If a pregnant woman has a cough with phlegm, she can drink more water, which is good for the dilution of phlegm and can promote the discharge of phlegm. The usual diet should be light, with less spicy and oily food and sweets, and avoid fish, shrimp and seafood. A combination of Chinese and Western treatments can improve the efficiency of treatment. If the cough is caused by wind-cold, you can take a decoction of 10g of ginger, 10g of white onion, 15g of peel and 10g of lily with water as a tea substitute, which has the effect of dispersing cold and relieving cough and phlegm. You can also use the Chinese herbal soup Sanjiao Tang combined with Stop Cough San to reduce the effect of dispersing wind and cold, promoting the lung and relieving cough. If the cough is caused by wind-heat, you can use Sang Ju Drink plus or minus, which has the effect of dispersing wind and clearing heat, promoting the lung and relieving cough. If the above treatment is not effective, it can be combined with antibiotic drugs to control the infection in the lung, such as penicillins and cephalosporins. When choosing medication in general, you should choose drugs that have no effect on the fetus and pregnant women.
