Blood pressure measures the force of blood pushing against the walls of your arteries as your heart pumps it throughout your body. This measurement is expressed as two numbers: systolic pressure and diastolic pressure. The systolic pressure, the top number, indicates the pressure in your arteries when your heart beats and contracts, pushing blood out. The diastolic pressure, the bottom number, represents the pressure in your arteries when your heart rests between beats and refills with blood. Both values are important indicators of your overall cardiovascular health.
Understanding 85/58 Blood Pressure
A blood pressure reading of 85/58 mmHg (millimeters of mercury) is considered low blood pressure, medically known as hypotension. A normal blood pressure reading for adults is considered to be below 120/80 mmHg. A reading below 90/60 mmHg falls into the low blood pressure category.
While some individuals may naturally have lower blood pressure without any adverse effects, a reading of 85/58 mmHg is below the commonly accepted normal range. It is considered low and warrants attention, especially if accompanied by symptoms.
Common Symptoms of Low Blood Pressure
Many individuals with low blood pressure may not experience any symptoms. However, when symptoms do occur, they can include feelings of lightheadedness or dizziness. Some people might also experience fainting, blurred or distorted vision, or a general feeling of weakness.
Other common symptoms include nausea, fatigue, and difficulty concentrating. Low blood pressure can lead to cold, clammy, or pale skin, and rapid, shallow breathing. If you frequently experience these symptoms, especially if they are new or sudden, you should seek medical advice.
Potential Causes of Low Blood Pressure
Various factors can contribute to low blood pressure. Dehydration, a common cause, reduces blood volume, which can lead to a drop in pressure. Certain medications are also known to lower blood pressure, including diuretics, beta-blockers, drugs for erectile dysfunction, some antidepressants, and medications used to treat Parkinson’s disease.
Underlying medical conditions can also play a role. Heart problems, such as an abnormally slow heart rate (bradycardia) or heart failure, can affect the heart’s ability to pump enough blood effectively. Endocrine problems, like an underactive thyroid, can disrupt the body’s hormone regulation, influencing blood pressure.
Severe infections, such as sepsis, or severe allergic reactions like anaphylaxis, can lead to a drop in blood pressure. Nutritional deficiencies, such as anemia, can also contribute to low blood pressure. Prolonged bed rest or even prolonged standing can also contribute to lower blood pressure.
When to Seek Medical Advice
If you consistently have a blood pressure reading of 85/58 mmHg, particularly if you are experiencing symptoms, you should consult a healthcare professional. Even if you do not have symptoms, a persistent low reading should be discussed with your doctor during routine check-ups. It is especially important to seek immediate medical attention if you experience severe symptoms such as confusion, a weak and rapid pulse, or rapid, shallow breathing, as these could indicate a serious underlying issue like shock.
Your doctor will likely conduct an examination to determine the cause of your low blood pressure. They may ask about your medical history, current medications, and any other symptoms you are experiencing. Depending on the cause, recommendations might include lifestyle adjustments, such as increasing fluid intake or dietary changes, or adjusting existing medications.
