How High Blood Pressure Affects Blood Flow – What Colorado Springs Residents Should Know

Hypertension, the "Silent Killer"

High blood pressure, or hypertension, is often called the “silent killer” — and for good reason. It typically develops without obvious symptoms but can quietly wreak havoc on your cardiovascular system over time. At Colorado Springs Cardiology, we treat countless patients every year who are dealing with the long-term effects of high blood pressure. In a region like ours, where active outdoor living meets high elevation, understanding how hypertension affects blood flow is essential for protecting your heart health.

What Is Blood Pressure?

Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps. It’s measured in two numbers: 

  • Systolic pressure: The top number, representing the pressure when your heart beats. 
  • Diastolic pressure: The bottom number, representing the pressure when your heart rests between beats.

According to the American Heart Association (AHA), normal blood pressure is considered to be below 120/80 mmHg. Anything consistently above that may be classified as elevated or high blood pressure.

How High Blood Pressure Disrupts Blood Flow

High blood pressure affects blood flow in several critical ways, here are 3 examples:

1. Damages Arteries

Constant high pressure can stretch and damage the inner lining of your arteries, known as the endothelium. Over time, this damage leads to: 

  • Narrowed arteries from scar tissue and plaque buildup (atherosclerosis) 
  • Reduced elasticity, making it harder for arteries to dilate 
  • Increased risk for blockages that can cause heart attacks or strokes

2. Increases Resistance

When arteries narrow, your heart has to work harder to pump blood through your body. This increased workload leads to: 

  • Decreased blood flow to organs and limbs 
  • Risk of left ventricular hypertrophy (thickening of the heart’s left chamber) 
  • Higher chance of heart failure

3. Impaired Circulation to the Brain and Kidneys

Two of the most affected organs are your brain and kidneys. Inadequate blood flow can result in: 

  • Cognitive decline or vascular dementia 
  • Increased risk of ischemic stroke 
  • Kidney damage and eventual chronic kidney disease

High Altitude & Hypertension in Colorado Springs

Living at higher elevations — like Colorado Springs, which sits at over 6,000 feet above sea level — can influence how your body responds to high blood pressure. 

At altitude, your blood oxygen levels are slightly lower, which means your heart and lungs have to work harder to compensate. For individuals with hypertension, this can intensify symptoms and complications. Research from the National Center for Biotechnology Information (NCBI) indicates that acute and chronic exposure to high altitude can exacerbate blood pressure irregularities. 

That’s why it’s especially important for Colorado Springs residents to monitor and manage blood pressure closely, particularly when engaging in high-intensity activities like hiking, biking, or skiing.

Symptoms You Shouldn’t Ignore

While high blood pressure often goes unnoticed, some symptoms may signal a problem with your blood flow: 

  • Frequent headaches 
  • Shortness of breath 
  • Chest pain or tightness 
  • Blurred vision 
  • Dizziness or fainting 
  • Cold hands and feet (a sign of poor circulation) 

If you’re experiencing these symptoms regularly, it’s time to schedule an evaluation with a heart specialist.

Long-Term Consequences of Poor Blood Flow

Unchecked hypertension can lead to life-threatening complications:

Stroke

As arteries narrow and harden, the chance of clots increases. If a clot blocks blood flow to the brain, it can cause an ischemic stroke. The Centers for Disease Control and Prevention (CDC) notes that high blood pressure is the number one cause of strokes.

Heart Failure

When your heart is forced to pump against consistently high pressure, it eventually weakens. The left ventricle, in particular, can enlarge and lose efficiency, leading to congestive heart failure.

Reduced blood flow in your limbs — especially the legs — can lead to pain, numbness, and difficulty walking. PAD is common in people with hypertension and is often misdiagnosed until it becomes severe.

Aneurysm

High pressure can cause a portion of an artery to weaken and balloon out. If this aneurysm bursts, it can result in internal bleeding and potentially be fatal.

Diagnostic Tools We Use to Assess Blood Flow

At Colorado Springs Cardiology, we use several non-invasive tools to monitor your blood pressure and evaluate blood flow, including: 

  • Echocardiogram – Uses sound waves to create images of your heart 
  • Doppler ultrasound – Assesses blood flow in your veins and arteries 
  • Ankle-brachial index – Compares blood pressure in your ankle and arm to screen for PAD 
  • 24-hour blood pressure monitoring – Provides a more accurate picture of your pressure levels throughout the day

Lifestyle Tips for Managing High Blood Pressure in Colorado Springs

Living in our unique climate and terrain comes with special considerations. Here are some ways to control blood pressure and improve circulation:

1. Stay Hydrated

At high altitudes, dehydration occurs faster. Dehydration can make your heart work harder and raise blood pressure, so be sure to drink plenty of water, especially if you’re active outdoors.

2. Watch Sodium Intake

Many packaged and restaurant foods are high in sodium, which can spike your blood pressure. Stick to a heart-healthy diet like the DASH (Dietary Approaches to Stop Hypertension) diet, rich in: 

  • Fruits and vegetables 
  • Whole grains 
  • Low-fat dairy 
  • Lean proteins

More on the DASH diet from the National Heart, Lung, and Blood Institute.

3. Exercise Smart

Colorado Springs offers endless opportunities for hiking and biking, but if you have high blood pressure, avoid sudden bursts of strenuous activity. Instead: 

  • Warm up properly 
  • Pace yourself on inclines 
  • Avoid exercise at peak heat or altitude

4. Limit Alcohol & Quit Smoking

Both alcohol and tobacco use can raise blood pressure and damage your arteries. If you need help quitting, speak with one of our specialists or your primary care provider.

When to See a Cardiologist

If your blood pressure is consistently above 130/80 mmHg or if you’re experiencing symptoms of poor circulation, you should consult a cardiologist. Early intervention is key to preventing damage and restoring healthy blood flow.
