What Are The Reasons For Bad Breath ? Bad breath may be caused by many reasons :

1. Diet breath

Eating certain foods, such as garlic, onions, leeks, tofu and other food has a specific smell itself, after eating these foods, food residue remaining in the oral cavity may be issued the corresponding odor.

2. Corruption of Foreign Bodies

Remaining food residues in the Chifeng in decay by bacterial action resulting from the smell.

3. Tissue Necrosis

Human tissue mainly  composited by protein, corruption produce hydrogen sulfide and other odor after decomposition.

4. Bacteria breed

Some of the oral cavity and respiratory tract bacteria break down proteins, starch, producing a large number of bacterial metabolic products, such as indole stamp, sulfur and ammonia hydrogen-based class, etc. can cause bad breath.

5. The substances contained in blood

Diabetic ketoacidosis, uremic acidosis, the blood ketone, urea composition to increase the blood flow through the alveoli will be contained in the ketone decomposition of urea and some other gas distribution with the in vitro, so patients can have mouth odor or rotten apple smell of acetone.

The physiological factors

• Diet breath: If you drink, the smell of alcohol, smokers of cigarette smoke, fresh garlic, garlic odor after oral residual.
• Sleep at night after getting up to bad breath.
• Hunger and long-term fasting can also bring a strong halitosis.
• Some people can occur bad breath during pregnancy and menstruation .

The pathological factors

• Oral disease periodontal disease, caries, black hair tongue disease, oral necrotizing inflammation pericoronitis, oral cancer necrosis.
• The nasopharynx disease, suppurative maxillary sinusitis, atrophic rhinitis, acute tonsillitis, angina, pediatric nasal foreign body.
• Systemic diseases of other organs, such as indigestion, gastritis. Bronchiectasis secondary pulmonary infection, lung abscess, leukemia, platelet reducing disease, agranulocytosis, diabetes, lead, mercury, poisoning the town and organic matter may have unusual odor

Commonly, most of the causes stem from the mouth or mouth area. In this article I will outline the seven most common causes.

1. Severe Dieting

Prolonged starvation can cause a fouled breath caused by ketoacidosis.

2. Gum Diseases
Gum disease is a result of bacteria living in areas that are are not accessible by toothbrushes and will cause halitosis.

3.Tooth Decay
Decaying teeth are also a large cause. The decay and the bacteria that are produced from it will cause a foul smell.

4. Smoking
Nicotine, tar and other foul smelling substances in mouth as a result of smoking cause the very recognisable smokers breath.

5. Food particles
Food that is left between the teeth and on the surface of the tongue will be a major cause of this problem for a few reasons, but mostly because the bacteria in the mouth feed on these food particles, and they will produce waste which causes a bad smell.

6. Diet
What we eat can play an important role in how our breath can smell. Food such as garlic and onion are well known for not being good for the breath, however it is less known that proteins can play a part in the production of bad breath for a couple of reason including the fact that bacteria feed on protein and secondly that some people are allergic to proteins and this allergy can produce a bad mouth odour.

7. Dry mouth (Xerostomia)
Saliva is produced by the mouth and act as a natural way for the mouth to flush away any waste as well as acting in an anti-bacterial fashion. When saliva production is decreased (commonly when we sleep we don’t produce as much saliva, or when we are de-hydrated) bacteria builds up in the mouth. As well, there is a build up of plaque which favours the growth of odour producing organisms.

The principal bad breath cause is associated with bacteria in the mouth. They are anaerobic, which means “without oxygen”. As saliva provides oxygen the lack of saliva with a dry mouth makes a more favorable environment for the bacteria to increase, The bacteria create sulfurous compounds, such as hydrogen sulfide (the bad egg smell)，leading bad breath.

Dry mouth is the most causes of bad breath:

Dry mouth means lack of saliva, which also means that old food is not washed away, and saliva also helps in neutralizing acids. Saliva also performs the very necessary task of flushing out the mouth, and removing food particles, so any reduction in saliva flow inhibits this action.

Saliva can be reduced for a number of reasons.

• natural causes
  The flow of saliva reduces naturally as we get older, making us more prone to bad breath.when we are dehydrated, the moisture in the mouth reduces naturally.when asleep, people will have their mouths open, maybe even snoring, and this will dry out the mouth. This contributes to the “morning breath” syndrome.
• medications
  Dry mouth can also be caused by medications for various problems. The most common is probably the antihistamine, taken to relieve allergies. Some others include high blood pressure and depression medicines. Other things that can be ingested that affect the dryness of the mouth include alcohol and mouthwashes that contain alcohol.
• cigarette smoking
  One of the many problems associated with cigarette smoking is dry mouth, for many reasons unrelated to bad breath, it is wise to avoid smoking, as has been documented extensively elsewhere. With a predisposition to bad breath, however, the habit of smoking virtually guarantees that you will suffer from bad breath.

