Introduction
In general, a bitter taste in the mouth may be caused by dietary habits, dehydration, poor oral hygiene, indigestion, chronic gastritis, etc. It can be treated through general management, medication, and other approaches. It is important to maintain a balanced diet, avoid excessively oily and spicy foods, practice good oral hygiene, clean teeth regularly, and ensure adequate fluid intake.
Generally, a bitter taste in the mouth may be caused by dietary habits, dehydration, poor oral hygiene, indigestion, chronic gastritis, and other factors. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:
1. Dietary Habits
Consuming spicy, greasy, or excessive foods—especially coffee and alcohol—can lead to a bitter taste in the mouth. It is advisable to adjust the diet by reducing intake of spicy and greasy foods, increasing consumption of fresh vegetables and fruits, and maintaining a light diet.
2. Dehydration
Insufficient water intake reduces saliva production, disrupting the bacterial balance in the mouth and potentially causing a bitter taste. Increasing daily water consumption helps maintain adequate hydration.
3. Poor Oral Hygiene
Inadequate oral hygiene practices, such as incomplete tooth brushing or failure to rinse after meals, can lead to food residue remaining in the mouth, promoting bacterial growth and resulting in bad breath and a bitter taste. Maintaining good oral hygiene—including brushing teeth morning and night and rinsing after meals—is essential.
4. Indigestion
Poor eating habits and other factors may cause indigestion, leading to prolonged retention of food in the stomach, excessive gastric acid secretion, and bile reflux into the esophagus or mouth, resulting in a bitter taste. This may be accompanied by symptoms such as bloating and acid reflux. Under medical guidance, medications such as omeprazole enteric-coated capsules, mosapride citrate tablets, or Xiangsha Yangwei Pills may be used for treatment.
5. Chronic Gastritis
Chronic gastritis is associated with physiological factors such as excess stomach acid and Helicobacter pylori infection. Long-term inflammation can lead to indigestion and gastric acid reflux, causing a bitter taste in the mouth, along with possible symptoms like stomach discomfort and belching. Under a doctor's supervision, patients may take medications such as amoxicillin granules, cefaclor dispersible tablets, or rabeprazole sodium enteric-coated tablets.
In daily life, it is important to maintain a balanced diet, avoid overly greasy and spicy foods, practice good oral hygiene, have teeth cleaned regularly, and ensure sufficient fluid intake.
