By Reader's Digest Editors
A brief digest about this topic
For optimal health, doctors recommend keeping blood pressure below 120/80. But is there a point below which blood pressure is too low? While levels under 90/60 are technically considered low blood pressure, it’s only a problem if you’re experiencing dizziness or feeling faint—or serious symptoms such as shock. Other signs that low blood pressure might be dangerous include dehydration, intense thirst, blurred vision, nausea, cold and clammy skin, tiredness and depression. The cause could be an infection, certain medications, pregnancy, heart or hormone problems, an allergic reaction, serious blood loss, or a vitamin B12 or folic acid deficiency.
