Orthostatic Intolerance

Orthostatic intolerance (OI) is a condition in which a person experiences symptoms such as lightheadedness, dizziness, and fatigue when standing up from a sitting or lying down position. It is caused by a decrease in blood pressure when standing, which can lead to a decrease in blood flow to the brain. OI can be caused by a variety of medical conditions, including dehydration, diabetes, and certain medications. It can also be caused by a lack of physical activity or prolonged bed rest.

Causes of Orthostatic Intolerance

OI can be caused by a variety of medical conditions, including dehydration, diabetes, and certain medications. It can also be caused by a lack of physical activity or prolonged bed rest. Other causes of OI include anemia, heart disease, and certain neurological conditions. In some cases, OI can be caused by an underlying medical condition, such as an autoimmune disorder or a hormonal imbalance.

Diagnosis of Orthostatic Intolerance

OI is typically diagnosed through a physical exam and a review of the patient's medical history. The doctor may also order tests such as an electrocardiogram (ECG) or an echocardiogram (ECHO) to check for any underlying heart conditions. Blood tests may also be ordered to check for anemia or other medical conditions that could be causing OI.

Prevention of Orthostatic Intolerance

The best way to prevent OI is to maintain a healthy lifestyle. This includes eating a balanced diet, exercising regularly, and drinking plenty of fluids. It is also important to avoid prolonged bed rest and to get up slowly when standing from a sitting or lying down position. If OI is caused by a medical condition, it is important to follow the doctor's instructions for managing the condition.
