Allergic rhinitis in pregnant women is a challenge for both doctors and patients, who have to consider both the danger of allergic rhinitis to mother and child and the impact of drug treatment on the fetus. I. Allergic rhinitis is very harmful to the mother-to-be 1. Evening nasal congestion affects sleep and long-term nasal congestion appears as a lack of oxygen. It is recommended to supplement the lack of sleep by taking a nap; if necessary, improve the problem of oxygen deficiency by inhaling oxygen. 2. Causes neurological symptoms: Although allergic rhinitis is a “minor problem”, it can cause many “major problems”. The nasal cavity is connected to the pharyngeal cavity, the inflammation of the nasal cavity, involving the pharyngeal cavity, easy to cause pharyngitis, down can involve the larynx, bronchial tubes, laryngitis and even asthma; inflammation spread upward, can also cause eye disease and otitis media. If left untreated, it can also cause sinusitis, nasal polyps, leading to dizziness, headaches, dreaminess, memory loss, neurological weakness, etc., which seriously affects the quality of life of pregnant mothers. 3. Severe sneezing during an attack of rhinitis increases the abdominal pressure of the mother-to-be, which can easily lead to miscarriage or premature birth of the fetus. If allergic rhinitis strikes, the mother-to-be should weigh the possible effects of the condition on the fetus and the efficacy of the medication when treating it, and use it carefully on the balance of pros and cons. Allergic rhinitis treatment for pregnant women is the most important way to detect and avoid allergens, which can improve the mother’s quality of life and minimize the use of medications. The most important symptom of allergic rhinitis during pregnancy is nasal congestion, appropriate physical exercise to reduce nasal congestion, the use of head high feet low position is also effective, the head of the bed can be padded 15-30 degrees (brick pad foot), which is more tolerable than adding pillows. 3, nasal saline rinse or seawater spray can relieve symptoms, because this can remove allergens and reduce secretions and dry crusts. 4.Doing nasal health exercises to massage Ying Xiang and other acupuncture points can also relieve symptoms. 5.For severe symptoms, appropriate medication is needed to control allergy symptoms. However, drugs may cause malformations in fetal development through the placenta, and the drugs currently in common use often lack data on safety during pregnancy. Therefore, the possible effects of the drug on the fetus should be adequately weighed (Table 1). Desensitization therapy should not be initiated during pregnancy, and pregnant women undergoing desensitization without systemic reactions may continue desensitization but not increase the dose.
