Understanding Blood Pressure Readings
Blood pressure is an important health marker that can provide insight into the risk of certain conditions. But what does a reading of blood pressure 93 actually mean? Is it too low and cause for concern?
What is Considered Low Blood Pressure?
Blood pressure is recorded as two numbers, systolic pressure (top number) over diastolic pressure (bottom number). Normal blood pressure ranges are:
- Normal: Less than 120/80 mmHg
- Elevated: 120-129/Less than 80 mmHg
- Stage 1 Hypertension: 130-139/80-89 mmHg
- Stage 2 Hypertension: 140/90 mmHg or higher
Low blood pressure, also called hypotension, is generally classified as:
- Normal/healthy: 90/60 mmHg or higher
- Mild hypotension: 85-89/55-59 mmHg
- Moderate hypotension: 80-84/50-54 mmHg
- Severe hypotension: Below 80/below 50 mmHg
Evaluating a Blood Pressure of 93
A blood pressure reading of 93 is the systolic number, which means the diastolic reading is unknown. But in general, a systolic pressure of 93 mmHg would fall into the range of moderate hypotension.
Causes and Contributing Factors
There are many potential causes of low blood pressure, including:
Medical Causes
- Dehydration
- Pregnancy
- Heart conditions
- Endocrine problems
- Nutrient deficiencies
- Severe infection (sepsis)
- Allergic reactions (anaphylaxis)
- Blood loss/hemorrhage
Medications
- Diuretics
- Blood pressure medications
- Antidepressants
- Alpha blockers
- Nitrates
- Morphine
Other Factors
- Prolonged bed rest
- Heat exposure
- Pilot or astronaut in a high-performance jet
- Autonomic neuropathy
- Aging
- Fighting infection
Symptoms and Health Risks
Many people with low blood pressure are asymptomatic. But moderate to severe hypotension can come with symptoms like:
- Dizziness
- Fainting (syncope)
- Vision changes
- Nausea
- Fatigue
- Depression
- Blurry vision
- Rapid, shallow breathing
Risks and Complications
If left untreated, continuing issues with low blood pressure can negatively impact health in various ways:
- Chronic fatigue and weakness
- Cognitive impairment with poor concentration, confusion and memory loss
- Increased risk of falls especially among seniors
- Reduced oxygen delivery to the heart, triggering angina or arrhythmias
- Worse outcomes for those with sepsis, diabetes and heart disease
Getting Evaluated and Diagnosed
Since blood pressure can fluctuate, repeat readings on different days can help diagnose hypotension. A doctor will also review medications, symptoms, perform a physical exam, and may order additional tests to determine any underlying condition causing low blood pressure.
Blood Tests
Blood tests help check for nutritional deficiencies, dehydration, diabetes, thyroid disorders, adrenal gland problems and more.
Orthostatic Blood Pressure Test
This test measures blood pressure while lying down, then immediately after standing up. A significant drop may indicate certain forms of hypotension.
Echocardiogram
An imaging test that uses ultrasound waves to evaluate how well the heart pumps blood to help detect causes like heart valve abnormalities or dysfunction.
Tilt Table Test
This special test has you lie flat on an exam table before the table is quickly tilted to an upright position. Blood pressure and heart rate changes are then monitored over time to aid diagnosis.
Treatments and Lifestyle Tips
Treatments for blood pressure readings of 93/low hypotension aim to raise blood pressure to safer levels and prevent complications. This may include:
Treating Underlying Causes
Addressing contributing factors when possible is key, whether stopping problematic medications, reversing dehydration with fluids, managing sepsis or diabetes, etc.
Raising Blood Volume
Increasing fluid and salt intake from foods/drinks or possibly IV saline solutions expands blood volume. Compression stockings and small frequent meals also help.
Medications
Midodrine helps raise blood pressure levels by constricting blood vessels. Other meds like corticosteroids or vasopressors may also be used.
Lifestyle Changes
- Hydrate frequently and replenish electrolytes.
- Eat more frequent small meals.
- Limit or avoid alcohol and cigarettes.
- Slowly change positions.
- Engage muscles before standing by stretching.
- Sleep with head slightly elevated.
- Exercise regularly as tolerated.
Implementing healthy lifestyle strategies, individualized treatment plans, and monitoring hypotension can help minimize symptoms and associated risks.
FAQs
Is a blood pressure of 93 dangerously low?
A reading of 93 mmHg systolic blood pressure falls into the moderately hypotension range. While not dangerously low, blood pressure in the 80s or below increases health risks like weakness, fainting, and inadequate oxygen circulation.
What causes blood pressure to be 93?
Potential causes of low BP around 93 mmHg include dehydration, heart conditions, diabetes, thyroid disorders, certain nutrient deficiencies, blood loss from injury, sepsis infection, side effects of some medications, and more.
Can I drive if my blood pressure is 93?
Driving with moderate hypotension like a pressure around 93/50 mmHg can be unsafe, especially if you experience lightheadedness, dizziness or blurred vision. It's best not to drive until BP and symptoms are better controlled.
What can I do to improve blood pressure of 93?
Treatment involves identifying and addressing underlying causes when possible. Other ways to help increase BP of 93 mmHg include staying hydrated, consuming more sodium, wearing compression stockings, raising the head of your bed, avoiding problematic medications, and following your doctor's individualized treatment plan.
