What causes shortness of breath but normal oxygen levels?

Feeling short of breath (dyspnea) with normal oxygen saturation (SpO2) happens because breathing involves more than just oxygen; conditions affecting your heart (heart failure, anemia), lungs (stiffness, asthma), fitness, or even anxiety can make you feel breathless, as the oxygen sensor (SpO2) doesn't detect problems with blood flow or oxygen delivery to tissues. It's a sign the body's complex breathing control system is signaling distress, even if there's enough oxygen in the blood.

Why does prednisone cause shortness of breath?

While prednisone usually helps breathing by reducing inflammation, it can rarely cause shortness of breath via fluid buildup (pulmonary edema), allergic reactions (with swelling/hives), or by affecting the brain's breathing center, though the latter is less common and often linked to dose/timing, potentially stimulating breathing or causing hyperventilation. Always report new shortness of breath to your doctor, as it could signal serious issues like fluid retention or a severe allergic response.

Yes, sinus issues like inflammation, congestion, and excess mucus (postnasal drip) can absolutely cause shortness of breath by blocking nasal passages, forcing mouth breathing, irritating airways with drip, triggering coughing, and worsening related conditions like asthma, making breathing feel difficult, tight, or shallow. While sinus issues might not directly cause asthma-level breathlessness, they create physical obstructions and inflammation that significantly impact breathing quality and comfort, often leading to feelings of breathlessness or fatigue.
