Low blood pressure, or hypotension, is often seen as a sign of good health. However, like any medical condition, when it goes to extremes, it can become a serious concern. Blood pressure measures the force of blood against the walls of your arteries as your heart pumps it around your body.
It is usually expressed as two numbers, such as 120/80 mm Hg. The first number, systolic pressure, represents the force when the heart beats, while the second number, diastolic pressure, is the force when the heart rests between beats.
Low blood pressure is generally considered to be a systolic reading below 90 mm Hg or a diastolic reading below 60 mm Hg. It is important to note that everyone's ideal blood pressure may vary, and what's low for one person may be normal for another.
Can low blood pressure be fatal?
While low blood pressure is often benign, severe and prolonged hypotension can have fatal consequences. In extreme cases, it can lead to inadequate blood flow to vital organs, including the brain, heart, and kidneys. Insufficient blood supply to these organs can result in organ damage or failure, which can be life-threatening.
5 symptoms of extreme low blood pressure
1. Dizziness and lightheadedness: Feeling faint when standing up quickly or changing positions is a common symptom of low blood pressure. This is often referred to as orthostatic hypotension.
2. Fainting (Syncope): Sudden drops in blood pressure can cause you to lose consciousness. Fainting is a red flag and requires immediate medical attention.
3. Nausea and fatigue: Chronic low blood pressure can lead to constant feelings of fatigue and nausea. These symptoms can significantly impact your daily life.
4. Blurred vision: A lack of blood flow to the eyes can cause temporary vision problems or blurriness.
5. Confusion and difficulty concentrating: Inadequate blood supply to the brain can result in confusion, difficulty focussing, and memory problems.
Prevention and management:
Maintaining a healthy blood pressure range is crucial. Dehydration can lead to low blood pressure. Ensure you drink enough water throughout the day, especially in hot weather or during physical activity. While excessive salt intake is unhealthy, some salt is necessary for maintaining blood pressure.
Consult with a healthcare professional to determine your ideal sodium intake. Engage in regular physical activity, which helps improve circulation and maintain a healthy blood pressure. A diet rich in fruits, vegetables, and whole grains can also help regulate blood pressure. Avoid excessive alcohol and caffeine consumption. Chronic stress and certain medical conditions like diabetes also contribute to fluctuations in blood pressure. By taking preventive measures and seeking medical advice when necessary, you can maintain a healthy blood pressure range and reduce the risk of fatal outcomes associated with severe hypotension.
