The Impact of Pregnancy Associated Hormonal Changes on Sinusitis and Rhinitis: A Narrative Review

Background: Hormonal changes during pregnancy significantly affect various physiological systems, including the respiratory tract, contributing to the onset and progression of sinusitis and rhinitis. These conditions can impact the quality of life of pregnant women and pose potential risks to maternal and fetal health. Aim: To explore the prevalence, risk factors, pathophysiology, clinical manifestations, diagnostic challenges, and management strategies for sinusitis and rhinitis during pregnancy, emphasizing the role of hormonal fluctuations. Methods: A narrative review was conducted by analyzing and synthesizing data from relevant studies, focusing on the impact of pregnancy-related hormonal changes on the nasal and sinus mucosa. Peer-reviewed articles published in reputable medical journals were reviewed, emphasizing prevalence, pathophysiology, clinical challenges, and treatment options. Results: Pregnancy-associated rhinitis affects approximately 10% of pregnant women, with nasal obstruction, rhinorrhea, and sneezing being common symptoms. Elevated estrogen and progesterone levels contribute to increased vascular permeability, mucosal edema, and immune modulation, predisposing women to sinus inflammation and infection. These hormonal changes complicate the differentiation between physiological nasal changes and pathological conditions, creating diagnostic and management challenges. Most cases are mild, but complications such as obstructive sleep apnea and adverse fetal outcomes have been reported. Conclusions: Hormonal fluctuations during pregnancy play a pivotal role in the development and progression of sinusitis and rhinitis. Management strategies focus on conservative approaches, such as saline nasal sprays and humidification, to ensure safety for both mother and fetus. Pharmacological interventions are considered only when necessary and must have established safety profiles. Further research is needed to understand long-term outcomes and optimize treatment approaches for these conditions.
