Low blood pressure is often seen as a good thing — and for many people, it is. But when blood pressure drops below 90/60 mmHg, it can start to cause problems. Dizziness, fatigue, and fainting are some of the signs that your blood pressure may be too low. Understanding the underlying cause is key to getting it under control. Here are ten possible reasons behind a sudden or chronic dip in blood pressure.

1. Heart Problems

Heart conditions that limit blood flow — such as arrhythmias, heart failure, valve disorders, or recent heart attacks — can cause a dangerous drop in blood pressure. When the heart can’t pump blood effectively, organs and tissues don’t get the oxygen they need. In some cases, abnormal rhythms (arrhythmias) disrupt the heart’s ability to circulate blood entirely, leading to fainting or shock.
