what causes fluid in the ear in adults

Fluid in the ear in adults can be caused by various factors, including infections, damage to the ear drum, foreign bodies in the ear, or more serious infections or injuries. The middle ear connects to the throat by a canal called the eustachian tube, which helps equalize the pressure between the outer ear and the inner ear. A cold or allergy can irritate the tube or cause the area around it to swell, preventing fluid from draining from the middle ear. This fluid buildup can lead to bacterial or viral growth, causing a middle-ear infection. Additionally, fluid in the ear can be the result of inflammation, mucous, a growth, or a structural problem in the ear that blocks the drainage of fluid. Its important to see a doctor if you notice any fluid leaking from your ear, especially if you have a fever, hearing loss, dizziness, or if your ear is red and swollen. Treatment for fluid in the ear will depend on the underlying cause and may include keeping the ears dry and avoiding the use of cotton buds or inserting anything into the ears.
