First, the cause of bad breath
1, menstrual hormone fluctuation
During menstruation, the blood sex hormone level fluctuates greatly, which will affect the metabolism of periodontal tissue, lead to the weakening of oral resistance to germs, and easily be infected by germs, thus leading to bad breath or slight oral odor aggravation.
2. Upper respiratory diseases
Upper respiratory tract diseases such as sinusitis, tonsillitis and pharyngolaryngitis will secrete a large amount of mucus containing protein, some of which will form nasal mucus, and the rest will flow into the pharynx from the nasal passage. These mucus partially adhere to the back of the tongue root or oropharynx, and when protein is decomposed, it will produce bad smell.
3, stomach trouble
When the pyloric part of the stomach is narrow or obstructed, food will be left in the stomach for too long, which will produce a sour and rotten smell, which will be emitted through the mouth. Gastropathy such as reflux esophagitis can also lead to pathological halitosis, and the vomit adhering to the mouth and throat constantly releases "sour gas".
4, diabetes pyruvate poisoning
If the blood sugar exceeds the standard and is not controlled, the decomposition of fat in the body will produce ketone bodies, among which α -ketoglutarate will give off a sour rotten apple flavor. When exhaling this smell, you need to seek medical attention in time, otherwise your life will be in danger.
5, uremia
Patients with chronic nephritis or nephropathy, because there is no urine, some toxic substances can not be excreted and remain in the blood, which will make the gas exhaled by patients emit urine smell, which is a signal that the condition tends to be critical.
6. Liver failure
The liver's metabolic ability is weakened, the ability to decompose toxins is reduced, and blood ammonia is increased, resulting in a slightly sweet excrement odor in the mouth, and the metabolic ability of some branched-chain amino acids in the body is weakened, which will also lead to rotten apple flavor.
7. Lung cancer
Lung infection, bronchitis, lung abscess, chronic bronchitis, pneumonia, emphysema and even lung cancer can all cause bad breath to varying degrees. These smells are mostly caused by mucus accumulated in the lungs, and people with pulmonary tuberculosis and bronchiectasis and hemoptysis often have bloody breath and bad breath; Patients with advanced lung cancer often have foul smell in mouth and breath.
Second, the elimination of bad breath precautions
Excluding these causes, the occurrence of halitosis is mostly related to oral hygiene. Then, MM must review what they have done in oral hygiene at ordinary times.

Stick to brushing your teeth in the morning and evening, rinse your mouth after meals, brush your teeth correctly, and brush the inner wall of your mouth after brushing your teeth to understand the correct use of dental floss and mouthwash.
2. Replace the toothbrush regularly.
Toothbrushes show that bacteria are most likely to grow. Some studies say that toothbrushes are even dirty in the toilet, and they should be washed with hot water before and after use, and the toothbrush should be changed at most once every three months.
3. Change a toothpaste.
If you use the same toothpaste for a long time, the oral germs will be adaptive, and the cleaning effect will gradually decrease. The oral problems corresponding to different toothpastes are also different. You may wish to try another toothpaste at intervals.
4. Improve your mood
Bad mood will also affect oral hygiene, especially bad mood during menstruation, which will lead to menstrual disorder and bad breath, so we should pay attention to maintaining a stable mood.
