At the same time, physical deficiency and reduced exercise were reduced.This is why some pregnant women have a cold in the early stages of pregnancy, and they feel that their physical fitness is not as good as before.
2. Frech mucosa change
After women are pregnant, the respiratory mucosa will cause edema and hypertrophy, so it is prone to cold symptoms.
3. The respiratory function changes
At 18 weeks, the oxygen consumption of pregnant women increased by 10-20%(50%of which were consumed by the fetus).The volume of lungs increases by 40%. In order to meet the demand for the pregnant woman and the fetus, pregnant women often excessively breathe.The fetus has no breathing function in the mother. It depends on the mother’s inhalation of oxygen and discharged carbon dioxide. Therefore, pregnant women often feel short of breath and difficulty breathing.Due to excessive ventilation, inhalation of more dust, and the impact of the changes in the mucosa of the respiratory tract, it is easy to cause a cold.
4. The local or respiratory lane local defense function is reduced
Cold, rain, climate mutations, excessive fatigue, etc. reduce the local or respiratory local defense function, so that the bacteria or bacteria that already exist in the upper respiratory tract or invade from the outside world can induce colds.
Symptoms of pregnant women
The cough of expectant mothers is a very painful thing, especially in a special period that was originally frequent urination. It was too embarrassing to accidentally leak urine.In addition, cough will increase abdominal pressure. Therefore, if the cough is too severe and frequent, it may cause abortion or premature birth if the cough is too severe and frequent.
2. Headache and fever
The body temperature of expectant mothers will be slightly higher than ordinary people at about 0.5 ° C. Therefore, if the body temperature rises to 37.5 ° C, you may feel some uncomfortable, such as headache, loss of appetite, fatigue, muscle soreness, etc.
3. Nasal congestion or runny nose
During pregnancy, due to the rise in estrogen levels of expectant mothers, at the same time, the blood capacity in the body also increased a lot, vascular dilation, nasal mucosa is prone to swelling, and the secretions sometimes increased. At this time, if you encounter a cold again,The symptoms of the nasal congestion may feel the heavier than before pregnancy.

3. Avoid staying in a closed space for a long time
After getting up, the room should be opened to exchange fresh air. After work, the office should also pay attention to indoor air circulation.Because the influenza is mainly transmitted through the air droplets through the respiratory tract, disinfection experts point out that ventilation is the best disinfection.In addition, smoking indoors should be avoided in order to retain the fresh space.
4. Reduce large rally activities

Can pregnant women take medicine after a cold?
If the pregnant woman has a serious condition, if the condition is more serious, the medication can be used under the guidance of the doctor. There are three principles for medication during pregnancy: there are three principles:
First, the first 3 months of pregnancy are the sensitive period of fetal development. The tissues and organs of the fetus are in the stage of differentiation and are most likely to be affected by the drug. Therefore, this period should be avoided as much as possible.
Second, no drug is absolutely safe to the fetus. Only when the drug’s benefit to the mother is greater than the danger of the fetus, the medication can be considered;
Third, choose the minimum effective dose and the shortest effective course when using the drug.
If a pregnant woman takes a cold medicine, it has two impact on the fetus: First, the virus directly enters the fetus through the placenta, which may cause congenital heart disease of the fetus, as well as rabbit lips, brain water, brain -free, and small head deformed;The indirect impact of high fever and metabolic disorders caused by colds, high fever and toxins can stimulate uterine contraction, causing abortion and premature birth.So pregnant women can use it as much as possible.
