Caffeine and Tinnitus……Is It Possible There Is No Connection?

One of the world’s most international experiences is coffee, but so is tinnitus…..

It is truly an international beverage from far away places, roasted, brewed, squeezed, pressed, boiled, perked and has each country has their culture in every cup. Products are invented over coffee, research projects are generated and, in Turkey, fortunes are told by coffee grounds. Coffee is enjoyed with shisha pipes in smoked filled coffee houses in the Middle East, espresso coffee shops and white table clothed restaurants in Europe, and the vehicle cup holders in America.

Howard Shultz learned that coffee was a culture long before most Americans when he traveled to Italy and became captivated with Italian coffee bars and the romance of the European coffee experience. Shultz had a vision to bring the Italian coffeehouse tradition back to the United States and offer the coffee house as a place for conversation and a sense of community.  Of course, this spurred the rise of Starbucks from a small, one-store Seattle operation in 1971, to an international operation with over 15,000 stores (or coffee houses) in 50 countries.

In Europe, most people do not “grab” coffee at a drive up and slurp it as we do in America but they linger and interact with others over a tiny cup of espresso– a different culture, but coffee and caffeine just the same.  That best remembered cup of coffee is like an old girlfriend/boyfriend that you will always hold in a special place.  Personally, I remember the most expensive cup ever one evening while exploring Venice with Swiss friends.  The cup was served in San Marco Square, on a beautiful summer evening with an orchestra playing Beethoven.   At 80 Euros for 4 coffees, the cup was very special, as was the Grappa that came with it, but the frendship and the memories were priceless.

No matter how great the memories, coffee and many teas are loaded with caffeine which has for many years been tied to tinnitus.

As I traveled to various parts of the world, one of the first questions I would be asked by audiologists and physicians was, “What do you do for tinnitus in America?”. In the Audiological world, tinnitus often accompanys various types of hearing impairment and is a common complaint, in varying degrees of most hearing impaired patients.  Of course, for most of my career (and probably yours as well) one the first questions on the Case History form for tinnitus is about caffeine intake.    Harding (2010) echos what Audiologists and Otolaryngologists have thought for a very long time, that kicking caffeine can assist to ease ringing in the ears. In fact, physicians and audiologists often recommend caffeine restriction for patients with tinnitus, despite the lack of scientific evidence of any benefit for this recommendation. DuPriest (2011) supports the age old recommendation to reduce caffeine intake, suggesting that caffeine is a well-known vasoconstrictor of blood flow in the brain and a vasodilator in the muscles. In doses above 250 mg per day caffeine is known to constrict blood flow in the brain, and can cause irritability, jitters, insomnia, heart palpitations, stomach upset, and headaches. Researchers also suggest that caffeine consumption is so common world wide, and its vasoconstriction effect on the brain so predictable that its use probably confounds the results of MRIs and other brain scans as well as cerebral blood flow in brain scans of people going through caffeine withdrawal.  As a general rule of thumb, Aubrey (2006) most caffeine users need a surprisingly small amount of the stimulant to enjoy its pleasant effects. Studies show that 100 milligrams — just a 6-ounce cup of a typical automatic-drip coffee — produces a lift…Now translate that to a Venti-sized Starbucks (20 oz.)…..Hmmm, thats about 320 milligrams in one cup!  Espresso is a bit less as there is less in the cup, 1.5 oz about 77mg of caffeine.

A relatively new study at the University of Bristol in the UK by St.Claire et al (2010) is now offering evidence that caffeine may not be a major player in tinnitus.  Although vasoconstriction and all the other symptoms make sense to the seasoned professional, their study did not confirm a connection.  The St. Claire et al study followed a group of subjects over a 30-day period. Half of the participants kept up their normal caffeine consumption and then went through a “phased withdrawal” in which the researchers gradually reduced the caffeine content of the beverages consumed by participants. The other half of the group went through phased withdrawal first and then resumed to their normal intake.  Study participants didn’t know which group they were in. St. Claire and her team purposely made withdrawal relatively gradual to ensure that neither group suffered severe withdrawal symptoms. But the phased withdrawal also prevented participants from identifying which group they’d been assigned to based on their symptoms.

The researchers found that the amount of caffeine a person consumed had no effect on the severity of tinnitus. But people did experience significant caffeine withdrawal symptoms, including headache and nausea.

 “There was no way it appeared worth their while to go through caffeine withdrawal, because there was no improvement in their tinnitus,” St. Claire said.

Although this will probably not get most of us to take the caffeine questions off of our case history forms, the research is interesting and offers a possible insight into caffeine intake, perhaps allowing us to keep our coffee in the morning.

  1. Bob,
    This has been one of the more intersting articles and perspectives that I’ve read lately, especially discussing direct the relationship between coffee and tinnitus. Well done! I have been assessing and treating tinnitus in our practice and found the study from The University of Bristol quite good!
    Thank you!
