Pheochromocytoma The Rare Tumor That Causes Extremely High Blood Pressure And Headache

HBP 046- How is High Blood Pressure linked to headaches

Pheochromocytoma is a rare tumor and a rare cause of uncontrolled very high blood pressure. The classic triad of things associated with a pheochromocytoma is episodic headaches, palpitations and sweating. The headaches are typically associated with palpitations, sweating and anxiety. These symptoms, along with the markedly elevated blood pressure are due to hormones / biochemical substances produced by the tumor. The diagnosis is typically made with blood tests.

Blood Pressure: How High Is Too High

Systolic blood pressure is the upper number in a blood pressure measurement. It refers to how much pressure your blood is exerting against your artery walls when your heart beats. The lower number, diastolic pressure, refers to how much pressure your blood is exerting against your artery walls when your heart is resting between beats. A blood pressure of less than 120/80 mm Hg is considered normal.

Nearly half of adults in the U.S. have high blood pressuremeaning greater than 130/80 mm Hgaccording to the American Heart Association . When untreated, high blood pressure increases the risk for heart attack, stroke, and other complications by damaging blood vessels throughout your body.

“In most cases, high blood pressure does not cause headaches, nosebleeds, or any other symptoms,” stresses Salim Virani, MD, professor, sections of cardiology and cardiovascular research, Baylor College of Medicine, Houston.

“If you are waiting for symptoms to tell you that you have high blood pressure, you have missed the boat,” he says. “Waiting for symptoms is actually a very big mistake. We need to pick up high blood pressure in the absence of symptoms.” This gives doctors the best opportunity to treat high blood pressure and avoid complications.

If you have high blood pressure, you have to take your medicine every day, even if you feel fine. Don’t wait for symptoms to take your medication, says Dr. Virani.

Can high blood pressure lead to headaches?

Although most headaches are not serious and will go away on their own, it’s important to recognize when headache pain could be a sign of a larger issue.

Stephen D. Silberstein, MD, director of the Jefferson Headache Center at Thomas Jefferson University in Philadelphia and past president of the American Headache Society, advises: “If your headache is bad, new, or changing, see somebody.”

How Does High Blood Pressure Cause Headaches

Pain levels depend on how high someones blood pressure is. Hypertension headaches may range from mild to severe and are regulated by how much blood is reaching the brain. During times of high blood pressure, blood vessels running through the tissue under the skull constrict or tighten, leading to headache development.

It is also possible for blood pressure medication to cause headaches. Checking blood pressure during headaches can be a good indicator of whether it is caused by abnormal blood pressure levels.

Some medical professionals believe that having a headache due to high blood pressure is a sign of a hypertensive crisis, which is when blood pressure spikes to critical levels.

What Are The Risk Factors For A Thunderclap Headache

People with certain inherited conditions such as weak blood vessels or a tendency to develop blood clots have a higher risk of thunderclap headaches.

Some people with high blood pressure may be more likely to experience thunderclap headaches. These people may be at higher risk of having a blood vessel rupture in the brain.

For some people, activities such as heavy exertion and sexual activity can trigger thunderclap headaches. Once you identify these triggers, avoiding them can help reduce the number of headaches you experience. Your doctor can provide treatment options, including medications, to reduce your likelihood of repeated thunderclap headaches.

  • hydrocephalus, where fluid builds up around and inside your brain
  • abnormal blood vessel, such as an arteriovenous fistula or arteriovenous malformation
  • a blood clot in one of the veins of your brain, known as a venous sinus thrombosis

Rare causes include a blockage in the circulation of fluid at the bottom of the skull , inflammation of the blood vessels in the brain and abnormal skull growth in children .

Can Thunderclap Headaches Be Prevented

Does high blood pressure cause headaches? Myths vs. facts ...

Is Your Headache A Sign Of Something Serious

Most headaches are not serious, but seeking help for those that are could save your life.

Jamie Grill Atlas/Stocksy

Billie, a resident of Asheville, North Carolina, had a history of allergies and headache. One morning she woke up with dizziness, headache, and facial pain.

“I thought it was just my sinuses that hurt, Billie says. But it didn’t get any better, and it was different from the headaches I usually got. My face hurt so much I didn’t even want to brush my teeth. So my husband called the doctor, and he told us to come in right away. Turns out I had giant cell arteritis . If I had waited, the doctor said I might have had a stroke.”

Billie’s story serves as a warning that sometimes a headache is more than just a headache. In fact, a headache can be an early warning sign of more complicated and serious health issues such as stroke, infection, or high blood pressure.

Aura: Warning Sign Of A Migraineand A Future Stroke

Excruciating pain. Nausea. Sensitivity to light. The crushing symptoms of migraine headaches affect 15% of the population and, unfortunately, women are 3 times as likely as men to experience them.

Migraine headaches alone are bad enough. But add the symptoms related to auras and your risk of a future stroke goes up significantly.


A migraine headache with aura, known as a classical migraine, affects up to 30% of migraine sufferers. Five to 20 minutes before the onset of the headache, you see flashing lights, sparks, and dark patches. These effects might be accompanied by the feeling of pins and needles, spreading from one part of your body to another.

In some ways the aura is a good thing. Longtime sufferers recognize the aura as a warning sign of an oncoming migraine. It allows the victim to prepare, taking medication to reduce the severity of the migraine.

The migraine with aura should also be seen as a warning sign of possible stroke and heart problems.


