Acid in the stomach without dinner may be related to overproduction of stomach acid. Not eating dinner at night will cause the stomach to remain empty for a long time, and this will then stimulate the secretion of stomach acid, which will lead to acid reflux, belching (burping) and other symptoms. In addition, not eating dinner for a long time may also cause stomach diseases. Because not eating will stimulate the secretion of gastric acid, but there is no food in the stomach for its decomposition, it will corrode the gastric mucosa, and then cause gastrointestinal diseases such as gastric ulcers, gastritis and so on. In this case, it is recommended to eat some light and easy to digest food, such as millet porridge, rice soup and so on. Oral medication to protect the gastric mucosa, such as aluminum sulfate, should be taken as prescribed by the doctor. If the symptoms persist and are accompanied by other discomforts (such as stomach pain, vomiting, etc.), it is recommended to go to the hospital in time. Finally, we remind you that there are many hazards of not eating, such as gastric disease, cholecystitis, malnutrition and so on. Therefore, it is recommended that everyone must eat on time, so as to be conducive to good health.
