Orthostatic hypotension symptoms

Orthostatic hypotension usually occurs when one stands up after sitting or lying down for a long period of time. This happened because in the standing position, blood tends to pool in the legs and the heart may not be able to pump blood efficiently to the brain. This results in orthostatic hypotension. It is characterized by symptoms like lightheadedness, dizziness, blurred vision, weakness, nausea, confusion, and headache. Some people may experience mild tremors or shivering after an episode of orthostatic hypotension. This condition can occur in anyone at anytime. People with diabetes, nervous system disorders, and pregnant women are more prone to orthostatic hypotension than others. In older people, atherosclerosis or hardening of the arteries due to deposition of fats, lipids contribute to decreased blood flow and orthostatic hypotension. In pregnant women, the changes in the circulatory system are responsible for increased occurrence of postural hypotension. Physical exertion, sweating can result in loss of fluids and dehydration which in turn contributes to low blood pressure. The symptoms of this condition are generally mild and resolve on their own after a period of time. It is not a cause for concern if it occurs occasionally and resolves on its own. However, if orthostatic hypotension occurs frequently and the patient passes out often, it is essential to consult a doctor since it could be indicative of underlying serious conditions.
