After pregnancy, the body’s basal temperature will increase due to the influence of progesterone, and it may be normal for the body temperature to reach 37.4℃, which should be analyzed on a case-by-case basis. First of all, to determine whether 37.4℃ is normal for pregnant women cannot be based solely on one temperature measurement, because the body temperature also fluctuates within 24 hours and is adjusted by biological rhythms. For example, the most common cause of fever is upper respiratory tract infection, so it is important to pay attention to the presence of symptoms such as coughing, coughing and runny nose. For example, the most common cause of fever is upper respiratory tract infection, so it is important to pay attention to the presence of symptoms such as cough, sputum and runny nose. In addition, the body temperature of pregnant women will increase by 0.3-0.5℃ during pregnancy compared to that of non-pregnant women. If a pregnant woman has symptoms such as dizziness, coughing, abdominal pain, diarrhea, etc., she needs to go to the obstetrics or internal medicine department of the hospital to check blood tests to confirm whether there is a bacterial infection, and then treat the fever with symptomatic treatment. Since this is only a low fever and during pregnancy, you can drink more water and at the same time wipe your forehead and armpits with a wet towel to physically cool down the fever without using antipyretic drugs for the time being.
