Nasal congestion may be caused by acute rhinitis, chronic simple rhinitis, allergic rhinitis, or drug-induced rhinitis. It can also result from deviated nasal septum, hypertrophied inferior turbinates, nasal foreign bodies, nasal masses, or tumors. Additionally, other factors such as lifestyle, environmental influences, and medications cannot be ruled out as potential causes.
