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.
Infections â such as colds, influenza or sinusitis â allergies and various irritants, such as tobacco smoke, may all cause a runny nose. Some people have a chronically runny nose for no apparent reason â a condition called nonallergic rhinitis or vasomotor rhinitis (VMR). Less commonly, nasal congestion can be caused by polyps or a tumor. Other potential causes of nasal congestion include: 1  Acute sinusitis. 2  Bright lights. 3  Chronic sinusitis. 4  Churg-Strauss syndrome. 5  Cluster headache. 6  Cold temperature. 7  Common cold.
