Low Blood Pressure

Low blood pressure, also known as hypotension, happens when the force of blood against the artery walls is too low.

It is measured in millimeters of mercury (mm Hg), and generally, a reading below 90/60 mm Hg is considered low.

However, what’s low for one person may be normal for another. Some people may not feel any symptoms, while others may experience dizziness or fainting. In severe cases, low blood pressure can be life-threatening.

Common causes include dehydration or underlying medical conditions. It’s important to identify the cause so that proper treatment can be given if needed.

Low blood pressure symptoms can include:

• Blurred or fading vision.
• Dizzy or lightheaded feelings.
• Fainting.
• Fatigue.
• Trouble concentrating.
• Upset stomach.

For some people, low blood pressure can be a sign of another health problem, especially when it happens suddenly or comes with symptoms.

A sudden drop in blood pressure can be dangerous. Even a decrease of 20 mm Hg can cause dizziness or fainting for example, when systolic pressure drops from 110 mm Hg to 90 mm Hg. A large drop can be life-threatening and may happen due to severe bleeding, serious infections, or allergic reactions.

Very low blood pressure can lead to a serious condition called shock. Signs of shock include:

• Confusion, especially in older adults
• Cold, clammy skin
• Pale or bluish skin color
• Fast, shallow breathing
• Weak and rapid pulse

Low blood pressure can be managed effectively with the right medical guidance. If you’re experiencing symptoms or wish to know more about your condition, reach out to Pantai Hospital Batu Pahat at 07-433 8811 for further consultation and support.
