Shortness of breath: Causes, warning signs & next steps

Shortness of breath often causes immediate concern – especially when it occurs suddenly. Here you'll learn what can cause this "air hunger," how to correctly interpret warning signs, and how to use brite to check if your medication is affecting your breathing.

Better understanding shortness of breath

In short & important: What you
can do right now

If you are currently experiencing shortness of breath, these immediate measures will help to relieve your body:

Coachman's seat

Sit down, rest your arms on your knees, and loosen any tight clothing.

Stop the load

Stop all physical activity immediately.

Lip pursing

Breathe in slowly through your nose and exhale slowly against the resistance of almost closed lips.

Check

Do you also have chest pain, cold sweats, or bluish lips?

Fresh air

Open a window and ensure a supply of oxygen.
Important: If you suddenly experience shortness of breath, can barely speak in full sentences, or have pain radiating into your arm: Call emergency services (112) immediately.

What does shortness of breath really mean?

Shortness of breath (dyspnea) describes the subjective feeling of not being able to inhale deeply enough or having to exert more effort for breathing. Some describe it as a feeling of tightness in the chest, others as quickly becoming breathless even with minimal exertion. Because the heart and lungs work closely together, identifying the underlying cause is crucial for the appropriate response.

Common causes of shortness of breath

Why do you get out of breath? These are the most common causes:

Infections & Respiratory Tract (Cold, Bronchitis)

Mucus and inflamed mucous membranes impede gas exchange. If shortness of breath persists or worsens after a cold, lung involvement should be ruled out.

Cardiovascular system (signal: water retention in the legs)

Do you experience shortness of breath along with swollen ankles? This could indicate that your heart isn't pumping efficiently enough. This often first becomes apparent when climbing stairs or lying flat.

Anemia & Iron deficiency

If there are too few red blood cells, less oxygen can be transported. You feel chronically tired and are extremely short of breath even on short walks.

Stress & Psychosomatics

During periods of anxiety, we often breathe too shallowly and too quickly (hyperventilation). The feeling of not getting enough air intensifies the panic – a vicious cycle begins.

Medication as a cause

An often underestimated factor: Some medications (e.g., certain beta-blockers or painkillers) can constrict the bronchi in sensitive individuals or affect the circulatory system in such a way that shortness of breath occurs.

Is it due to your medication? Get to the bottom of it now.

Especially if you're taking multiple medications, shortness of breath can be a side effect or the result of an interaction. Don't rely on your gut feeling, but on a structured approach:

Digital medication plan : Record your entire therapy to identify patterns between medication intake and shortness of breath.
Interaction check : Check immediately whether your medications interfere with each other and affect your breathing.
Dosage reminder : Consistent intake prevents dangerous drug spikes or drops.

Warning signs – When you need to act immediately

Please do not hesitate to call for medical help if:

The shortness of breath occurs suddenly without warning.
Pressure or pain in the chest is added.
Your lips or fingernails turn bluish.
you can no longer speak because of shortness of breath .
Accompanying symptoms include cold sweats or a feeling of mortal fear.

Preparing for your doctor's appointment – ​​your checklist

To quickly narrow down the cause (heart, lungs or blood), your doctor needs precise information:

When?

Does it occur at rest or only when climbing stairs/playing sports?

Position?

Does it get worse when lying down and better when sitting?

How long?

Is the shortness of breath constant or does it occur in episodes?

Medications

Are you taking any over-the-counter medications, vitamins, or new supplements?
