A blocked or stuffy nose is a very common, albeit frustrating, symptom of pregnancy, affecting approximately 20% to 30% of expectant mothers. Often referred to as "pregnancy rhinitis" or "pregnancy nose," this congestion is a result of the immense hormonal and physiological changes your body undergoes to support a developing baby. While rarely dangerous to the baby, it can significantly impact your sleep, comfort, and daily life. Here is a helpful guide to understanding and managing a congested nose during pregnancy. What Causes Pregnancy Rhinitis? Hormonal Changes: Elevated levels of estrogen and progesterone increase blood flow throughout the body, including to the mucous membranes in your nose, causing them to swell.
