In fact, there are many reasons for bad breath and simply cleaning your mouth may not solve the problem.

People who regularly smoke, drink alcohol, drink coffee, eat strong-flavored foods such as onions, garlic, leeks, etc. will have bad breath.

In addition, here are 5 reasons for bad breath:

1. Low saliva secretion

Saliva has antibacterial and bactericidal effects. If you often like to breathe through your mouth, you will have less saliva, which can easily cause bacteria to increase and cause bad breath.

2. Problems in the oral cavity

Tartar, tooth decay, periodontitis, tonsil stones, etc. will all affect your breath.

3. Stomach disease

HP bacteria infection is the most common cause. This is a type of bacteria that is highly pathogenic, is the culprit of stomach ulcers, and also creates foul-smelling gas.

If you often suffer from acid reflux and belching, you should go to the hospital to check if you are infected with this type of bacteria.

4. Spleen and stomach disorders

According to the theory of traditional Chinese medicine, bad breath is caused by dysfunction of internal organs, and the key lies in the dysfunction of the spleen and stomach.

Symptoms such as irregular stools, sticky mouth, bloating, white tongue, etc. need to be checked and adjusted.

5. Metabolic diseases

Diabetes, liver disease, etc. seem to have nothing to do with bad breath, but they must be paid close attention to. Due to metabolic problems, bad breath is a signal that the body sends out to warn of the above diseases.

What diseases cause bad breath?

1. Sour smell

A sour taste in the mouth is the most common problem of indigestion. Too much food remains in the stomach, after being fermented by digestive juices, enzymes, bacteria, etc., it will have a sour taste. In addition, people with bile reflux, too much acidity will also have a sour taste in the mouth, need to regulate the spleen and stomach, treat the stomach.

2. Rotten egg smell

If your mouth smells like "rotten eggs", it is usually due to oral problems. The accumulation of bacteria in the teeth, tongue, tonsils, etc. will produce volatile sulfides and other gases, which smell similar to rotten eggs and vegetables.

If you smell this smell in your mouth, you need to consider whether you have periodontal disease, tooth decay, tonsil stones or insufficient saliva secretion in your mouth.

In particular, tonsil stones are hidden relatively deep, difficult to detect, and daily oral hygiene is not effective. We can observe our tonsils, if there are some "white spots" as shown below, it may be tonsil stones.

Note: If you detect tonsil stones, do not use tools to remove them on your own, as this can easily cause bleeding, infection, and acute tonsillitis. You must go to the hospital for treatment by a specialist.

3. Rotten apple smell

The smell of rotten apple in the breath is a characteristic of diabetic patients, because the metabolism of diabetic patients is disturbed, acetone will accumulate in the lungs and be excreted through the breath.

Therefore, if you notice a clear smell of rotten apple in the breath, you must pay attention to this disease.

4. Stool smell

When kidney function is damaged, metabolic waste produced by the body is not processed and excreted in time, it will "escape" from the lungs, the mouth will have a smell of feces like urine, very unpleasant. This is a serious condition.

When detecting this abnormal smell, you should promptly go to the hospital to check liver and kidney function, this may be an early sign of the disease.
