Fluid in Ears Causes
The ear is one of the sensory organs. It not only helps in hearing but also aids in maintaining balance of the body. An ear is divided into three parts – inner ear, middle ear and outer ear. Usually, fluid accumulation is observed in middle ear. It is filled up with air but because of some reasons air may be replaced by fluid. The inner ear can also experience this but it is a rare condition. Generally, fluid drains on its own from Eustachian tube to throat backside, but sometimes it may get trapped and gives rise to several problems. Thus, it is must to know fluid in ears causes to avoid severe complications. Read through the below lines to know more about the causes of fluid in ears.
Fluid in Ears Causes:
Fluid in ear may be accumulated due to various reasons. In the middle ear, mucus gets accumulated. The accumulated fluid can cause several fungal, bacterial and viral infections. In severe cases, these can cause hearing loss. Here is a list of a few causes of fluid in ears that help one to avoid such situations and to get them treated as early as possible.
Swimmer’s ears: Usually this condition is seen in swimmers, hence the name. It is also called otitis externa and forms in ear canal. If contaminated and dirty water remain in the ear for a prolonged time, it can cause bacterial infection. In contaminated water, pseudomonas aeruginosa bacteria flourish well. If this water gets trapped in ear, one can suffer infections. These infections further cause itching, swelling, pus formation, redness and pain.
Infections: Infections like throat infection, cold or sinus can block Eustachian tube. This tube aids in draining out fluid which enters ear canal. This can trap fluid in middle ear that gives perfect environment for bacteria and viruses to grow. Bacteria like Haemophilus influenza and streptococcus pneumonia and viruses like influenza virus and respiratory syncytial virus are some causes of ear infections.
Eustachian Tube Dysfunction: The Eustachian tube is underdeveloped in infants and children. Hence, it is small and has a very small curvature. This causes fluid in ear that result in ear infections. As you grow older, the Eustachian tube develops and thus, prevents fluid accumulation in ear canal. This can be observed in some adults whose Eustachian tube is underdeveloped.
Allergies: This also causes fluid in ear. Sinus and nasal allergies can cause swelling in tissues at the opening of Eustachian tube. This leads to blockage and water may get trapped in the middle ear. Thus, microorganisms spread colonies resulting in several infections.
