Anaphylactic Shock Symptom
Low Blood Pressure
For low blood pressure to be a problem there needs to be a symptom associated with that low number. Readings below 120/80 may be normal depending upon the clinical situation. Many people have systolic blood pressures below 100, but some people develop symptoms with pressures that low. Symptoms of low blood pressure occur because one or more of the body's organs is not getting enough blood supply.
