Many people with low blood pressure don't have any symptoms. However, common symptoms of low blood pressure include dizziness, feeling faint or weak, fast or irregular heartbeat, vomiting, dehydration, blurred vision, confusion, breathing very fast and even shock in extreme cases. If you experience any of these symptoms, seek diagnosis and treatment at the nearest health unit. If a person goes into shock, bring them to the health unit IMMEDIATELY.