First, the good news: In most people, migraines rarely result in a stroke. Evidence says its also unlikely that a stroke will occur during a migraine.

The not-so-good news: People who suffer migraines are more likely to eventually have some type of heart or vascular problem. A cause-and-effect hasnt been proven. In other words, the migraine with aura doesnt CAUSE the stroke. But the two do occur together.


Hypertension: What Is The Link With Headaches

Hypertension Headache Causing High Blood Pressure | The Cause & The Treatment Solution

Dr. Gaurangi Shah explain, “Hypertension is a serious health condition that accounts to a huge number of heart attacks, paralysis and is also the second leading cause of kidney failure, after diabetes. It is also known as a silent killer as high blood pressure doesn’t show any symptoms. In most cases after severe complications, hypertension is detected.”

“Headache is one of the symptoms of hypertension but is not always. The reason for headache amongst individuals with high blood pressure is a sudden rise in pressure inside the cranium. The headaches due to high blood pressure occur in the occipital region. This pain does not get relived with an analgesic or painkiller. One will need to reduce their blood pressure for the same.”

Headache Caused By High Blood Pressure

Extremely high blood pressure can cause a headache in people with or without diagnosed hypertension.

This type of headache only happens when blood pressure is severely elevated to 180/120 millimeters of mercury or higher, according to the American Heart Association. Normal blood pressure is 120/80 mm Hg.

When blood pressure is extremely elevated, its a medical emergency known as a hypertensive crisis, and medical attention is needed right away.

Migraine And Hypertension Risk

Several studies have identified links between migraine and high blood pressure. One report examined the relationship between women with migraine and hypertension. There were 29,040 women who participated. They did not have hypertension at the onset of the study. They were separated into several categories: active migraine without aura, active migraine with aura, history of migraine, and no history of migraine.

The follow-up, conducted 12.2 years after the study began, showed that of the 29,040 participants, 15,176 experienced incident hypertension. When compared with the women who did not have a history of migraine:

  • Migraine with aura 9% risk increase for hypertension
  • Migraine without aura 21% risk increase for hypertension
  • History of migraine 15% risk increase for hypertension

Anytime that pain is present, it puts stress on the body. Stress, particularly prolonged stress, can cause a persons blood pressure to rise. Pain is one of the hallmark symptoms of migraine and they can last for hours, days, weeks, or even longer. This continual stress can indeed lead to hypertension. Likewise, continual stress, such as what the body endures when blood pressure is elevated, can trigger migraine. It is important to note that hypertension does not necessarily cause migraine, but it is very likely that it can be a trigger.

    What Are Hypertension Headaches

    The pain of these headaches is usually felt on both sides of the head and pulses or throbs. The pain goes away when the persons blood pressure goes down. High blood pressure in these cases means:1

    • A systolic number of 180 mmHg or higher
    • A diastolic number of 120 mmHg or higher

    Lower levels of high blood pressure do not seem to cause headaches. Mid-range high blood pressure may lead to headaches but doctors are not completely sure.1

    Hypertension headaches are known as secondary headaches. This means that the headache is caused by an underlying health condition. A severe headache may be a sign of dangerously high blood pressure.

    High Blood Pressure And Headaches: How To Manage Headaches ...

    At Brisbane Headache & Migraine Clinic, many of our patients have exhausted all of their treatment options, trying to alleviate their hypertensive headaches. Many have altered their blood pressure medications and made changes to their diets with limited success. Some have trialled chiropractor, physiotherapists, massage therapists and osteopaths with no long-term benefit. We aim to assess the upper cervical spine and your brainstem to determine whether they are the true cause of your symptoms.

    Once we have established whether this is the case, then we can start treatment immediately, with expected results in the first 6 sessions, as we see with 85-90% of our patients. Most importantly, our treatment is safe, gentle, medication-free and non-invasive.

    What Causes Hypertension Headache

    The initial thought that hypertension contributes to the distension of blood vessels, causing headache symptoms has yet to be proven in any research. The most current research suggests that sudden rises in blood pressure and severe blood pressure readings are linked to hypertensive headache. In the population of pheochromocytoma patients, 80 % have been linked to episodic headaches .

    The patients that we see at Brisbane Headache & Migraine Clinic often dont present with any of these signs, however they still present with hypertension headache symptoms. In these cases, we assess for dysfunction in the upper cervical spine and sensitivities in the brainstem, to determine whether they may be the true cause. Current research suggests that brainstem hyper-sensitivity in the brainstem, may detect elevations in blood pressure and react abnormally, triggering headache or migraine symptoms.

    Managing Migraines At Home

    Healthy Eating & Living : Does High Blood Pressure Cause Bad Headaches?

    People who have regular, frequent, or unmanageable migraines should getadvice from their doctor. The doctor should check their blood pressure at the same time, to rule out any link with blood pressure that should be treated.

    Some people with migraines may find that they can identify triggers some people get migraines after certain foods, with hormonal changes, with illness, stress, or anxiety. Being able to recognise and manage these triggers, or at least anticipate the possibility of a migraine can help with migraine management.

    Managing a migraine attack is also quite an individual process many people find that being in a darkened room or trying to sleep can help. Taking a dose of a simple painkiller like paracetamol at the very start of the symptoms can help to reduce the overall severity of the migraine.

    If simple home management of migraine isnt working, or theyre frequent and severe enough to have an impact on your day-to-day life, a doctor may consider further investigations or can prescribe stronger treatment for migraine. If nausea and vomiting are a problem, anti-sickness medication can also be prescribed.
