Regurgitation is usually caused by laryngitis, food accumulation, pyloric obstruction, acute gastritis, etc. Women should be alert to pregnancy. Many people suffer from laryngitis, and the mucous membrane of the throat of these people is relatively sensitive, which will cause irritation to the throat when eating, and therefore will be more likely to regurgitate. The accumulation of food is caused by poor digestion and the inability to empty the stomach in a timely manner. A person with accumulation of food will have a large amount of food in the stomach, and the digestive system will become more burdened when food is ingested, so regurgitation will occur. In the case of pyloric obstruction, food is not discharged through the pylorus so it is retained in the stomach. When eating, food enters the stomach, which leads to more severe internal pressure in the stomach, and regurgitation occurs. During an attack of acute gastroenteritis, food intake can cause stimulation of the stomach lining due to inflammation of the gastric mucosa, resulting in spasmodic contraction of the stomach lining, which can lead to regurgitation. Women who experience regurgitation while eating along with symptoms such as cessation of menstruation, loss of appetite, and drowsiness should be alerted to pregnancy.
