Low blood pressure, also known as hypotension, is generally considered a blood pressure reading lower than 90 millimeters of mercury (mm Hg) for the top number (systolic) or 60 mm Hg for the bottom number (diastolic)
. While low blood pressure can be benign in some cases, it can also be dangerous, especially when it drops suddenly or occurs with symptoms
. Some of the risks and dangers associated with low blood pressure include:
- Sudden drop in blood pressure: A change of just 20 mm Hg can cause dizziness and fainting
- Extreme low blood pressure: Big drops, such as those caused by uncontrolled bleeding, severe infections, or allergic reactions, can be life-threatening
- Shock: Symptoms of shock include confusion, cold and clammy skin, decrease in skin coloration (pallor), rapid and shallow breathing, and weak and rapid pulse
Low blood pressure can be caused by various factors, including dehydration, prolonged bed rest, pregnancy, certain medical conditions, and some medications
. It is essential to find out what's causing low blood pressure to determine if treatment is necessary. If you experience symptoms of low blood pressure, such as dizziness, fainting, fatigue, or blurred vision, it is crucial to consult a healthcare professional for proper evaluation and management
. In some cases, low blood pressure may be a sign of an underlying health condition, especially when it drops suddenly or occurs with symptoms
