Low blood pressure, or hypotension, is a medical condition in which the blood pressure readings are consistently lower than the normal range. Blood pressure assesses the strength that blood exerts on the walls of arteries while moving through the body’s circulatory system. Normal blood pressure readings are around 120/80 mmHg, and low blood pressure is considered anything below 90/60 mmHg.
While low blood pressure may not seem like a significant issue, it can be a sign of an underlying condition that requires medical attention. In this article, we’ll cover the various causes of low blood pressure and how to manage this condition effectively.
What Causes Low Blood Pressure?
Low blood pressure can be caused by a variety of factors, including:
- Dehydration: When the body does not have enough fluid, it can cause a drop in blood pressure. This is why drinking enough water each day is essential to stay hydrated.
- Certain Medications: Some medications, such as blood pressure medication, can lower blood pressure levels. Medications that treat depression, anxiety, and heart conditions can also cause low blood pressure.
- Heart Problems: Cardiac problems, such as heart valve problems, heart attack, and heart failure, can result in low blood pressure.
- Pregnancy: Hormonal changes and increased blood volume during pregnancy can cause low blood pressure.
- Endocrine Disorders: Endocrine disorders like hypothyroidism and adrenal gland problems can cause low blood pressure.
- Anaemia: When there is a lack of red blood cells in the body, it can cause low blood pressure.
- Blood Loss: Blood loss from a serious injury or surgery can result in low blood pressure.
- Nervous System Disorders: Nervous system disorders, such as Parkinson’s disease, can cause low blood pressure.
- Severe infections: such as sepsis, can result in low blood pressure.
- Dietary Changes: Rapid changes in diet, such as reducing salt or carbohydrate intake, can cause low blood pressure.
- Ageing: As we age, our blood pressure tends to decrease naturally.
What are the Symptoms of Low Blood Pressure?
Low blood pressure can cause a variety of symptoms, including:
- Dizziness
- Fainting
- Blurred vision
- Fatigue
- Nausea
- Chest pain
- Rapid, shallow breathing
- Cold, clammy skin
- Rapid or weak pulse
If you experience these symptoms, seeking medical attention immediately is important.
How is Diagnosed?
Low blood pressure can be diagnosed through a physical examination and a series of tests, including:
- Blood Tests: Blood tests can help determine if any underlying medical conditions are causing low blood pressure.
- Electrocardiogram (ECG): ECG can help determine if any heart problems are causing low blood pressure.
- Echocardiogram: An echocardiogram is a test that uses sound waves to create a detailed image of the heart. It can help determine if any structural problems with the heart are causing low blood pressure.
- Tilt Table Test: The test involves tilting a person’s body to various angles while monitoring their blood pressure and heart rate. This test is used to diagnose postural hypotension, a type of low blood pressure caused by a sudden change in position.
- Holter Monitor Test: Holter monitor test involves wearing a small device that continuously records your heart rate and blood pressure for 24 to 48 hours. This test is used to identify any fluctuations in blood pressure and heart rate.
- Ultrasound: Ultrasound is a non-invasive test that uses high-frequency sound waves to produce images of internal organs. It can help diagnose any underlying issues with the blood vessels that may be causing low blood pressure.
How is Treated?
The treatment for low blood pressure depends on the underlying cause. Some common treatments include:
- Lifestyle Changes: Changing your diet, such as increasing your fluid and salt intake, can help manage low blood pressure.
- Medications: In some cases, medications can be used to treat low blood pressure. This may include medications to raise blood pressure, such as fludrocortisone, or medications to treat the underlying cause of low blood pressure.
- Physical Therapy: Physical therapy can help improve circulation and reduce the symptoms of low blood pressure.
- Surgery: In severe cases, surgery may be required to correct any underlying medical conditions causing low blood pressure.
