Pulmonary Hypertension: When Shortness of Breath Is More Than Just Spring Fatigue

When it gets warmer during spring, many people feel tired, dizzy, or short of breath. But sometimes, these symptoms are more than just seasonal sluggishness. Pulmonary arterial hypertension (PAH) is a rare form of Pulmonary Hypertension, and a progressive disease that affects the blood vessels in the lungs and can lead to serious heart problems if left untreated. The tricky part? Early symptoms often seem harmless.

What Is Pulmonary Arterial Hypertension?

PAH occurs when the blood vessels in the lungs narrow, causing increased pressure in the pulmonary arteries. This puts an immense strain on the right side of the heart and can cause permanent damage over time. Between 48 and 55 people per million are affected - women more often than men. Common warning signs include shortness of breath, fatigue, dizziness, a racing heart, or even fainting. Chest pain and swelling in the legs (edema) can also be red flags.

Common Symptoms of PAH: 

  • Shortness of breath 
  • Fatigue
  • Rapid heartbeat
  • Swelling in legs or ankles (edema) 
  • Chest pain
  • Blue lips or fingers
  • Dizziness or fainting

Vague Symptoms, Serious Risk

Because these symptoms are often non-specific, PAH is often diagnosed late. Without timely treatment, PAH can progress rapidly and may lead to right-sided heart failure. If you are experiencing ongoing breathlessness, constant fatigue, or unexplained circulation issues, it's important to seek medical advice. Early diagnosis can greatly improve treatment outcomes and help maintain quality of life.

Specialized Centers for Accurate Diagnosis

As PAH is rare and complex, experts recommend getting checked at specialized pulmonary hypertension centers.  Specialists at these centers can use echocardiography (a heart ultrasound) and pulmonary artery pressure tests inside the lungs help confirm the diagnosis. Once confirmed, patients can start targeted therapies, which may include medication, physical therapy, and regular check-ups.

Family Members Need Support Too

A recent European survey shows that pulmonary hypertension is not only a physical burden but also takes a significant emotional and social toll on both - patients and their loved ones. In addition to everyday challenges, such as traveling or participating in leisure activities, there’s a strong need for psychological support.
Support services such as counseling and peer groups can offer much-needed relief. Visit to lungenhochdruck.at/en/ learn more and explore resources offered by patient organizations.

Do you know the signs?
PH Symptoms are often mistaken for signs of other illnesses.
