Pregnancy rhinitis is congestion or a stuffy nose during pregnancy. It may feel similar to the nasal congestion you get when you have a cold, but this condition is partly caused by hormonal changes during pregnancy. For example, a higher level of estrogen during pregnancy can cause the lining of the nasal passages to swell, producing more mucus. You also have more blood circulating during pregnancy, which can make the tiny blood vessels inside your nose swell and lead to nasal congestion.
Runny nose results from discharge secreted by the mucous membranes lining the inside of your nose. Allergic reactions are a common cause of runny nose. Such reactions may be caused by pollen (hay fever), animal dander, foods, or medicines.
