Why Do I Vomit After Drinking Water During Pregnancy?

Vomiting after you drink water while pregnant is a reasonably common downside to pregnancy. Your raised hormone levels are believed to be the cause, and you can reduce the frequency of vomiting by making some lifestyle and dietary changes without compromising your water intake.

Many pregnant women feel nauseous, especially in the first trimester of their pregnancy. This is commonly known as morning sickness and can happen at all times of the day, not just in the morning, as the name suggests.

Morning sickness can continue periodically throughout your pregnancy and can be debilitating if left unchecked.

Pregnant moms are advised to stay hydrated during their pregnancy, and drinking water is a standard recommendation.

So, vomiting after you drink water will be concerning. Understanding why this happens can help you manage your symptoms and alleviate this problem.

Read on to learn about common causes of vomiting during pregnancy and what you can do to have a happier pregnancy.

Understanding Pregnancy and Vomiting

Pregnancy is a beautiful and challenging time for many women. It is a period of significant hormonal changes that can lead to various symptoms, such as nausea and vomiting. This is common during pregnancy and affects up to 80% of pregnant women.

Keep in mind that a lack of nausea and vomiting during pregnancy isn’t cause for concern. Some pregnant moms never experience morning sickness.

The most common form of vomiting during pregnancy is morning sickness, which typically occurs during the first trimester and is characterized by nausea, vomiting, and fatigue.

Morning sickness is believed to be related to rising hormone levels in your body, particularly human chorionic gonadotropin (HCG).

Interestingly,  studies have shown that pregnant moms who experience nausea and vomiting during their first trimester have a lower risk of miscarriage than moms without these symptoms.

Severe morning sickness, known as hyperemesis gravidarum, results from increased levels of HCG and can lead to weight loss, dehydration, and other complications.

It is estimated that 0.5-2% of pregnant women experience hyperemesis gravidarum.

Underlying medical conditions or being pregnant with twins or multiples may increase the likelihood of vomiting during pregnancy.

It is important to note that in most cases, vomiting during pregnancy is not harmful to your baby. However, severe nausea or excessive vomiting is concerning, and it is best to seek medical attention.

Causes of Vomiting After Drinking Water

Vomiting after drinking water is a common symptom during pregnancy, which may result from:

1. Hormonal changes

These changes can affect your digestive system, making it more sensitive to certain foods and drinks, including water.

2. Dehydration

When dehydrated, your body tries to conserve water by reducing urine output. This can lead to a buildup of waste products in your body, which can cause vomiting.

3. Drinking Water Too Quickly

Drinking water too quickly can cause your stomach to become bloated, triggering the vomiting reflex.

4. Acid Reflux

Acid reflux occurs when stomach acid flows back into your esophagus, causing a burning sensation in your chest, which can cause nausea and vomiting after drinking water.

5. Foodborne Illness

It is typically caused by eating food contaminated with bacteria, viruses, or parasites, which can cause nausea, vomiting, and diarrhea. Drinking water may exacerbate your symptoms.

6. Germs

Drinking water contaminated with germs can result in an infection in your digestive system and cause vomiting.

If your symptoms persist or worsen, seek medical help.

Symptoms and risk factors

Vomiting after drinking water during pregnancy can, in some cases, be a sign of a more severe condition.


  • Nausea and vomiting are the most common symptoms and can occur at any time of the day or night and can also be severe in some cases.
  • Weakness and fatigue due to the loss of fluids and nutrients.
  • Dizziness and light-headedness can occur due to dehydration and low blood pressure.
  • Headaches can occur as a result of dehydration and a lack of nutrients.
  • Vomiting can cause digestive issues, leading to constipation or diarrhea.
  • Dehydration can cause your heart to beat faster than usual.

Risk Factors

  • Hyperemesis gravidarum: This is a severe form of morning sickness and can cause excessive vomiting, weight loss, and dehydration.
  • Liver damage: Severe vomiting can lead to liver damage, which can cause symptoms such as jaundice, fatigue, and abdominal pain.
  • Low blood pressure: Dehydration can cause low blood pressure, which can lead to dizziness, fainting, and other symptoms.

Impact on mother and baby

Vomiting can have a significant impact on both you and your baby, which may include:

  • Frequent vomiting can lead to weight loss.
  • Vomiting can be exhausting, and it can be challenging to get enough rest when you are frequently vomiting.
  • Severe vomiting can lead to complications such as dehydration.

Diagnosis and Treatment

If a diagnosis of hyperemesis gravidarum is made, your doctor will prescribe medication that can help alleviate your symptoms.

