Patients with snoring symptoms after drinking alcohol are often stimulated by alcohol, causing certain congestion and swelling of the mucous membrane in the throat. At the same time, the mucous membrane of the soft palate of patients is often in a more relaxed state, which may also cause snoring symptoms. The mucous membrane in the patient’s nasal cavity may also be stimulated by alcohol, causing a certain degree of congestion and swelling, which may cause the respiratory passages to become narrow, resulting in a significant increase in respiratory resistance, and may further lead to snoring during sleep and continuous open-mouth breathing. If the patient also has obvious snoring symptoms in normal times, this snoring symptom will often be more serious after drinking alcohol, the patient needs to further do a careful and comprehensive examination of the entire upper respiratory tract to specifically analyze the cause.
