What Is Sinus Drainage?
Sinus drainage is the process by which mucus flows naturally from the sinuses into the nasal passages. Healthy drainage helps clear allergens, bacteria, and debris from the sinuses. When this process is disrupted due to allergies, inflammation, or structural issues, there is excess mucus build up leading to congestion, sinus pressure, and frequent infections.
Common Causes:
● Sinus Infections (Sinusitis): Inflammation from bacterial, viral, or fungal infections can cause mucus buildup.
● Allergies: They can trigger inflammation leading to increased mucus production and congestion
● Nasal Polyps: Mucosal tissue can block sinus drainage and invade all the sinus cavities leading to poor smell and taste.
● Chronic Inflammation: Persistent irritation from smoke, pollution, or other environmental factors can lead to mucosal irritation
