It is a descriptive term which may be used for inflammation related to a bacterial infection or non-infectious causes (e.g. pancreatitis). Most commonly, it is used in contradistinction to a "walled-off" pus -filled collection ( abscess ), although a phlegmon may progress to an abscess if untreated.
A major illness associated with excess phlegm is acute bronchitis. A major symptom of acute bronchitis is an excess amount of phlegm and is usually caused by a viral infection, and only bacterial infections, which are rare, are to be treated with an antibiotic. [12]
An abscess is a collection of pus that has built up within the tissue of the body, usually caused by bacterial infection. [6] [7] Signs and symptoms of abscesses include redness, pain, warmth, and swelling. [1] The swelling may feel fluid-filled when pressed. [1] The area of redness often extends beyond the swelling. [8] Carbuncles and boils ...
Having green, yellow, or thickened phlegm (sputum) does not always indicate the presence of an infection. Also, if an infection is present, the color of the phlegm (sputum) does not determine whether a virus, a bacterium or another pathogen has caused it. Simple allergies can also cause changes in the color of the mucus. [1]
Treating allergy symptoms with over-the-counter medication, saline spray, and, if warranted, allergy medication or injections from your doctor, may also help reduce GI symptoms as a result.
Lung abscess is a type of liquefactive necrosis of the lung tissue and formation of cavities (more than 2 cm) [1] containing necrotic debris or fluid caused by microbial infection. This pus -filled cavity is often caused by aspiration, which may occur during anesthesia, sedation, or unconsciousness from injury.
It can result in a thick exudate of mucus and white blood cells caused by the swelling of the mucous membranes in the head in response to an infection. It is a symptom usually associated with the common cold, pharyngitis, and chesty coughs, but it can also be found in patients with adenoiditis, otitis media, sinusitis or tonsillitis.
However, some researchers argue that the flow of mucus down the back of the throat from the nasal cavity is a normal physiologic process that occurs in all healthy individuals. [1] Some researchers challenge post-nasal drip as a syndrome and instead view it as a symptom, also taking into account variation across different societies.
