Your nose constantly produces mucus to keep itself moist and healthy. However, excessive mucus production can be caused by several factors.
Common Causes of Excess Mucus
- Allergies: When your immune system overreacts to harmless substances like pollen, dust, or pet dander, it releases histamine. This causes nasal membranes to swell and mucus glands to produce more mucus. [Source: NIH News in Health, Banner Health]
- Infections: Viral and bacterial infections stimulate your nose and sinuses to produce extra mucus to flush out the invading pathogens. [Source: Healthline, Cleveland Clinic]
- Irritants: Cold, dry air irritates your nasal lining, prompting your glands to produce excess mucus to maintain moisture. [Source: NM Healthbeat]
- Nasal Polyps: These benign growths in your nasal passages can block mucus flow, leading to increased production. [Source: Johns Hopkins Medicine]
- Postnasal Drip: Excess mucus from the sinuses drains down the back of your throat, often leading to a feeling of extra mucus in the nose and throat. [Source: WebMD]
Understanding Normal Mucus Production
Your body naturally produces mucus to trap dust, pollen, and other irritants. Normally, this mucus is clear or slightly white. Changes in color, consistency, or amount can indicate an underlying condition. [Source: Temple Health]
When to See a Doctor
While occasional excess mucus is common, persistent or unusually thick, colored mucus warrants a doctor's visit. They can determine the underlying cause and recommend appropriate treatment. [Source: Cleveland Clinic]
