Doctors consider a temperature of 100.4°F and over to be a fever indicating that your body is fighting an infection. A fever during pregnancy is no different from a regular fever, except that it may carry some risks or be indicative of a pregnancy-related complication (1). Now, before you get stressed out any further, you need to understand that not every instance of fever is dangerous. Most of the time it is easily resolved without any harm to you or your growing baby.

The important thing to do is to promptly identify the underlying cause and get it treated. This guide can help you understand the different reasons behind fever in pregnancy period, and what you can do about it.

Common Causes Of Fever During Pregnancy

  • Urinary Tract Infection (UTI)
A urinary tract infection may cause fever during pregnancy


UTIs or urinary tract infections are quite common during pregnancy and can present fever as a symptom. Your urinary tract comprises your kidneys, ureters, bladder, and urethra, and an infection may develop from bacteria that get into this system. Most urinary tract infections occur in the bladder and can present other symptoms besides fever, like (2):

  • Strong urge to urinate
  • Burning sensation while urinating
  • Chills
  • Pelvic pain
  • Cloudy urine
  • Blood in the urine

If UTIs are left untreated, the infection may reach the kidneys and cause serious complications including preterm labori  XEarly labor, which occurs before 37 weeks of pregnancy. It may lead to bigger hazards to the baby's health. , low birth weight in babies, and even sepsisi  XLife-threatening condition that develops when the body's response against an infection destroys its own tissues. (3).

  • Influenza

Pregnancy puts you at a greater risk of catching the flu and getting severely sick from it as your immune system is naturally suppressed (4). Some common symptoms of flu or influenza are (5):

  • Sudden high fever
  • Chills
  • Coughing
  • Nausea
  • Vomiting

Flu should be treated and monitored to reduce the risk of serious complications. As flu can make you really ill, the CDC recommends that all pregnant women should take the flu shot (6).

  • Upper Respiratory Infection

A viral infection in the upper respiratory tract, or the common cold, can be another reason behind a fever in pregnancy. While an upper respiratory tract infection has similar symptoms as the flu, they are generally not as severe and tend to resolve by themselves, generally within two weeks. Some additional symptoms that may distinguish a common cold from the flu are (7):

  • Low-grade fever
  • Runny nose
  • Sore throat
  • Breathing difficulty

You may be able to treat the common cold with home remedies. However, if your symptoms do not improve, get in touch with your doctor as URI in pregnancy may be associated with behavior problems in childhood (8).

  • Gastroenteritis

Gastrointestinal infection may cause fever in pregnancy, and it may present with more worrying symptoms like diarrhea and vomiting. Dehydration resulting from these can have serious consequences as it may cause contractions or preterm labor (9), (10).
Low blood pressure, dizziness, weakness, fainting, and electrolyte imbalance are some other serious side effects of a gastrointestinal infection. You should immediately contact the doctor in the following situations (11):

  • There is blood in your vomit.
  • You have signs of dehydration like thirst, dry mouth, dizziness, low urine output.
  • You have a fever above 101 °F.
  • You cannot drink or eat anything without throwing up for 24 hours.
  • There is blood in your stool.

It is best to keep your ob-gyn informed about your condition to avoid the risk of complications. You should drink plenty of fluids and may change to a bland or BRAT (bananas, rice, applesauce, toast) diet as a natural way to support your prescribed treatment.

Depending on what the reason behind your pregnancy fever is, you may need to work with your ob-gyn, even when it comes to over-the-counter medications. That’s because some commonly used OTC medicines to treat fever and other symptoms may not be safe during pregnancy. Besides this, there are a number of things you can do at home to help get rid of fever naturally.

You need to contact your doctor when your fever does not subside after trying the natural remedies or if you have accompanying symptoms indicating a serious underlying condition.

Besides the common causes of fever that may affect you during your pregnancy, there are a few medical conditions that affect only pregnant women and may cause fever-like symptoms. These conditions require prompt medical attention as they may cause unwanted complications. Some of them are (1):

  • Chorioamnionitis

This is a medical condition characterized by a bacterial infection in the membranes (chorion and amnion) that surround the fetus as well as the amniotic fluid. Fever, chills, sweating, rapid heartbeat, unusual vaginal discharge, and a tender uterus are common symptoms of chorioamnionitis.
If left untreated, this can lead to serious complications for both the mother and baby (12).

  • Listeria

Listeria is a serious infection that may result from the consumption of contaminated food or water. Fever is one of the earliest symptoms of listeria. Other signs include muscle ache, nausea, and diarrhea. The infection can spread to the nervous system if not treated promptly and may cause loss of balance, headache, stiff neck, confusion, and convulsionsi  XMedical condition in which the body's muscles contract violently and involuntarily due to abnormal electrical activity in the brain. . Not all cases of listeria cause harm to the unborn child, but in some, there is the risk of miscarriage, premature delivery, severe infection in the newborn, and even stillbirth (13).

  • Fifth Disease Or Parvovirus B19

Parvovirus B19 is rare in pregnant women, however, if contracted, it may lead to miscarriage or cause the baby to be born with severe anemia. Fever may or may not accompany joint pain, which is the most common symptom of Parvovirus B19 in adults (14).

Depending on your diagnosis, your doctor can prescribe you the course of treatment keeping in mind both your and your baby’s health. You can take a glimpse at some common medical treatment options for a fever during pregnancy.

Medical Ways To Treat A Fever While Pregnant

  • For fever related to a viral infection, your doctor may ask you to take acetaminophen, commonly available as Tylenol. In addition, he may prescribe an antiviral medication.
  • For a bacterial infection, your doctor will prescribe you a course of antibiotics to stop the spread of the infection.
  • Your doctor may also prescribe you additional drugs for the symptomatic treatment depending on the medical condition that is causing your fever.
Did You Know?
Acetaminophen, used to treat fever and mild to moderate pain, was first synthesized by H.N. Morse, an American chemist, in 1878.

Note: A 2018 study showed that maternal fevers, especially in the second trimester, might be associated with autismi  XNeurological disorder caused by differences in the brain that impacts how people behave, engage with others, and communicate. . More frequent fevers were found to increase the likelihood further. Women who took anti-fever medication during pregnancy were less likely to have autism in fetuses exposed to fever (15).

A fever during pregnancy can feel stressful, even with support and prescription medication. The best thing of course is to do as much as possible to lower your risk of getting it.
