I’m Pregnant and Throwing up Yellow

Most pregnant women throw up a yellow liquid first thing in the morning before eating anything. This symptom is expected during the early stages of pregnancy and is known as morning sickness or reflux.

The yellow vomit contains a fluid that is produced by your liver and stored in your gallbladder. This liquid, also known as bile, is responsible for breaking down fats into fatty acids during digestion. Bile has a bitter taste, and that is why the yellow vomit tastes bitter. Sometimes the yellow vomit may turn clear if you throw up after drinking water.

Why Being Pregnant Makes You Throw up Yellow

Vomiting yellow during pregnancy is linked to an increase in hormones needed for a healthy pregnancy. These hormonal changes also cause you to feel nauseated and uncomfortable during the morning sickness.

When you become expectant, your placenta produces the human chorionic gonadotropin (HCG) hormone. If your HCG is high, you will likely experience throwing up yellow more often than women with low HCG.  Your estrogen levels also contribute to increased nausea and throwing up when you are pregnant.

Is Throwing up Yellow When You Are Pregnant Good or Bad?

Though throwing up is common with most pregnant women, not throwing up during pregnancy isn’t a cause for concern. Most pregnant women will admit that there is nothing good about feeling nauseated and throwing up yellow in the morning.

However, women who vomit in the first trimester during pregnancy are less likely to experience miscarriages.  It is also speculated that vomiting helps pregnant women eliminate toxins from their bodies, which keeps the baby healthy. Nevertheless, vomiting is not always an indication of a healthy pregnancy.

When Does Throwing up Yellow Stop During Pregnancy?

Throwing up yellow during pregnancy may not go away until your baby is born. Nevertheless, this may vary between women.  

For some, nausea and throwing up yellow is worse during the first trimester and goes away by the fourteenth week. By the twentieth week, most pregnant women will have stopped throwing up yellow in the morning.

What Can You Eat After Throwing up Yellow

Throwing up yellow during pregnancy is often accompanied by feeling nausea. Eating some foods, especially oily treats, may cause you to throw up more. When you are pregnant, you tend to be choosy about foods, and what previously had an irresistible smell to you may now be unbearable.

However, snacks like plain biscuits or crackers can help you feel better. If you can, also try eating nuts and apples before getting out of bed to give you some relief with nausea.

Drinking water in small amounts during the night can help you stay hydrated. Again, depending on your tolerance, you may add ginger or slices of lemon and some mint leaves for flavor. If ingesting water is still hard for you, take some soda or ginger ale.

What Not to Do After Throwing up Yellow

Stomach juices that you throw up as yellow vomit contain bail acids and pigments that temporarily soften the enamel on your teeth. The bitter taste of yellow vomit in your mouth makes you want to brush your teeth immediately. However, doing so may damage your enamel. You can ease up the bitterness by sucking on some ice.

When to Worry if You Are Pregnant and Throwing up Yellow

Even though morning sickness accompanied by nausea and throwing up yellow is common in most pregnant women. You may have cause to see a doctor if you excessively throw up during pregnancy.

In most cases, you are not expected to lose weight when pregnant, but it may be a sign of a more serious issue if you do. Throwing up immediately after eating or drinking or finding it hard to eat and drink may indicate that you have a condition called hyperemesis gravidarum (HG).


Most pregnant women will feel nauseated and throw up yellow in the morning. For some, this may stop after the third month, but others have this experience throughout the entire pregnancy term. 

However, if throwing up yellow becomes excessive and you notice that you have lost weight, you may need to see your doctor. It is a worrisome situation if you have a fever, see blood in your vomit, and can’t keep down food for at least 24 hours.
