Nasal polyps may disappear on their own, but overall, this possibility is very small. If the nasal polyps are particularly small and localized, in the early stages of the disease, they may shrink on their own if the body's immune response is strong and the nasal cavity maintains normal ventilation and drainage. However, overall, the likelihood of spontaneous regression is very low. Most nasal polyps, without timely treatment and intervention, tend to gradually increase in size, and can easily cause nasal congestion, runny nose, reduced sense of smell, and may even trigger sinusitis, leading to headaches, dizziness, and thick nasal discharge. Therefore, it is recommended to visit an otolaryngologist (ENT specialist) for a formal assessment and timely treatment after discovering nasal polyps, and then observe the effects.
