Pregnancy in asthma can be taken care of by avoiding asthma-promoting factors and medication. Eliminate and avoid, as much as possible, exposure to various allergens in the environment, such as dust, soot smell, pollen, spices, cold air and pets. Prohibit smoking, as well as avoid passive smoking in pregnant women. In case of oxygen deprivation, administer oxygen promptly to ensure adequate oxygen supply to the pregnant woman and the fetus. The first trimester of pregnancy is a critical period for fetal development, and medication should be administered strictly, using non-pharmacological therapies whenever possible. After the third trimester, the use of drugs can be appropriately relaxed. Try to avoid the use of drugs whose safety for the pregnant woman and the fetus has not been established. During pregnancy, it is necessary to monitor the physiological status of the pregnant woman and her fetus, and to detect changes in their condition at an early stage. In case of abnormality, it is recommended to seek timely medical attention, follow the doctor’s instructions for relevant examinations, clarify the causes with the help of the doctor, and carry out targeted treatment or therapy.
