What causes low blood pressure?
There are many causes of low blood pressure. A significant portion of chronic hypotension is due to physical constitution, with some patients who are generally frail having consistently low blood pressure but no symptoms. This type is quite common. Secondly, postural hypotension is also fairly common, often seen in elderly people or those taking antihypertensive medications, such as receptor blockers. These patients may experience transient dizziness and transient low blood pressure when getting up, known as postural hypotension. Moreover, the more common type is acute, sustained low blood pressure, which includes various causes of shock, myocardial infarction, cardiac tamponade, or acute blood loss, which can be life-threatening conditions requiring urgent treatment.
