Hypotension

A medical condition characterized by low blood pressure, typically defined as a systolic blood pressure less than 90 millimeters of mercury (mm Hg) or a diastolic blood pressure less than 60 mm Hg.

 

Orthostatic Hypotension

Also known as postural hypotension, it is a form of low blood pressure that occurs when you stand up from sitting or lying down. It can cause dizziness, lightheadedness, or even fainting.

 

Primary Hypotension

Also called essential or idiopathic hypotension, it refers to low blood pressure without a known underlying cause. It may be a result of genetics or lifestyle factors.

 

Secondary Hypotension

Hypotension resulting from underlying medical conditions such as dehydration, heart problems, endocrine disorders, or neurological conditions.

 

Neurally Mediated Hypotension (NMH)

A type of low blood pressure that occurs after prolonged standing. It is believed to be caused by a miscommunication between the brain and the cardiovascular system.

 

Hypovolemic Shock

A severe form of hypotension resulting from extreme blood or fluid loss, often due to trauma, severe dehydration, or internal bleeding. It requires immediate medical attention.

 

Vasovagal Syncope

A temporary loss of consciousness due to a sudden drop in heart rate and blood pressure, often triggered by emotional stress, pain, or the sight of blood.

 

Anaphylactic Shock

A life-threatening condition characterized by a sudden drop in blood pressure, hives, difficulty breathing, and swelling of the face and throat, resulting from a severe allergic reaction.

 

Septic Shock

A serious condition that occurs when an overwhelming infection leads to a systemic inflammatory response, causing low blood pressure and multiple organ failure.

 

Distributive Shock

A type of shock characterized by widespread dilation of blood vessels, leading to inadequate blood flow to the body’s tissues and organs, resulting in low blood pressure. Examples include septic shock and anaphylactic shock.
