There is a relationship between bad breath and dampness. Under normal circumstances, simple dampness does not cause bad breath, only when dampness and heat are intertwined together will cause bad breath. When dampness and heat are intertwined in the spleen and stomach, dampness and heat hinder the transportation of the spleen and stomach, and the transportation of water and grains is not as good as it should be, resulting in the generation of turbid qi in the stomach. The turbid qi that is generated rushes upwards under the vaporization of heat and bad breath occurs. In addition, if simple dampness blocks the qi of the middle jiao, affecting the transportation of the spleen and stomach, leading to food stagnation in the stomach (food stagnation in the stomach), and the failure of putrefaction (the initial digestion of food to form surimi), and then the turbid qi goes upward, bad breath will also occur. In addition to dampness-heat and food stagnation in the stomach, stomach fire can also cause bad breath. When stomach heat is blazing, the food is rotting too much, and the turbid gas in the stomach steams up, so bad breath will appear. If the body of the above symptoms, you should go to the hospital in a timely manner to clarify the cause of the disease, not to be taken lightly, so as not to delay the condition.
