If vomiting prevents you from keeping fluids down during pregnancy, it is important to assess your overall condition and ask your health care team for guidance.

Distinguish a passing discomfort from a concerning change

Nausea and occasional vomiting can occur during pregnancy. If your symptoms are mild and temporary and you can keep fluids down, mention them at your prenatal visit and follow the guidance you have received. A common discomfort, by itself, does not confirm that a complication is present.

Ask for guidance if vomiting makes it difficult to stay hydrated

Contact your prenatal care team soon if you vomit repeatedly, cannot keep fluids down, your symptoms worsen, or they interfere with your activities. If you also feel very weak, urinate much less than usual, or your overall condition worsens, seek urgent care. Whether an evaluation is needed depends on the severity and progression of your symptoms; do not wait until your next appointment if they continue or concern you.

Seek urgent care for fainting, confusion, or marked deterioration

Fainting, confusion, or marked deterioration requires urgent care. Ask someone to help you get care if you feel weak or confused. Do not attribute these symptoms to a specific cause or try to manage them at home on your own.

Tell your health care team if intense thirst or increased urination persists

Increased thirst or needing to urinate more often can have different causes during pregnancy; on its own, it does not confirm gestational diabetes or another diagnosis. Tell your health care team if the change is new, persists, or occurs with other symptoms. The team will decide whether an evaluation or tests are needed.

Do not stop medications on your own

When you ask for guidance, tell the team how many weeks pregnant you are, when your symptoms began, how long they last, and whether you can keep fluids down. Mention changes in the amount of urine you pass and the medications you take. This information can help the team guide you, but do not change or stop treatments without instructions.

If you need urgent care, prioritize getting help

If you faint, become confused, or experience significant worsening, go to an emergency department or ask someone to help you get there. If you are in Colombia, seek an available emergency care service and clearly state that you are pregnant and describe your symptoms. Do not delay care while trying to resolve administrative matters first.

Confirm the next step with your prenatal care team

If it is not an emergency, agree with your care team on whether you need an evaluation and when to follow up. Write down relevant changes, and ask for guidance again if you get worse or develop an urgent warning sign. This guide is educational and does not replace an individual evaluation.

When to seek medical care

If symptoms persist, test results are abnormal, or you have questions about medication, arrange an individual assessment. Do not change treatment or doses without medical guidance.

Frequently asked questions

Does being very thirsty mean I have gestational diabetes?

No. Increased thirst can have different causes and cannot, by itself, diagnose gestational diabetes. If it persists or occurs along with other changes, tell your prenatal care team so they can assess what to do.

Should I wait until my next appointment if I am vomiting?

If the vomiting is occasional and you can keep fluids down, you can mention it at your prenatal follow-up. If you vomit repeatedly, cannot keep fluids down, or get worse, contact your care team soon; seek urgent care if you also feel very weak, urinate much less than usual, faint, or become confused.

What information should I provide when I ask for help?

Tell them how many weeks pregnant you are, what symptoms you have, when they began and how long they last, whether you can keep fluids down, any changes in the amount of urine you pass, and what medications you take. If you have severe warning signs, prioritize getting urgent care.
