Phlegm has a foul smell

Introduction When the smell of sputum is foul-smelling, lung inflammation is accompanied by anaerobic infection. Found in lung abscesses, bronchiectasis and lung malignant tumors and other lung diseases. Late malignant tumor of the lung: the symptoms worsen during the worsening period, the body temperature rises, the cough and cough increase, and there is often a foul smell. There is a stench that indicates anaerobic infection in the lungs. If the respiratory tract is not discharged in time, resulting in poor exhalation and difficulty in breathing, it may develop into emphysema; coughing, repeated coughing may cause alveolar changes leading to hypofunction; in some patients, sputum is also antigenic and can cause allergies Asthma, tissue clots of necrosis.

The diagnosis of lung abscess cannot rely solely on the results of pneumonia-like symptoms or examinations. Pulmonary abscesses should be suspected when pneumonia-like symptoms occur in people with nervous system diseases, alcohol abuse or drug abusers, and those with various causes of consciousness. Chest X-rays often show lung abscesses. However, if the X-ray examination only shows a lung abscess, CT is usually required. Sputum culture helps identify pathogens that cause lung abscesses.

Bronchiectasis: Chronic cough and cough with a large amount of purulent sputum accompanied by anaerobic infection, may have a foul odor, patients often change their position (such as getting up in the morning or sleeping at night) coughing, sputum more, when changing In the body position, the secretions come into contact with the normal mucosa, causing the cough to reverse, causing a large amount of purulent sputum to cough up.

Differential diagnosis

There is a smell of feces: the underarm abscess penetrates into the lungs.

There is a stench of sputum: lung abscess, advanced lung cancer.

There is bloody smell: tuberculosis, lung cancer.
