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.
Pixland/ Thinkstock. It's quite common, yet highly annoying -- a runny nose. Your nose drips when your nasal tissues and blood vessels produce excess fluid or mucus, according to the Mayo Clinic. This excess fluid also runs down the back of your throat in the dreaded post-nasal drip. Sometimes you'll have nasal congestion along with your runny nose, but not always. Dozens of things can cause your nose to run, from a variety of allergies and illnesses to more serious conditions like a deviated septum. Certain medications, stress and even pregnancy can also cause a runny nose.
