A fever is not a typical symptom of morning sickness and usually indicates another underlying condition.
Understanding Morning Sickness and Its Symptoms
Morning sickness is a common experience during pregnancy, affecting up to 70-80% of pregnant women. Despite its name, it can occur at any time of the day. Characterized mainly by nausea and vomiting, morning sickness typically begins around the sixth week of pregnancy and often subsides by the end of the first trimester. However, its intensity and duration can vary widely among individuals.
The core symptoms include queasiness, occasional vomiting, food aversions, and increased salivation. These symptoms are primarily linked to hormonal changes, especially elevated levels of human chorionic gonadotropin (hCG) and estrogen. While unpleasant, morning sickness is generally harmless to both mother and baby.
It’s important to note that morning sickness itself does not cause fever. Fever is a response triggered by infections or inflammation in the body and signals that something else might be going on.
Why Fever Is Not a Direct Symptom of Morning Sickness
Fever results from your body’s immune system reacting to an infection or illness. It involves raising your core temperature to help fight off bacteria or viruses. Morning sickness, on the other hand, stems from hormonal fluctuations rather than infection.
Pregnancy hormones influence the digestive tract and brain centers controlling nausea but do not trigger immune responses that cause fever. In fact, if a pregnant woman experiences fever alongside nausea or vomiting, it’s usually a sign of an underlying infection such as:
- Urinary tract infections (UTIs)
- Influenza or other viral illnesses
- Gastrointestinal infections
- Other systemic infections
Recognizing this distinction is crucial for timely medical care because untreated infections during pregnancy can pose risks to both mother and fetus.
Common Causes of Fever During Pregnancy
Pregnancy can make women more vulnerable to certain infections due to immune system adjustments. Here are some common causes of fever in pregnant individuals:
- Viral Infections: Influenza, common cold viruses, and others can cause fever along with respiratory symptoms.
- Bacterial Infections: UTIs are frequent during pregnancy due to urinary tract changes; they often present with fever.
- Gastrointestinal Infections: Food poisoning or stomach bugs may cause fever with nausea and vomiting.
- Other Conditions: Less commonly, conditions like chorioamnionitis (infection of fetal membranes) can cause fever.
If fever accompanies morning sickness symptoms, it’s essential to seek medical evaluation promptly.
The Interplay Between Morning Sickness and Fever: What You Should Know
Though morning sickness itself doesn’t cause fever, the two can sometimes overlap coincidentally. For example:
- A pregnant woman experiencing typical morning sickness may catch a viral infection causing fever.
- Nausea caused by an infection may be mistaken for morning sickness.
- Severe vomiting from infections might mimic or worsen morning sickness symptoms.
This overlap complicates self-diagnosis but underscores why any fever during pregnancy requires thorough assessment.
Differentiating Between Morning Sickness and Infection-Related Symptoms
To tell if nausea is purely from morning sickness or linked to an infection causing fever:
| Symptom Aspect | Morning Sickness | Infection-Related Illness |
|---|---|---|
| Fever Presence | No fever or elevated temperature normally | Fever usually present (above 100.4°F / 38°C) |
| Nausea & Vomiting Timing | Tends to be consistent in early pregnancy; often worse in mornings but can occur anytime | Nausea/vomiting sudden onset; may accompany diarrhea or abdominal pain |
| Additional Symptoms | No chills; no body aches; generally no respiratory symptoms | Malaise, chills, muscle aches; cough or urinary symptoms may be present depending on infection type |
| Duration & Progression | Tends to improve after first trimester gradually | Symptoms worsen without treatment; may escalate quickly requiring intervention |
| Treatment Response | Mild relief with dietary changes and rest; no antibiotics needed | Treatment often requires antibiotics/antivirals depending on cause; supportive care essential |
This table highlights how careful evaluation helps distinguish between these two causes.
The Risks of Fever During Pregnancy: Why It Matters?
Fever in pregnancy demands attention because it carries potential risks for both mother and developing fetus. High maternal temperatures—especially above 102°F (39°C)—have been associated with increased chances of birth defects such as neural tube defects when occurring in early pregnancy.
Besides congenital risks, maternal fever can also lead to:
- Poor fetal growth due to impaired placental function.
- Preterm labor triggered by systemic inflammation.
- Maternal dehydration from excessive sweating combined with vomiting.
- An overall increase in discomfort that complicates prenatal care.
Prompt diagnosis and treatment reduce these risks significantly.
Treatment Approaches for Fever During Pregnancy with Nausea/Vomiting
Managing fever safely during pregnancy requires balancing symptom relief while protecting fetal health. Common strategies include:
- Mild Fever: Acetaminophen (paracetamol) is generally considered safe for reducing low-grade fevers.
- Treating Underlying Infection: Antibiotics prescribed must be safe for pregnancy (e.g., penicillins); antivirals chosen carefully when needed.
