Tinnitus

What Is It?

Tinnitus, commonly called ringing in the ears, is the sensation of hearing a sound in the ears when no such sound exists. This sound, which originates inside the head, typically is described as a ringing, but it also can take the form of an annoying hiss, whistle or buzz. Tinnitus can be constant or can come and go.

Most often, tinnitus is a symptom of an ear problem, such as earwax buildup, age-related hearing loss, Ménière's disease, inner-ear damage from loud noise, or middle-ear damage caused by a sudden change in pressure (barotrauma). Occasionally, tinnitus develops as a side effect of medication. Aspirin in moderate to high doses often causes tinnitus.

Health experts estimate that more than 30 million people in the United States have some form of tinnitus.

Symptoms

Tinnitus is a symptom in itself. However, people who have tinnitus also may have the following:

• Insomnia
• Difficulty concentrating
• Depression
• Frustration
• Irritability

In addition, depending on the cause of tinnitus, there also may be:

• Hearing loss
• Dizziness or vertigo
• Pain or a plugged feeling in the ear
• Nausea

Diagnosis

The cause of tinnitus may be difficult to determine. Your doctor will ask if you have been exposed to loud noise at work or home, and will ask about medications you take, including all herbs and supplements. He or she may look in your ears to see if you have wax blockage or if the eardrum appears abnormal. If your hearing is affected, then your doctor may have you undergo a hearing test called an audiogram to measure your hearing ability in each ear.

Expected Duration

Nearly everyone experiences a few brief episodes of ringing in the ears at some point in life, and in most cases these brief occurrences pass without medical treatment. However, in some people with tinnitus, the problem is a persistent source of discomfort.

Prevention

The best way to prevent tinnitus is to avoid loud noises. Wear earplugs or ear muffs when working around loud equipment, such as chain saws, lawn mowers, and high-speed power tools.

If you have persistent tinnitus, review your list of medications with your doctor or pharmacist to see if any may be contributing. Some people find that they can lessen the intensity of tinnitus by limiting caffeine.
