Nasal congestion due to colds and dyspnea may be caused by congestion and edema of nasal mucosa caused by colds. If the symptoms are not serious, it is better for pregnant women not to take medicine internally, but to breathe with their mouth temporarily. During this period, they should have more rest and drink more warm water to promote excretion. They can use hot water to compress both sides of the nose, which can alleviate the symptoms of nasal congestion. When sleeping, they sleep on their side, and most of them will recover quickly. If the nasal congestion is serious during pregnancy, nasal drops can be used locally to relieve congestion and edema of nasal mucosa, improve the symptoms of stuffy nose, and it is prohibited to purchase drugs for treatment.
