Bad breath can be divided into many types

One. Oral diseases: People suffering from oral diseases such as dental caries, gingivitis, periodontitis, oral mucositis, tooth decay, periodontal disease, etc., are prone to bacterial growth in the oral cavity, especially anaerobic bacteria, which decompose and produce sulfides, emitting a putrid taste, and producing bad breath.

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

Three. Drugs that can reduce saliva secretion, such as certain sedatives, antihypertensive drugs, atropine drugs, diuretics, and traditional Chinese medicine with warming and tonic effects.

Four. Dieting to lose weight, or not being able to eat due to illness, or decreased salivary gland function in the elderly, or decreased saliva secretion due to endocrine disorders during menstruation in women, is conducive to the growth of anaerobic bacteria, so bad breath occurs.

Five. Excessive psychological pressure, frequent mental stress leads to the parasympathetic nervous system of the body in a state of excitement, and the digestive glands, especially the salivary glands, are reflexively reduced, resulting in dry mouth, which is conducive to the growth of anaerobic bacteria and produces bad breath.

Six. Mental factors. There is no bad breath, and doctors and others do not smell it, but patients insist that they smell bad breath, and they have neurotic, obsessive-compulsive tendencies, and are more common in hypochondriasis. The psychology of such patients is very painful, so I hope that everyone will not discriminate against them.

Seven. Bad breath in young girls: Some women in the adolescent stage have ovarian insufficiency and low levels of sex hormones, and the resistance of oral tissues decreases, and they are prone to infection with germs and produce bad breath.

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

Nine. Gastrointestinal diseases, such as peptic ulcer, chronic gastritis, functional dyspepsia, etc., can be accompanied by bad breath. The incidence of bad breath in patients infected with Helicobacter pylori, which causes many stomach diseases, is significantly higher than that in uninfected patients, and after the eradication of Helicobacter pylori, the symptoms of halitosis are significantly reduced. The cause may be Helicobacter pylori infection, which directly produces sulfides, causing bad breath.

Ten. Dinner is too "heavy", eating too much or eating too much meat, greasy food or too much spicy and irritating seasoning, too much aroma and lightness, too short time between dinner and sleep, too much food in the stomach when sleeping, etc.

Eleven. Long-term constipation will cause symptoms of bad breath, bloating, loss of appetite, irritability and other autotoxic symptoms due to the inability to discharge harmful substances produced in the body in time and be absorbed into the bloodstream.
