Yes — and this is one of the most frequently missed connections in clinical practice. Silent GERD with microaspiration is a real and common cause of recurrent lower lobe pneumonias, particularly in patients who sleep flat, consume alcohol regularly, or have a hiatus hernia. At Pulmovista Clinics, I screen every recurrent infection patient for GERD — particularly those with lower lobe predominance, nocturnal or early-morning infections, and those without any obvious respiratory predisposing factor. If GERD is confirmed on 24-hour pH monitoring, treating it often resolves the recurrent infection pattern completely.
