To help relieve your gastric reflux, you can try making some lifestyle changes. Avoiding tea and coffee for a few days may help reduce your symptoms. Other measures you can take include avoiding eating and drinking three hours before bedtime, elevating the head of your bed, avoiding certain foods and drinks, eating smaller meals more frequently, and quitting smoking. If these measures are not effective, you can consider using an over-the-counter medication like Gaviscon™. If your symptoms persist after two weeks, or if you experience vomiting, difficulty swallowing, bleeding in your stool or vomit, or weight loss, it's important to consult a healthcare professional.