- Hydration & Nutrition: Replenishing fluids lost through vomiting prevents dehydration-related complications.
- Mild Anti-Nausea Measures: Dietary adjustments like small frequent meals help reduce nausea but don’t affect fever directly.
- Avoid NSAIDs: Drugs like ibuprofen are typically avoided especially in later trimesters due to fetal risks.
Close monitoring by healthcare providers ensures both maternal comfort and fetal safety.
The Role of Healthcare Providers When Fever Appears With Morning Sickness Symptoms
If you’re wondering “Can You Get A Fever From Morning Sickness?” remember that any fever during pregnancy should prompt immediate consultation with your healthcare provider.
Doctors will typically perform:
- A thorough history focusing on symptom onset and progression.
- A physical exam including vital signs assessment—temperature being critical here.
- Labs such as urine tests for UTIs, blood tests for markers of infection/inflammation, sometimes cultures if needed.
- Prenatal ultrasounds if fetal well-being needs checking amid maternal illness.
- A tailored treatment plan addressing both nausea/vomiting relief and infection management if present.
Early intervention minimizes complications while providing reassurance.
The Importance of Self-Monitoring During Pregnancy Illnesses
Pregnant women should keep track of key signs including:
- The presence or absence of fever using a reliable thermometer daily if feeling unwell.
- The frequency and severity of nausea/vomiting episodes beyond typical morning sickness patterns.
- The appearance of new symptoms like chills, body aches, urinary discomforts, or respiratory issues.
Keeping a symptom diary aids communication with healthcare providers for accurate diagnosis.
The Science Behind Why Morning Sickness Doesn’t Cause Fever
Hormones such as hCG rise sharply in early pregnancy triggering nausea centers in the brainstem but do not stimulate pyrogens—substances that induce fever—in the hypothalamus. Instead:
- Nausea results from altered gastrointestinal motility and central nervous system sensitivity influenced by hormones like estrogen and progesterone.
Fever requires activation of immune pathways involving cytokines such as interleukin-1 (IL-1), tumor necrosis factor-alpha (TNF-α), which are absent in normal pregnancy hormonal changes causing morning sickness.
This distinction clarifies why temperature elevation does not accompany standard morning sickness symptoms.
Treating Severe Nausea Without Confusing It With Infection-Induced Symptoms
Some women experience hyperemesis gravidarum—a severe form of morning sickness leading to dehydration and weight loss—but still without fever unless complicated by infection.
Treatment options include:
- Intravenous fluids for rehydration when oral intake fails;
- Nutritional support via vitamin supplementation;
- Mild antiemetics approved for use during pregnancy like doxylamine-pyridoxine combinations;
These measures focus solely on alleviating nausea without addressing infection since no fever is involved here.

Frequently Asked Questions
Can You Get A Fever From Morning Sickness?
A fever is not a typical symptom of morning sickness. Morning sickness mainly causes nausea and vomiting due to hormonal changes, but it does not trigger an immune response that leads to fever.
If you experience a fever during morning sickness, it may indicate another underlying condition such as an infection.
Why Does Morning Sickness Not Cause Fever?
Morning sickness results from hormonal fluctuations, particularly elevated hCG and estrogen levels, which affect nausea centers in the brain. These changes do not involve the immune system, so they do not cause fever.
Fever usually signals infection or inflammation, which is unrelated to the causes of morning sickness symptoms.
What Should I Do If I Have A Fever Along With Morning Sickness?
If you have a fever along with morning sickness symptoms, it’s important to seek medical advice promptly. Fever may indicate infections like urinary tract infections or viral illnesses that require treatment during pregnancy.
Early diagnosis helps protect both you and your baby from potential complications.
Are There Common Infections That Cause Fever During Morning Sickness?
Yes, pregnant women are more vulnerable to infections such as urinary tract infections, influenza, and gastrointestinal infections. These can cause fever alongside nausea and vomiting similar to morning sickness.
Distinguishing between morning sickness and infection-related symptoms is important for appropriate care.
Can Morning Sickness Symptoms Mask A Fever?
While morning sickness itself doesn’t cause fever, its symptoms like nausea and vomiting might make it harder to notice a mild fever initially. Monitoring your temperature during illness is important.
If you suspect an infection or persistent fever during pregnancy, consult your healthcare provider for evaluation and treatment.
The Impact Of Misinterpreting Fever And Morning Sickness Symptoms
Misattributing a genuine febrile illness as just “bad morning sickness” delays necessary treatment which could worsen outcomes. For example:
- A urinary tract infection left untreated might progress into kidney infections requiring hospitalization;
Hence awareness about “Can You Get A Fever From Morning Sickness?” helps avoid dangerous assumptions about symptom causes during pregnancy.
