What causes saliva to smell?

Everyone's saliva has a bit of odor, but the severity of the odor is different. Normal people's saliva is not completely odorless, it's just that the odor is very small and not obvious. Common causes of bad breath include:

1. Oral diseases: People with oral diseases such as caries, gingivitis, periodontitis, oral mucositis, tooth decay, and periodontal disease are prone to the growth of bacteria in their mouths, especially anaerobic bacteria, which decompose to produce sulfides, emit a corrupt smell, and cause bad breath.

2. Gastrointestinal diseases, such as peptic ulcer, chronic gastritis, functional dyspepsia, etc., may be accompanied by bad breath.

3. People who smoke, drink alcohol, drink coffee, and often eat spicy foods such as onions, garlic, leeks, or are addicted to stinky foods such as stinky tofu and stinky eggs are also prone to bad breath.

4. Dieting to lose weight, or being unable to eat due to illness, or the reduced salivary gland function of the elderly, or endocrine disorders in women during menstruation, which leads to reduced saliva secretion, is conducive to the growth of anaerobic bacteria, thus causing bad breath.

5. Bad breath in teenage girls: Some women in puberty have ovarian insufficiency and low sex hormone levels. The resistance of oral tissue decreases, making it easy to be infected by bacteria and cause bad breath.

6. Drugs that can reduce saliva secretion, such as certain sedatives, antihypertensive drugs, atropine-type drugs, diuretics, and traditional Chinese medicines with warming and tonic effects.

7. Patients with diabetic ketoacidosis, hepatic coma, and some respiratory diseases such as bronchitis, bronchiectasis, sinusitis, pharyngitis, tonsillitis, lung cysts, etc. may also cause bad breath.

8. Long-term constipation can cause harmful substances produced in the body to fail to be excreted in time and be absorbed into the blood, causing bad breath, abdominal distension, loss of appetite, irritability and other symptoms of self-poisoning.

9. Dinner is too "heavy", eating too much or eating too much meat, greasy food or too much spicy seasoning, too much strong flavor and not enough light food, dinner is too close to sleep, too much food is left in the stomach when sleeping, etc.

10. Excessive psychological pressure and frequent mental tension cause the body's parasympathetic nerves to be in an excited state, which reflexively leads to a decrease in the secretion of the digestive glands, especially the salivary glands, causing dry mouth, which is conducive to the growth of anaerobic bacteria and produces bad breath.
