“There is no evidence that high blood pressure alone can cause tinnitus,” says William Manger, MD, PhD, founder of the National Hypertension Association, professor emeritus at the New York School of Medicine, and author of the book, “Live Longer, Live Better: Avoid the Risks.”

Be very careful about how you interpret other websites listing “high blood pressure” as a “cause” of tinnitus.

A direct cause of a symptom is not the same as an agent that makes a pre-existing symptom more noticeable or worse.

On the mayoclinic.com site for tinnitus, under the main header of “Causes,” there is a sub-header titled “Blood vessel disorders linked to tinnitus.”

The term “linked” does not mean causative.

The site further explains as follows: Hypertension and factors that increase blood pressure, such as stress, alcohol and caffeine, can make tinnitus more noticeable.

Thus, while high blood pressure is not a direct cause of tinnitus, it can make you notice it more.

Tinnitus, which is very common, is a symptom, not a disease. “Tinnitus is usually associated with a loss of hearing caused by a variety of conditions,” says Dr. Manger.

The American Tinnitus Association lists the following “catalysts” of tinnitus:

• Hearing loss from age

• Exposure to loud noise

• Excessive earwax

• Loose hair from the ear canal

• Head or nasal congestion

• Foreign objects or dirt in the ear

• Head or neck trauma

• TMJ disorder (benign condition affecting the jaw joint)

• Side effects of some drugs

• Meniere’s disease (inner ear disorder)

Brain tumor

You may learn that you have high blood pressure at about the same time that you develop tinnitus or notice some kind of ongoing hissing or very high frequency tone in your ears.

This establishes duality of conditions, not cause and effect.

Dr. Manger, who began practicing medicine in 1949, has conducted research on the mechanism of salt-induced hypertension, and has published research in peer-reviewed journals.
