4 Common Pulsatile Tinnitus Causes
Pulsatile tinnitus is a form of tinnitus where instead of a random noise; the sufferer hears a rhythmic sound in
beat with their heartbeat. Pulsatile tinnitus causes are fewer than other types of tinnitus and it easy to
distinguish between the two – the sound will be in rhythm with the feel of the pulse.
There is more chance of discovering the cause of pulsatile tinnitus than for non-pulsatile tinnitus, so if you
are suffering from a rhythmic sound that matches your pulse, tell your doctor as soon as possible.
The causes of pulsatile tinnitus are rarely severe, but because they are often easier to find they hold more
chance of possible cure, although not all pulsatile tinnitus have a cause. It is normally attributed to increased
blood flow, and is often heard after exercise by many people, only occasionally does this sensation stay after the
heart rate has slowed.
One more serious cause is severe anemia. Anemia is a condition where there is a reduction in red blood cells in
the body; this can be caused by low iron, vitamin b12 deficiency (pernicious anemia), infection, cancer, or kidney
If anemia is detected during a blood test, then it is important to discover the cause of the anemia, especially
anemia severe enough to cause pulsatile tinnitus. Other symptoms should be present, such as fatigue, bleeding gums
and easy bruising.
Once the cause of the anemia has been discovered then it can treated and the pulsatile tinnitus should go away
on its own.
Blood flow increases during pregnancy, and this can lead to the perceived pulsatile tinnitus, although it can be
quite distressing for the sufferer, this is little to worry about as after birth the problem will likely right
Simply this means the arteries and blood vessels to narrow and harden, decreasing the smooth blood flow, making
it harder for the blood to flow. This can cause the blood to flow ‘noisily’ over the blood vessels, causing the
The same way as plaque accumulates on your teeth over time, so it accumulates in your body. This happens with
age and with an unhealthy lifestyle, and can cause problem with your heart and lungs. If your doctor thinks this is
causing the problem, they will recommend lifestyle changes in order to prevent further health problems.
Hyperthyroidism simply means your thyroid is overactive and producing too much thyroid hormone, this can cause
all sorts of symptoms like weight loss, racing heart, palpitations, muscle wasting, fatigue and hair
Because of the racing heart, the blood flows faster and this can cause pulsatile tinnitus, but it shouldn’t be
the only symptom. A thorough medical history should point towards thyroid problems and these can be treated with
drugs that suppress the thyroid hormone, but not the thyroid.
Hyperthyroidism is easily detected with blood tests, and your doctor should be able to decide whether such tests
Pulsatile tinnitus often has a more definitive cause than other forms of tinnitus, because of this it is often
easier to diagnose and treat, but not always. If your doctor is unable to find a cause for your tinnitus then it is
unlikely to be anything serious.