Certain diseases and illnesses can similarly contribute to bad breath. Any infection that affects the respiratory tract can be a cause of bad breath, as well as many other diseases.

Bad breath causes, summarized in the following reasons:

1. Oral health

Bad oral health, often lead to plaque deposited on the surface of the teeth or the junction of gums and teeth. Dental plaque is the main reason for caries and periodontal disease, but also one of the causes of bad breath. Because the local plaque accumulation is likely to be a good place to survive anaerobic bacteria, which is also the direct cause of bad breath.

2. Dry mouth

Dry mouth is the most direct cause of bad breath. When dry mouth, the mouth of the oxygen-free environment is very suitable for the breeding and excessive growth of these anaerobic bacteria. And will decompose to produce sulfide, given the taste of corruption.

This is the root cause of bad breath, most people fall asleep at night, due to reduced function of the oral cavity, saliva secretion reduce very conducive to the breeding of anaerobic bacteria, so there will be the morning mouth odor.

3. Bad diet

Some foods also put pressure on living habits bad breath symptoms. Like spicy foods such as onions, garlic, dairy products, sugar, etc. will break out in the oral cavity sulfide and bring mouth odor. Drinking coffee, drinking, smoking  will also increase bad breath.

4. Nasal Disease

Used intranasal net will appear bad breath. With intranasal drops the net a long time will affect the nasopharyngeal mucosa, the mucous membrane mucus also decomposition of sulfides, leading to bad breath.

5. Secretions between the tongue papillae of the back tongue

If the secretions are much more, the secretions deposited on the surface of the formation of the tongue tongue, as in the anaerobic environment, anaerobic bacteria are very active, and continuously break down to produce sulfide, can lead to mouth odor

6. Psychological factors, stress, tension

Tension, pressure will make the body parasympathetic excited state, reflex salivary secretion appeared reduced, leading to dry mouth.

7. Digestive Diseases

Digestive diseases, such as constipation, stomach pain, dyspepsia, acute and chronic gastritis, duodenal ulcer, hepatitis, H. pylori infection may also encourage anaerobic bacteria in an active state, or directly from sulfide.

8. Long-term medication

Some drugs long-term use can also cause bad breath, such as some antidepressant drugs, anti-hypertensive drugs, anti-allergy medicine, anti-tissue amines, hormone drugs, progesterone drugs will increase the dry mouth symptoms.  Indirectly lead to mouth odor. In addition, the prolonged use of antibiotics and sometimes may also be beneficial to the body to kill bacteria, leading to imbalances in the body bacteria, anaerobes increased, causing bad breath.

9. Genetic

Sometimes, there are also bad breath hereditary genetic factors. A family is often common bad breath symptoms, but the exact cause is still in the research stage.

Nasal disorders will affect the tone, when suffering from allergic rhinitis, empyema, nasal swelling, nasal septum deviation disease processes, the nasal secretion of fluid back into the nasopharynx, that is, “nose-drain” phenomenon, leading nasopharyngeal inflammation , then causing bad breath. With regard to the treatment of bad breath, we must take full account of the health status of the nose.

In fact, in normal circumstances, the secretions produced by the nasopharyngeal area pay the role of lubricating mucous membrane, to remove foreign bodies and to prevent infections. However, this mucus (secretions) with a large number of accumulation, or the viscosity is too high, will be attached to the nasopharynx, increase the sensitivity, not only cause bad breath, but also bring the nasopharynx syndrome.

This secretion is constituted by a large number of proteins, which are good meals to the  anaerobic bacteria in the mouth. Therefore, patients with rhinorrhea are often accompanied by bad breath.

With regard to bad breath treatment, should pay attention to the nasopharynx area, in particular, observe the phenomenon of whether there is rhinorrhea.

Diabetes can affect the human body functions in many ways leading to bad breath, here give you a detailed analysis mainly from five aspects:

Glucose

High blood sugar is an obvious condition of diabetes, maybe it will be noted, blood glucose levels and bad breath have a certain association. The excess glucose in the system may make it harder for the body to rinse away germs and bacteria, both of which are leading causes of mouth odor.

Endocrine disorders

Diabetes makes the endocrine disorder, reduce the amount of insulin secretion, difficult to break down carbohydrates, leading metabolism of fat actively, resulting acetone composition, and through the lungs, discharge from the mouth and nasal. This gas is what we call bad breath.

Dehydration

Most people who have diabetes find that they also have severe cases of dry mouth.  Diabetics are often very dehydrated; they are always thirsty and urinate frequently. Germs and bacteria can dry on the skin inside the mouth, on the tongue, and on the teeth.  Saliva helps to rinse away these germs and bacteria that cause bad breath; when you have dry mouth because of diabetes, then you’re likely to have bad breath as well.

Oxygen

High blood sugar easily lead to capillary congestion, lack of oxygen supply to the oral tissues, leading to the anaerobic bacteria that may lead to bad breath thrive. At this time not only lead to bad breath, but also ulcers, inflammation and other oral diseases occur. Moreover, according to experts, the survey showed that patients with diabetes compared with non-diabetic patients, more likely to lead to bad breath 2 ~ 3 times.

