Fluctuations and reductions in estrogen are contributing factors in which type of rhinitis?

Vasomotor rhinitis is characterized by nasal congestion, runny nose, and sneezing that are often triggered by non-allergic stimuli such as changes in weather, strong odors, or hormonal fluctuations. In this context, fluctuations and reductions in estrogen can directly contribute to the symptoms associated with vasomotor rhinitis, as estrogen plays a role in the normal function of the nasal mucosa and its reactivity.

During periods of hormonal change, such as menstrual cycles or menopause, women may experience an increase in nasal symptoms due to these hormonal fluctuations. This differentiation is essential in understanding how hormonal interactions can impact allergic and non-allergic rhinitis conditions.

Other types of rhinitis listed do not primarily involve hormonal fluctuations as underlying causes. Rhinitis medicamentosum refers to rhinitis caused by overuse of topical decongestants, while atrophic rhinitis typically involves thinning of the nasal mucosa and is not directly caused by hormonal changes. Viral rhinitis arises from infections, not hormonal factors. Thus, vasomotor rhinitis is specifically impacted by hormonal levels, making it the correct answer.
