The sensation of clogged ears can be caused by several common factors:
- Eustachian tube dysfunction (ETD): The Eustachian tubes connect the middle ear to the throat and help equalize pressure. When these tubes become blocked or do not open properly, fluid or mucus can get trapped in the middle ear, causing a clogged feeling. This often occurs with infections (colds, flu, sinusitis), allergies, or altitude changes such as flying or driving in mountains.
- Earwax buildup: Excessive or hardened earwax can block the ear canal, producing a clogged sensation, muffled hearing, or discomfort. Using cotton swabs improperly can worsen this by pushing wax deeper.
- Ear infections: Infections in the outer ear (e.g., swimmer’s ear) or middle ear can cause inflammation, fluid buildup, and pressure that feel like clogging.
- Pressure changes: Rapid altitude changes impact the Eustachian tube's ability to equalize pressure, leading to temporary clogged ears, common in airplane travel or scuba diving.
- Other causes: Less commonly, abnormal growths like cholesteatoma can also cause a sense of ear blockage.
If ears feel clogged, swallowing, yawning, or chewing gum may help open the Eustachian tubes and relieve pressure. Persistent clogged ears, especially with pain or hearing loss, should be evaluated by a healthcare professional.
In summary, clogged ears usually result from blocked Eustachian tubes, earwax buildup, infections, or pressure changes affecting the ear's ability to drain fluid and equalize pressure properly.
