The symptoms of white froth at the mouth are mainly caused by gastrointestinal flocculation, because the symptoms of gastrointestinal flocculation lead to functional disorders of the digestive system and dysbiosis, which can cause excessive spoilage and fermentation of harmful bacteria and food, resulting in a large amount of belching. As the peristalsis slows down, belching accumulates in the stomach and reacts with gastric acid. During gastric emptying, the gastric acid accompanying the belching component refluxes into the esophagus and mouth, resulting in this condition and white foam at the mouth. If the patient suffers from convulsions, syncope, weakness and other adverse symptoms, he or she needs to go to the hospital as soon as possible for medical examination to confirm the specific cause of the disease and then carry out symptomatic treatment.
