Early Pregnancy And Stuffy Nose

A stuffy nose in early pregnancy is often called . It is a common symptom, affecting roughly 20-30% of expectant mothers. It is primarily caused by hormonal shifts—specifically rising estrogen and progesterone—that increase blood flow and cause the nasal passages to swell.

The paper would likely find a spike in congestion symptoms between weeks 7 and 10, correlating with the peak of the corpus luteum’s hormone production before the placenta fully takes over. early pregnancy and stuffy nose

Background: Nasal congestion is one of the most frequently reported yet under-researched symptoms of the first trimester. Often dismissed as a trivial nuisance, early pregnancy rhinitis can significantly impact sleep quality, daytime fatigue, and quality of life (QoL). Furthermore, the overlap with infectious rhinosinusitis often leads to misdiagnosis and unnecessary medication. Objective: To characterize the prevalence and severity of nasal congestion in the first trimester, identify distinct hormonal and vascular correlates, and evaluate the efficacy of non-pharmacological interventions. Methods: A prospective cohort study of 400 pregnant individuals recruited at <6 weeks gestation. Participants completed the Sino-Nasal Outcome Test-22 (SNOT-22) bi-weekly. A subset underwent acoustic rhinometry to measure nasal patency and blood hormone correlation (Estrogen, Progesterone, hCG). Results: (Hypothesized) Data indicates a significant increase in nasal resistance correlating with rising estradiol levels as early as week 6. 65% of participants reported moderate-to-severe congestion. The study highlights a strong correlation between congestion severity and reported insomnia/obstructive sleep apnea symptoms. Conclusion: Early pregnancy rhinitis is a distinct clinical entity driven by hormonal vasodilation. Early screening using SNOT-22 and proactive saline management can improve maternal sleep hygiene and reduce the risk of gestational hypertension associated with poor sleep.
