The treatment of gastritis, besides dietary adjustments, mainly involves drug therapy. In terms of diet, it is recommended that patients adopt a light, easily digestible diet, eat regularly, avoid overeating, and avoid consuming pickled or spicy foods and substances that harm the gastrointestinal mucosa, such as alcohol and coffee. For medication, one can choose drugs that protect the stomach or promote gastrointestinal motility. Of course, one can also choose traditional Chinese medicine formulations that protect the stomach. The treatment course is usually between two to four weeks, but regular dietary adjustments and rest are fundamental. Clinically, gastritis is quite common and generally refers to stomach disorders caused by various inflammations, with Helicobacter pylori infection being the most common cause. Therefore, for patients with gastritis, it is recommended to further screen for Helicobacter pylori. If Helicobacter pylori is found positive, in addition to protecting the stomach, treatment to eradicate Helicobacter pylori is necessary, generally involving four types of medications. The diagnosis of gastritis mainly relies on gastroscopy and pathology. Patients typically present with abdominal discomfort or weight loss, and gastroscopy shows inflammatory changes in the stomach. Therefore, it is generally recommended that patients undergo a gastroscopy. (Please take medication under the guidance of a professional physician.)
