Low blood pressure, also known as hypotension, occurs when blood pressure is much lower than normal. This means that the heart, brain, and other parts of the body may not get enough blood. Low blood pressure can cause no noticeable symptoms, or it might cause dizziness, lightheadedness, unsteadiness, dimming or blurring of vision, agitation or other behavior changes, weakness, fatigue or lethargy, confusion, nausea, cold, clammy skin, fainting, and pale skin. If blood pressure gets seriously low, the body might not get enough oxygen to carry out its normal functions, which can impair the functioning of the heart and brain and cause breathing problems. In severe cases, it can lead to shock, where the organs shut down.

The causes of low blood pressure range from dehydration to serious medical conditions. Some common causes of low blood pressure include:

• Dehydration
• Blood loss from severe injuries
• Pregnancy
• Heart and heart valve conditions
• Endocrine problems
• Certain medications
• Anaphylaxis or immune reactions to severe infections
• Shock

Its important to find out whats causing low blood pressure so that it can be treated, if necessary. If you have consistently low blood pressure readings but feel fine, your healthcare provider may just monitor you during routine health checkups.