Chronic Complications

Chronic complications of diabetes can be divided into vascular system disease and peripheral nervous system diseases. Severe cases can lead to hypertension, myocardial infarction, atherosclerosis and other diseases. Diabetic patients with neurological disease, as peripheral nerve damage can easily lead to periodontitis, gingivitis, mouth ulcers and other oral diseases, which cause bad breath is one of the reasons.

Therefore, patients receiving treatment for diabetes, should pay attention to oral administration, if necessary, to the hospital for a detailed diagnosis and treatment.

Here are some foods that may cause bad breath:

• Easily fermented foods

After eating easily fermented foods like garlic, onions, green peppers, onions, ginger, pepper and so on, easier to produce gas, and also likely to cause bad breath.

• Greasy foods

Those people like to eat fatty foods with animal fats were more likely to get angry, and the fime of the foods remain in the stomach will be extended, leading to bad digestion.

• Overeat

Overeat heavier the burden of gastrointestinal and affect the digestive functions, resulting in acute, chronic gastroenteritis, which is a source of bad breath.

• Tobacco and Alcohol

Smoking and drinking, the most direct is to cause bad breath, is not only easy to get angry, affecting gastrointestinal motility and liver function, can also cause coughing.

Bad breath or halitosis as it is medically termed is caused by many factors, one of which is the food you eat. Mouth saliva has enzymes which interact with food to give off mouth odor. It also picks up the odor from food after a couple of hours from which it’s eaten.

Here are some food that can cause bad breath:

• Food with cellulose is one of the factors causing bad breath.

• Food that rich in starch, carbohydrates gives out strong mouth odors.

• Coffee and alcohol are both causes of bad breath

• Garlic and Onions are famous for their pungent odor. When their natural flavor mixes with mouth saliva and digestive acids, they give out a bad smell in the mouth.

• Foods high in proteins cause bad odor. Proteinis found in Meat, fish and seafood, eggs, and dairy foods. cereal grains, peas, beans, and lentils are a so a source of protein as are the ingredient of foods like cakes and pies.

If you don’t brush your teeth, food particles get stuck between the teeth reacts with mouth bacteria causing bad breath.

Bad breath is mouth abnormal smell, youself and the people around can smell. Bad breath caused by many reasons, usually summed up as food-borne, air-borne, pathogenic nature, habits.

Such as to eat onion and garlic, salt and other fishy food, long-term smoking alcoholics, suffering from periodontitis, pay little attention to oral hygiene, chronic sinusitis, lung disease, gastrointestinal diseases, diabetes, cancer, and other factors can produce different strong bad breath. However, the bad emotions can also cause bad breath, this factor is often overlooked by everyone.

In the psychological clinic, there is a very common phenomenon and many of them have psychological distress in newly diagnosed patients to treatment, the psychiatrist can find a special halitosis patients. Although psychologists can not have any care about the smell of this reaction, the patient is very sensitive to their own bad breath. They blocked both hands unconsciously live their own mouth and also often in the observation of a doctor of their own bad breath whether it be dislike.when they talk with other people.  After a period of treatment, when the patient’s psychological problems have improved, improved mood, bad breath, also will be significantly reduced or disappeared.

Family members accompanied the patient to see the doctor talking about the patient’s bad breath, they also share that their have a direct link between the patient’s state of mind and the degree of bad breath.

In modern medicine, bad breath have also been classified in the range of psychosomatic illness. Modern medicine also consider that psychological factors especially the bad state of mind can lead to bad breath.

To prevent bad breath, in addition to dinner and bedtime brushing, mouthwash, maintain oral health, with refreshing aromatic agent, the basic method is to remove the basic causes. We will not only treat the organic diseases,  but also pay attention to treatment of psychological barriers.  Do your best efforts to improve the emotional and adjust the mental to a good condition.

How to determine whether you bad breath is caused by helicobacter pylori infection ? According to medical conditions and personal economic situation of choice diagnostic methods:

1. Non-invasive method:

• blood and check anti-Helicobacter pylori antibodies.
• C13-breathing Experiment: accurate but the price higher.

2. Invasive method:

• rapid urease determination when having endoscopy examination.

The treatment of Helicobacter pylori eradication many ways, mainly acid-suppressing drugs, antibiotics and bismuth and so on. Must be under the guidance of a doctor to select the program with  high efficacy and little side effects .

Helicobacter pylori infection caused a high incidence of bad breath, With an effective anti-Helicobacter pylori treatment, your bad breath can be reduced and treated.

Improve the gastrointestinal tract of Bifidobacterium, can treat your bad breath. Soybean oligosaccharides, isomaltooligosaccharide fructooligosaccharides such as Bifidobacterium factor, have good effect for the treatment of bad breath.
