Hypotension is low blood pressure, especially in the arteries of the systemic circulation. Hypotension is generally considered if systolic blood pressure less than 90 millimeters of mercury (mm Hg) or diastolic less than 60 mm Hg.
The cardinal symptoms of hypotension include lightheadedness or dizziness.
If the blood pressure is sufficiently low, fainting and often seizures occur.
Low blood pressure is sometimes associated with certain symptoms, many of which are related to causes rather than effects of hypotension:
· chest pain
· shortness of breath
· irregular heartbeat
· fever higher than 38.3 °C (101 °F)
· headache
· stiff neck
· severe upper back pain
· cough with sputum
· Prolonged diarrhea or vomiting
· dyspepsia (indigestion)
· dysuria (painful urination)
· adverse effect of medications
· acute, life-threatening allergic reaction
· seizures
· loss of consciousness
· profound fatigue
· temporary blurring or loss of vision
· connective tissue disorder Ehlers-Danlos Syndrome
· Black tarry stools