In addition, your doctor may also recommend lifestyle changes to help manage your symptoms, which may include:

  • Eating small, frequent meals throughout the day instead of three large meals.
  • Avoiding triggers that may worsen your symptoms, such as strong smells or certain foods.
  • Staying hydrated by sipping fluids throughout the day.
  • Resting as much as possible.

If your symptoms are severe and you are unable to keep fluids down, you may need to be hospitalized for treatment, where you will receive intravenous fluids and medications to help manage your symptoms.

With proper diagnosis and treatment, most pregnant moms with hyperemesis gravidarum can manage their symptoms and have a healthy pregnancy.

Dietary adjustments and lifestyle changes

Making some dietary adjustments and lifestyle changes can help reduce the chances of vomiting after drinking water during pregnancy.

Drinking small amounts of water throughout the day can help you stay hydrated without overwhelming your stomach. You can also try drinking other recommended fluids like coconut water, diluted fruit juice, or ginger tea.

Eating small, frequent meals throughout the day helps to keep your blood sugar levels stable and prevents nausea.

Include plenty of fruits, vegetables, and whole grains in your diet. Bland foods like crackers, toast, or rice can help settle your stomach and reduce nausea. Avoid spicy, greasy, or fatty foods, which can make nausea worse.

Making some lifestyle changes can also help reduce the chances of vomiting.

Getting plenty of rest, avoiding stress, and doing gentle exercises like walking or yoga can all help reduce nausea.

Tips for staying hydrated

Staying hydrated during pregnancy is crucial, especially if you experience severe morning sickness. Here are some tips to help you drink enough water and prevent dehydration:

1. Drink enough water

Drinking enough water is the most important thing you can do to stay hydrated. Aim to drink at least 8-10 cups of water per day or more if you feel thirsty.

2. Use a straw

If you find it challenging to drink water from a glass, try using a straw. Sipping through a straw can help you drink water more with ease.

3. Add electrolytes

Electrolytes are an effective way to rehydrate. You can buy electrolyte supplements or drink sports drinks that contain electrolytes.

4. Watch for signs of dehydration

Signs of dehydration include dark yellow urine, dry mouth, fatigue, and dizziness. If you notice any of these symptoms, drink more water and raise this concern with your doctor.

Alternative therapies

While there is no one-size-fits-all solution, there are a few alternative therapies that have been known to help some pregnant moms.


Acupuncture is an ancient Chinese practice that involves inserting thin needles into specific points on the body to stimulate energy flow.

Some women have found that acupuncture can help reduce nausea and vomiting during pregnancy. However, it’s essential to find a licensed and experienced practitioner who is trained in working with pregnant women.


Acupressure is like acupuncture, but instead of needles, pressure is applied to specific points on the body.

One popular acupressure point for reducing nausea is located on the wrist, about three finger-widths down from the base of the hand.

You can try applying pressure to this point by using your thumb and middle finger or by wearing acupressure wristbands.

Ginger Ale

Ginger is a known natural remedy for nausea and vomiting, and ginger ale can be a refreshing way to help ease your symptoms. Look for ginger ale that contains raw ginger, as some brands may only use artificial flavoring.


How can I handle vomiting during pregnancy?

Try to stay hydrated by drinking water or other fluids and eating small, frequent meals throughout the day.

Additionally, avoid foods and smells that trigger your nausea, get plenty of rest, and try relaxation techniques like deep breathing or yoga.

What causes vomiting during pregnancy?

Vomiting during pregnancy is often caused by the increased levels of hormones in your body.

The hormone human chorionic gonadotropin (HCG) is produced by the placenta and can cause nausea and vomiting.

Other factors that can lead to vomiting during pregnancy include certain smells, foods, and stress.

What are some remedies for yellow vomit during pregnancy?

Yellow vomit during pregnancy can be a sign of dehydration or an empty stomach.

Try sipping on clear fluids like water, ginger ale, or broth. Eating small, frequent meals and avoiding foods that trigger your nausea can also help.

If you continue to experience yellow vomit, talk to your healthcare provider.

What is hyperemesis gravidarum? How is it treated?

Why does water make me nauseous during pregnancy?

Water may make you nauseous during pregnancy due to the changes in your body’s hormones and digestive system.

Drinking water that is too cold or too hot can also upset your stomach. Try drinking water at room temperature or adding a slice of lemon or cucumber for flavor.

Should I drink water after throwing up while pregnant?

If you have vomited while pregnant, it is essential to stay hydrated by drinking water or other clear fluids.

However, it is best to wait at least 30 minutes after vomiting to drink water to avoid further irritation to your stomach.

Sipping on small amounts of water throughout the day can also help you stay hydrated.
