How can blood pressure affect vertigo?

Blood pressure plays a big role in vertigo, and both high blood pressure (hypertension) and low blood pressure (hypotension) can be the cause of or exacerbating factors for vertigo symptoms. Let’s discuss how blood pressure influences vertigo:

1. Low Blood Pressure (Hypotension) and Vertigo
If the blood pressure becomes too low, the brain doesn’t receive proper blood supply, resulting in dizziness or vertigo. Such a situation is termed orthostatic hypotension (abrupt decrease in blood pressure during change of posture from lying to sitting or while rising from a sitting position). It may result in:

Lightheadedness and dizziness: Your body needs some time to accommodate the change of position, so you become lightheaded or dizzy.

Vertigo: When the brain does not receive sufficient blood, it leads to a feeling of spinning, or vertigo. This is especially common when standing up quickly from a lying or sitting position after being inactive for a long period of time.

Fainting: In severe cases, low blood pressure can cause you to faint (syncope), often preceded by dizziness or vertigo.

Some of the most common reasons for low blood pressure with vertigo are:

Dehydration: When the body loses water (due to excessive sweating, diarrhea, or vomiting), it can cause weakness, dizziness, and fatigue.

Medications: Some medications that are prescribed for high blood pressure or diuretics can result in abnormally large drops in blood pressure, thereby increasing the risk of vertigo.

Heart problems: Conditions like a slow heart rate (bradycardia), heart valve problems, or heart attack can result in low blood pressure and subsequent vertigo.

Endocrine disorders: Conditions like underactive thyroid (hypothyroidism), adrenal insufficiency (Addison’s disease), or low blood sugar (hypoglycemia) may also cause low blood pressure and vertigo.

2. Vertigo and High Blood Pressure (Hypertension)
Hypertension can also cause vertigo, but the etiology is different from that of low blood pressure. This is how hypertension can influence vertigo:

Vascular changes: Chronic high blood pressure can weaken blood vessels like those in the inner ear and brain, causing them to offer a poor supply of blood and leading to vertigo. High blood pressure can ultimately harden and constrict arteries over a long period, reducing the supply of oxygenated blood to the brain, leading to vertigo and dizziness.

Risk for stroke: One of the primary risk factors for stroke is high blood pressure, and a stroke, especially in the brainstem or cerebellum, can produce central vertigo. Stroke can impair coordination of spatial orientation and balance by the brain, leading to vertigo and other neurological signs.

Vestibular dysfunction: In some cases, high blood pressure can affect the vestibular system (brain and inner ear mechanism of balance), causing vertigo, dizziness, or imbalance symptomatology.

Hypertensive crisis: If the blood pressure rapidly rises to abnormally high levels (a hypertensive crisis), it can cause sudden and severe dizziness, nausea, and vertigo due to an acute increase in pressure. This requires immediate medical intervention.

3. Blood Pressure Medications and Vertigo
Prescription drugs for controlling high blood pressure can also cause vertigo as a side effect, particularly on initiation of a new drug or altering dosing. Some of the common blood pressure medications that could lead to vertigo include:

Diuretics (water pills) – These can lead to excessive lowering of blood pressure, especially upon standing, and cause dizziness and vertigo.

ACE inhibitors or beta-blockers – These could lower blood pressure, and in some cases, can also create dizziness or vertigo as a side effect.

4. Managing Blood Pressure-Associated Vertigo
Keeping your blood pressure under control can help improve symptoms of vertigo:

For Low Blood Pressure (Hypotension):

Drink plenty of liquids to maintain a hydrated body as dehydration can also exacerbate low blood pressure and vertigo.

Increase salt intake (under physician guidance) to enhance blood pressure levels.

Wear compressive stockings to improve circulation and prevent blood pooling at the lower limbs, especially during rising from sitting position.

Rise slowly from the sitting or lying position and avoid abrupt changes in position in order to give time for your body to adjust.

It may be required to change medicines if medicines are inducing hypotension and vertigo.

For High Blood Pressure (Hypertension):

Medications like ACE inhibitors, calcium channel blockers, or diuretics can reduce blood pressure safely and reduce the risk of vertigo.

Monitor blood pressure regularly to maintain it within a healthy range.

Lifestyle modifications such as a low-sodium diet, exercise, and stress reduction can manage blood pressure and reduce the risk of vertigo.

5. When to See a Doctor
If you experience vertigo with hypertension or hypotension, it is advisable to visit a healthcare provider for an assessment. They will be able to determine the cause of the vertigo and adjust treatment accordingly. Medical attention should be sought if:

Severe or acute vertigo is experienced.

Vertigo is accompanied by chest pain, severe headache, vision change, or weakness (stroke syndrome).

There is a history of stroke or coronary heart disease.
Conclusion
Both low and high blood pressure can significantly affect vertigo but in different ways. Low blood pressure can cause vertigo by reduced flow of blood to the brain, especially on change of position. High blood pressure has the ability to weaken blood vessels over a long period of time and lead to stroke risk, both of which may cause vertigo. The regulation of blood pressure to within normal parameters and management of underlying conditions may decrease symptoms of vertigo as well as overall balance and well-being.

