A burning sensation in the stomach while eating, along with burning of the tongue and difficulty tolerating warm or spicy food, may be related to acidity, gastritis, acid reflux, vitamin deficiencies, oral irritation, or sometimes fungal or allergic conditions affecting the mouth. Spicy foods, hot drinks, tobacco, alcohol, and stress can worsen these symptoms. Doctors commonly prescribe acid-reducing medicines, such as proton pump inhibitors or antacids, to reduce stomach irritation and acidity. If the tongue burning is related to mouth inflammation or a vitamin deficiency, supplements such as vitamin B12, iron, or folic acid may sometimes be needed after proper evaluation. Mouth-soothing gels or medicated mouthwashes may also help reduce discomfort temporarily. For now, try to avoid spicy, oily, very hot, or acidic foods. Eat soft and bland meals, drink enough water, and avoid smoking or alcohol if applicable. Maintaining good oral hygiene is also important. If your symptoms persist for more than a few weeks, worsen over time, or are accompanied by mouth ulcers, weight loss, vomiting, or difficulty swallowing, please consult a doctor or dentist for a proper examination to identify the exact cause and receive appropriate treatment.
