ortostatickou

Ortostatisk refers to a postural change, specifically the transition from a lying or sitting position to a standing position. It is often used in the context of medical conditions that affect blood pressure regulation. When a person stands up, gravity pulls blood towards the lower extremities. Normally, the body compensates for this by increasing heart rate and constricting blood vessels to maintain adequate blood flow to the brain. If this compensatory mechanism is impaired, a person may experience symptoms of orthostatic hypotension, such as dizziness, lightheadedness, or even fainting.

Orthostatic hypotension can be caused by various factors, including dehydration, certain medications (like diuretics or blood pressure medications), neurological disorders, and aging. Doctors may perform an orthostatic vital signs test, which involves measuring blood pressure and heart rate while the patient is lying down, sitting, and standing. This test helps to identify if orthostatic changes are contributing to a patient's symptoms. Treatment strategies focus on addressing the underlying cause and may include increasing fluid intake, adjusting medications, or wearing compression stockings. It is a common phenomenon that can affect individuals of all ages, but it is more prevalent in older adults.
