Non-vegetarian food is often richer in fats and spices, which can trigger excess acid production and delay stomach emptying, irritating your stomach lining. Since your prescribed medications, Pan D (pantoprazole with domperidone) and Sporlac DS (lactic acid bacilli), are no longer providing relief, please consult your doctor for a detailed evaluation rather than self-medicating. They may need to investigate for conditions like acid reflux, ulcers, or gallbladder issues, and adjust your treatment. For now, stick to bland, easily digestible, smaller meals, avoid heavy foods, and stay well-hydrated.
