What is the reason why saliva is yellow

Yellow saliva is usually caused by infection with Helicobacter pylori. It may also be caused by bile reflux or oral disease.

1. Infection with Helicobacter pylori: Healthy saliva is generally transparent, and may also be slightly whitish. If the saliva turns yellow, you need to pay enough attention. It may be caused by abnormalities in some parts of the body. For example, infection with Helicobacter pylori can cause gastrointestinal diseases in patients, which will have an adverse effect on the normal digestion of food, and may be accompanied by symptoms such as vomiting or acid reflux. When some food in the body cannot be completely digested, it will cause the saliva to turn yellow.

2. Bile reflux: Bile reflux is related to gastrointestinal problems and other factors. It may also be caused by irregular diet, which will prevent food from entering the stomach and intestines smoothly. It will also induce gastric erosion, and in the later stage, it will discharge odors or foreign objects from the intestines, which will eventually lead to saliva contamination and turn yellow.

3. Oral diseases: such as periodontitis, oral ulcers and other diseases, which will breed a lot of bacteria in the mouth, resulting in symptoms of oral infection and yellow saliva. You should choose the appropriate treatment method according to your condition. You should pay attention to personal hygiene, brush your teeth frequently with a soft-bristled toothbrush, and rinse your mouth with mouthwash after meals.
