Yes, it can. If it drops below 90/60 mmHg, doctors will say
you have low blood pressure.
It is not always bad news. Low blood pressure can be a sign
of good health in people who are very fit and have a slow pulse. As a bonus, people
with low blood pressure tend to lead longer lives.
You can also experience low blood pressure from overheating;
having too little blood circulating (from blood donation or bleeding heavily);
being dehydrated; being pregnant; taking one of many different types of
medicine; or having a lot of drugs or alcohol in your system.
Certain medical conditions may also cause your blood
pressure to drop. These include allergic reactions, infections, certain heart
conditions, nutritional deficiencies or severe pain.
There is also a type of low blood pressure called ‘postural
hypotension’ where blood pressure drops suddenly when a person stands, making
them feel dizzy.
Low blood pressure can cause some unpleasant symptoms. These
- Light headedness or dizziness
- Blurry vision
- Pale, clammy skin
See your doctor if you think you have symptoms of low blood
pressure as an underlying cause may need treatment. But if it isn’t causing you
problems, treatment won’t be needed.
Your doctor may advise that you take precautions to prevent
episodes of low blood pressure, such as avoiding dehydration, hot showers, or
standing up too quickly.
