Pneumonia fills the lung's alveoli with fluid, hindering oxygenation. The alveolus on the left is normal, whereas the one on the right is full of fluid from pneumonia. Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. [55] It is a type of pneumonitis (lung inflammation). [56]
They have an insidious onset of cough, progressive dyspnea, fatigue, and weight loss. This is associated with partial to complete but gradual reversibility. Avoiding any further exposure is recommended. Clubbing is observed in 50% of patients. Tachypnea, respiratory distress, and inspiratory crackles over lower lung fields often are present. [1]
Small and fast inhalations [6] Without proper treatment, pneumonitis may become chronic pneumonitis, resulting in fibrosis of the lungs and its effects: Difficulty breathing [3] Food aversion [3] Lethargy [8] End-stage fibrosis and respiratory failure eventually lead to death in cases without proper management of chronic pneumonitis.

White lung pneumonia is not a specific type of pneumonia, Dr. Ganjian says. “It is simply a term that has been used to describe pneumonia that appears white on chest X-rays,” he explains.
The object lodges in a small airway, and pneumonia develops in the obstructed area of the lung. Another cause of obstruction is lung cancer, which can block the flow of air. Lung disease - Patients with underlying lung disease are more likely to develop pneumonia. Diseases such as emphysema and habits such as smoking result in more frequent and ...
Since pneumonia can take a dangerous turn, it's important to know the earliest signs of it. Dr. Zweig says that, typically, pneumonia starts as a regular viral upper respiratory infection.
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
The respiratory illness caused by mycoplasma pneumoniae bacteria is often called walking pneumonia because it tends to be milder than other lung infections. Patients may feel run down, with a ...
