Coughing during pregnancy is usually not significantly associated with fetal gas because it may be caused by respiratory infections, allergies, mental factors, etc. Long-term coughing can increase abdominal pressure and stimulate the uterus, which may lead to miscarriage or induce preterm labor. Therefore, when a pregnant woman develops a cough, she should promptly identify the specific cause and carry out symptomatic treatment under the guidance of a professional doctor to prevent it from affecting the development of the fetus.1. Respiratory infections: During pregnancy, a woman’s resistance decreases and she is susceptible to infections such as viruses and bacteria, which can cause respiratory infections such as colds and bronchitis, resulting in coughing symptoms. If the symptoms are mild, they can be relieved by drinking more water and resting more often, eating a light diet and keeping the room ventilated. If the symptoms are severe, symptomatic treatment can be carried out under the guidance of a doctor. If the infection is caused by bacteria, it can be treated with antibacterial drugs, but drugs that have less impact on the fetus, such as amoxicillin, should be used. 2. Allergic cough: If a pregnant woman comes into contact with allergens such as dust mites, pollen, cold air, etc., it is also easy to induce an allergic reaction in the respiratory tract and cough symptoms. Pregnant women need to go to the hospital for allergen testing in a timely manner, and then treat the symptoms under the advice of a professional doctor. Avoid contact with allergens to prevent aggravation of the cough. Recently, it is necessary to minimize outdoor activities and take more rest. 3. Mental factors: When pregnant women are overly nervous or have excessive mood swings, cough can be triggered by affecting the neural reflexes of the brain or by hyperventilation. Pregnant women need to maintain a calm state of mind and can release stress by listening to soothing music and doing yoga.
