Low Blood Pressure

13 min read

Low blood pressure, also known as hypotension, is a condition in which the pressure of the blood in the arteries is abnormally low. It is usually defined as a systolic pressure of less than 90 mmHg and/or a diastolic pressure of less than 60 mmHg. Low blood pressure can be caused by a variety of medical conditions, including dehydration, heart problems, and endocrine disorders. It can also be caused by certain medications, such as diuretics and beta-blockers.

Causes of Low Blood Pressure

Low blood pressure can be caused by a variety of medical conditions, including dehydration, heart problems, and endocrine disorders. It can also be caused by certain medications, such as diuretics and beta-blockers. Other causes of low blood pressure include pregnancy, anemia, and certain neurological disorders.

Diagnosis of Low Blood Pressure

Low blood pressure is usually diagnosed by taking a patient's blood pressure. If the systolic pressure is below 90 mmHg and/or the diastolic pressure is below 60 mmHg, then the patient is considered to have low blood pressure. Other tests, such as blood tests and imaging studies, may be used to help diagnose the underlying cause of the low blood pressure.

Complications of Low Blood Pressure

Low blood pressure can lead to a variety of complications, including dizziness, fainting, and fatigue. It can also lead to an increased risk of falls and injuries. In severe cases, low blood pressure can lead to shock, which can be life-threatening.

When to See a Doctor

Causes

Dehydration

Dehydration is one of the most common causes of low blood pressure. When the body is dehydrated, it does not have enough fluids to maintain normal blood pressure. This can lead to a decrease in blood pressure, which can cause dizziness, fatigue, and other symptoms.

Medications

Certain medications can cause low blood pressure. These include diuretics, beta blockers, and calcium channel blockers. If you are taking any of these medications, it is important to talk to your doctor about the potential side effects.

Heart Disease

Heart disease can also cause low blood pressure. If the heart is not able to pump enough blood, it can lead to a decrease in blood pressure. This can cause symptoms such as dizziness, fatigue, and shortness of breath.

Pregnancy

Pregnancy can also cause low blood pressure. During pregnancy, the body produces more blood, which can lead to a decrease in blood pressure. This can cause symptoms such as dizziness, fatigue, and shortness of breath.

Endocrine Disorders

Endocrine disorders, such as diabetes and thyroid disorders, can also cause low blood pressure. These disorders can affect the body's ability to regulate blood pressure, which can lead to a decrease in blood pressure.

Age

As people age, their bodies become less efficient at regulating blood pressure. This can lead to a decrease in blood pressure, which can cause symptoms such as dizziness, fatigue, and shortness of breath.

Conclusion

Low blood pressure can be caused by a variety of factors, including dehydration, medications, heart disease, pregnancy, endocrine disorders, and age. It is important to understand the causes of low blood pressure in order to prevent it from occurring.

Getting a Diagnosis

Physical Exam

The first step in diagnosing low blood pressure is a physical exam. During the exam, the doctor will take your blood pressure and check your pulse. They may also check your temperature, breathing rate, and other vital signs. The doctor may also ask questions about your medical history and any medications you are taking.

Blood Tests

Blood tests can be used to check for underlying medical conditions that may be causing your low blood pressure. These tests may include a complete blood count, electrolyte tests, and tests to check for kidney and liver function. Your doctor may also order tests to check for anemia, diabetes, and other conditions.

Imaging Tests

Imaging tests such as an X-ray, CT scan, or MRI may be used to check for any abnormalities in the heart, lungs, or other organs that may be causing your low blood pressure. These tests can also help to rule out any other potential causes of your symptoms.

Tilt Table Test

The tilt table test is a procedure used to diagnose low blood pressure. During the test, you will be placed on a table that is tilted at various angles. This helps to measure your blood pressure and heart rate in different positions. The test can help to diagnose conditions such as postural hypotension, which is a type of low blood pressure that occurs when you stand up.

Conclusion

Low blood pressure can be a serious medical condition, but it can be diagnosed and treated. If you are experiencing symptoms of low blood pressure, it is important to see your doctor for a proper diagnosis. Your doctor may use a combination of physical exams, blood tests, imaging tests, and the tilt table test to diagnose the cause of your low blood pressure.

Drugs & Medications

Types of Drugs for Low Blood Pressure

The type of drug used to treat low blood pressure depends on the underlying cause. Commonly prescribed drugs include:

  • Diuretics: These drugs help the body get rid of excess fluid, which can help reduce blood pressure.
  • Alpha blockers: These drugs help relax the blood vessels, which can help reduce blood pressure.
  • Beta blockers: These drugs help slow the heart rate, which can help reduce blood pressure.
  • ACE inhibitors: These drugs help reduce the production of a hormone that can cause blood vessels to constrict, which can help reduce blood pressure.
  • Calcium channel blockers: These drugs help relax the blood vessels, which can help reduce blood pressure.

Side Effects of Drugs for Low Blood Pressure

Like all medications, drugs for low blood pressure can cause side effects. Common side effects include dizziness, lightheadedness, nausea, and fatigue. If you experience any of these side effects, contact your doctor immediately.
