What are 3 causes of hypotension?

Three common causes of hypotension include dehydration, which reduces blood volume; heart problems, such as bradycardia or heart failure, which can impair the heart's ability to pump blood effectively; and severe infections (septicemia) that can lead to septic shock, causing blood vessels to dilate and blood pressure to drop. Other factors may include significant blood loss from trauma or internal bleeding, as well as certain medications that lower blood pressure.
