Orthostatic Hypotension Results from Reduced Blood Flow to the Brain

Orthostatic hypotension can be caused by various factors, and it may result from a combination of underlying conditions. Some common causes include:

Dehydration

Insufficient fluid in the body can lead to a decrease in blood volume, contributing to low blood pressure upon standing.

Medications

Certain medications, such as antihypertensives, diuretics, and some antidepressants, can cause orthostatic hypotension as a side effect.

Nervous system disorders

Conditions that affect the autonomic nervous system, which regulates involuntary bodily functions, can contribute to orthostatic hypotension. Examples include Parkinson’s disease, multiple system atrophy, and pure autonomic failure.

Heart problems

Conditions that affect the heart, such as extremely low heart rate (bradycardia), heart valve problems, or heart attack, may lead to orthostatic hypotension.

Endocrine disorders

Certain hormonal imbalances, such as adrenal insufficiency (Addison’s disease) or low blood sugar (hypoglycemia), can be associated with orthostatic hypotension.

Anemia

A lower-than-normal red blood cell count or decreased hemoglobin levels can affect the blood’s ability to carry oxygen, potentially leading to orthostatic hypotension.

Age

Older adults are more prone to orthostatic hypotension due to changes in blood vessel elasticity and autonomic nervous system function.

Prolonged bed rest

Spending extended periods in a horizontal position, such as during illness or hospitalization, can lead to orthostatic hypotension when a person returns to an upright position.

Neurological conditions

Disorders affecting the nervous system, such as peripheral neuropathy or certain neuropathies, can contribute to orthostatic hypotension.

It’s important to note that sometimes orthostatic hypotension may occur without an underlying medical condition and may be a normal response in certain situations. However, persistent or severe symptoms should be evaluated by a healthcare professional to identify and address any potential underlying causes.

Diagnosing orthostatic hypotension typically involves a combination of medical history assessment, physical examination, and specific tests to evaluate blood pressure changes in different positions. Here are the common steps involved in diagnosing orthostatic hypotension:

Medical History

• The healthcare provider will inquire about your symptoms, including any episodes of dizziness, lightheadedness, or fainting.
• Information about medications, medical conditions, and recent changes in health will be reviewed to identify potential causes.

Physical Examination

• The healthcare provider will perform a thorough physical examination, paying attention to blood pressure measurements in various positions (lying down, sitting, and standing).
• They may check for signs of dehydration, neurological disorders, or other conditions that could contribute to orthostatic hypotension.

Orthostatic Blood Pressure Monitoring

• Orthostatic blood pressure measurements involve taking blood pressure readings in different positions.
• Typically, the healthcare provider will measure blood pressure while the person is lying down, sitting, and standing at specific intervals (e.g. 1, 3, and 5 minutes after standing).
• A significant drop in systolic blood pressure (typically defined as a decrease of 20 mm Hg or more) or diastolic blood pressure when moving from a lying or sitting to a standing position is indicative of orthostatic hypotension.

Tilt Table Test

• In some cases, a tilt table test may be performed. During this test, the individual is strapped to a table that can be tilted to simulate changes in posture. Blood pressure and heart rate are monitored throughout the test to assess how the body responds to changes in position.

Blood Tests

• Blood tests may be conducted to assess factors such as blood sugar levels, electrolyte balance, and complete blood count to identify any underlying conditions contributing to orthostatic hypotension.

Electrocardiogram (ECG or EKG)

• An ECG may be performed to evaluate the heart’s electrical activity and rule out any cardiac abnormalities.

Holter Monitor or Event Monitor

• In some cases, a portable device like a Holter monitor or event monitor may be used to continuously record the heart’s electrical activity over a period, helping to identify any irregularities during daily activities.

It’s important to consult with a healthcare professional if you are experiencing symptoms suggestive of orthostatic hypotension. Diagnosing the condition allows for appropriate management and treatment, which may involve lifestyle modifications, medication adjustments, or addressing underlying health issues.

Managing orthostatic hypotension involves a combination of lifestyle modifications, behavioral strategies, and, in some cases, medical interventions. Here are some tips for managing orthostatic hypotension:

Hydration

Ensure adequate fluid intake to prevent dehydration, as dehydration can contribute to low blood pressure. Aim for at least eight glasses of water per day, and more if needed based on individual requirements.

Salt Intake

Increase salt intake within the recommended limits, as salt can help retain fluid and raise blood pressure. However, individuals with certain health conditions, such as hypertension, should consult with their healthcare provider before making significant changes to their salt intake.

Gradual Changes in Position

When moving from a lying or sitting position to standing, do so gradually. Take your time and allow your body to adjust to the change in posture.

Leg Exercises

Perform leg exercises, such as leg lifts and ankle pumps, before standing up. These exercises help activate the muscles that assist in pumping blood back to the heart.

Compression Stockings

Compression stockings can help reduce the pooling of blood in the legs by providing external pressure on the blood vessels. Consult with a healthcare professional to determine the appropriate level of compression.

Small, Frequent Meals

Instead of large meals, opt for smaller, more frequent meals throughout the day. This can help prevent a sudden drop in blood pressure after eating.

Avoid Alcohol and Caffeine

Limit or avoid the consumption of alcohol and caffeine, as these substances can contribute to dehydration and exacerbate orthostatic hypotension.

Medication Management

If orthostatic hypotension is caused or worsened by certain medications, consult with a healthcare provider to discuss potential adjustments or alternative medications.

Elevate the Head of the Bed

If symptoms are worse in the morning, consider elevating the head of the bed by a few inches. This may help reduce symptoms upon waking.

Stay Cool

Avoid hot environments, as heat can dilate blood vessels and worsen symptoms. Use fans, wear lightweight clothing, and stay well-ventilated in warmer conditions.

Regular Exercise

Engage in regular, moderate exercise to improve overall cardiovascular health. However, consult with a healthcare professional before starting a new exercise program.

Monitor Blood Pressure

Regularly monitor blood pressure, especially after changes in medication or lifestyle. This helps in identifying trends and assessing the effectiveness of management strategies.

Individuals with orthostatic hypotension should work closely with their healthcare provider to develop a personalized management plan. In some cases, medications may be prescribed to help manage symptoms, and adjustments to treatment may be necessary over time. It’s crucial to maintain open communication with healthcare professionals to ensure optimal care and symptom control.
