Gastric ulcers can cause belching, throat burning, and discomfort, especially after talking or eating. To help manage it, avoid spicy, oily, or acidic foods, eat smaller meals, and do not lie down immediately after eating. Over-the-counter antacids or acid reducers may help, but it is important to see your doctor for proper treatment, as ulcers often need prescription medicine to heal and prevent complications. Avoid smoking, alcohol, and stress, which can worsen symptoms.
