Explained: Why even a mild fever during pregnancy should not be ignored

New Delhi: Pregnancy is a unique and transformative journey, but it also brings significant changes to a woman’s body. One of the most important changes occurs in the immune system. To protect the growing baby, the immune response becomes altered, making expectant mothers more vulnerable to infections. Because of this increased sensitivity, even a mild fever during pregnancy should never be ignored.

In an interaction with News9Live, Dr. Tripti Raheja, Director – Obstetrics & Gynaecology at the CK Birla Hospital, Delhi, spoke about mild fever during pregnancy and what it entails.

Fever itself is not a disease; it is the body’s natural response to fighting an infection. In non-pregnant individuals, a low-grade fever may resolve on its own without causing harm. However, during pregnancy, even a slight rise in body temperature can be a warning sign that requires medical attention. Ignoring fever may delay diagnosis of an underlying infection, which can pose risks to both the mother and the baby.

In the early stages of pregnancy, particularly during the first trimester, the baby’s organs and nervous system are rapidly developing. High or prolonged body temperature during this critical period may interfere with normal fetal development. While a brief, mild fever may not always cause harm, persistent fever should be evaluated promptly to rule out serious infections and prevent complications.

During the later months of pregnancy, untreated infections can have different but equally serious consequences. Fever may lead to dehydration, weakness, reduced appetite, and increased stress on the body. In some cases, infections can trigger early uterine contractions, increasing the risk of preterm labor. Babies may also experience distress if the mother’s infection is not treated in time. Often, it is not the fever itself but the infection behind it that causes these complications.

Seasonal illnesses further increase the importance of caution. Influenza is a common viral infection that can be more severe during pregnancy, causing extreme fatigue, breathlessness, and prolonged recovery. Pregnant women are also more susceptible to mosquito-borne infections such as dengue and malaria, especially during the monsoon season. These infections can lead to high fever, intense body pain, weakness, and low platelet counts, making close monitoring and timely treatment essential.

It is also important to avoid self-medication during pregnancy. Many common fever-reducing medicines may not be safe for expectant mothers. Seeking medical advice ensures that both the cause of the fever and the treatment are appropriate and safe.

In pregnancy, fever should always be taken seriously. Early evaluation, accurate diagnosis, and timely treatment help protect maternal health and support healthy fetal development. Paying attention to even mild symptoms can make a significant difference in ensuring a safe and healthy pregnancy for both mother and baby.
