Understanding Blood Pressure: Basics and Norms

What is the difference between high blood pressure and low blood pressure?
High blood pressure, medically known as hypertension, implies that the pressure of the blood in your arteries is elevated above the normal range. This condition can strain the heart, leading to arterial damage and increasing the risk of heart attack, stroke, kidney problems, and cognitive decline. Conversely, low blood pressure, known as hypotension, is when the blood pressure is so low that it causes symptoms like dizziness and fainting because organs don’t get enough blood and oxygen, especially during sudden position changes.

What is normal blood pressure?
The benchmark for normal blood pressure, typically 120/80 mmHg, is not a one-size-fits-all number. For most adults, readings below 120/80 mmHg are considered within the normal range. However, some health professionals may consider anything under 130/85 mmHg as acceptable, particularly in younger individuals. It’s important to have regular check-ups, as 'normal' can vary with age, comorbidities, and other individual health factors.

How to lower blood pressure?
To lower blood pressure, engage in regular aerobic activity — 30 minutes most days of the week can have a profound impact. A balanced diet, particularly the DASH diet (Dietary Approaches to Stop Hypertension), which is rich in fruits, vegetables, and low-fat dairy, while low in fats and cholesterol, can also reduce blood pressure. Reducing dietary salt (sodium) can have a significant, though varied, impact on lowering blood pressure. Moreover, limiting alcohol intake and quitting smoking can further improve blood pressure readings.

What causes high blood pressure?
High blood pressure can stem from an array of causes. Primary hypertension develops over time with no identifiable cause, with many elements contributing to this, including genes, physical changes, and environment. Secondary hypertension is caused by an underlying condition and appears suddenly. Conditions like obstructive sleep apnea, kidney problems, adrenal gland tumors, and certain congenital heart defects can cause secondary hypertension.

Identifying and Managing High Blood Pressure

What causes low blood pressure?
Low blood pressure can be a result of a sudden loss of blood (shock), infections, severe dehydration, or allergic reactions (anaphylaxis). Certain medications, like diuretics and other drugs that treat hypertension, can lower blood pressure, as can heart medications that do not speed up the heart rate or that even slow it down. Moreover, hormonal changes, such as those experienced during pregnancy, can also affect blood pressure.

What is hypertension?
Hypertension is diagnosed when check-ups consistently show blood pressure readings above 140/90 mmHg. It’s often tagged as the “silent killer” because it doesn’t typically cause symptoms until significant damage to the heart has been done. Hypertension requires monitoring and management, which could include lifestyle adjustments and medication. Uncontrolled, it's a significant risk factor for heart disease and stroke.

Does alcohol raise blood pressure?
Excessive alcohol consumption can lead to repeated spikes in blood pressure. Regular heavy drinking can lead to long-term hypertension, as alcohol can disrupt the sympathetic nervous system, which regulates blood pressure and heart rate. Even moderate drinking, if done regularly, can have a significant effect, particularly in sensitive individuals.

Can stress cause high blood pressure?
While stress itself is a transient cause of high blood pressure, the lifestyle habits stress can encourage, such as unhealthy eating, drinking, and smoking, can lead to sustained high blood pressure. Moreover, chronic stress may lead to adrenal gland overactivity, which can contribute to hypertension.

High Blood Pressure: Considerations and Effects

How to work out average blood pressure?
To accurately determine your average blood pressure, take readings at the same time each day, such as morning and evening, for a period, such as a week. Sit quietly before and during monitoring, and use a properly calibrated and validated device. Record all readings and calculate the average of the systolic and diastolic numbers separately.

Is high blood pressure a disability in the UK?
While high blood pressure itself is not recognized as a disability under UK law, it can lead to severe conditions like heart failure or stroke, which could be considered disabilities. Implications for disability status are based on how high blood pressure affects your ability to carry out normal day-to-day activities under the Equality Act 2010.

Does aspirin lower blood pressure?
Aspirin's role in blood pressure management is complex. It's primarily known for its blood-thinning properties, which can prevent clotting in people at risk of heart attacks and strokes. Some studies suggest that low-dose aspirin taken at night may help to lower blood pressure, but this is not a widespread treatment for hypertension and should not be taken without a doctor’s recommendation.

Does hot weather affect blood pressure?
In hot weather, blood vessels dilate, causing blood pressure to potentially drop, which is the body's way of cooling itself. However, the heat can lead to dehydration, which can increase blood pressure as the body attempts to maintain adequate fluid levels. Individuals taking blood pressure medications may be more sensitive to these changes and should stay hydrated and monitor their blood pressure.

Blood Pressure in Special Circumstances

Can you drive with high blood pressure?
Driving with high blood pressure is usually permissible as long as the condition is under control, and you're not at risk of sudden incapacitation due to the associated cardiovascular risks. Regular monitoring and medical advice are crucial if you're diagnosed with hypertension.

Is it okay to fly with high blood pressure?
Generally, flying is safe for those with high blood pressure, particularly if it is well-managed on medication. However, the stress of flying can temporarily increase blood pressure levels, so it's essential to consider this alongside any related health risks and to discuss travel plans with a healthcare provider.

Do athletes have low blood pressure?
Athletes typically exhibit lower resting blood pressure than non-athletes due to the efficiency of their cardiovascular systems. Regular intense training improves heart muscle function, which can pump a greater volume of blood with less effort, reducing the force on the arteries and thus the blood pressure.

Can statins lower blood pressure?
Statins' primary purpose is to lower cholesterol levels in the blood, but they may also have a modest effect on blood pressure. The mechanism behind this is not entirely clear, but it may be related to the drugs' ability to improve endothelial function, leading to more relaxed and dilated blood vessels.

The Importance of Carrying a Blood Pressure Medical Card

Carrying a Blood Pressure Medical Card is a sensible precaution for anyone managing hypertension or hypotension. For those with high blood pressure, a medical card offers peace of mind, ensuring that in the event of a medical situation where the individual might not be able to communicate effectively, the attending medical professionals are immediately aware of the condition. This is crucial for prompt and accurate treatment, as hypertension can affect how certain emergency measures are administered.

Similarly, a Blood Pressure Medical Card for individuals with low blood pressure can be just as critical. It can alert first responders to the possibility of hypotensive episodes which might be causing symptoms like dizziness or fainting, allowing for more appropriate and swift care.

These cards are not just for emergencies; they can be equally useful in everyday situations, such as visits to new healthcare providers or when travelling. Having all the essential information on a card streamlines the process of receiving care.

Moreover, our Blood Pressure Medical Cards are designed to be durable and easily accessible. Made from biodegradable plastic, they are an environmentally conscious choice that aligns with the growing need for sustainability. The size of a credit card, they fit conveniently into a wallet, purse, or pocket, which means they are easy to carry at all times.

Ultimately, a Blood Pressure Medical Card is a simple, yet effective tool in managing one's health. It's a small step that can have a significant impact on the quality of care you receive in a medical situation, providing essential information that can speak for you when you might not be able to.
