Same here. That's why I am going to see a GI doctor to see if I have reflux or silent reflux. I always have to do Airway clearance before lunch and dinner, so that mucus does not come out after eating.

Productive coughs after eating seem to come with the territory. Since I've been practicing almost complete clearance, productive coughs after eating are less of an issue. The downside is that it's time consuming and somewhat exhausting. The upside is that I cough less during the day including after meals.

What do I mean by near complete clearance? Until mucus turns the faintest color of pale yellow to white or clear. More often pale pale yellow and small amount, 1/2 penny's worth! My 2 cent$

I’ve noticed the same thing. Now, after I eat, I drink a glass of water and gargle. My theory is the small bits of food get lodge in the bronchial tubes and coughing is a way to expel these particles.
I also have diverticulosis, which is the same concept. I’m told no nuts or seeds bc they get caught in the diverticuli. Lately I’ve just been eating soft foods bc they are easier to swallow and digest.
Hope this helps.
Good luck!

I too have had this happen often where I need to cough very soon after eating, even though I’ve done my airway clearance earlier. I go sit in my chair and relax after eating and all of a sudden things feel loosened up and ready to come out. I don’t have reflux, but I still don’t like coughing after a meal.
