Snoring is mostly seen in obese patients, but also in people with nasal polyps, bronchial asthma, chronic obstructive pulmonary disease, hypertension, coronary heart disease and other chronic underlying diseases. Once snoring can be taken in two ways: 1. Ask the ENT doctor to take a closer look at the pharynx to see if there are enlarged glands, enlarged tonsils, and enlarged uvula causing narrowing of the airway, which leads to snoring. Snoring is aggravated after drinking alcohol and catching a cold. It is recommended that patients lie on their sides and avoid the supine position as much as possible in order to make the airway open and the uvula can not fall back to keep the respiratory tract open and alleviate the symptoms of snoring.2. Please ask respiratory physicians to conduct arterial blood gas analysis to find out whether there is any change in blood oxygen saturation and carbon dioxide after snoring. You can purchase a non-invasive ventilator to wear at night for a long time to improve airway patency through two-way ventilation and reduce the symptoms of snoring. If snoring is very severe, the ENT surgeon may also recommend surgery to open the airway and reduce the symptoms of snoring.
