Guide To The Symptoms Of Dehydration

Orthostatic Hypotension

Orthostatic hypotension occurs most frequently with mild dehydration. Also known as postural hypotension, it refers to a drop in blood pressure that occurs when a patient stands up from a sitting or lying position. Patients with orthostatic hypotension typically feel dizzy or lightheaded upon standing, and they could experience nausea, confusion, blurred vision, or weakness. Fainting may occur in some cases. Since orthostatic hypotension could be a sign of a serious medical issue, patients should see a doctor if they experience frequent episodes of lightheadedness or dizziness upon standing. Emergency medical care is necessary if fainting occurs. To diagnose orthostatic hypotension, doctors will measure the patient's blood pressure while they are sitting and standing. If the systolic measurements differ by more than 20 mmHg, the diagnosis is confirmed. Patients may also need to have blood tests to fully investigate their symptoms, and in some instances, an electrocardiogram may be necessary. During testing for orthostatic hypotension, patients should let their doctor know about their fluid intake and about any symptoms that may be connected to dehydration.
