What are the causes of acid reflux in gastritis?

　　In general, the causes of acid reflux associated with gastritis may include improper diet, psychological factors, Helicobacter pylori infection, gastroesophageal reflux disease (GERD), and bile reflux gastritis. Symptomatic management usually involves general treatments and medication. If symptoms are severe, timely medical consultation is recommended, following the doctor's instructions for treatment. A detailed explanation is as follows:

　　1. Improper Diet

　　Frequently consuming spicy, greasy, or sweet foods, or drinking large amounts of alcohol can directly irritate the gastric mucosa, leading to excessive secretion of gastric acid and resulting in acid reflux, which may be accompanied by symptoms such as stomach pain, bloating, nausea, and discomfort. It is recommended to adjust dietary habits, avoid excessive intake of irritating foods, and consume bland, easily digestible foods in moderation, such as millet porridge or pumpkin porridge.

　　2. Psychological Factors

　　Prolonged anxiety, stress, and other negative emotions can affect nervous system regulation, causing disordered gastric acid secretion and resulting in acid reflux, which may be accompanied by symptoms such as insomnia, vivid dreams, and palpitations. It is recommended to maintain a positive mindset, avoid excessive anxiety and tension, and seek psychological counseling or treatment when necessary.

　　3. Helicobacter pylori Infection

　　Infection with Helicobacter pylori may occur through consumption of contaminated water or food. Once present in the gastric mucosa, Helicobacter pylori multiply and release toxins and enzymes that damage the gastric mucosal barrier, triggering inflammatory responses and stimulating excessive gastric acid secretion from gastric wall cells. Symptoms may include stomach pain, bloating, and nausea. Patients should follow medical advice to undergo antibiotic combination therapy to eradicate Helicobacter pylori, using medications such as amoxicillin capsules, clarithromycin tablets, and omeprazole enteric-coated capsules.

　　4. Gastroesophageal Reflux

　　Gastroesophageal reflux is associated with dysfunction of the lower esophageal sphincter. When the sphincter's tone decreases or it relaxes, gastric acid and stomach contents can flow back into the esophagus, damaging the esophageal mucosa. Symptoms may include retrosternal burning sensation, belching, and coughing. It is recommended to use medications such as lansoprazole tablets, famotidine tablets, and domperidone tablets under medical guidance for treatment.

　　5. Bile Reflux Gastritis

　　Dysfunction of the pyloric sphincter or previous pyloric surgery may lead to bile reflux gastritis. When bile flows back into the stomach, components such as bile salts can damage the protective layer of the gastric mucosa, causing gastric mucosal inflammation and abnormal gastric acid secretion. Symptoms may include epigastric discomfort, nausea, and vomiting. It is recommended to use medications such as omeprazole enteric-coated tablets, lansoprazole enteric-coated tablets, and ranitidine hydrochloride capsules under medical guidance for treatment.

　　In daily life, attention should also be paid to adjusting dietary habits, maintaining a positive mindset, and adopting healthy lifestyle practices to prevent the occurrence of acid reflux associated with gastritis.
