Can a cold trigger a recurrence of sinusitis?

Generally, a cold may trigger the recurrence of sinusitis. The detailed analysis is as follows:

A cold can lead to the recurrence of sinusitis because it may cause upper respiratory tract inflammation, nasal mucosal damage, blockage of sinus passages, and changes in the immune system. During a cold, viruses may invade the upper respiratory tract, causing mucosal inflammation, including in the nasal mucosa. This leads to narrowing of the sinus passages and obstructs drainage from the sinuses, creating a warm, moist environment favorable for bacterial growth. Frequent sneezing and runny nose during a cold can cause mechanical injury to the nasal mucosa, making it more susceptible to infection. Blocked sinus passages prevent normal drainage of secretions, increasing the risk of bacterial infection. Therefore, a cold not only increases the likelihood of developing sinusitis but may also cause previously existing sinusitis to flare up again.

During a cold, patients may follow medical advice to take antiviral oral solutions, Lianhua Qingwen capsules, Ganmao Ling granules, or similar medications for treatment. At the same time, appropriate care measures should be taken, including ensuring adequate rest and maintaining sufficient fluid intake, to reduce the occurrence and recurrence risk of sinusitis.
