Can I drink a bottle of beer if I have phlegm but no sore throat and can't cough it up?

In general, individuals who have phlegm that is difficult to cough up without a sore throat should not drink a bottle of beer, as it may lead to rapid progression of their condition. The detailed explanation is as follows:

Difficulty in coughing up phlegm without throat pain may be related to upper respiratory tract infections, chronic pharyngitis, or other causes. When the mucous membranes of the throat are invaded by pathogens, patients may experience discomfort in the throat area. Beer contains alcohol, and drinking it during illness may irritate the throat, potentially accelerating disease progression. Therefore, patients experiencing difficulty in expelling phlegm without throat pain are advised against consuming beer. During the course of illness, patients should actively cooperate with doctors to identify the exact cause and receive standardized treatment according to medical advice based on the underlying cause, so as to prevent ongoing disease progression from posing a threat to health.

Before the exact cause is fully determined, patients should not self-medicate. If medication is needed, they should consult a doctor in advance to avoid improper drug use that could cause further harm to their health.
