💉HYPOTENSION 💊
Hypotension, also known as low blood pressure, is a condition characterized by a blood pressure reading that is lower than normal. Blood pressure is the force exerted by circulating blood on the walls of blood vessels. It is typically measured in millimeters of mercury (mmHg) and consists of two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number).
Normal blood pressure is typically considered to be around 120/80 mmHg. Hypotension is generally defined as a blood pressure reading of 90/60 mmHg or lower. However, symptoms of hypotension can vary based on the individual's baseline blood pressure and overall health status.
Hypotension can be classified into different types, including:
Orthostatic Hypotension: This type of hypotension occurs when there is a sudden drop in blood pressure upon standing up from a sitting or lying position. It can lead to symptoms such as dizziness, lightheadedness, and fainting.
Postprandial Hypotension: This type of hypotension occurs after eating a meal and is more common in older adults. It can cause a temporary drop in blood pressure due to blood flow being redirected to the digestive system.
Neurally Mediated Hypotension: This type of hypotension is thought to be caused by a miscommunication between the brain and the cardiovascular system, leading to a sudden drop in blood pressure, particularly during prolonged standing.
Severe Hypotension: In some cases, hypotension can be severe and result in inadequate blood flow to vital organs, leading to shock, organ damage, and even death if not promptly treated.
Causes of hypotension can include:
Dehydration
Severe infection (septic shock)
Heart problems (e.g., heart failure, heart attack)
Endocrine disorders (e.g., adrenal insufficiency)
Medications (e.g., blood pressure-lowering drugs)
Neurological conditions (e.g., autonomic dysfunction)
Anaphylaxis (severe allergic reaction)
Symptoms of hypotension can vary but may
