Understanding Blood Pressure Problems: High and Low Explained Simply

Blood pressure matters more than most people realise. When it’s too high or too low, it can cause serious issues. Some people have no symptoms at all, while others feel faint or tired. Knowing where your numbers sit—and having the right information on hand in an emergency—can make a real difference.

What Is High Blood Pressure and Why It’s a Health Risk

High blood pressure (hypertension) means the pressure inside your arteries is too strong. It’s measured using two numbers: the top one is the pressure when your heart beats, and the bottom one is when your heart rests. A reading of 140/90 mmHg or higher is classed as high.

If it’s left untreated, high blood pressure can damage your heart, brain, and kidneys over time. It increases the risk of stroke, heart attack, and other long-term health conditions.

High Blood Pressure Risk Factors You Should Know About

Anyone can get high blood pressure, but it’s more likely if:

• you’re over 65

• it runs in your family

• you’re overweight

• you eat too much salt or not enough fruit and veg

• you drink more than the recommended amount of alcohol

• you don’t get enough exercise

• you feel under constant stress

Common Symptoms of High Blood Pressure and What to Watch For

Most people with high blood pressure don’t feel any different, which is why regular checks matter. When symptoms do show up, they might include:

• headaches

• nosebleeds

• shortness of breath

These signs often don’t appear until the condition has become severe.

How to Lower High Blood Pressure with Lifestyle and Medication

If your blood pressure is high, small changes can help. Many people are advised to:

• eat more fresh food and less salt

• lose weight

• cut down on alcohol

• stay active most days

If that’s not enough, doctors may prescribe medicine. This could include ACE inhibitors, beta blockers, calcium channel blockers or diuretics, depending on what suits you best.

What Is Low Blood Pressure and Why It Can Be Dangerous

Low blood pressure (hypotension) means your numbers are too low—generally below 90/60 mmHg. It’s not as common as high blood pressure, but it can still cause problems. If blood doesn’t reach your brain and organs properly, you might feel dizzy, faint, or even collapse.

Low Blood Pressure Risk Factors That May Affect You

Some things can make low blood pressure more likely. These include:

• getting older (especially if you feel faint when you stand up quickly)

• taking certain medications

• having conditions like diabetes or heart problems

• dehydration

• blood loss from injury or illness

Signs and Symptoms of Low Blood Pressure That Shouldn’t Be Ignored

If your blood pressure is too low, you might notice:

• dizziness or feeling lightheaded

• fainting

• blurred vision

• nausea

• feeling tired or weak

These symptoms can come and go or appear suddenly, especially when changing position.

How to Raise Low Blood Pressure Safely and Effectively

The right approach depends on what’s causing the problem. Some general tips include:

• drinking more fluids

• adding more salt to meals (only if advised by a doctor)

• wearing compression stockings

• taking medicine, if needed, to stabilise your blood pressure

Always speak to a healthcare provider before making big changes.

Why People with Blood Pressure Conditions Should Carry a Medical ID Card

If you live with either high or low blood pressure, carrying a medical card can be a smart move. In an emergency, it gives doctors or paramedics clear information fast. This can help them make safer choices and give the right treatment more quickly.

Benefits of Having a Blood Pressure Medical Card in an Emergency

There are a few reasons why a medical ID card is worth having:

• It explains your condition and medication at a glance

• It can include emergency contacts

• It gives peace of mind when you’re out and about

Whether you’re at home, on holiday, or just doing the shopping, having your card in your wallet or purse means you’re prepared if something happens.
