low blood pressure signals an underlying problem, especially when it drops suddenly or is accompanied by signs and symptoms such as:
Dizziness or lightheadedness Fainting (syncope) Blurred vision Nausea Fatigue Lack of concentration
Extreme hypotension can result in this life-threatening condition. Signs and symptoms include:
Confusion, especially in older people Cold, clammy, pale skin Rapid, shallow breathing Weak and rapid pulse
If you have indications of shock, seek emergency medical help.
If you have consistently low blood pressure readings but feel fine, your doctor is likely just to monitor you during routine exams.
Even occasional dizziness or lightheadedness may be a relatively minor problem — the result of mild dehydration from too much time in the sun or a hot tub, for example. Still, it’s important to see your doctor if you have signs or symptoms of hypotension because they can point to more-serious problems. It can be helpful to keep a record of your symptoms, when they occur and what you’re doing at the time.
