Nosebleeds: A Warning Sign Of Stroke?

While nosebleeds are usually isolated incidents that stop on their own, they can sometimes be a sign of a more serious underlying health issue. For example, a rare genetic disorder called Hereditary Hemorrhagic Telangiectasia (HHT) can cause severe nosebleeds as well as abnormal blood vessels in other parts of the body. In some cases, HHT can lead to an ischemic stroke caused by a blocked blood vessel in the brain. Additionally, chronic hypertension, a leading risk factor for strokes, can also cause recurring nosebleeds. However, it is important to note that nosebleeds are almost never a primary stroke and can often be managed by holding pressure on the nose or with medical intervention.

Nosebleeds are almost never a primary stroke

Nosebleeds are usually isolated incidents that stop on their own and are not a sign of a stroke. However, for about 15% of people, nosebleeds are a regular occurrence. While this can often be managed by holding pressure on the nose, in some cases, medical or surgical intervention is necessary.

Nosebleeds typically originate from the area at the front of the nasal septum known as Kiesselbach's plexus, where several arterial branches converge. The vessels ensure a good blood supply to the sinuses, but they can also cause frequent nosebleeds. In adults, turbulent airflow can lead to nosebleeds, especially in the case of a deviated nasal septum. Cold, dry air can also be a trigger.

Individuals who take aspirin to prevent heart attacks or have a platelet condition that impairs their ability to form blood clots are also more likely to experience recurrent nosebleeds. According to Dr. David A. Gudis, associate professor of otolaryngology/head & neck surgery at Columbia University, "It's easier for us to manage nosebleeds than to manage a stroke or a heart attack, so I would rather treat their nosebleeds aggressively so that patients can stay on their anticoagulant or antiplatelet medications."

While nosebleeds are almost never a primary stroke, they can be a symptom of other serious health issues. For example, hereditary hemorrhagic telangiectasia (HHT) is a rare genetic condition that can cause abnormal blood vessel formation and severe nosebleeds. HHT can lead to ischemic strokes, brain abscesses, or bleeding into the brain or lungs. Therefore, if nosebleeds are frequent or interfering with daily activities, it is important to see a specialist to determine the underlying cause.

Recurrent nosebleeds can be indicative of a more significant health issue

One such problem is hereditary hemorrhagic telangiectasia (HHT), a rare genetic disorder that causes abnormal blood vessel formation. HHT is often misdiagnosed and not well understood by physicians. The most common symptom of HHT is severe and recurrent nosebleeds, but the condition also causes abnormal blood vessels in other parts of the body. Even without a family history, spontaneous mutations can cause HHT, so it is a diagnosis that should be considered for patients with frequent or recurrent nosebleeds.

Another potential cause of recurrent nosebleeds is the use of antiplatelet or anticoagulant medications, such as aspirin, which are commonly taken to prevent heart attacks. While nosebleeds in these cases may be a side effect of the medication rather than a stroke, it is still important to see a doctor to manage the nosebleeds and ensure the patient can continue taking the necessary medication.

In addition, turbulent airflow, often caused by a deviated nasal septum, can lead to frequent nosebleeds. Cold, dry air can also be a trigger. Individuals with a platelet condition that impairs their ability to form blood clots may also be more prone to recurrent nosebleeds.

If nosebleeds are interfering with daily activities and impacting your quality of life, it is important to see a specialist to determine the underlying cause and receive appropriate treatment.

HHT is a rare genetic disorder that can cause severe nosebleeds

While nosebleeds are not usually a primary symptom of a stroke, they can be a sign of a rare genetic disorder called Hereditary Hemorrhagic Telangiectasia (HHT). HHT affects about 1 in 5,000 to 1 in 10,000 people and is characterised by abnormal blood vessel formation. Those with HHT develop small lesions called telangiectases, which can rupture and bleed. The most common symptom of HHT is frequent and severe nosebleeds, which can begin as early as infancy but typically start after the age of 12.

People with HHT develop abnormal blood vessels that are fragile and prone to bleeding. These abnormal vessels can form anywhere in the body, including the nose, lungs, brain, gastrointestinal tract, skin, and liver. In the skin, these abnormal vessels appear as small red spots, usually on the hands, face, and inside the nose, mouth, or lips. Larger abnormal vessels, called arteriovenous malformations (AVMs), can range from several millimetres to several centimetres in size. AVMs can have serious consequences, such as causing a stroke if they form in the lungs or brain.

HHT is often undiagnosed or misdiagnosed, and the average time from the first symptom to diagnosis is about 30 years. If you experience frequent and severe nosebleeds, it is important to consult a doctor and specifically inquire about HHT, especially if you have a family history of the disorder. While there is no cure for HHT, early diagnosis and treatment can prevent life-threatening complications and improve quality of life.

Classic stroke symptoms include one-sided facial paralysis or numbness

Classic Stroke Symptoms

Other classic stroke symptoms include:

• Drooping on one side of the face
• Arm weakness or numbness
• Speech difficulty
• Double vision or other visual disturbances
• Cognitive impairment
• Severe headache

If you or someone you know is experiencing these symptoms, call 911 immediately. Early treatment improves survival rates and lowers disability rates.

A stroke can happen to anyone at any time

Nosebleeds, or "epistaxis" as doctors call it, are usually isolated incidents that stop on their own. However, for some, they can be a regular occurrence. While nosebleeds are almost never a primary symptom of a stroke, they can sometimes be linked.

Strokes, or "brain attacks," occur when blood flow to the brain is stopped or disrupted, causing brain cells to die. This can lead to a loss of brain function, impacting various abilities controlled by the affected area of the brain. Anyone can suffer a stroke at any age, but certain risk factors can increase the likelihood, such as high blood pressure, heart disease, diabetes, smoking, and abnormal heart rhythm.

Strokes are medical emergencies that require immediate attention. The classic symptoms of a stroke include sudden onset of facial drooping, one-sided facial paralysis or numbness, difficulty with speech, one-sided body paralysis, double vision, and cognitive impairment.

While nosebleeds alone are typically not a primary indicator of a stroke, they can be linked in certain cases. Recurrent nosebleeds may be a sign of an underlying health issue and should not be ignored. In adults, turbulent airflow, especially with a deviated nasal septum, can lead to nosebleeds. Additionally, individuals taking aspirin or blood thinners may experience nosebleeds as a side effect.

In rare cases, nosebleeds can be indicative of a more serious condition called Hereditary Hemorrhagic Telangiectasia (HHT). HHT is a rare genetic disorder that causes abnormal blood vessel formation and is often undiagnosed or misdiagnosed. The most common symptom of HHT is severe and frequent nosebleeds, but it can also cause abnormal blood vessels in other parts of the body, leading to ischemic strokes, brain abscesses, or hemorrhagic strokes.

If you experience very frequent and severe nosebleeds, it is important to consult a specialist to determine the underlying cause. While nosebleeds are typically not a primary symptom of a stroke, they can sometimes be linked to underlying health conditions that may increase the risk of stroke.
