Pneumonitis is an inflammatory condition of the lung tissue often caused by inhalation of irritants, infections, or autoimmune disorders, leading to symptoms like cough, fever, and difficulty breathing. It is crucial to identify and manage the underlying cause to prevent progression to chronic lung disease or fibrosis.

Pneumonitis

Inflammatory condition

Lung tissue is a specialized biological structure designed for efficient gas exchange, composed of alveoli, bronchioles, and blood vessels. Its health is crucial for respiratory function and is affected by various diseases such as pneumonia, emphysema, and lung cancer.

Lung Tissue

Inhalation of irritants

Infections occur when harmful microorganisms, such as bacteria, viruses, fungi, or parasites, invade the body, multiply, and cause disease or damage. The body's immune response is crucial in fighting infections, but the effectiveness of this response can vary based on the pathogen and the individual's health status.

Infections

Autoimmune disorders occur when the immune system mistakenly attacks the body's own cells, tissues, or organs, leading to chronic inflammation and tissue damage. These disorders can affect almost any part of the body and often require lifelong management to control symptoms and prevent complications.

Autoimmune Disorders

A cough is a reflex action to clear the airways of irritants and mucus, often serving as a symptom of various underlying conditions such as infections, allergies, or chronic diseases. Understanding the cause and characteristics of a cough is crucial for effective diagnosis and treatment, as it can range from acute to chronic and be productive or non-productive.

Cough

Fever is a temporary increase in body temperature, often due to an underlying infection or illness, and serves as a natural defense mechanism to enhance the immune response. It is important to monitor the symptoms and underlying causes, as persistent or extremely high fevers may require medical attention.

Fever

Difficulty breathing

Underlying Cause

Chronic Lung Disease

Fibrosis is a pathological process characterized by the excessive accumulation of extracellular matrix components, primarily collagen, leading to tissue scarring and disruption of normal organ function. It is a common outcome of chronic inflammation and can affect various organs, including the liver, lungs, kidneys, and heart, often resulting in significant morbidity and mortality.