The connection between vertigo and cardiovascular disease is in how circulatory problems and changes in blood flow can affect the brain and the inner ear, both of which are involved in balance and spatial orientation. Below are the main ways in which cardiovascular disease can cause vertigo:

1. Poor Blood Circulation (Inadequate Blood Supply to the Brain)
The brain along with the regions responsible for balance such as the brainstem and cerebellum require a steady supply of nutrients and oxygen by means of blood circulation to function optimally. When cardiovascular issues affect circulation, it may result in inadequate blood supply to these regions, causing vertigo or dizziness. This can be due to:

Atherosclerosis: A buildup of fatty plaques in the arteries may reduce blood flow to the brain, especially if it occurs in the vertebrobasilar arteries, which supply blood to the brainstem and cerebellum. This may lead to dizziness or vertigo.

Low Blood Pressure (Hypotension): Conditions like orthostatic hypotension (sudden decrease in blood pressure when standing from lying down) or chronically low blood pressure can reduce blood flow to the brain, causing dizziness or vertigo, particularly when standing or changing position.

Transient Ischemic Attacks (TIA): A TIA, or “mini-stroke,” is a temporary interruption of blood flow to the brain. TIAs may lead to sudden dizziness, vertigo, or imbalance, often with other symptoms of the nervous system. Though symptoms of a TIA are temporary, they are often a sign of a more severe stroke.

2. Arrhythmias (Irregular Heartbeats)
Atrial arrhythmias such as AFib or bradycardia (slow heart rate) may result in inadequate supply of oxygen-rich blood to the brain. When the heart does not beat properly or beat fast enough, it won’t be able to circulate enough blood to match the demand, and it induces dizziness and vertigo. Arrhythmias, if severe, can induce syncope (loss of consciousness) or unconsciousness as a result of reduced cerebral perfusion.

3. Heart Failure
Heart failure is the impaired ability of the heart to pump blood. Therefore, delivery of blood to the critical organs, e.g., the brain, is reduced. This leads to dizziness, lightheadedness, and vertigo, especially on sudden rising or on exertion.

Right-sided heart failure can result in body fluid retention, such as in the lungs, and reduce the delivery of oxygen to the brain, resulting in dizziness.

Left-sided heart failure can reduce blood delivery to the brain, causing symptoms including dizziness and vertigo.

4. Stroke and Cerebrovascular Disease
Stroke or cerebrovascular accident (CVA) refers to an interruption of brain blood flow, either by a blood clot (ischemic stroke) or hemorrhage (hemorrhagic stroke). When a stroke affects regions of the brain that are concerned with balance and coordination (for example, brainstem or cerebellum), vertigo and dizziness ensue due to neurological damage. Stroke can result in acute, severe vertigo with other accompanying signs of dysarthria in speaking, weakness, or loss of coordination.

5. Dehydration and Electrolyte Imbalances
Cardiovascular complications such as dehydration or electrolyte imbalance may affect the heart and vascular function. If blood volume decreases due to dehydration or an electrolyte imbalance (e.g., low sodium or potassium), it may cause low blood pressure and poor circulation, resulting in dizziness and vertigo.

6. Postural Orthostatic Tachycardia Syndrome (POTS)
POTS is a condition where the heart rate increases significantly when standing, with a predisposition to decreased blood pressure. The condition can lead to dizziness, lightheadedness, and vertigo, particularly on transitioning from a sitting to a standing position. POTS has an association with circulatory disturbances and can be a result of cardiovascular dysfunction.

7. Vestibular Dysfunction as a Result of Cardiovascular Events
In some cases, vestibular dysfunction (balance and inner ear disorder) can be caused by cardiovascular events, especially if there is reduced blood flow to the vestibular system of the inner ear. For example, ischemic events (reduced blood flow) in the vertebrobasilar artery, which supplies the brainstem and inner ear, can cause vertigo and other symptoms such as unsteadiness or loss of balance.

Symptoms of Vertigo Due to Cardiovascular Causes
In case cardiovascular disorders are the etiology of vertigo, the following signs might be noted:

Dizziness upon standing or a change in positions (for instance, lying to standing) might suggest low blood pressure or orthostatic hypotension.

Irregular pulse or palpitations with dizziness might suggest arrhythmias.

Sudden onset of severe vertigo along with other neurological findings (e.g., weakness, confusion, or speech difficulty) might suggest a stroke or TIA.

Chronic fatigue, shortness of breath, and leg or abdominal swelling can be symptoms of heart failure that cause vertigo.

Treatment of Vertigo With Cardiovascular Health
Treatment of vertigo with cardiovascular health will differ based on the underlying cardiovascular condition:

For Low Blood Pressure (Hypotension): Drinking more fluid, compression stockings, changing medicines, and using lifestyle changes (such as slowly getting up from a seated position) can relieve symptoms.

For Arrhythmias: Medications (e.g., beta-blockers or anticoagulants) or procedures (such as cardioversion or pacemaker insertion) may be used to stabilize the heart rhythm and improve blood flow.

For Stroke or TIA: Emergency medical treatment is required, with thrombolytics (clot-busting drugs), antiplatelets, and surgery to re-establish blood flow and reduce further damage.

For Heart Failure: Drugs like ACE inhibitors, beta-blockers, and diuretics will improve heart strength and circulation, reducing dizziness and vertigo.

For Postural Orthostatic Tachycardia Syndrome (POTS): Increasing fluid and salt intake, compression clothing, and exercise therapy can relieve symptoms.

Conclusion
The connection between vertigo and cardiovascular wellness is of great significance, as numerous cardiovascular illness involve the blood supply to the brain, leading to dizziness and loss of balance. Curing the underlying causative cardiovascular disease forms the cornerstone in the treatment of vertigo and in the overall maintenance of wellness. In the event that vertigo is constant, severe, or accompanied by symptoms like chest pain or weakness, instant medical attention should be accessed.
