Drinking baking soda for stomach acidity can relieve stomach discomfort, but baking soda may irritate the gastric mucosa when used improperly due to its strong alkalinity. Drinking baking soda in moderation can play a role in neutralizing stomach acid and balancing the acid-base balance. If the symptoms of stomach acid are relatively mild, you can drink some soda to relieve acid reflux, heartburn and other symptoms. However, human gastric fluid is constantly increasing, if the patient’s stomach acid secretion is too much, this situation does not all rely on drinking baking soda to improve. If the patient is also accompanied by gastric ulcer or gastric perforation, a large amount of carbon dioxide produced by drinking baking soda will stimulate the gastric mucosa, and even lead to gastric perforation and so on, it is recommended that the patient should not take it privately, so as not to cause adverse consequences . If the patient has stomach acidity, it is recommended to go to the hospital in time for examination, to clarify the cause of the disease, for treatment, and not to take medication privately, so as not to cause adverse consequences.
