Generally, occasional vomiting will not cause weight loss, but if it exists frequently for a long period of time, or accompanied by gastritis, gastric ulcer, gastroesophageal reflux, or even gastrointestinal tract tumors and other related conditions, or other organic diseases, it may lead to weight loss, so this situation requires a comprehensive analysis and judgment, rather than purely through a certain symptom to determine whether weight loss will occur. It can be combined with the recent dietary habits, as well as other medical history, symptoms, signs, or gastroscopy, Helicobacter pylori, abdominal fluoroscopy and other related examinations, comprehensive assessment, targeted treatment, which is a more prudent way, you can carry out fasting, infusion, and other targeted treatment, but also with rabeprazole sodium enteric-coated tablets, moxapride tablets and other related medications to alleviate the situation.
