Why do I have a fever during pregnancy? Revealing the causes and countermeasures of increased body temperature during pregnancy
During pregnancy, many expectant mothers will find that their body temperature is slightly higher than usual, and they may even have a low-grade fever. Is this a normal physiological reaction or a potential health problem? This article combines hot topics and data analysis on the Internet in the past 10 days to provide you with a detailed explanation of the causes, common symptoms and scientific responses to fever during pregnancy.
1. Popularity list of pregnancy health topics in the past 10 days across the entire network
| Ranking | Topic keywords | Search volume (10,000) | Main discussion platform |
|---|---|---|---|
| 1 | Fever in early pregnancy | 28.5 | Xiaohongshu/Zhihu |
| 2 | Body temperature changes during pregnancy | 19.2 | Baby Tree/Meiyou |

| 4 | Pregnant woman with cold and fever | 12.3 | Baidu knows |
| 5 | immune system during pregnancy | 9.8 | Medical Forum |
2. Three main causes of increased body temperature after pregnancy
1.progesterone effect: After the fertilized egg implants, the progesterone level increases significantly, which directly affects the body temperature regulation center and increases the basal body temperature by 0.3-0.5°C. This is the most common physiological increase in body temperature.
2.Immune system adjustments: In order to protect the fetus from being rejected by the mother, the immune function of pregnant women will naturally decrease, resulting in a temporary weakening of the resistance to pathogens and an increased risk of infection.
3.Increased metabolic rate: After pregnancy, the basal metabolic rate increases by 20%-25%, and the increase in energy consumption will produce more heat, especially in the second and third trimesters of pregnancy.
3. Criteria for Distinguishing Physiological Fever and Pathological Fever
| Features | Physiological fever | Pathological fever |
|---|---|---|
| body temperature range | 37.2-37.8℃ | >38℃ |
| duration | Sustained stability | Fluctuations are obvious |
| accompanying symptoms | No special discomfort | Headache/chills/fatigue |
| Pregnancy characteristics | Obvious in early pregnancy | possible at any time |
4. Countermeasures suggested by experts
1.daily monitoring: It is recommended that pregnant women measure their body temperature at a fixed time every day and establish a body temperature change curve. The best time to measure is in the morning when you are inactive.
2.physical cooling: When the body temperature exceeds 38℃, you can cool down by taking a warm water bath (avoiding the abdomen), drinking more warm water, and keeping the environment well ventilated.
3.Principles of drug use: If the body temperature exceeds 38.5℃, you need to seek medical treatment. Salicylic acid drugs such as aspirin are prohibited. Acetaminophen must be used under the guidance of a doctor.
4.nutritional support: Increase the intake of vitamin C (200mg/day) and zinc (15mg/day), and supplement appropriate amounts of probiotics to maintain intestinal immunity.
5. Warning signs that require immediate medical attention
• Body temperature continues to exceed 39°C for more than 2 hours
• Have regular uterine contractions or vaginal bleeding
• Confusion or severe headache
• Significant decrease in urine output (<500ml/day)
• Abnormal fetal movement decreases or disappears
According to the latest medical research data, about 65% of pregnant women will experience a physiological increase in body temperature in the first trimester, of which only 12% are eventually diagnosed as pathological fever. Expectant mothers do not need to be overly anxious, but they should also maintain scientific knowledge and monitor their health.
Body temperature changes during pregnancy are important signals sent by the body. Understanding the physiological mechanisms and mastering the correct response methods can not only ensure the safety of mother and baby, but also avoid unnecessary medical intervention. It is recommended that every expectant mother establish a personal health file and record body temperature trends in detail to provide an important reference for prenatal check-ups.
