Bitter taste in the mouth may be caused by the following reasons:

1. Hormonal imbalance: When experiencing high levels of mental stress, the body's hormone secretion may become abnormal. This hormonal imbalance can affect the taste nerves, resulting in a bitter taste in the mouth. This situation commonly occurs during periods of intense work pressure or after significant life events.

2. Gingivitis: This condition can alter the oral environment, promoting bacterial growth, which may lead to a bitter taste.

3. Excess heat in the stomach: This may be related to gastrointestinal conditions such as esophagitis or gastritis. These conditions can cause abnormal bile reflux, allowing bile to enter the mouth and cause a bitter taste.

4. Irregular eating habits: If food remains in the gastrointestinal tract for an extended period, it can have adverse effects.

Maintaining good lifestyle habits, such as regular meals, sufficient sleep, moderate exercise, and stress reduction, can also help alleviate symptoms of a bitter taste in the mouth.
