If vomiting occurs after consuming plums, you can stop consuming plums or reduce the consumption of plums. If there are other symptoms, such as abdominal pain, diarrhea, etc., you can take some medicines to relieve the symptom under the guidance of a professional physician or pharmacist, commonly used medicines include omeprazole, lansoprazole and other medicines that can inhibit the secretion of gastric acid. Plums contain more ellagic acid, which can promote the secretion of gastric acid and gastric digestive enzymes, and consuming a moderate amount of plums can help with food digestion. However, if too many plums are consumed, the ellagic acid may irritate the mucous membrane of the gastrointestinal tract, leading to an increase in the secretion of gastric acid, which is prone to abdominal pain, diarrhea, nausea and vomiting and other symptoms. Therefore, it is not recommended to consume too many plums in an empty stomach state. If you are a patient with excessive stomach acid, chronic gastritis, gastric ulcer, it is also not recommended to consume too much plums and prunes and other fruits rich in organic acids, so as not to cause stomach discomfort and aggravate the condition.
