Sinusitis is a common condition in Singapore, often triggered by our warm, humid climate and frequent exposure to allergens like dust mites and air pollution.

While many cases resolve with rest and simple remedies, persistent or recurring symptoms may require specialist care.
Sinusitis can cause persistent discomfort, frequent infections, sleep disturbances, and in some cases, even lead to complications if left untreated. Yet, many individuals continue to self-medicate or ignore symptoms altogether—either because they’re unsure of what’s normal, or because they don’t realise there are effective treatment options available.
