Can Drinking Excess Alcohol Cause Coughing?

My brother has been drinking beer since he was a teenager. He is now in his early 50's. He tends to drink 3 to 4 cans of beer almost every day. He gets the large cans. Anyway, he coughs most every day. It's annoying to me to hear this cough. I don't think it's healthy to be drinking beer. I want him to be healthy and when I ask about the cough he says it's from his sinuses. I always tell him to get a yearly check up but he doesn't do so. I am just concerned. Can fluid build up in him and make him cough? Thanks.
