The American Heart Association reports that a blood pressure lower than 120/80 is considered normal. Low blood pressure is considered dangerous when it is accompanied by symptoms that include:
Severely low blood pressure (although there is no specific number at which blood pressure is considered too law) can indicate serious heart, endocrine or neurological disorders and can deprive the brain and other vital organs of oxygen and nutrients, leading to shock, which can be a life-threatening condition.
And fortunately for you, most doctors only consider long-term low blood pressure dangerous if it causes the above-listed symptoms.
One thing to keep in mind is that a sudden fall in blood pressure can be dangerous — even a change of just 20 mm Hg can cause dizziness or fainting, the AHA says.
Some rapid falls in blood pressure indicate a deeper underlying problem such as uncontrolled bleeding, severe infections or allergic reaction.
And it looks like your brother-in-law may be on to something with regard to the thyroid issue. Looks like endocrine problems may lead to low blood pressure. For details on other causes of low blood pressure, you may want to visit http://www.americanheart.org/presenter.jhtml?identifier=3034848
