Orthostatic Hypotension: When Standing Causes a Sudden Drop in Blood Pressure

Feeling dizzy or lightheaded when you stand up? You might be experiencing orthostatic hypotension, a condition where blood pressure drops significantly upon standing, causing temporary discomfort and, in some cases, more serious health risks.

What is Orthostatic Hypotension?

Orthostatic hypotension, also known as postural hypotension, occurs when the body struggles to regulate blood pressure upon standing. Normally, the autonomic nervous system ensures a smooth transition when you move from sitting or lying down to standing. However, in individuals with this condition, the blood vessels fail to constrict appropriately, leading to a sudden decrease in blood pressure.

Symptoms to Watch For

While mild cases may only cause momentary discomfort, severe cases can increase the risk of falls and fainting, especially in older adults. Common symptoms include:

• Dizziness or lightheadedness upon standing

• Blurred vision

• Weakness or fatigue

• Nausea

• Fainting or blackouts

If you experience these symptoms frequently, it is crucial to seek professional evaluation.

Causes and Risk Factors

Several factors contribute to orthostatic hypotension:

• Dehydration – Insufficient fluids can lower blood pressure.

• Nervous system disorders – Conditions like Parkinson’s disease and diabetes can impair autonomic function.

• Heart conditions – Heart failure or arrhythmias may disrupt proper blood circulation.

• Medications – Certain blood pressure medications, diuretics, or antidepressants can contribute.

• Prolonged bed rest – Extended periods of inactivity can weaken circulatory response.

Diagnosis and Management

Orthostatic hypotension is typically diagnosed through blood pressure tests in different positions—lying down, sitting, and standing. Additional tests may assess autonomic function and cardiovascular health.
