Orthostatic Hypotension: Causes and Treatment

Orthostatic hypotension is a fairly common condition, though it might indicate a more serious disorder. At CardioVascular Health Clinic, we are proud to provide comprehensive treatment for a broad scope of heart care concerns, helping diverse patients manage and overcome complex medical disorders.

What Is Orthostatic Hypotension?

Orthostatic hypotension (or postural hypotension) is a type of low blood pressure that occurs when rising after being in a seated or prone position. This condition can lead to disorientation or dizziness and sometimes loss of consciousness.

It also varies in medical significance. It’s fairly common for the episodes to occur rarely and last only a few seconds or minutes. However, prolonged orthostatic hypotension may indicate underlying health issues. It's crucial to see a medical professional if you regularly feel dizzy when standing suddenly.

Sporadic cases typically have a clear cause, such as extreme heat or dehydration, and require only fluids and rest to overcome. However, recurring orthostatic hypotension generally indicates an underlying medical issue. The appropriate treatment will depend upon the causal factor. 

What Are the Symptoms of Orthostatic Hypotension?

The primary indication of this condition is feeling lightheaded or faint upon standing up after being seated. Symptoms might last between a few seconds to a minute or two. Additional symptoms include

• Blurred vision
• Feeling weak
• Loss of consciousness
• Disorientation
• Lack of focus
• Headache
• Heart racing
• Nausea

Infrequent lightheadedness might be caused by a lack of fluids, excessive heat, or low blood sugar. Medical attention is probably not required if the symptoms rarely occur and have an identifiable cause.

However, if you cannot account for feeling dizzy -- or if the spells are unpredictable -- there might be a significant health issue affecting you. If loss of consciousness after sitting for an extended period is fairly regular, seek medical assistance immediately.

What Causes Orthostatic Hypotension?

Blood flow from the heart to the organs and extremities is easier when lying down or seated. However, in a standing position, blood flow from the lower portion of the body requires more effort. Numerous issues might contribute to orthostatic hypotension, including the following

• Dehydration
• Anemia
• Diabetes
• Thyroid disease
• Heart valve disease
• Certain medications
• Pregnancy

Orthostatic hypotension can put you at risk of experiencing injuries from fainting or losing balance. If your blood pressure fluctuates significantly, you might also be at higher risk of stroke.

Orthostatic Hypotension Treatment

Treatment for orthostatic hypotension will depend upon the underlying cause; if a medical condition is triggering low blood pressure, it must be addressed.

Certain lifestyle modifications can help manage this condition, including

• Staying hydrated. Dehydration can exacerbate orthostatic hypotension. Try to always have a water bottle nearby.
• Increasing salt intake. Everyone has different sodium needs. For some, an increase in salt intake can help with symptoms.
• Maintaining blood sugar levels. Eating several small meals throughout the day can help keep your blood sugar from dropping significantly.
• Getting regular exercise. Physical fitness is a highly effective management tool for orthostatic hypotension and can mitigate symptoms. However, do not exercise in extreme heat.
• Standing up slowly. If you feel faint when standing suddenly after lying down, take a moment, breathe deeply, and rise slowly.
