Due to the accumulation of too much food inside the stomach, the level of the stomach is higher when lying down, and the performance of wanting to vomit will easily appear. Chronic pharyngitis is more common in daily life, due to inflammation in the throat area resulting in increased secretions, which can cause foreign body sensation, itching and other performance in the throat area. When a person is lying down, there will be obvious sticky secretions on the back wall of the pharynx, which cannot be coughed up or swallowed, causing irritation to the throat, which will lead to nausea and vomiting.
