If you are pregnant and have a fever, take your temperature right away and drink fluids, rest and call your physician if your temperature is greater than or equal to 100.4°F (38°C). Fever can indicate an infection, so seek medical attention promptly to protect yourself and your unborn child.
You’ll be concerned about your baby as well as yourself when you get a fever while you are pregnant.
The good news is that most fevers can be treated safely with the right care and support at your Primary Care Clinic.
Why Does Fever During Pregnancy Matter?
Fever is important during pregnancy because high body temperature can impact how a baby develops inside of you, especially during the first trimester.
Pregnancy changes how the immune system functions; therefore, when you are pregnant, your body is more susceptible to getting an infection, so the symptoms will be present for longer than if you were not pregnant.
Most mild fevers are not a cause for concern; however, a long-lasting fever or a fever greater than 101.5°F (38.5°C) should be evaluated by a doctor because it could be a sign of an infection.
For this reason, many women visit Primary Care Las Vegas for a quick evaluation and reassurance.
What Is Considered a Fever While Pregnant?
A fever while pregnant is typically defined as a body temperature that is greater than or equal to 100.4 degrees Fahrenheit (38 degrees Celsius). To clarify, here is a breakdown of the various conditions of body temperature by degree:
- Normal – 98.6 (average)
- Slight fever – 99.5 to 100.3 degrees
- Fever – 100.4 degrees or greater
- High fever – over 102 degrees
- Emergency (requires immediate medical attention) – over 103 degrees
If your temperature increases quickly or remains at a high level, it is important to get to a Primary Care Clinic immediately.
How Do You Know If You Have a Fever?
You will know if you have a temperature through the use of a thermometer, which can be done by either using;
- Mouth (oral)
- Forehead (temporal)
- Ear (tympanic)
- Armpit (axillary)
- Rectum (rectal)
Both types of thermometers are acceptable; however, the most important thing is to ensure that they are accurate. Therefore, if you feel hot, cold, or like you are sick, do not make a guess at what your temperature might be. Instead, measure it and keep track of how it changes.
What Are Common Symptoms of Fever in Pregnancy?
The signs of fever during pregnancy are largely the same as in all other individuals. Common signs of fever during pregnancy include:
- Chills and/or shivering
- Sweating
- Feeling hot
- Muscle pain and/or weakness
- Not drinking enough fluids (dehydration)
- Loss of appetite
- Irritability
If symptoms are severe, using the services of Primary Care Las Vegas can help you identify the cause quickly.
Can Having a Fever While Pregnant Hurt the Baby?
During pregnancy, especially in the first trimester, developing a high fever may be associated with increased risk for the developing fetus.
According to competitor analysis: fever alone is not always bad, but the temperature level of the fever and the cause of the fever are both important.
Risks associated with high fevers: include but are not limited to;
- Neural tube defects (especially early in pregnancy)
- Congenital anomalies
- Miscarriage (especially if the fever is high)
- Early labor/tachycardia (later on in pregnancy)
Most of the time low-grade fevers are short-lived but it’s always better to get checked out by your doctor.
Why Do Pregnant Women Get Fevers?
Fever is an indication that the body has an ongoing infection.
Common reasons for fever include:
- Cold/flu
- COVID-19
- Stomach virus
- Food poisoning
- Ear infection
- Urinary tract infection (UTI)
- Kidney infection
- Genital infections
There are also some rare but very serious reasons for fever;
- Listeriosis
- Toxoplasmosis
- Encephalitis (inflammation of the brain)
Your primary care physician (PCP) can help determine the cause of the fever before complications develop.
What Should You Do Right Away If You Have a Fever While Pregnant?
You should take action immediately and utilize safe home remedies and medical support whenever you develop a fever during pregnancy, this is very important!
According to the experts:
Rest in a cool, comfortable room.
Your body will recover faster from fever and reduce the load on your immune system
Be in a well-ventilated area and do not overheat by using heavy blankets
Wear lightweight, breathable clothing
Drink Plenty of Fluids
Staying hydrated is a fundamental part of fighting fever during pregnancy. When you’re running a fever, you lose fluids through sweating. Good fluids to drink include:
- Water
- Electrolyte drinks
- Warm soup
- Fruit juices (e.g., orange juice)
By drinking fluids regularly throughout the day, you help counteract the loss of fluids due to the fever and keep the symptoms from getting worse.
Use Cool Compresses
A cool washcloth can be placed on the forehead to relieve discomfort. Some women choose to wipe the body down with lukewarm water, especially focusing on:
- Neck
- Armpits
- Groin
It is important that you do not take a cold bath because it can cause shivering and increase the temperature again.
Take Pregnancy-Safe Fever Medication
Take Fever Medication Suitable for Pregnancy
Acetaminophen (Tylenol) is the safest fever-reducing medicine to take when you are pregnant. Most providers recommend using it if the fever is higher than 100.4°F. Do not use the following medicines unless your provider prescribes them:
- Ibuprofen (Motrin, Advil)
- Aspirin (except for low-dose recommended for preeclampsia)
- Herbal remedies for reducing fevers
Be sure to talk with your Primary Care Provider in Las Vegas before taking any fever reducer medication.
When Should You Call a Doctor for Fever During Pregnancy?
You should call your doctor if you are pregnant and have any fever. You need to get immediate medical attention if you have:
- A fever of 102–103°F or higher
- A fever that stays for longer than 24 hours
