What should I do if I have a bitter taste in my mouth and bad breath?

A bitter taste in the mouth accompanied by bad breath can be addressed from the following aspects: 1. Oral hygiene: Maintaining good oral hygiene is essential. Regular tooth brushing, flossing, and using mouthwash help remove food debris and bacteria from the mouth, reducing the occurrence of bad breath. 2. Dietary adjustments: Eat a light diet and increase intake of fiber-rich vegetables and fruits, such as mung beans, Chinese yam, pears, and lily bulbs, which help clear heat and detoxify the body. Avoid spicy and highly irritating foods to minimize irritation to the mouth. 3. Medication: If a bitter taste and bad breath are caused by indigestion, Helicobacter pylori infection, or spleen-stomach imbalance, appropriate medications should be taken under medical supervision, such as Jianwei Xiaoshi tablets, amoxicillin, or Niuhuang Qingwei pills. 4. Lifestyle habits: Maintain regular daily routines and avoid unhealthy practices such as staying up late or overexertion to support overall health.
