day for a period of less than 13 weeks is referred to as a variant of the norm.
Other symptoms are moderate to severe. At the same time, the state of health of the pregnant woman deteriorates greatly and urgent hospitalization may be indicated for her.
Why early toxicosis is dangerous
Vomiting in pregnant women is one of the manifestations of early toxicosis. However, in the International Statistical Classification of Diseases and Related Health Problems (ICD), it is separated into a separate unit.
According to the frequency of attacks, vomiting is divided into 3 degrees:
- Mild - less than 5 times a day;
- Medium - 5-10 times a day;
- Severe - up to 20-25 times a day.
If a pregnant woman vomits more than 1-2 times a day every day, she should definitely seek medical attention. This condition can provoke severe dehydration of the body and the development of other pathological processes.
With the development of mild vomiting due to dehydration, a pregnant woman can lose up to 1-3 kg of weight per week (up to 5% of her body weight). With moderate severity, when vomiting with bile is repeated from 6 to 10 times a day, weight loss can reach 3-5 kg within a week or one and a half. Also, against this background, a woman's body temperature may increase, blood pressure decrease, pulse rate and acetone levels in the urine increase. The same, only to a greater extent, occurs with severe vomiting. In this case, due to fluid loss and complete indigestion of food, weight loss can reach 8-10 kg per week. Patients with severe vomiting are usually hospitalized and temporarily transferred to parenteral nutrition.
With profuse vomiting in pregnant women occurs:
- Violation of all metabolic processes in the body;
- Wasting and weight loss due to dehydration and malnutrition;
- Production of ketone bodies (molecules similar to acetone), the increase of which is dangerous for the liver and kidneys;
- Degenerative changes in the liver, kidneys, lungs and heart.
In rare cases, due to the constant urge to vomit in women, a retrotracheal hematoma may appear, localized between the walls of the uterus and the fetal egg. Against this background, as well as the general weakening of the body and the development of pathological processes, the risk of abortion increases.
No less dangerous is increased salivation. During the day, it can lead to the loss of more than 1 liter of fluid by the body.
In case of severe vomiting or the appearance of other symptoms of pathological disorders in the body, such as convulsions or shortness of breath, an urgent consultation with a gynecologist is recommended for a pregnant woman, who will diagnose and determine the tactics of treatment.
Causes of toxicosis in pregnant women
The exact cause of toxicosis during pregnancy has not been established. To date, there are several hypotheses.
The main ones are:
- Neuro-reflex;
- Hormonal;
- Immune;
- Psychogenic.
According to the neuro-reflex theory, during pregnancy, the work of the subcortical part of the brain increases, where the centers responsible for smell, salivation, stomach function and others are located. Because of this, the pregnant woman allegedly develops nausea and vomiting, as well as mood changes.
Supporters of the hormonal theory argue that toxicosis develops due to changes in the hormonal background as a result of the appearance of a new organ - the placenta. It is in it that human chorionic gonadotropin (hCG) is produced, by increasing the content of which in the blood, the onset of pregnancy is determined in the first weeks. The evidence for this theory is the coincidence of the highest level of hCG in the blood with the onset of nausea and bouts of vomiting.
According to the immune theory, nausea in pregnant women is associated with the body's reaction to a foreign body, which is the embryo.
Psychogenic theory is based on emotional causes. It is believed that nausea occurs due to stress and anxiety that a woman experiences during pregnancy. In the scientific community, this theory has the fewest supporters.
Although the exact cause of toxicosis has not been confirmed, experts have identified risk factors for its development, namely:
- Diseases of the gastrointestinal tract, liver and thyroid gland;
- Chronic inflammatory diseases of the genitourinary system;
- Past abortions;
- Asthenic body type;
- Frequent stress;
- Unbalanced diet.
Multiple pregnancy is also considered a risk factor.
Methods of treatment and prevention
If frequent vomiting or other alarming symptoms appear, the obstetrician-gynecologist who manages the pregnancy prescribes a general analysis of urine and blood to the woman. Based on their results, he determines the degree of toxicosis, on which the treatment tactics depend. In severe cases, accompanied by severe vomiting, a woman may be referred for hospitalization, and in mild cases, medication may be prescribed and recommended to adhere to certain rules.
Generally, women are advised to:
- Eat right, respecting the intake of proteins, fats and complex carbohydrates;
- Divide meals into 5-6 meals;
- Have breakfast immediately after waking up without getting out of bed;
- Drink plenty of water and herbal teas if they are well absorbed.
The same rules can be followed for prevention.
