Heartburn is a recurring burning sensation or feverish feeling in the xiphoid process or behind the sternum, and is commonly associated with conditions such as reflux esophagitis and peptic ulcer. Foods that cause acid reflux to worsen or stimulate acid secretion in the stomach, such as chili peppers, ginger, doughnuts, and chocolate, are not recommended. Try not to eat spicy and stimulating foods such as chili peppers, peppercorns, onions, ginger, garlic, and peppers on a regular basis, as they may lead to increased acid reflux and aggravate this symptom. Try not to eat greasy and sugary foods such as doughnuts and panko, or foods high in sugar such as chocolate, so as not to stimulate the secretion of stomach acid. You should also avoid cold and raw foods, and eat less ice cream in summer and cold fruits in winter to reduce the irritation to the gastrointestinal tract. If this symptom persists or worsens, it is recommended to go to the hospital to clarify the cause of the disease and then under the guidance of the doctor for treatment.
