Bad breath after waking up

Maybe everyone has had this experience, that is, waking up with bad breath. This phenomenon is related to many aspects. Some people have bad breath due to respiratory diseases, such as tonsillitis or pharyngitis, which is caused by protein flowing into the pharynx and decomposing it. Stomach problems can also cause people to have bad breath when they wake up in the morning. Regardless of the cause, it is related to the disease, and the bad breath will disappear after the disease is treated.

1. Respiratory diseases

Upper respiratory tract diseases such as sinusitis, tonsillitis and pharyngitis will secrete a large amount of protein-containing mucus, some of which forms nasal mucus and the rest flows from the nasal passages into the oropharynx. Some of this mucus adheres to the back of the tongue or the oropharynx, and when the protein breaks down, it produces a putrid smell.

2. Stomach disease

When the pyloric part of the stomach is narrowed or obstructed, food stays in the stomach for too long and produces a sour, smelly, and rotten odor that is emitted through the mouth. Gastric diseases such as reflux esophagitis can also cause pathological bad breath, and the vomitus adhering to the mouth and throat will continuously release "sour gas". Usually, bad breath can be significantly improved after active treatment of stomach problems.

3. Lung cancer

Lung infection, bronchitis, lung abscess, chronic tracheitis, pneumonia, emphysema and even lung cancer can cause bad breath to varying degrees. These odors are mostly caused by mucus that accumulates in the lungs. Among them, patients with lung abscess often have rancid bad breath. Such patients often have fever, purulent sputum, etc., and chest X-ray examination can generally confirm the diagnosis; patients with hemoptysis due to tuberculosis and hemoptysis due to bronchiectasis often have bloody bad breath; patients with advanced lung cancer often have rancid odor in their mouth and exhaled breath.

The above is an introduction to what causes bad breath after waking up. In short, when we do not pay attention to oral hygiene, it is most likely to cause bad breath. Therefore, everyone must remember to brush their teeth in the morning and evening. If persistent bad breath occurs, you should go to a regular hospital for treatment. I hope this article can help you.
