What causes stomach burning, dry mouth, and a bitter taste?

Heartburn, dry mouth, and a bitter taste may be caused by factors such as unhygienic diet, reflux esophagitis, or gastritis. Targeted treatments are required, with specific analysis as follows:

1. Unhygienic Diet

Long-term consumption of spicy and irritating foods—such as barbecued items or hot pot—and frequent alcohol drinking can lead to excessive accumulation of food residue in the stomach, making digestion difficult. This may result in symptoms including heartburn, dry mouth, and a bitter taste. It is recommended to eat light, easily digestible meals and adopt a pattern of eating small portions more frequently throughout the day.

2. Reflux Esophagitis

Reflux esophagitis is usually caused by excessive gastric acid, which impairs normal stomach function and leads to these symptoms. Under medical guidance, medications such as omeprazole enteric-coated capsules or lansoprazole enteric-coated tablets may be used for treatment.

3. Gastritis

Chronic heavy drinking or overeating can irritate the gastrointestinal mucosa, leading to gastritis and resulting in these symptoms. Under a doctor’s supervision, medications such as domperidone tablets or mosapride citrate dispersible tablets may be prescribed for treatment.

In addition to the above causes, conditions such as myocardial ischemia, coronary heart disease, or stomach cancer may also produce similar symptoms. It is recommended to visit a hospital to determine the underlying cause and receive appropriate, targeted treatment.
