Drinking water and staying hydrated are important parts of a healthy pregnancy. Pregnant people need more water than those who are not pregnant and risk losing more water throughout the day.

Pregnant people are at risk of becoming dehydrated in the first, second, or third trimester. Dehydration during pregnancy raises the risk of serious health problems for both the pregnant person and the fetus. Staying hydrated can help a parent’s body meet the increased needs of pregnancy.

Chronic, untreated dehydration during pregnancy raises the risk of the following complications:

Rehydrating With Electrolytes in Water

To prevent dehydration, most pregnant people need to drink eight to 12 glasses (64 to 96 ounces) of water per day.Once the body is dehydrated, it may be helpful to rehydrate with both water andelectrolytes. Electrolytes are essential minerals that the body needs to function.

Minor Dehydration Treatment in Pregnancy

Most pregnant people can safely treat mild dehydration at home. Call your healthcare provider if you have any concerns about your symptoms or the status of your fetus.

To treat minor dehydration, rest in a cool area and replace fluids. Drink water, a sports drink, or an oral rehydration solution like Pedialyte. If your symptoms do not improve, call your healthcare provider.

Severe Dehydration Treatment in Pregnancy

People with severe dehydration should see their healthcare providers or seek treatment in the emergency department. Your healthcare team will assess your hydration status with a physical exam, vital signs, a urine test, and blood tests.

People with severe dehydration usually require IV fluids to quickly replace fluids. This is especially helpful for people who are too nauseated to drink water.

Severe Morning SicknessSome pregnant people experience severe morning sickness, known ashyperemesis gravidarum, that puts them at high risk of dehydration. If you are unable to drink water due to nausea, try chewing on ice chips. If you experience uncontrolled nausea or vomiting, talk with your healthcare provider right away.

Risks of dehydration during pregnancy include low amniotic fluid levels and preterm contractions. Early symptoms may include decreased urine output, thirst, and dry mouth. Serious symptoms may include dizziness, confusion, fainting, and low blood pressure.

Fortunately, it is possible to treat and prevent dehydration. Drink water throughout the day, and avoid drinks with caffeine or sugar. Take frequent breaks when spending time in the heat.

If you develop signs of dehydration, rest and drink water or an electrolyte drink. If you develop serious dehydration symptoms, seek immediate medical treatment.
